Piston lubricating oil with sealing function

Abstract

Piston lubricating oil with the sealing function is prepared from the following raw materials in part by weight: 3-4 parts of gelatin, 4-5 parts of sodium silicate, 1-2 parts of oxazolidine, 4-8 parts of nonyl phenol polyoxyethylene ether, 2-3 parts of sodium citrate, 5-7 parts of dichloromethane, 5-9 parts of hydroxypropyl methacrylate, 4-6 parts of trimethyl decane, 4-7 parts of calcium alkylbenzene sulfonate, 5-9 parts of petroleum sodium sulfonate, 4-7 parts of trilinolein, 2-5 parts of sulfurized calcium alkyl phenate, 5-8 parts of benzoic acid, and 4-6 parts of polytetrafluoroethylene. The piston lubricating oil has the benefits of being excellent in corrosion resistance and ageing resistance, and capable of guaranteeing the sealing property of an air cylinder to prevent power reduction.

Description

technical field [0001] The invention relates to a sealed piston lubricating oil. 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.
