摘要
合成了2种无灰无磷的吗啡啉二硫代氨基甲酸酯衍生物2-(morpholine-1-dithiocarbamate)butyl acetate(MCTB)和2-(morpholine-1-dithiocarbamate)hexyl acetate(MCTH),探讨了其在菜籽油中的油溶性、抗腐蚀性,并利用四球摩擦磨损试验机考察了其在菜籽油中的抗磨减摩性能,采用扫描电子显微镜(SEM)分析钢球表面磨斑形貌。结果表明,MCTB和MCTH添加剂在菜籽油中具有良好的油溶性、抗腐蚀性,可以显著地提高菜籽油的承载能力;四球试验钢球磨斑表面平整、光滑、犁沟浅,无腐蚀剥落,具有较好的抗磨性能。MCTH的抗磨减摩性能均优于MCTB。
Two kinds of new synthesized ashless and non-phosphorus morphine-dithiocarbamate compounds———2-（morpholine-1-dithiocarbamate） butyl acetate（MCTB） and 2-（morpholine-1-dithiocarbamate） hexyl acetate（MCTH）,were used as the additive in rapeseed oil.The oil solubility and corrosion-resistance of MCTB and MCTH in rapeseed oil were investigated.Their tribological behaviors in rapeseed oil were evaluated with a four-ball machine,and the surfaces morphology of worn scar of steel ball was analyzed by scanning electron microscopy（SEM）.The results showed that the two compounds had good oil solubility and corrosion-resistance in rapeseed oil,and the load-carrying capacity,wear-reducing and friction-reducing ability of rapeseed oil could be extremely improved as they were as the additive.The worn surfaces of steel ball after four-ball test of rapeseed oil contained 2.0% MCTB or MCTH were smooth,and had light furrows but exfoliation because of corrosion.The tribological performance of MCTH in rapeseed oil was better than that of MCTB.
