Problems solved by technology

Organic additives can form a thin layer of membranes between adjacent substrates, such as adsorption membranes, permeable membranes, reaction membranes, etc., which play a good role in reducing friction, but the membranes have poor high temperature resistance and are prone to It decomposes at high temperature, which significantly reduces the lubricating effect, and the decomposed organic matters have adverse effects on both equipment and air

Abstract

The invention discloses high-temperature-resistant lubricating oil for engines and a preparation method of the lubricating oil. The lubricating oil is prepared from components in parts by weight as follows: recycled lubricating oil, poly-alpha-olefin, polyethylene glycol, graphite fibers, nano molybdenum powder, nano cerium oxide powder, nano calcium borate, sodium stibogluconate, bismuth potassium citrate, 1,8-naphthalene sulfonic acid lactone, allyl isothiocyanate, glycolic acid, 9-fluorenone-2-carboxylic acid, sodium phosphotungstate, zirconium naphthenate, octyl-butyldiphenylamine, silicon carbide powder, benzotriazole, methyl silicone oil and boronized polyisobutenyl succinimide. The indicative lubricating oil has a four-ball test at the temperature of 220 DEG C and under the condition of 800 rpm and has smaller wear spot diameters, and the maximum non-seizure load PB shows that the lubricating oil has a good lubricating property and abrasive resistance at the high temperature, is applicable to the engines in the high-temperature environment and has wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of lubricant oil, and in particular relates to a high-temperature-resistant lubricating oil for an engine and a preparation method thereof. Background technique [0002] Lubricating oil plays an important lubricating role in mechanical transmission and is mainly used in mechanical equipment, automobiles, home appliances and other fields. Lubricating oil is generally composed of base oil and additives. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil and give new performance to lubricating oil. [0003] In practical applications, in order to increase the lubricating effect of lubricating oil, anti-wear agents are often added. Anti-wear agents are mainly divided into two categories, one is solid additives, usually molybdenum disulfide, boron nitride and other carbon materials, etc.; the o...
