摘　　要：研究两种热稳定剂SL-9090和HS-80在全钢载重子午线轮胎胎面胶中的应用。结果表明:在胎面胶中加入热稳定剂,胶料的门尼粘度减小,硫化速度减慢,抗硫化返原性提高,且与热稳定剂用量呈正比,加入2份热稳定剂HS-80的胶料抗硫化返原性最好;硫化胶的物理性能变化不大,生热相当,其中加入3份热稳定剂SL-9090的胶料耐高温性能最优。The application of two kinds of heat stabilizers SL-9090 and HS-80 in the tread compound of truck and bus radial tire was studied.The results showed that by adding heat stabilizers in the tread compound,the Mooney viscosity of the compound decreased,the curing speed slowed down and anti-reversion property improved,which was directly proportional to the amount of heat stabilizer,and the anti-reversion property of the compound by adding 2 phr heat stabilizer HS-80 was the best.By adding heat stabilizer,the physical properties of the vulcanizate changed little,and the heat build-up was equivalent,the high temperature resistance of the compound by adding 3 phr heat stabilizer SL-9090 was the best.
