轻型载重斜交轮胎胎面胶配方优化

Optimization for tread formula of LT tire

应用纳米氧化锌对轻型载重斜交轮胎胎面胶配方进行优化设计。试验结果表明,通过应用纳米氧化锌,调整生胶比例和减小炭黑用量,可以改善胎面胶挤出工艺性能,显著降低胎面胶的生热和压缩永久变形,提高成品轮胎胎面胶的300%定伸应力和拉伸强度,使轮胎肩空退赔率大幅度降低。

The tread formula of LT tire was optimized by using nano-zinc oxide. The test results showed that the extrudability of tread compound improved, the heat build-up and compression set of tread decreased significantly, the modulus at 300% and tensile strength of the tread in finished tire increased,and the compensation rate of tire caused by shoulder seperation reduced remarkably by using nano-zinc oxide,adjusting raw rubber content and blending ratio,and decreasing additional level of carbon black.
