橡胶工业中,过氧化物的应用越来越普遍,以便满足产品使用性能的需求,例如较好的耐热性和较低的压缩永久变形。使用过氧化物硫化的另一个原因是可消除不利的副产物,如亚硝胺。遗憾的是,过氧化物硫化胶料一般在力学性能方面逊于硫黄或硫黄给予体体系硫化的胶料。为了尽可能减小性能损失,必须采用聚合物和/或补强填料含量较高的配方;由此致使胶料的成本上升,解决的方法包括用滑石粉替代部分补强填料。
In the rubber industry, the use of peroxides is becoming more commonplace in order to meet the demands of product performance, such as better heat resistance and lower compression set. Another reason for using peroxide vulcanization is to eliminate adverse by-products such as nitrosamines. Unfortunately, peroxide vulcanizates are generally inferior to sulfur or sulfur in terms of mechanical properties to give system vulcanizates. In order to minimize performance losses, it is necessary to use formulations with higher polymer and / or reinforcing fillers; thereby increasing the cost of the compound, including replacing some of the reinforcing fillers with talc.
