Lubricating oil for piston

Abstract

The utility model provides a lubricating oil for a piston, which comprises the following raw materials in part by weight: 3-5 parts of monoethanolamine, 2.5-3.5 parts of sodium methylene bis-naphthalene sulfonate, 2-3 parts of acrylic acid-2-ethyl ester, 3-5 parts of zinc sulfate, 5-9 parts of sodium dodecylbenzene sulfonate, 8-14 parts of ultra-high alkali synthesis calcium sulfonate, 3-5 parts of trilinolein, 4-7 parts of calcium sulfurized alkyl phenate, 2-5 parts of modified polysiloxane, 1-4 parts of stannous sulfate, 2-5 parts of zinc dialkyl dithiophosphate, 2-5 parts of phenyl-naphthyl amine, 2.3-4.5 parts of boride polyisobutylene succinimide, and 26-36 parts of low-viscosity poly-alpha-alkene. The lubricating oil is applied to pistons and has the advantages of good lubricating effect, high wear resistance and good high pressure resistance.

Description

technical field [0001] The present invention relates to a lubricating oil for pistons. Background technique [0002] The piston is a part that looks like the heart of the engine. It bears alternating mechanical loads and thermal loads. The working environment of the piston is very harsh. It works under the pressure of high temperature, high pressure and high speed operation, and the top of the piston is still burning. The components of the chamber, the piston is in direct contact with the high-temperature gas, and sometimes the temperature can reach above 2500K instantaneously, and the sealing performance of the piston is also very high, and it is also subjected to the chemical corrosion of the gas, so the lubrication of the piston follows the automobile engine. The increase in the number of lubricants is becoming more and more difficult to do, and the requirements for lubricants are getting higher and higher, and it is difficult for ordinary lubricants to meet the standards...
