Problems solved by technology

[0004] With the strengthening of internal combustion engine power, the increase of speed, and higher standards for its vibration stability and low-carbon environmental protection, new technical requirements have been put forward for internal combustion engine thrust plates, especially for its anti-friction layer. The anti-wear and anti-friction properties, adhesion, and thermal stability of internal combustion engine bearing bushes and thrust pad surface coatings need to be improved. In high-speed, high-load engines, the wear rate is high and cannot meet the new technical requirements.

Abstract

The invention relates to a printing solution for forming the antifriction layer of a sliding bearing. The printing solution is prepared from the following components in parts by weight: 10-50 parts of a polybenzimidazole resin solution, 20-60 parts of a molybdenum disulfide solution and 0.5-6 part of a silicon carbide ceramic solution, wherein the polybenzimidazole resin solution is prepared by mixing and stirring polybenzimidazole resin, dimethylbenzene, ethylbenzen, and triethanolamine according to the weight ratio of 2:1:1:1, the molybdenum disulfide solution is prepared by mixing and stirring molybdenum disulfide powder, N-methyl-2-pyrrolidone and polyethylene glycol according to the weight ratio of 3:5:2, the silicon carbide ceramic solution is prepared by adding the 50VOL% ethanol solution into silicon carbide ceramic powder, and the pH value of the silicon carbide ceramic solution is between 9 and 10. The invention further provides a preparation method of the printing solution and the antifriction layer of the sliding bearing for an internal combustion engine, which is prepared by using the printing solution.

Description

technical field [0001] The invention relates to a printing solution for forming a friction-reducing layer of a sliding bearing, in particular to a printing solution applied to the working surfaces of bearing bushes and thrust pads of internal combustion engines made of materials such as CuPb24Sn, CuPb20Sn4, AlSn10Cu, AlSn20Cu, CuSn10Bi3, and solidified by printing The process produces a printing liquid for a friction-reducing high-temperature (260° C.) friction-reducing layer (ceramic coating) and a preparation method thereof. Background technique [0002] The working surface layer of the internal combustion engine sliding bearing, also known as the anti-friction layer. Since the 1940s, lead-based alloys have been used as friction-reducing layer materials for bearing pads and thrust pads. Due to their good characteristics, they have been increasingly widely used and developed. In the past 50 years, people have developed PbSnCu, PbSnCuIn and other ternary and quaternary allo...
