其他信息
- Alfa Aesar:N,N'-二乙基硫脲,98% N,N'-Diethylthiourea, 98%(105-55-5)
- 上游原料:二硫化碳
- Sigma Aldrich:105-55-5(sigmaaldrich)
- 海关编码:29309070
- 用途一:该品为硫脲类促进剂,这类促进剂一般是由胺二硫化碳反应得到的,最常用的品种是乙撑硫脲(NA-22)和N,N'-二正丁基硫脲(DBTU)等。这类促进剂的促进效力低且抗焦烧性能差,故对二烯类橡胶来说现已绝少使用,但在某些特殊情况下,如用秋兰母硫化物等硫黄给予体硫化剂时,它具有活性剂的作用。硫脲类促进剂对于氯丁胶的硫化却具有独特的效能,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。二乙基硫脲与NA-22相比,焦烧及硫化均快,但硫化平坦性较好。该品易分散,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。该品亦为丁基胶用促进剂,三元乙丙胶的硫化活性剂。在天然胶和丁苯胺中能活化噻唑类和次磺酰胺类促进剂,对天然胶、氯丁胶、丁腈胶和丁苯胶有抗氧化作用。二乙基硫脲还用于配制缓蚀剂Rodine 31A
- 方法一:由乙胺与二硫化碳反应而得。
