目前在橡胶生产过程当中,广泛采用氧化锌作硫磺硫化系统的活性剂。氧化锌显示出诸多优越性,最主要的是氧化锌能够提升硫化橡胶的弹性和强度。然而氧化锌在生产和废品处理过程当中,会对周围环境造成污染,危害人体健康。介绍了俄罗斯专家找到的一种可以替代氧化锌的环保新材料——次石墨,并介绍了对次石墨进行的多项研究试验,列举大量试验数据说明在丁苯橡胶硫化过程中,加入次石墨可增加其化学交联网密度,其力学性能与含氧化锌的硫化胶相差无几,某些指标甚至高于含氧化锌的硫化胶。
Currently in the rubber production process, the widespread use of zinc oxide as sulfur curing system active agent. Zinc oxide shows many advantages, the most important is that zinc oxide can improve the elasticity and strength of vulcanized rubber. However, during the process of production and waste treatment, zinc oxide can pollute the surrounding environment and endanger human health. Introduced a Russian experts to find a new environmentally friendly alternative to zinc oxide material - graphite, and introduced a number of sub-graphite research conducted, a large number of test data illustrate the process of SBR vulcanization, the addition of sub-graphite Can increase its chemical cross-linked network density, its mechanical properties and zinc oxide-containing vulcanizates are almost the same, some indicators even higher than the vulcanizate containing zinc oxide.
