摘　　要：采用KH570对介孔二氧化硅SBA-15进行表面处理,通过原位聚合方法合成SBA-15/不饱和聚酯(UP)复合树脂,后再通过共混、辊炼、模压成型制备了SBA-15/UP复合材料。研究了加入SBA-15对SBA-15/UP复合材料的摩擦磨损性能、硬度、动态力学性能的影响,通过扫描电子显微镜(SEM)对复合材料的磨损表面形貌进行观察。结果表明,经改性后的SBA-15加入使复合材料的体积磨损率降低了26%,玻璃化温度提高了16℃。The mesoporous SiO2 SBA-15 was modified by silane coupling agent KH570, and the SBA-15/unsaturated polyester （SBA-15/UP） in-situ composite resin was prepared. The SBA-15/UP composites were prepared through blending, rolling, compression moulding technology. The influences of the addition of SBA-15 on the friction and wear properties, hardness, dynamic mechanical thermal properties of the SBA- 15/UP composites were studied. The abrasion surfaces of the composites were observed through scanning electron microscope （SEM）. The results show that the volume wear rate of the composites decreases by 26~,and the glass transition temperature of the composites increases by 16 ℃ when the modified SBA-15 is added.
