在苯酚预聚物中分别添加其质量分数为1.5%的纳米蒙脱石(M)和坡缕石(P),原位聚合了2种酚醛树脂(分别记为 PF/M和 PF/P).用热分析仪对其进行了 TG 分析.将合成的PF/M和PF/P为基体分别制备半金属摩擦材料,按照 GB5763—2008在 XD-MSM定速式摩擦磨损试验机上进行摩擦学性能测试.结果表明：纳米粒子份数为1.5%PF/M的耐热性及其摩擦材料的摩擦学性能均明显优于未有纳米粒子复合的 PF 和 PF/P,在600℃时PF/M残炭率较PF/P高4%,较PF高12%,所制备的摩擦材料试样的抗热衰退温度较PF/P和PF树脂摩擦材料分别提高约50℃和100℃,且摩擦因数稳定,350℃高温时段的磨损率较FP-1.5和F-0.0分别降低16.8%和27%.

1 .5% of the nano montmorillonite (M)and palygorskite (P)were separately added to the phenol prepolymer,and phenolic resins were synthesized in in-situ method (called PF/M and PF/P).The TG analysis of the synthetic resins was carried out.The synthetic resins PF/M and PF/P were used as the new resin matrix to prepare semimetal friction material samples.Tribological performance test was carried on an XD-MSM fixed speed type friction-wear the testing machine.The results show that the heat resist-ance of PF/M by nano-particles for 1 .5% and its tribological performance of friction material are better than no nanoparticle composite PF and PF/P.The carbon residue rate of mass fraction of 1 .5% synthetic resin PF/M is more than PF/P and PF,separately increased by 4% and 12% at 600 ℃.The temperature thermal recession of the sample prepared by PF/M is increased by 50 ℃ and 100 ℃ more than the sample prepared by PF/P and no nano-particles composite resin,and has stable friction coefficient.Its wear rate is separately reduced by 16.8% and 27% than FP-1.5 and F-0.0 at the high temperature of 350 ℃.
