不同种类硫化促进剂应用于不同种类的橡胶体系中。在橡胶助剂类产品中,二乙基二硫代氨基甲酸碲(简称TDEC),主要用在下游密封件等行业中,尤其是用在高端制品上,是二硫代氨基甲酸碲盐促进剂的特殊品种,作为一种三元乙丙橡胶、天然橡胶和丁苯橡胶的超硫化促进剂。TDEC不仅可提高三元乙丙橡胶的硫化效果,降低能耗,还可以提高制品的发泡均匀性和机械强度。因此,TDEC是三元乙丙橡胶中的重要助剂。目前,TDEC类促进剂的合成方法主要是通过可溶性盐与二乙基二硫代氨基甲酸钠(简称DDTC)反 Different kinds of vulcanization accelerators are used in different kinds of rubber systems. In the rubber chemicals, tellurium diethyldithiocarbamate (referred to as TDEC), mainly used in the downstream seals and other industries, especially for high-end products, is the dithiocarbamate tellurium salt accelerator Of the special varieties, as a kind of EPDM, natural rubber and SBR super-vulcanization accelerator. TDEC can not only improve the vulcanization of EPDM rubber, reduce energy consumption, but also can improve foam uniformity and mechanical strength of products. Therefore, TDEC is an important assistant in EPDM. At present, the synthesis method of TDEC accelerators is mainly through the combination of soluble salts and sodium diethyldithiocarbamate (DDTC)
