Lubricant additive of internal combustion engine

Abstract

The invention discloses a lubricant additive of an internal combustion engine. The lubricant additive comprises, by weight, four to five parts of lauryl acidic phosphite ester, three to four parts of methylacrylate, two to three parts of crylic acid glyceride, three to seven parts of polyisobutylene succinimide, seven to ten parts of diethanol amine, four to seven parts of dodecylbenzene, 17-18 parts of carbon tetrachloride, 10-15 parts of hydrofluoric acid, 20-30 parts of petroleum ether and five to six parts of benzyl alcohol. The problem that the viscosity of lubricant is increased due to temperature rising is solved.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to an additive for lubricating oil of an internal combustion engine. Background technique [0002] At present, lubricating oil is widely used in the field of machinery. With the different operating environments of machinery, the requirements for lubricating oil are not the same. Some lubricating oils need high temperature resistance, and some need to enhance wear resistance. Contents of the invention [0003] The object of the present invention is to provide an internal combustion engine lubricating oil additive to solve the problem of lubricating oil viscosity increase due to temperature rise. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] An internal combustion engine lubricating oil additive, according to parts by weight, comprising: [0006] Lauryl acid phosphite: 4-5 parts; [0007] Methacrylate: 3-4 parts; ...
