Description
技术领域
本发明涉及一种不粘模的高性能丁腈橡胶胶料及其制备方法。
背景技术
丁腈橡胶主要用于制作耐油制品,如耐油管、胶带、橡胶隔膜和大型油囊,常用于制作各类耐油模压制品,如O形圈、油封、皮碗、膜片、活门、波纹管等,也用于制作胶板和耐磨零件,在汽车、航空、石油、复印等行业中成为必不可少的弹性橡胶,混炼胶实在丁腈橡胶的基础上,加上硫化剂、促进剂等化学物,使丁腈橡胶可以直接用于生产模压制品。其缺点是胶料弹性较差,直接用于生产压膜制品时,易粘模具,不易脱模并产生雾气,令产品表面泛白,各项性能大幅降低。

二辛脂 5.31;
氧化锌 2.52;
硬脂酸 1;
2,2,4-三甲基-1 0.5;
N-环己基-N'-苯基对苯二胺 0.5;
二硫化四甲基 0.76;
N-环己基-2-苯并噻唑次磺酰胺 0.91;
2,2'-二硫代二苯并噻唑 0.71;
硫磺 0.25。
本发明的不粘模的高性能丁腈橡胶胶料的制备方法,包括以下步骤:
1)将以下重量百分比的原料搅拌均匀:丁腈橡胶50.4,碳黑N33910.61,碳黑N65018.59,微细碳酸钙 7.96,二辛脂5.31,氧化锌2.52,硬脂酸1,2,2,4-三甲基-10.5,N-环己基-N'-苯基对苯二胺0.5,二硫化四甲基0.76,N-环己基-2-苯并噻唑次磺酰胺0.91,2,2'-二硫代二苯并噻唑0.71,硫磺0.25;配比成半成品混炼胶;
2)将半成品混炼胶投入密炼机,温度不超过90℃;
3)将经过步骤2)处理后的半成品混炼胶投入开炼机,温度不超过55℃;
4)将经过步骤3)处理后的半成品混炼胶停放24小时;
5)将经过步骤4)处理后的半成品混炼胶投入小开炼机进行反炼;
6)将经过步骤5)处理后的半成品混炼胶进行打三角包;之后根据产品要求出片。
与现有技术相比本发明的有益效果为:本发明的不粘模的高性能丁腈橡胶胶料具有很好的耐油、耐热、抗拉、耐磨性能,弹性极好,不易扯断,在用于生产压膜制品时不产生雾气,容易脱模,而且制备方法简单,适宜大范围推广应用。
