【摘要】：合成一种水溶性润滑添加剂2,4-双-(二乙醇胺基)-6-(O,O'-二乙醇胺基二硫代磷酸酯)-S-基-1,3,5-均三嗪化合物(DDT),利用四球摩擦试验机考察其在水-乙二醇基础液中对YG8硬质合金钢球的润滑性能。结果表明:该化合物作为水基润滑添加剂可使水-乙二醇基础液的极压值提高了近5倍,并且可使硬质合金钢球磨斑直径和磨痕明显减小,表现出优异的抗磨减摩性能;通过SEM和EDS分析,可推测该水溶性化合物在摩擦过程中可能发生化学反应生成了磷酸钨、二硫化钨等化学膜,也可能生成一些含S、N小分子有机物组成的边界润滑膜,从而起到了良好的抗磨减摩作用。
[Abstract]:Synthesis of a Water-soluble Lubricating Additive 2O4- (diethanolamine) -6- (OOO- diethanolamine dithiophosphate) -S- (1-triazine) -5-triazine compound (DDT), The lubricating properties of YG8 cemented carbide steel balls in water glycol base liquid were investigated by four ball friction tester. The results show that the extreme pressure of water-glycol base liquid can be increased by nearly 5 times as the additive of water-based lubrication, and the diameter and wear mark of wear spot of cemented carbide steel ball can be reduced obviously, showing excellent anti-wear and anti-friction performance. Through the analysis of SEM and EDS, it can be inferred that the chemical reaction of the water-soluble compound in the friction process may result in the formation of tungsten phosphate, tungsten disulfide and other chemical films, as well as the formation of some boundary lubricating films consisting of small organic compounds containing Sn-N. Thus, it plays a good role in anti-wear and anti-friction.
