农业轮胎胎面胶的配方优化

对农业轮胎胎面胶的配方进行优化。结果表明,在农业轮胎胎面胶配方中适当增大顺丁橡胶用量、减小丁苯橡胶用量,以双峰防护蜡等量替代单峰防护蜡,硫化胶的耐低温性能明显提高,其他性能基本相当,可改善农业轮胎在寒冷地区、寒冷季节易出现龟裂的问题。

Optimization of Tread Compound for Agricultural Tire

The tread compound of agricultural tire was optimized in this study.The results showed that,by properly increasing the addition level of butadiene rubber and reducing the addition level of styrene butadiene rubber in the tread compound,and replacing the unimodal protective wax by equal weight of bimodal protective wax,the low temperature resistance of the vulcanizates was improved significantly,and the other properties changed little.With the optimized compound,the cracking problems of agricultural tire in the cold regions and cold seasons could be reduced.
