二丁基二硫代氨基甲酸锌(II)

二丁基二硫代氨基甲酸锌(II)用途

用作超速橡胶硫化促进剂。硫化速度快，可在低温下硫化，但易烧焦。单用本品时活性不如促进剂PZ，与二硫代氨基甲酸铵相比，活性更差。胶料在120～135℃时硫化速度很快，硫化温度升高，硫化平流性变差。用作硫化促进剂时，需用氧化锌活化；是咪唑类、次磺酰胺类促进剂的良好活化剂；对含促进剂M、TMTD或M和TMTD混用的丁基橡胶，有很强的活化作用，可加速缩短其硫化时间；本品宜用于白色、艳色和透明制品；还可用于杀菌剂，制造胶乳制品，医疗制品，胶布和白硫制品等。在干胶胶料中通常用量为0.1～1份，在胶乳胶料中为0.5～1.0份。　　
是有效的过氧化物分解剂，常与主抗氧剂并用，用于聚丙烯、聚氯乙烯，也用作橡胶胶粘剂和乳胶固化促进剂
