短钢丝纤维对轮胎胎面性能的影响及强化机理研究

以短钢丝纤维作为补强体，通过短钢丝纤维表面镀铜-镀锌处理，设计了短钢丝纤维补强轮胎胎面的配方体系、共混及制备工艺。试验结果表明，当5 mm短钢丝纤维的质量分数在0.10左右时，其补强效果较为理想。构建了短钢丝纤维4种分散情况下的胎面胶复合强化模型，并在此基础上分析了短钢丝纤维与胎面胶的复合强化机理，有效实现了短钢丝纤维与胎面胶的粘合，复合体综合性能表现良好。;The tread compound formula system and process with short steel fiber as reinforcement were designed and the fiber surface was treated with copper-zinc plating.The results showed that，the reinforcement effect was good when the mass fraction of 5 mm short steel fiber was about 0.10.The tread compound reinforcement model was constructed considering four kinds of short steel fiber distribution circumstances，and the composite reinforcement mechanism was analyzed based on this model.It was found that good adhesion between short steel fiber and tread compound was obtained and the comprehensive properties of the composites were good
