几种含磷摩擦改进剂在150BS光亮油中的摩擦学性能研究

STUDY ON TRIBOLOGICAL PROPERTIES OF SEVERAL P-CONTAINING FRICTION MODIFIERS IN 150BS BRIGHT STOCK

采用四球摩擦试验机和SRV摩擦磨损试验机等考察了亚磷酸烷基酯、酸性磷酸酯胺盐和硫代磷酸酯3种含磷摩擦改进剂在150BS基础油中的摩擦学性能,采用三维轮廓形貌仪对磨斑表面进行了分析对比,采用MTM2型微牵引力试验机考察了油品的牵引因数,采用VKA 110四球试验机测试了油品的温升情况。结果表明:3种含磷剂均不同程度改善了150BS基础油的摩擦学性能;其中酸性磷酸酯胺盐在150BS基础油中具有更为优异的抗磨减摩性能,在承载能力、牵引因数和温升方面对油品具有更大的改善。

The tribological properties of several P-containing friction modifiers in 150BS stocks were evaluated by four-ball tester and SRV testing machine.The modifiers are alkylphosphite,acidic phosphate ester amine salt and thiophosphate.The wear scars on the surface of steel ball tested were investigated by three-dimensional morphology,the traction coefficients were observed by MTM2 test machine and the temperature rises were tested by VKA110 four-ball test machine.The results showed that three kinds of friction modifiers could improve the tribological properties of 150BS base oil in different degrees.In particular,acidic phosphate ester amine salt exhibits superior anti-wear,friction reduction properties in 150BS base oils and supplies great improvements in bearing capacity,traction coefficient and temperature rise.
