丁苯橡胶矿用工程机械轮胎胎面胶的研究

SBR Tread Compound for Mining OTR Tire

介绍丁苯橡胶(SBR)矿用工程机械轮胎胎面胶的研究。结果表明,与天然橡胶/SBR(并用比70/30)矿用工程机械轮胎胎面胶相比,优化配方的SBR矿用工程机械轮胎胎面胶耐屈挠性能提高,老化前后的定伸应力、拉伸强度、拉断伸长率、撕裂强度增大,成品轮胎耐久性能改善,原材料成本降低。

In this study, the tread compound of mining OTR tire was developed using SBR. Compared with tread compound using NR/SBR blend with a ratio of 70/30, the tread compound with optimized SBR formula showed better flex resistance, increased tensile strength, tensile modulus, elongation at break and tear strength, and better aging resistance. The finished tire with SBR tread compound possessed better endurance performance and the material cost was reduced.
