非公路赛地赛车轮胎胎面胶配方的研发

Development of Tread Compound Formula for Off-road Racing Tire

介绍适用于非公路赛地赛车轮胎胎面胶配方的研发。轮胎胎面胶配方使用合理的生胶体系(天然橡胶/顺丁橡胶/溶聚丁苯橡胶并用)和补强体系(大量白炭黑与少量炭黑并用),并填充大量环保芳烃油。选择硬度较低、耐热老化性能和抗湿滑性能较好、滚动阻力较低的试验胶料进行轮胎生产,与竞品轮胎相比,试验轮胎具有较好的高速性能、操控性和抓着性能,同时可节油5%以上。

The development of tread compound formula for off-road racing tire was introduced.The reasonable raw rubber system(blending of natural rubber/cis polybutadiene rubber/solution polymerized styrene butadiene rubber)and reinforcement system(blending of a large amount of silica and a small amount of carbon black)were used in the tire tread compound formula,and a large amount of environmentfriendly aromatic oil was filled.Compared with competing tires,the test tires produced by choosing test compounds with lower hardness,better heat aging resistance and wet skid resistance,and lower rolling resistance had better high-speed performance,handling and grip performance,and could save more than 5%fuel.
