李平（重庆建峰浩康化工有限公司，重庆 408017）
摘 要：高亚氨基甲醚化三聚氰胺树脂既保留了一定量的未反应的活性氢原子，又残余了一定的羟甲基，因此产品的综合性 能最好而被广泛应用于涂料中。目前国内现有的合成工艺技术不是很成熟且质量不稳定，难以大规模生产。文章作者通过分析 研究，提出了一条新的用甲醇醚化按一定比例混合的三羟甲基三聚氰胺和六羟甲基三聚氰胺的工艺路线。经过实验探索和优化， 验证了工艺的可行性，工艺稳定且产品的质量指标达到了国内先进水平，有望打破国外技术的垄断。

5-7主体树脂和氨基树脂的官能团——主体树脂官能点的类型
5主体树脂和氨基树脂的官能团——主体树脂官能点的类型CYMEL303反应的有醇酸，聚酯，丙烯酸，环氧及其它成膜物，他们必须含有一个或多个官能团——羟基，羧基，酰胺基。
谈到聚合物树脂的配方即是艺术又是科学，有相当多的文章可以满足你的兴趣，你最感兴趣的应是“主体树脂真的具有羟基，羧基或酰胺基团吗？”醇酸是由碱性的甘油或季戊四醇与二元酸如苯酐反应生成的盐或酯，作为涂料用，他们必须被干性或不干性油改性如蓖麻油或亚麻油。
醇酸树脂真的有我们所需要的官能团吗？是的，主要是羟基和少量的羧基。
醇酸实际上是聚酯，但聚酯通常没有醇酸那么复杂。
不象醇酸一般用三羟基醇和苯酐，聚酯常用二羟基醇和直链的二元酸，他们可以是也可以不是用油改性的。
例如，我公司的某些CYPLEX树脂就是二聚酸改性的。
聚酯一般主要是羟基型的，也有羧基型的，如CYPLEX1600就是高羧基官能团的聚酯树脂。
丙烯酸树脂是用含OH，COOH及CONH2官能团的单体加成聚合的。
有些丙烯酸树脂可能含有所有这些官能团，一般一种官能团的优先。
环氧树脂通常是含羟官能团的。
氨基树脂的官能团图示如下，CYMEL303的反应机理见单册，在这里只要说说某些反应产物足以说明了，除了交联就是甲醇，水和甲醛。
氨基树脂中的官能团：HYDROXY—OH羟基—COOH羧基—CONH2酰胺基注意，可能的反应从这开始：先羟甲基化然后烷氧基化CH2OH羟甲基CH2OR烷氧基=CH3甲基=C2H5乙基=C4H9丁基羟甲基化烷基醚化先是在碱或酸的存在下，甲醛的CH2OH（羟甲基）取代三聚氰氨上的H（氢），即羟甲基化反应，然后是在酸性条件下用醇进行烷氧基化反应，如果ROH上的R 是CH3，即甲氧甲基。
甲氧甲基三聚氰氨甲醛树脂的结构：部分烷氧基化的聚合体全部烷氧基化的单体全部烷氧基化的单体就是HMMM，或叫CYMEL303，所有的H（6个）都被甲氧甲基取代。
部分烷氧基化的聚合体树脂具有甲氧甲基，羟甲基和—NH亚胺基。

(16)Table of ContentsHighly Methylated Melamine ResinsHighly methylated melamine resins consist of commercial versions of hexamethoxymethylmelamine (HMMM). They differ primarily in their degree of alkylation and monomer content. All are efficient crosslinking agentsfor hydroxyl, carboxyl and amide functional polymers. The practical equivalent weight for most of the resins is 130-180. Advantages are low VOCs; high film flexibility and toughness when used with inherently flexible backbone resins; excellent formulation stability, especially in waterborne systems formulated at a pH of 8-9; good mar resistance; and good intercoat adhesion properties. As typical with melamine resins, all are low in color and color development, have excellent exterior durability and good heat resistance. Because of their high extent of alkylation, the resins in this series require the addition of a strong acid catalyst for acceptable cure response when bakedat 125-150°C. Typically, 0.2- 0.4% p-toluene sulfonic acid based on total binder solids is recommended. The optimum concentration of acid catalyst depends on the basicity of the other components in the formulation and should be determined experimentally. Using a blocking amine forthe acid catalyst and adding a stabilizing alcohol to the formulation can enhance formulation stability.High Solids Methylated Melamine Resins4Methylated High Imino Melamine ResinsMethylated high imino melamine resins are partially methylolated and highly alkylated. These characteristics result in resins containing a significant concentration of alkoxy/imino or high NH functionality. The advantagesare fast cure response at 120-150°C without the need for strong acid catalysts, fast cure response in waterborne formulations, high film hardness, and low formaldehyde release on cure. In addition to reacting with hydroxyl, carboxyl and amide functionality on polymers, these resins also self-condense readily. Therefore, their practical equivalent weight is typically 180-240. They too, can be stabilized by adding tertiary amine and stabilizing primary alcohol to the formulation. Compared to their highly alkylated counterparts, the imino resins usually result in slightly less flexible coatings and slightly higher VOCs when used in solvent-based systems.Partially Methylated Melamine ResinsPartially methylated melamine resins are highly methylolated and partially alkylated. They cure well at 125-150°C without the need to add a strong acid catalyst. The acidity of most polymers used in thermoset coatings is sufficient to catalyze their reaction. Their film performance properties are similar to those of the high imino resinsin the previous category. In addition to reacting with the hydroxyl, carboxyl and amide functionality of polymers they, too, can self-condense readily. Their practical equivalent weight is also 180-240. As with all melamine resins, they can be stabilized by adding amine and stabilizing alcohol to the formulation. The major limitation of these products is high formaldehyde release on baking, primarily due to their high free methylol