Lubricating oil

Abstract

The invention relates to a lubricating oil which mainly solves the problems of low stability, poor lubricating effect and short service life in the existing common lubricating oil. The invention is characterized in that the lubricating oil is prepared from the following components in parts by weight: 350-450 parts of lubricating oil base oil, 15-35 parts of polymethacrylate, 10-20 parts of high-base-number sulfurized calcium alkyl phenate, 11-15 parts of magnesium hydroxy silicate, 11-15 parts of molybdenum dibutyl dithiocarbamate, 12-17 parts of isooctyl oleate, 12-20 parts of polyisobutylene succimide, 5-8 parts of molybdenum dialkyl dithiocarbamate, 10-20 parts of dimethyl silicone oil, 5-10 parts of sorbitan monooleate and 2-5 parts of epoxyethane/epoxypropane block polymer ether. The lubricating oil has the advantages of excellent comprehensive properties, favorable stability, favorable lubricating property, favorable defoaming property, favorable oxidation resistance and favorable abrasion resistance, and has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a lubricating oil. Background technique [0002] Lubricating oil is a liquid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the role of lubrication, cooling, cleaning, sealing and buffering. [0003] 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, meet higher requirements, and are an important part of lubricating oil. . Lubricating oil has the characteristics of high technical content, complex production process, various varieties and specifications, and high added value of products. [0004] At present, the lubricating oil that people use is c...
