预分散橡胶助剂母粒研发进展

A brief overview on the technical progress of predispersed rubber chemicals masterbatch

概述了传统橡胶助剂产业现状及发展方向,指出传统橡胶助剂产品存在的问题及发展预分散橡胶助剂母粒产品的必要性;简要介绍了预分散橡胶助剂母粒的组成及其加工过程;重点关注在橡胶助剂母粒中起黏结和保护橡胶助剂等关键作用的橡胶载体,并具体分析了行业中广泛使用的具有良好极性兼容性的EPDM/EVA橡胶载体;概述了国内外预分散橡胶助剂母粒的现状及研究动向。目前,提高预分散橡胶助剂母粒在橡胶加工过程中促进助剂在胶料中均匀、快速、准确分散的能力,并且赋予预分散橡胶助剂母粒更强、更新的功能,是橡胶助剂母粒发展的主要趋势;同时应加快建立先进完善的预分散橡胶助剂母粒评价系统。

This review summarizes the production situation,the development trends and the issues of rubber chemicals industrial and the necessity of production of predispersed rubber chemicals masterbatch. The composition and fabrication process of predispersed rubber chemicals masterbatch is discussed. The rubber substrates of predispersed rubber chemicals masterbatch play an important role in the performance of rubber chemicals masterbatch in terms of coherence and protection of the inside rubber chemicals. The commonly used rubber substrate,EPDM/EVA,is analyzed with emphasis on its polar compatibility. The production situation and research trends of predispersed rubber chemicals masterbatch in China and abroad is briefly described and discussed and the main research trends will be the enhancement of the ability of predispersed rubber chemicals masterbatch by making the rubber chemicals dispersed more evenly,more rapidly and more accurately. And it is equally important to make predispersed rubber chemicals masterbatch of better quality and greater functionality. Meanwhile,a comprehensive evaluation system of predispersed rubber chemicals masterbatch should be established as soon as possible.