content.Product availability can vary by usage location. Please contact your local Allnex representative regarding availability in specific countries and regions.5Highly Alkylated Melamine ResinsThe highly alkylated melamine resins in thiscategory are similar to the commercial versions of hexamethoxymethylmelamine (HMMM) except for the type of alkylation alcohol. The resins contain combinations of methoxy sites and longer chain length alkoxy sites (ethoxy, n-butoxy or iso-butoxy). They also differ from each other in their degree of alkylation and monomer content. Longer chain length alkoxy sites impart lower viscosity, improved flow and leveling, and intercoat adhesion. All of the resins in the series are efficient crosslinking agents for hydroxyl, carboxyl and amide functional polymers. The practical equivalent weight for most is 140-200. Other advantages are low VOCs; high film flexibility and toughness when used with inherently flexible backbone resins; excellent formulation stability, especially in waterborne systems at a pH of 8-9 and good mar resistance properties. Because of their high extent of alkylation, the resins in this series require the addition of a strong acid catalyst for acceptable cure response when baked at 125-150°C. Typically, 0.2-0.4% p-toluene sulfonic acid based on total binder solids is recommended. The optimum concentration of acid catalyst depends on the basicity of the other components in the formulation and should be determined experimentally. The use of a blocking amine for the acid catalyst and the addition of a stabilizing alcohol to the formulation should enhance formulation stability.High Solids Mixed Ether Melamine Resins6High Imino Melamine ResinsThe high imino melamine resins in this category are similar to those in the high imino methylated melamine series in that they are partially methylated and highly alkylated. They differ from methylated melamine resins in the type of alkylation alcohol, and they contain combinationsof methoxy sites and n-butoxy sites. The butoxy sites impart improved flow and leveling and intercoat adhesion properties. As in the methylated series, their composition contains primarily alkoxy/imino or alkoxy/NH functionality. The advantages are fast cure response at 120-150°C without the need for strong acid catalyst addition; fast cure response in waterborne formulations; high film hardness; and low formaldehyde release on cure. In addition to reacting with hydroxyl, carboxyl and amide functional polymers, the resins also self-condense readily. Therefore, their practical equivalent weight is typically 200-250. They, too, can be stabilized by amine and stabilizing alcohol addition to the formulation.Product availability can vary by usage location. Please contact your local Allnex representative regarding availability in specific countries and regions.7n-Butylated Melamine Resinsn-butylated resins in this category are very polymeric in nature. They differ in extent of methylolation, butylation and polymerization. In general, higher extents of methylolation and butylation result in more hydrophobic resins with lower viscosities, higher stability, slightly higher film flexibility, film gloss and adhesion but slower cure response. Higher extents of polymerization result in faster film property development but also in higher viscosities, and therefore higher VOCs. None of the resins in this category require the addition of a strong acid catalyst for adequate cure at 125-150°C. Usually, the acidity of the other resin components in the formulation results in sufficient catalysis. In addition to reacting with hydroxyl, carboxyl and amide functionalities on polymers, these resinsself-condense readily. Their practical equivalent weight is typically 220-280 on a solids basis, High concentrations of the melamine resins in the formulation result in high film hardness and improved exterior durability but, possibly, lower film flexibility and lower adhesion properties. They, too, can be stabilized by adding amines and stabilizing alcohol to the formulation.Highly n-Butylated Melamine ResinsHighly butylated melamine resins are similar to the commercial versions of hexamethoxymethylmelamine (HMMM), except they are n-butylated. They also are slightly more oligomeric than their methylated counterparts.The butylation or butoxy sites impart improved flow and leveling and intercoat adhesion properties. However,cure response is slower than that of the resins in the methylated category. Yet, highly butylated melamine resins, are efficient crosslinking agents for hydroxyl, carboxyl and amide functional polymers. The practical equivalent weight is 160-220. Other advantages are high film flexibility and toughness when used with inherently flexible backbone resins; excellent formulation stability; and good mar resistance properties. Because of their high extent of alkylation, the resins require the addition of a strong acid catalyst for acceptable cure response when baked at 125-150°C. Typically 0.2-0.4% p-toluene sulfonic acid based on total binder solids is necessary. The optimum concentration of acid catalyst depends on the basicity of the other components in the formulation and should be determined experimentally. The use of a blocking amine for the acid catalyst and the addition of a stabilizing alcohol to the formulation should enhance formulation stability.Butylated Melamine Resins(1) = Foil solids 45 min at 45°C (2) = Pan solids 60 min at 100°C (3) = Pan solids 120 min at 105°C (4) = Pan solids 120 min at 120°C8n-Butylated High Imino Melamine ResinsButylated high imino melamine resins are similar to those in the high imino methylated melamine series; they are partially methylolated and highly alkylated. They differ from the high imino methylated melamine resins in that they are n-butylated. The butoxy sites impart improved flow and leveling and intercoat adhesion properties.As in the methylated series, their composition contains primarily alkoxy/imino or alkoxy/NH functionality. The advantages are fast cure response at 120- 150°C without the need to add a strong acid catalyst; high film hardness; and low formaldehyde release on cure. In addition to reacting with hydroxyl, carboxyl and amide functionality on polymers, the resins self-condense readily. Therefore, their practical equivalent weight is typically 160-220. They can be stabilized by the addition of an amine and a stabilizing alcohol to the formulation. iso-Butylated Melamine ResinsThe iso-butylated melamine resins in this category are similar to polymeric n-butylated resins and differ only in that they are "iso" rather than "n"-butylated. It is generally believed that iso-butylated melamine resins cure faster than n-butylated resins, although differences in extentof methylolation, alkylation and polymerization are believed to be more significant factors with respect to cure response. The comments made previously concerning the n-butylated resins also apply to the iso-butylated resins.Product availability can vary by usage location. Please contact your local Allnex representative regarding availability in specific countries and regions.910Methylated ResinsMethylated urea resins were designed for waterborne and solvent-based formulations for interior and non-UV resistant applications. They differ from each otherprimarily in their extent of methylolation and methylation. As with other amino resins for coatings, higher extents of alkylation result in improved compatibility with most binders, improved stability; and better flow and leveling, but slower cure response. None of these resins require the addition of a strong acid catalyst for acceptable cure response at 125°C. The acidity of the other components in a formulation usually is sufficient for catalysis. For very low temperature cure systems, those for wood finishes, for example, a 2-component formulation is necessary. In such formulations, the acid catalyst is added to the fully-formulated system just prior to use. If the bake temperature is around 70°C, a concentration of 1-2% on total binder solids of a strong or weak acid is recommended. In general, urea resins react with thehydroxyl, carboxyl and amide functional sites on polymers, but they also have a high tendency for self-condensation. Their practical equivalent weight is in the range of 180- 260. The use of a blocking amine for the acid catalyst and the