| 摘 要： | 通过试验机将3种不同的坡缕石和3种不同的丁腈改性酚醛树脂分别热压制成不同的二元摩擦材料,研究了其摩擦磨损和耐冲击性能,结果表明,在高温阶段,坡缕石原矿与纳米改性树脂形成的摩擦材料性能比未改性丁腈酚醛树脂更好,铝锆偶联剂改性坡缕石与Al2O3纳米粒子改性树脂组成材料的摩擦磨损性能较未改性丁腈酚醛树脂有所下降,XD-172改性坡缕石与纳米Al2O3改性丁腈酚醛树脂组成材料的摩擦磨损性能在低温阶段有所提高。

| Abstract: | Three types of palygorskites and three types of NBR-modified phenolic resin are compressed respectively into new dual friction materials by material testing machine.Their friction,wear and impact resistance performances are studied experimentally.The results show that modified friction materials made of palygorskites raw ore and nano-particle modified NBR phenolic resin have better performance than unmodified phenolic resin mixed materials in high temperature stage.But compared with NBR-modified phenolic resin,the friction and wearing performances of dual friction material compressed by palygorskites by Al-Zr coupling agent and modified phenolic resin by Al2O3 nanoparticles decrease a little bit and the mixed modified material by XD-172 has better effect only at the low temperature stage. |
