新研制合成的硼、氮、硫、磷型多功能润滑防锈添加剂NPBS 与国内外若干商品润滑油及添加剂进行了防锈、腐蚀、润滑、耐磨等性能对比实验。结果表明:含NPBS添加剂油的防锈性能优异,并有较好的极压抗磨润滑性能:对ASTM D—130腐蚀试验效果良好,尤其是对防止紫铜腐蚀变色效果很好,解决了一般硫磷型添加剂对紫铜腐蚀性较大这一棘手问题。 Newly developed NPBS with boron, nitrogen, sulfur and phosphorus multi-functional lubricity antirust additive NPBS and some domestic and foreign commercial lubricants and additives were anti-rust, corrosion, lubrication, wear resistance and other performance comparison experiment. The results show that the oil containing NPBS additive has excellent antirust performance and good extreme pressure antiwear lubrication performance. It has good effect on ASTM D-130 corrosion test, especially for preventing copper from corrosion and discoloration, and solves the problem of general sulfur Phosphorus additive copper corrosion of this thorny issue.