addition of a stabilizing alcohol to the formulation enhances formulation stability. The latter approach is recommended for 2-component formulations.Butylated resinsThe one resin in this category, CYMEL U-80 resin, issimilar in composition to several of the methylated resins, except that its alkylation alcohol is n-butanol. This resin is also recommended for interior and non-UV resistant coatings; it is used primarily in solvent-based systems. It is very hydrophobic and stable but slower curing than its methylated counterparts. A strong acid catalyst is recommended for acceptable cure response at 125°C. Other formulation details are the same as those given for methylated resins.High Solids Urea ResinsHigh Solids Urea ResinsProduct availability can vary by usage location.

They differ in extent of methylolation, butylation, and polymerization. In general, higher extents of methylolation and butylation result in more hydrophobic resins with lower viscosities, higher stability, and slightly higher film toughness, film gloss and adhesion but slower cure response. Higher extents of polymerization result in faster film property development but also in higher viscosities and, therefore, higher VOCs. None of the resins require the addition of a strong acid catalyst for adequate cure at 125°C. Usually, the acidity of the other resin components in the formulation is sufficient for catalysis. In addition to reacting with hydroxyl, carboxyl and amide functional polymers, the resins also selfcondense readily. Their practical equivalent weight is typically 220-300 on a solids basis. High concentrations of the urea resins in the formulation result inhigh film hardness, but, possibly, lower film toughness and lower adhesion properties. They can be stabilized by amine and stabilizing alcohol addition to the formulation. As with other urea resins,they are recommended for interior, non-UV resistant applications. The most typical applications are interior container coatings andButylated Urea Resins(1) = Pan solids 90 min at 105°C (2) = Pan solids 120 min at 105°C (3) = Pan solids 120 min at 120°C(4) = Pan solids 60 min at 100°C122-component solvent-based wood finishes, In the latter application, the acid catalyst is added to the fully-formulated system just prior to use. A concentration of 1-2% on total binder solids of a strongor weak acid is recommended for systems that require low bake temperatures - typically less than 70°C.iso-Butylated Urea ResinsThe iso-butylated urea resins in this category are similar tothe polymeric n-butylated resins, except that they are iso-butylated rather than n-butylated. It is generally believed that iso-butylated urea resins cure faster than n-butylated resins, although differences in extent of methylolation, alkylation and polymerization are believed to be more significant factors with respect to cure response. iso-butylated urea resins performin much the same way as n-butylated urea resins. That is, high concentrations of these resins in the formulation result in high film hardness, but, possibly, lower film toughness and lower adhesion properties. iso-butylated resins can be stabilized by adding amine and stabilizing alcohol to the formulation. They are recommended for interior and non·UV resistant applications, as well.Product availability can vary by usage location. Please contact your local Allnex representative regarding availability in specific countries and regions.1314Benzoguanamlne ResinsBenzoguanamine resins are similar to melamine-based resins in that they, too, are triazine based, but in this instance, the triazine has a benzene group substitution. Therefore, they are less functional than melamine-based resins, and are not UV resistant. Benzoguanamine resins are noted for their enhanced film flexibility, or toughness, and for their chemical resistance. They are typically used in primers, container coatings, and appliance finishes. Usually, highly alkylated, monomeric benzoguanamine resins result in higher film flexibility than that which can be achieved with other types of resins, but they alsorequire the addition of a strong acid catalyst for adequate cure at temperatures greater than 125°C. Their practical equivalent weights are slightly higher than the practicalweights of their melamine counterparts and range from 160-220. The less alkylated polymeric resins only require the acidity of the other components in the formulation to cure adequately at greater than 125°C, but they have higher VOCs in a solvent-based formulation. Their practical equivalent weights are also slightly higher than those of their melamine counterparts and range from 200-260 on a solids basis. The use of a blocking amine and the addition of a stabilizing alcohol to the formulation should enhance formulation stability.