丁基橡胶(IIR)和卤化丁基橡胶(HIIR)生产技术

TECHNOLOGY FOR THE PRODUCTION OF BUTYL RUBBER (IIR)

AND HALOBUTYL RUBBER (HIIR)

丁基橡胶（IIR）和卤化丁基橡胶（HIIR）生产技术

PROCESS FEATURES

Butyl rubber (IIR) is an elastomeric copolymer of isobutylene with small

amounts of isoprene, offered in a range of polymer grades.

Halogenating the isoprene groups in IIR produces a rubber which could co-cure with elastomers such as NR, BR and SBR while preserving the essential properties of IIR. The commercial halobutyl rubbers, bromobutyl (BIIR) and chlorobutyl (CIIR), are more easily vulcanized than IIR.

The major application area is the tire industry, mainly, as IIR, for innertubes and tire curing bladders and, as HIIR, for inner liners.

The CONSER process, developed with the support of consultants and specialists having experience in production of butyl rubber, belongs to the well established slurry polymerization process, practiced by the leading world producers of butyl rubber. CONSER can offer a technology for the production of butyl rubber (IIR) and halo-butyl rubber (HIIR ) fully competitive as consumption of raw materials, utilities and chemicals and as quality of the products.

工艺特点

丁基橡胶（IIR）是一种异丁烯和少量异戊二烯的弹性体共聚物，产品为聚合级。IIR中

异戊二烯基的卤代能够产生一种可以与NR、BR、SBR等弹性体一同硫化的橡胶而同时保留IIR的特性。工业品卤化丁基橡胶、溴化丁基橡胶（BIIR）和氯化丁基橡胶（CIIR）比普通丁基（IIR）更易硫化。

主要的应用领域为轮胎工业，作为IIR主要用于生产内胎以及轮胎硫化胶囊，HIIR用于

内衬。在众多拥有生产丁基橡胶的俄顾问和专家的帮助下，CONSER工艺属于浆料聚合工

艺，该工艺由世界领先的丁基橡胶的生产商应用并验证。

CONSER的丁基橡胶（IIR）和卤化丁基橡胶（HIIR）的生产技术在原料消耗、公用工程消耗和化学品消耗以及产品质量上都具有极具竞争性。

PROCESS DESCRIPTION

工艺描述

IIR PROCESS

The butyl rubber technology offered by CONSER is based on the following main steps:

Polymerization

Recycle compression and purification

Finishing

IIR工艺

由CONSER提供的丁基橡胶技术主要包括如下步骤：

聚合

循环压缩和提纯

精整

Polymerization

The butyl rubber is produced by co-polymerizing isobutylene with a small amount of isoprene, in a solution with methyl chloride, at low temperature (close to –100°C) and with aluminium chlorides as catalyst. In the flash vessel water replaces the organic solvent, thus producing a water slurry.

聚合

通过异丙烯与少量异戊二烯的共聚在氯甲烷的溶液中用氯化铝作为催化剂在低温（接近零下100度）的条件下通过共聚反应生成丁基橡胶。在闪蒸容器中用水代替有机溶剂生产出水淤泥。

Recycle compression and purification

Unreacted monomers and solvent are flashed, compressed, dried and fractionated in a sequence of distillation columns to recover solvent and isobutylene, both recycled to the polymerization section, while all the impurities are purged out.

循环压缩和精制

未反应的单体和溶剂被闪蒸、压缩、干燥并在一系列的蒸馏塔中进行分馏来回收溶剂及异丁烯，两者都被循环到聚合部分，所有的杂质被分离出来。

Finishing

The water polymer slurry from the reaction section is sent directly to the finishing, where it is dried, pressed, baled and packaged.

精整

反应部分的水性料浆被直接送至精整部分进行干燥、加压、打包并包装。

HIIR PROCESS

Part of the water polymer slurry from the polymerization is fed to the halogenation section:

here the water is replaced with hexane to produce a polymer solution which is fed first to the halogenation reactors and then to the neutralization system.

The hexane is finally removed and replaced again with water. The water slurry is dried, pressed, baled and packaged in a second finishing line.

IIR工艺

部分来自聚合工段的水性料浆被送入卤化部分，在该部分用正己烷代替水生产聚合物溶液，首先送入卤化反应器然后送入中和系统。最终己烷被去掉并再次用水替换。然后在第二条精整线上将水料浆干燥、加压、打包并包装。
