摘要
以油酸和氧化镁为原料在165℃下制得了油酸镁,利用红外光谱对其分子结构进行了表征,将油酸镁加入液体石蜡基础油中,发现其在液体石蜡中可稳定分散。用四球摩擦磨损实验机对油酸镁的摩擦学性能进行了考察,并用SEM和EDS对磨斑表面进行了研究。结果表明,油酸镁质量分数为3%时,可使液体石蜡基础油的磨斑直径降低32%;含油酸镁的液体石蜡润滑时,在摩擦表面发生了复杂的化学反应,生成的反应膜使润滑油具有良好的抗磨性能。
Oil soluble magnesium oleate was synthesized at 165℃ and characterized by means of FT-IR. Its tribological properties as antiwear additives were evaluated by four-ball friction and wear tester. SEM and EDS were used to analyse the wear sear surface. The results indicate that the synthesized magnesium oleate can be dispersed in base oil stablely. When lubricated by liquid paraffin containing 3% oil soluble magnesium oleate, the wear sear diameter is decreased at 32% , and complex tribochemical reactions occur on the surface of friction pair and the film formed by these reactions can remarkablely improve the antiwear ability of the base oil.
