摘要
以聚氨酯(PU)海绵作为三维支撑材料,吸附氧化石墨烯(GO)和石蜡(PW),制备了改性环氧树脂(EP)复合材料。对该复合材料进行摩擦学性能测试,结果表明:当PW质量为PU的3.5倍时,复合材料的摩擦系数最小,相比纯EP摩擦系数降低了57.77%;当PW质量为PU的2.5倍时,复合材料的比磨损率最低,相比纯EP比磨损率降低了94.08%。采用扫描电子显微镜对复合材料的磨损表面进行表征,认为GO和PW的协同作用对改善复合材料的摩擦学性能起着关键作用。
The modified epoxy resin(EP)composite was prepared by adsorbing graphene oxide(GO)and paraffin wax(PW)using the polyurethane(PU)sponge as the three-dimensional support material.The tribological performance of the composite was tested.The results show that when the mass of PW is 3.5times that of PU,the friction coefficient of the composite is the minimum,which is 57.77%lower than that of pure EP.When the mass of PW is 2.5 times that of PU,the specific wear rate of the composite is the minimum,which is 94.08%lower than that of pure EP.The wear surface of the composite was characterized by scanning electron microscope,and it is believed that the synergistic effect of GO and PW plays a key role in improving the tribological performance of the composite.
