中国国际橡胶技术展浅析：丁基橡胶

伴随着国际橡胶工业的高速增长，中国国际橡胶技术展现已汇集展商700余家，展览面积达50,000平方米，展商来自世界近30个国家和地区，集橡胶机械设备、橡胶化学品、橡胶原材料、轮胎和非轮胎橡胶制品、橡胶循环利用为一体，是橡胶行业相关企业各个环节操作者的年度盛会。今天就由中国国际橡胶技术展小编给大家详细介绍：丁基橡胶。

丁基橡胶(IIR)是由异丁烯和(少量)异戊二烯合成的共聚物。由于其分子主链上有密集的侧甲基分布和较少的双键，其结构特点决定了它不仅气密性好，透气率低，而且还具有耐热、耐老化、耐酸碱、耐臭氧、耐溶剂、电绝缘、减震及低吸水等性能特点。因此，IIR是制造轮胎内胎和硫化胶囊不可替代的材料。IIR虽有以上优良性能，但却破相粘接性差、硫化速度慢和难与其他橡胶难于共混的缺点，限制了它的应用领域。卤化丁基橡胶(HIIR)是IIR卤化(加氯或加溴)改性后的产品，主要有氯化丁基橡胶(CIIR)和溴化丁基橡胶(BIIR)两种，HIIR不仅保持了IIR优良的气密性特性，而且还克服了IIR硫化速度慢，与其他胶种相容性差等缺点，主要用于轮胎气密层和医用瓶塞等领域。

看完了以上的内容，想必您一定很想去了解更多这方面的内容吧？请移步到中国国际橡胶技术展，2021年10月20-22日即将在国家会展中心（上海）开展，更多精彩的资讯等你来看！中国国际橡胶技术展期待您的到来。
