摘　　要：研究抗硫化返原剂WY808,WK901,WY9188,HT-K在全天然橡胶体系配方中的应用,对比其抗硫化返原效果。结果表明:在4种抗硫化返原剂中,抗硫化返原剂WY9188和WK901的抗硫化返原效果具有明显优势;抗硫化返原剂WY9188在硫化返原后期和整体阶段的抗硫化返原效果较好;抗硫化返原剂WK901在硫化返原前期的抗硫化返原效果优良;4种抗硫化返原剂均能改善过硫化状态硫化胶的物理性能;在0.5~1.5份用量范围内,抗硫化返原剂WK901的最佳用量为1.5份,抗硫化返原剂WY808的最佳用量为1份。抗硫化返原剂WK901,WY808,HT-K可以直接添加,不需要对原硫化体系进行调整。使用抗硫化返原剂WY9188时需要适当减小促进剂用量。The application of anti-reversion agent WY808,WK901,WY9188 and HT-K in the formulation of all natural rubber system was studied,and the anti-reversion properties were compared. The results showed that,among the four kinds of anti-reversion agent,WY9188 and WK901 had obvious advantages. WY9188 had better late-stage and overall anti-reversion effect,while WK901 had excellent early-stage anti-reversion effect. The physical properties of the overcured vulcanizates could be improved with any of the four kinds of anti-reversion agent. Within the dosage range of 0. 5 ~ 1. 5 phr,the optimum dosage of WK901 was 1. 5 phr,and that of WY808 was 1 phr. WK901,WY808,HT-K could be used directly without any adjustment on the original vulcanization system. It was necessary to reduce the dosage of accelerator with addition of WY9188.
