摘要

摘要: 制备了不同树脂基体和不同树脂含量的汽车摩擦材料,研究了树脂种类与含量对汽车摩擦材料的机械性能和摩擦磨损性能的影响。结果表明,腰果壳油改性酚醛树脂为基体的摩擦材料的摩擦、耐热和力学性能,均优于纯酚醛树脂基摩擦材料。树脂-丁腈橡胶共混改性摩擦材料具有更好的力学性能和耐磨性,摩擦系数稳定。随着树脂粘结剂含量的增加,摩擦材料的力学性能提高。树脂粘结剂的含量在9%~12%时,摩擦材料具有优异的摩擦磨损性能;树脂粘结剂的含量小于6%时,摩擦系数较低且不稳定;树脂粘结剂的含量大于15%时,材料发生热衰退现象。

Abstract: Automotive friction materials were prepared with different kinds of resins and different resin contents. The effects of resin on mechanical and friction properties of automotive friction materials were studied. The results show that friction materials with YSM modified phenolic resin have better mechanical and friction properties than those with pure phenolic resin. Friction materials by Resin-NBR mixing modification have good mechanical properties, wear-resistance and smooth coefficient. With the increase of resin content, the mechanical properties of friction materials are improved. With the resin content of 9%~12%, the materials have excellent friction and wear properties. When the resin content is less than 6%, the friction coefficient of materials is low and unstable. And when more than 15%, the friction materials begin to decay at high temperatures.
