摘　　要：采用酸酐、601和618混合环氧树脂、胶体二硫化钼及特殊溶剂和添加剂等制备成的热固性二硫化钼干膜润滑剂,涂层经200℃、固化2h后形成了润滑减摩层。结果表明,其膜层不仅附着力、防腐性、耐高低温性及耐液体介质性好,而且在热真空环境下工作性能稳定、摩擦系数低、耐磨寿命长。Thermosetting MoS2 dry film lubricant was obtained by the use of anhydride,601 and 618 epoxy resin,colloidal MoS2 and special solvent and additives.The lubricant was cured to form coating in 2h at 200℃.The lubricant coating shows excellent adhesion,resistance to corrosion,high and low temperature,liquid medium.In thermal vacuum the coating also has the features of stable performance,low friction coefficient and long wear life.
