Problems solved by technology

[0003] For the existing lubricating oil, in the high-speed, high-pressure and high-temperature working environment between parts, the friction surface of the lubricating oil will be damaged, resulting in uneven friction surface of the lubricating oil, and the lubricating oil itself does not have the function of automatic repair. During normal operation, new lubricating oil needs to be replaced, which is time-consuming

Abstract

The invention discloses novel nanometer self-repairing lubricating oil. The novel nanometer self-repairing lubricating oil comprises the following raw materials in parts by weight: 76-91 parts of base oil, 15-20 parts of nanometer metal powder, 5-8 parts of a nanometer metal powder dispersing agent, 8-14 parts of a lubricating oil additive, 8-10 parts of graphene oxide, 7-9 parts of nitrite, 7-8 parts of calcium chloride, 10-12 parts of magnesium chloride, 7-9 parts of magnesium acetate, 10-11 parts of polyvinyl alcohol, 14-15 parts of sodium polyacrylate, 14-16 parts of p-hydroxybenzaldehyde, 3-4 parts of propylene glycol and 3-5 parts of dithiol. A lubricating oil friction surface damaged after long-time use can be automatically repaired, the situation that the friction surface is concave and convex is avoided, the friction surface is more regular and smoother, and lubricating effect can be stably achieved in machines for a long time.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a novel nanometer self-repairing lubricating oil. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, endow some new properties, and are an important part of lubricating oil. [0003] For the existing lubricating oil, in the high-speed, high-pressure and high-temperature working environment between parts, the friction surface of the lubricating oil will be damaged, r...
