| 摘 要： | 采用模塑成型法制备氰酸酯树脂(CE)/纳米二氧化硅(nano-SiO2)复合材料,通过磨损率和摩擦系数测试、扫描电子显微镜(SEM)表征,分别考察了nano-SiO2及其经两种偶联剂KH-560和SEA-171表面处理后对CE摩擦学性能的影响.测试结果表明,经偶联剂表面处理后的nano-SiO2能够更加有效地改善CE的摩擦磨损性能,两种偶联剂相比,SEA-171的改性效果较好.SEM分析表明,不同性质的nano-SiO2形成的复合材料,其磨损方式主要表现为磨粒磨损,黏着磨损则随着nano-SiO2未表面处理、KH-560和SEA-171分别表面处理的顺序依此减轻.

| Abstract: | The influence of the nano-SiO2 powders surface treated by coupling agent KH-560 and SEA-171 on the tribological properties of the CE/nano-SiO2 composite was investigated by the moulding method.Results indicated that the nano-SiO2 treated by coupling agent effectively improved the friction and wear performance of CE and SEA-171 showed better effect of modification as compared with KH-560.SEM analysis indicated that the wear mechanism of the composite with nano-SiO2 of various nature was mainly abrasive wear.... |
