巨型工程机械子午线轮胎高强度低生热胎面基部胶配方开发

Development of High Modulus and Low Heat Build-up Tread Base Compound of Giant Off-The-Road Radial Tire

通过对国外知名品牌37.00R57和40.00R57规格巨型工程机械子午线轮胎胎面基部胶组成分析和物理性能测试,对我公司巨型工程机械子午线轮胎胎面基部胶配方进行优化设计。新开发配方半成品和成品胶料动态损耗因子分别降低37.9%和26.6%,胶料物理性能达到竞品水平,成品轮胎TKPH提升13.6%。

In this study,the tread base compound formula of giant off-the-road radial tire was optimized.The test results showed that the dynamic loss factors of newly developed semi-finished and finished compound were reduced by 37.9%and 26.6%,respectively,and the physical properties of the compound reached the same level of competitor’s products,such as 37.00R57 and 40.00R57 giant off-the-road radial tires produced by well-known foreign tire manufacturer.The TKPH of the finished tire was increased by 13.6%.
