摘　　要：研究了硫化剂ＴＣＹ对丙烯酸酯橡胶（ＡＣＭ）的硫化特性。通过改变硫化温度，分析了硫化反应活化能，并研究了硫化剂及助硫化剂在不同用量下的硫化特性和硫化胶性能。试验结果表明，硫化剂ＴＣＹ对活性氯型ＡＣＭ具有低温快速硫化能力，其硫化反应活化能为６０５２ｋＪ·ｍｏｌ－１；添加少量硫黄作为ＡＣＭ的助硫化剂，可有效提高胶料的硫化速度和交联度。The vulcanization behavior of acrylate rubber(ACM) cured with trithiocyanuric acid(TCY) was investigated.The activation energy for vulcanization was analysed at different curing temperature,and the vulcanization behavior and the vulcanizate properties were investigated by using different curative and secondary curative levels.The test results showed that TCY was a fast curative at low temperature for ACM with active chlorine and its activation energy for vulcanizationwasabout 60.52 kJmol-1;the comprehensive properties of vulcanizate were obtained by adding small amount of sulfur to ACM compound as secondary curative to increase curing rate and crosslinking density.
