摘　　要：通过设计相同硬度、不同玻璃化转变温度(T_(g))的胎面胶配方,研究胎面胶在不同季节测试对轮胎抗湿滑性能的影响。结果表明:在胎面胶T_(g)为-30~-8℃范围内,随着T_(g)的降低,轮胎的平均峰值制动因数和抗湿滑性能指数减小;环境温度较低对轮胎抗湿滑性能的测试更有利;高T_(g)的白炭黑配方对测试环境的依赖性较小,排水性能好的花纹结构可以有效提高轮胎的抗湿滑性能;以白炭黑填充体系为主的胎面胶相比炭黑填充体系更有利于轮胎抗湿滑性能的提高。By designing tread compound formulations with the same hardness but different glass transition temperatures(T_(g)),the effect of tread compound on the wet skid resistance of tires in different seasons was studied.The results showed that within the range of T_(g)of tread compound from-30 to-8℃,as T_(g)decreased,the average peak braking factor and wet skid resistance index of the tire decreased.A lower ambient temperature was more favorable for testing the wet skid resistance of the tires.The silica formula with high T_(g) had less dependence on the testing environment,and the pattern structure with good drainage performance could effectively improve the wet skid resistance of the tires.The tread compound mainly filled with silica was more conducive to improving the wet skid resistance of the tires compared to the carbon black filling system.
