摘要
合成了一种新型无磷苯并三氮唑衍生物(BTB),利用四球摩擦磨损试验机考察了单剂BTB、磷酸三丁酯(TBP)以及不同配比的BTB和TBP的复合添加剂在液体石蜡中的摩擦磨损性能;用带散射能谱的扫描电镜分析了磨损表面形貌和元素分布。结果表明:所合成的BTB添加剂能提高基础油的承载能力和减摩、抗磨性能,并且与TBP具有协同作用;在摩擦过程中发生物理、化学吸附的同时,与金属表面发生摩擦化学反应,生成一层复合膜,从而起到了极压抗磨作用。
A novel non-phosporus benzotrizole derivative (BTB) was synthesized, and the tribological properties of BTB, commercial additive tributhyl phosphate (TBP) and mixtures of BTB and TBP with different mole ratios as additives in liquid paraffin were examined with four-ball tester. Worn surface morphology and element chemistry configuration of steel ball were analyzed by scanning electron microscopy with EDS. Results indicate that all additives increased the load-carrying capacity of the base oil, and possess antiwear and antifriction performances of the base oil. Combination of BTB and TBP showed synergistic effect in load-carrying, antiwear and frictionreducing in base oil. The additives reacted with counterface metal and generated a boundary lubricating and protecting film which improved tribological properties of the base oil.
