用途
Apoplications
这类促进剂的促进效力低且抗烧焦性能差,故对二烯类橡胶已很少使用,但在特殊情况下,如用秋兰姆硫化物等硫黄给予体硫化时,本品具有活性剂的作用。硫脲类促进剂对氯丁胶的硫化却具独特的效能,可制得抗张强度、硬度、压缩永久变形等性能良好的氯丁硫化胶。本品与 NA-22相比,焦烧及硫化均快,但硫化平坦性较好。易分散、不喷霜。用量较大时,可进行高温高速硫化,特别适用于压出制品的连续硫化。本品也是丁基胶用促进剂,三元乙丙胶的硫化活性剂。对于天 然胶、氯丁胶、丁腈胶和丁苯胶有抗氧化作用。一般用作制造工业制品。特种电线、海绵制品等。
It is also a promoter of butyl adhesive and a vulcanizing active agent of ethylene-propylene diene(EPDM). For natural gum, neoprene gum, nitrile gum and butadiene gum have antioxidant effect.Generally used for manufacturing industrial products, special wire, sponge products, etc.
