摘　　要：研究了在天然橡胶中二乙基二硫代氨基甲酸镧、二正辛基二硫代氨基甲酸镧、甘氨酸二硫代氨基甲酸合钴镧、甘氨酸二硫代氨基甲酸合钴钇等稀土类配合物作为硫化促进剂的效果,并与传统促进剂M和二正辛基二硫代氨基甲酸钾进行了比较。结果表明,二乙基二硫代氨基甲酸镧和二正辛基二硫代氨基甲酸镧作为促进剂在天然橡胶中的硫化性能均优于促进剂M的。The vulcanizing properties of natural rubber by using lanthanum die th yldithiocarbamate,lanthanum dioctyldithiocarbamate,cobaltic yttrium glycinemetha ne dithioate and cobaltic lanthanum glycinemethane dithioate as vulcanizing acce lerators were first time studied.Compared with accelerator M and kalium diocthyl dithiocarbamate,the results showed the vulcanizing properties and mechanical pro perties of natural rubber accelerated by the rare earth complexes were better th an those by accelerator M.
