采用一步水热法将不同质量比的氧化石墨烯(GO)和固体石蜡(PW)吸附在玄武岩毡(BF)上制备三维(3D)润滑增强体, 浇铸环氧树脂(EP)合成一系列EP/BF/GO/PW复合材料。研究了不同质量比GO/PW对EP基复合材料摩擦学性能的影响, 采用扫描电子显微镜、X射线衍射光谱仪对复合材料的形貌和结晶性进行表征分析。结果表明:当GO与PW的质量比为1∶3时, 复合材料的摩擦学性能最优。与纯EP相比, EP/BF/GO/PW(1∶3)复合材料的摩擦系数和体积磨损率分别降低了77.50%和14.36%, 同时硬度提高了12.16%。
3D lubrication reinforcement was prepared by adsorbing graphene oxide (GO) and solid paraffin wax (PW) with different mass ratios on basalt felt (BF) using one-step hydrothermal method.A series of EP/BF/GO/PW composites were prepared by casting epoxy resin (EP).The effects of different mass ratios of GO/PW on the tribological properties of EP-based composites were investigated, and the morphology and crystallography were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD).The results showed that when the mass ratio of GO to PW was 1∶3, the tribological properties of the composites reached the best level.Compared with pure EP, the friction coefficient and volume wear rate of EP/BF/GO/PW (1∶3) composites decreased by 77.50% and 14.36%, respectively.Simultaneously, the hardness increased by 12.16%.
