使用自制交联剂2-二正丁基胺基4,6-二硫醇均三嗪(DB)制备了热塑性弹性体PVC/CR,并对用DB交联PVC、CR共聚物的交联特性、橡塑比、交联剂用量对材料的性能影响进行了考察,结果表明:由于共交联剂DB能使PVC与CR产生共交联作用,改善了两者的相容性,可以制备性能良好的PVC/CR-TPE。最优橡塑比PVC/CR以25/75左右为宜,交联剂用量以2~3份为宜。
The thermoplastic elastomer PVC / CR was prepared by using 2-di-n-butylamine-based 4,6-dithiol s-triazine (DB) , Rubber ratio, the amount of crosslinking agent on the performance of the material were investigated, the results showed that: due to co-crosslinking agent DB can produce PVC and CR co-crosslinking effect, improve the compatibility between the two, you can prepare the performance Good PVC / CR-TPE. Optimal rubber than PVC / CR about 25/75 is appropriate, the amount of crosslinking agent to 2 to 3 copies is appropriate.
