LSR-395树脂在全钢载重子午线轮胎带束层胶和胎体帘布胶中的应用

Application of LSR-395 Resin in Belt Compound and Carcass Cord Compound of Truck and Bus Radial Tire

研究LSR-395树脂在全钢载重子午线轮胎带束层胶和胎体帘布胶中的应用。结果表明:在带束层胶和胎体帘布胶中以LSR-395树脂等量部分替代间苯二酚-80,间苯二酚-80在胶料中的分散性和使用效率提高;胶料的各项物理性能相当;湿热老化条件下胶料对钢丝帘线的粘合力和覆胶率稍低,其他测试条件下胶料对钢丝帘线的粘合力和覆胶率相近或有提高;成品轮胎的室内耐久性能相当。

The application of LSR-395 resin in the belt compound and carcass cord compound of truck and bus radial tires was studied.The results showed that by using LSR-395 resin to partly replace resorcinol-80 in equal weight,the dispersibility and use efficiency of resorcinol-80 were improved.Meanwhile,the physical properties of the compound were comparable.Under the condition of damp and heat aging,the adhesive force and the coated compound rate of the compound to steel cord were slightly lower,and under other test conditions,the adhesive force and the coated compound rate were similar or even increased.The indoor durability of the finished tire was comparable.
