| 中文摘要: |
| 研究多功能交联剂WY988在输送带覆盖胶中的应用。结果表明：在天然橡胶（NR）胶料和NR/顺丁橡胶（BR）并用胶中添加多功能交联剂WY988，并减小促进剂和硫黄用量，可以达到等效的硫化促进效果；多功能交联剂WY988与炭黑N234配合使用的胶料耐磨性能与炭黑N115/N234并用的胶料相近；添加多功能交联剂WY988的NR胶料和NR/BR并用胶耐老化性能提高；NR胶料的多功能交联剂WY988硫化体系优化配合为多功能交联剂WY988 0.6，硫黄 0.26，促进剂 0.4，硫化剂DTDM 2；NR/BR并用胶的多功能交联剂WY988硫化体系优化配合为多功能交联剂WY988 0.6，硫黄 0.26，促进剂 0.8，硫化剂DTDM 1.6。 |
| 英文摘要: |
| The application of multifunctional crosslinking agent WY988 in the cover compound of conveyor belt was studied. The results showed that the addition of multifunctional crosslinking agent WY988 in NR compound and NR/BR compound could reduce the amount of accelerator and sulfur，and still achieve the equivalent accelerating vulcanization result. With combination of multifunctional crosslinking agent WY988 and carbon black N234，the abrasion resistance of the compound reached the similar level of carbon black N115/N234 filled compound. The aging resistance of NR and NR/BR compound was improved with the addition of multifunctional crosslinking agent WY988. The optimized multifunctional crosslinking agent WY988 vulcanization system for NR compound was as follows：multifunctional crosslinking agent WY988 0. 6，sulfur 0. 26，accelerator 0. 4，vulcanizing agent DTDM 2. For NR/BR blend，the optimized formulation was as follows：multifunctional crosslinking agent WY988 0. 6，sulfur 0. 26，accelerator 0. 8， vulcanizing agent DTDM 1. 6. |
