Aimed at the problems of poor bearing capacity and pollution environment of wet flange lubrication method,two kinds of thermosetting flange lubricating materials were prepared with thermosetting resin and lubricant MoS2 as the main raw materials by the method of molding pressing.The friction and wear properties of the lubricating materials were investigated by M200 friction tester.The structure,composition,worn surface morphology and element composition of the materials were analyzed by Xray Diffraction,Infrared Spectroscopy and Scanning Electron Microscopy.The mechanism of lubrication and wear of the materials was analyzed and discussed.The results show that,for the two kinds of thermosetting lubricating materials,the No1 lubricating material containing the friction modifier has better mechanical properties than the No2 lubricating material without the friction modifier.During the friction process,the No.1 lubricating material can form uniform and continuous transfer film on the friction surface,and the friction coefficient is low and stable,the wear rate is also lower.The friction modifier promotes the curing of the thermosetting resin and the dispersion of the lubricant in the thermosetting resin,which improves the mechanical properties of the material.The synergistic effect of the friction modifier and MoS2 promotes the formation of uniform transfer film,which improves the bearing capacity and wear resistance of the solid lubricating material.
