改质剂SPE-100在轻型载重斜交轮胎胎面胶中的应用

Application of modifier SPE-100 in tread compound of LT bias tire

试验研究改质剂SPE-100在轻型载重斜交轮胎胎面胶中的应用效果。结果表明,与生产配方相比,试验配方胶料的t10和t90稍有缩短;硫化胶物理性能相当,耐磨性能显著提高;成品轮胎耐久性能和高速性能达到国家标准要求,虽然每千克增加成本0.03元,但社会效益显著。

The application of modifier SPE-100 in tread compound of LT bias tire was experimen- tally investigated. The results showed that, compared with the existing production compound, the test compound featured shorter tl0 and t90, similar physical properties and higher wear resistance; the endurance and high speed performance of finished tire met the requirements of national standards, the cost was increased by 0.03 yuan · kg^-1 , but the social benefits were better.
