Abstract

The invention discloses an anti-wear agent for mechanical lubricating oil and a preparation method of the anti-wear agent. The anti-wear agent is prepared from components in parts by weight as follows: 10-20 parts of sulfurized isobutene, 15-30 parts of chlorinated paraffin, 4-12 parts of ricinoleic acid, 3-8 parts of silica powder, 3-14 parts of nano titanium dioxide powder, 2-8 parts of magnesium oxide, 4-10 parts of cellulose sulfate, 2-8 parts of sulfonated graphene and 5-15 parts of nano-molybdenum disulfide. The preparation method is simple, and by means of the prepared anti-wear agent, engine wear can be reduced, and working life of each friction part can be prolonged.

Description

technical field [0001] The invention relates to the technical field of preparation of antiwear agents, in particular to an antiwear agent for mechanical lubricating oil and a preparation method thereof. Background technique [0002] With the increasingly stringent environmental protection regulations, the control of indicators such as sulfur content in diesel oil is becoming more and more stringent. The refinery must reduce the sulfur content through deep hydrotreating. At the same time, some natural lubricating substances in diesel oil are also removed, resulting in a significant decline in the lubricating performance of diesel oil. In order to improve the lubricity of low-sulfur diesel oil, adding diesel antiwear agent is a very effective means to improve the lubricity of diesel oil. At present, the most economical and effective oil lubrication improvers for low-sulfur diesel are three types: unsaturated fatty acid, unsaturated fatty acid ester and fatty acid amide. The ...
