摘要
研究噻二唑硫化体系(硫化剂PT75/促进剂903体系)对氯化聚乙烯橡胶(CM)性能的影响。结果表明:与过氧化物硫化体系(过氧化物BIPB/助交联剂TAIC体系)胶料相比,噻二唑硫化体系胶料的拉伸性能和抗撕裂性能大大改善,耐热老化性能相当,耐油性能较好;硫化剂PT75和促进剂903用量比为2/2时,胶料的压缩永久变形较小,拉伸性能和抗撕裂性能较好,耐热老化性能优异。
The inlfuence of thiadiazole curing system （vulcanizing agent PT75 and accelerator 903） on the properties of CM was investigated. The results showed that, compared with the peroxide curing system （peroxide BIPB and co-agent TAIC）, by using the thiadiazole curing system, the tensile properties and tear resistance of CM vulcanizates were greatly improved, the heat aging resistance was similar, and the oil resistance was better. It was found that when the addition levels of PT75 and accelerator 903 were 2 and 2 phr, respectively, the compression set of the CM vulcanizates was very low, the tensile properties and tear resistance were good, and heat aging resistance was excellent.
