| 中文摘要: |
| 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。 |
| 英文摘要: |
| The application of anti-reversion agent WY808，WK901，WY9188 and HT-K in formulation of all natural rubber system was studied，and the anti-reversion property were compared.The results showed that，among the four kinds of anti-reversion agent，WY9188 and WK901 had obvious advantages.WY9188 had better lately and overall anti-reversion effect，while WK901 had excellent early anti-reversion effect.The physical properties of vulcanizates in over-vulcanization state could be improved by 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 adjusting the original vulcanization system.It was necessary to reduce the dosage of accelerator in the use of WY9188. |
