Application of Thermal Stabilizer TCA-90 in Tread Base Compound of All Steel Radial Tire

研究热稳定剂TCA-90在全钢子午线轮胎胎面基部胶中的应用。结果表明:在胎面基部胶中加入1. 5份热稳定剂TCA-90,胶料的抗硫化返原性能明显提高,工艺性能良好;硫化胶的物理性能较好,耐热和耐老化性能提高;成品轮胎的耐久性能提高。

The application of thermal stabilizer TCA-90 in the tread base compound of all steel radial tire was studied. The results showed that,by adding 1. 5 phr thermal stabilizer TCA-90 in the tread base compound,the anti reversion property of the compound was significantly improved,and the processing property was good. The physical properties of the vulcanizate were better,and the heat resistance and aging resistance were improved. The durability of the finished tire was improved.
