Polishing lubricant for automobile engine and preparation method of polishing lubricant

Abstract

The invention discloses a polishing lubricant for an automobile engine and a preparation method of the polishing lubricant. The polishing lubricant is prepared from raw materials in parts by weight as follows: 10-45 parts of mineral oil, 15-25 parts of vaseline, 8-10 parts of polyisobutene, 12-25 parts of cellulose ether, 28-35 parts of trisodium phosphate, 15-20 parts of a metal corrosion inhibitor, 30-40 parts of a tackifier, 6-10 parts of sodium acetate, 7-11 parts of monopotassium phosphate, 3-7 parts of methyl silicone oil, 4-8 parts of polyvinyl alcohol, 5-9 parts of glycerol monostearate, 2-3 parts of bisphenol A polycarbonate, 7-10 parts of sulfurized calcium alkyl phenolate, 3-5 parts of magnesium alkyl benzenesulphonate, 6-8 parts of zinc dialkyl dithiophosphate, 3-6 parts of volcanic ore lava nano-powder and 5-8 parts of sodium benzoate. The polishing lubricant can protect an engine against abrasion well, increase the rotation speed of the engine, is abrasion-resistant, squeezing-resistant and high-temperature-resistant, increases oil drain interval, and increases horsepower by 20%, and engine oil does not deteriorate.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to an automobile engine polishing lubricant and a preparation method thereof. Background technique [0002] The operation of the machine depends on the relative movement of the parts, which is bound to be accompanied by friction and wear. Severe friction and wear will also affect the normal operation of the machine. Lubricating oil is a lubricating medium used to reduce the frictional resistance of the friction pair and slow down its wear. Lubricants can also cool, clean and prevent pollution on the friction pair. In order to improve the lubricating performance, suitable additives can be added to some lubricants. When selecting a lubricant, it is generally necessary to consider many factors such as the movement of the friction pair, the material, the surface roughness, the working environment and working conditions, and the performance of the lubricant. In mechanical equi...

Problems solved by technology

Traditional lubricating oil anti-wear and extreme pressure additives mostly use sulfur and phosphorus-based compounds. Such additives have excellent anti-oxidation, anti-corrosion, anti-wear, and extreme pressure functions. However, the use of such additives will produce Air pollution, more and more unsuitable for use as lubricating oil additives
