(T-4)-双(1-呱啶二硫代羧酸-S,S’)-锌

(T-4)-双(1-呱啶二硫代羧酸-S,S’)-锌用途

用作天然橡胶、丁苯橡胶及胶乳的促进剂。硫化临界温度低，故混炼时需特别注意焦烧。硫化温度高于121℃时硫化平坦性急剧变窄。硫化速度较秋兰姆促进剂快，适于快速加压硫化，也适于热空气硫化和水不溶性促进剂的胶乳硫化。本品需配以氧化锌。除单独使用外，也可用作噻唑类促进剂的第二促进剂。本品无污染，硫化胶无臭、无味。主要用作制造胶乳制品、胶布、胶鞋等自硫胶浆。一般用量为0.15~1份。

(T-4)-双(1-呱啶二硫代羧酸-S,S’)-锌制备

（1）五亚甲基二硫代氨基甲酸锌的制备将六氢吡啶、二硫化碳和氢氧化钠溶液加入反应釜，搅拌下控制反应温度(18±3)℃，进行缩合反应。当反应体系的pH值不再变化，即为缩合反应终点。反应产物为N-五亚甲基二硫代氨基甲酸钠。

（2）促进剂ZPD的制备在上述制得的N五亚甲基二硫代氨基甲酸钠中加入氯化锌水溶液，搅拌下控制温度(18±3)℃，进行复分解反应。反应产物经水洗、过滤、干燥、粉碎、过筛，即得成品。