(1) = Pan solids 120 min at 120°CBenzoguanamine and Glycoluril Resins(2) = Foil solids 45 min at 45°C(3) = Pan solids 120 min at 105°CGlycoluril ResinsGlycoluril resins are similar to their melamine resinscounterparts in that they, too, are based on a ring structure,glycoluril. Similar to benzoguanamine resins, they areless functional than melamine resins but are UV resistantand can be used in exterior coatings. Their advantagesare film toughness and flexibility, ability to adhere tometals, and low formaldehyde release on curing. There aretwo categories in the product line, unalkylated methylolglycoluril resins, and those which are highly alkylated.CYMEL 1172 is unalkylated, and was designed for water-based coatings with low temperature cure performanceproperties. The highly alkylated resin, CYMEL 1170, wasdesigned to replace HMMM where there is a desire toimprove film flexibility. The same comments concerninghighly alkylated monomeric melamine resins also apply tothe alkylated glycoluril resins.Product availability can vary by usage location.

It can be used to crosslink hydroxy- and epoxy containing polymers to give highly durable, acid-resistant films that exhibit a favorable balance of hardness and flexibility. An important feature of CYMEL NF 2000is that it does not contain or emit formaldehyde on cure.It can be employed as the sole crosslinker in a coatingor ink formulation, or it may be used at lower levels in combination with other crosslinkers, such as conventional amino resins or isocyanates, in order to obtain a balance of properties. CYMEL NF 2000 is recommended for high quality durable finishes such as automotive topcoats, exterior can varnishes and coil coatings. CYMEL NF 2000 reacts with hydroxy functional backbone resins at >125°C bake schedules to form urethane linkages. Cure can typically be accomplished without use of a catalyst to yield films that exhibit excellent hardness, chemical resistance, exterior durability and environmental etch resistance. Addition of low levels of acid catalyst (e.g. 0.5% dodecyl benzene sulfonic acid on binder solids) has been found to improve humidity resistance properties in some systems. Both catalyzed and uncatalyzed formulations show good 1K package stability at 23°C. CYMEL NF 2000 will react with carboxy functional backbone resins, but require bake temperatures >150°C. CYMEL NF 3041CYMEL NF 3041 is a partially n-butylated crosslinker agent designed for 2 pack ambient and heat cured formulations for industrial wood and plastic applications. These systems have excellent early hardness, resistance properties, appearance and hot/cold cycle flexibility. CYMEL NF 3041 is a very effective crosslinking agent for alkyd, polyester and acrylic polymers containing primary hydroxyl functionality. CYMEL NF 3041 resin requires the addition of an acid catalyst to the formulation in order to obtain effective cure for both ambient and heat cured applications. It is recommended to use 2.0% CYCAT 500 based on weightof total binder solids. However, the acidity of other formulation components may affect the reaction rate and should be evaluated in combination with the catalyst. Catalyzed potlife can be extended by the addition of 10 to 20% primary alcohol on total binder solids. Methanol or ethanol is preferred to ensure early hardness development and sandability. The coatings demonstrate very good flow, gloss, early film hardness, early print resistance and chemical resistance.Formaldehyde Free Resins(1) = Foil solids 45 min at 45°C(2) = Pan solids 120 min at 105°C16Product availability can vary by usage location.
