Abstract

The invention relates to a lubrication oil antiwear additive, which is characterized by consisting of base oil, dispersant, nanoscale metal powder, pour point depressant and viscosity index improver, wherein the nanoscale metal powder comprises copper oxide powder, magnesium powder, manganese powder and chromium powder. The dispersant is a polyisobutylene-bis-succinimide; the pour point depressant is polymethacrylate; and the viscosity index improver is ethylene propylene copolymer (OCP). The invention has the advantages that the manufacturing method is simple and practical, and the manufactured additive has low cost and good oil solubility, can have good antiwear effect on various kinds of lubrication oil, has good antifriction and repair functions and has no corrosion to the inside of the machine.

Description

technical field [0001] The invention relates to an anti-wear additive for lubricating oil, in particular to a preparation method for the anti-wear additive for lubricating oil. Background technique [0002] With the progress of society, engine technology is developing rapidly, and various mechanical equipment is constantly being updated, which puts forward higher requirements on the performance of lubricating oil, and the use of anti-wear additives can greatly improve the overall performance of lubricating oil. However, the anti-wear additives commonly used in the domestic market are unsatisfactory, and the high-quality lubricating oil anti-wear additives abroad are very expensive. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the speed-up technology, and provide a low-cost lubricating oil wear-resistant additive that has obvious anti-wear, wear-reducing and repair functions for engines and machinery, has no co...
