摘要
通过调整胎面胶、胎侧胶、上三角胶的胶料配方,开发具有低滚动阻力的全钢载重子午线轮胎。结果表明:与对照配方相比,试验配方胎面胶的100%定伸应力增大,300%定伸应力、拉伸强度和拉断伸长率减小;试验配方胎侧胶的300%定伸应力增大,拉断伸长率减小;试验配方上三角胶的拉伸强度略减小,其他物理性能均相当;试验配方胎面胶、胎侧胶和上三角胶的压缩疲劳温升、60℃时的损耗因子和Payne效应都明显减小,表明试验配方胶料的滚动阻力低、生热小、填料聚集程度减弱;与对照轮胎相比,试验轮胎的滚动阻力系数减小23.5%,可达B级水平,耐久性能提高约6%。
Truck and bus radial tires with low rolling resistance were developed by adjusting the formula of tread compound,sidewall compound and upper apex.The results showed that,compared with the control formula,the modulus at 100% elongation of the tread compound of the test formula increased,the modulus at 300% elongation,tensile strength and elongation at break decreased.The modulus at 300% elongation of the sidewall compound of the test formula increased,the elongation at break decreased,the tensile strength of the upper apex of the test formula decreased slightly and other properties were equivalent.The compression fatigue temperature rise,loss factor at 60 ℃ and Payne effect of the tread compound,sidewall compound and upper apex of the test formulations were significantly reduced,which indicated that the rolling resistance of the test compound was low,the heat build-up was small and the degree of filler aggregation was weakened.Compared with the finished control tire,the rolling resistance coefficient of the finished test tire was reduced by 23.5%,the rolling resistance coefficient could reach the B-level and the durability performance was improved by about 6%.
