2200dtex/2 E90聚酯帘布在载重轮胎胎体中的应用

Application of 2200dtex/2 E90 Polyester Cord in the Carcass of Truck Tire

研究2200dtex/2 E90聚酯帘布(简称聚酯帘布)在载重轮胎胎体中的应用。结果表明:胎体胶采用防老剂A/BLE替代防老剂4020,可提高其与聚酯帘布的粘合性能;聚酯帘布含水率应小于1%,存放时间宜在48 h内;聚酯帘布适宜的压延速度为45 m·min^(-1);与胎体采用2100dtex/2锦纶6帘布的载重轮胎相比,胎体采用聚酯帘布的载重轮胎胎体强度较大,耐久性能好。

The application of 2200dtex/2 E90 polyester cord（referred to polyester cord） in the carcass of truck tire was investigated. The experimental testing results showed that the adhesion between the polyester cord and carcass compound was improved when the antioxidant A/BLE instead of antioxidant 4020 was used in the compound. The moisture content of polyester cord had to be controlled below 1% and the storage time should be within 48 hours. The suitable calendaring speed was 45 m·min^-1. It was found that compared with the truck tire with 2100dtex/2 nylon 6 cord in the carcass,the truck tire with 2200dtex/2 E90 polyester cord in the carcass possessed higher carcass strength and better durability.
