摘　　要：研究多功能交联剂WY988对跑气保用轮胎支撑胶性能的影响。结果表明:在支撑胶配方中加入多功能交联剂WY988,胶料的抗硫化返原性能提高,硫化胶的硬度和定伸应力增大,耐屈挠性能不变,损耗因子减小;上下模支撑胶的硬度之差减小,成品轮胎的耐久性能提高。The effect of multifunctional crosslinking agent WY988 on the properties of support compound for run-flat tire was studied. The results showed that by adding WY988 in the support compound formula,the anti-reversion property of the compound was improved,the hardness and modulus of the vulcanizate increased,the flexure resistance was kept unchanged,and loss factor decreased. The hardness difference between the upper and lower dies of support compound was reduced,and the durability of the finished tire was improved.
