促进剂DZ(DCBS)

促进剂DZ(DCBS)用途

【用途一】
用作天然胶、顺丁胶、丁苯胶、异戊胶的后效性促进剂
【用途二】
用于天然胶、顺丁胶、丁苯胺、异戊胶等的后效性促进剂。在橡胶中分散性能良好。在天然胶胶料中焦烧时间比促进剂DIBS更长，因此操作安全性更高。在硫化温度下硫化速度与促进剂DIBS相似。硫化平坦性与促进剂CZ相近。含该品的胶料用无模蒸气硫化要比平板硫化速度稍快一些。适于高活性补强剂用量较大胶料，亦适用于以聚丁二烯橡胶或再生胶为主的胶料。硫化胶机械性能，尤其是动态性能比较好，弹性和定伸强度高。因硫化胶有苦味，不适于制造与食物接触的橡胶制品。主要用于制造轮胎、胶带、减震制品和翻修轮胎的拴背胶料等。一般用量为0.5-1份，硫黄为2.5份左右。该品低毒。
