Preparation method and application of benzyl-containing zinc aminothioformate series vulcanization accelerator

The invention relates to a preparation method and application of a benzyl-containing zinc aminothioformate series vulcanization accelerator. The preparation method comprises the following steps: firstly, uniformly mixing water, benzyl secondary amine, zinc oxide and a surfactant, then adding carbon disulfide into the mixed solution to react, and finally filtering and drying the reactant to obtain the benzyl-containing zinc aminothioformate series compound. The compound can replace zinc diethyldithiocarbamate and zinc di-n-butyl dithiocarbamate in rubber application, can reduce the generation of nitrosamine substances harmful to human bodies in the rubber product processing process, is a green rubber auxiliary, and has wide application prospects in the rubber industry. 本发明涉及含苄基的氨基硫代甲酸锌盐系列硫化促进剂的制备方法与应用。首先将水、苄基二级胺、氧化锌、表面活性剂混合均匀，然后向上述混合液中加入二硫化碳反应，最后将反应物过滤、干燥，即得所述含苄基的氨基硫代甲酸锌盐系列化合物。该类化合物能在橡胶应用中代替二乙基二硫代氨基甲酸锌、二正丁基二硫代氨基甲酸锌，可减少在橡胶制品加工过程中对人体有害的亚硝胺类物质产生，是一种绿色橡胶助剂，在橡胶工业中应用前景广泛。
