摘要
研究热稳定剂HS-80在轿车子午线轮胎、全钢载重子午线轮胎和工程机械轮胎胎面胶中的应用。结果表明:加入热稳定剂HS-80,胶料的门尼粘度明显减小,挤出工艺性能明显改善,硫化特性总体变化不大;硫化胶的300%定伸应力、拉伸强度、撕裂强度提高,压缩疲劳温升降低,耐磨性能、耐疲劳性能和耐热性能改善;成品轮胎的高速性能和耐久性能好。
The application of heat stabilizer HS-80 in the tread compound of passenger car radial tire, TBR tire and OTR tire was investigated. By adding heat stabilizer HS-80, the Mooney viscosity of the compound significantly reduced, the extrusion processing property was significantly improved, and the curing characteristics changed little. The tests on the vulcanized rubber showed the modulus at 300% elongation, tensile strength, tear strength, compression temperature rise, wear resistance, fatigue resistance and heat resistance were improved. The test results of the finished tires showed that the high speed performance and endurance performance were excellent.
