Abstract

The invention provides a clean vacuum pump oil. The clean vacuum pump oil comprises the following raw materials by weight: 15 to 30% of oil-soluble polyether, 60 to 76% of trimellitate, 5 to 15% of alkyldiphenyl ether, 1 to 2% of an emulsion inhibitor, 1 to 2% of an air compressor oil complexing agent, 1 to 2% of an anti-oxidant and 0.02% of an antifoaming agent, summing to 100%. Through adoptionof proper composition and reasonable usage amounts, the raw materials for preparation of the clean vacuum pump oil better perform synergism; a specific process is used so as to promote synergism of the raw materials; and the prepared clean vacuum pump oil has excellent heat stability and oxidation stability, can ensure a vacuum pump to reach a high vacuum degree and improves the service life of the vacuum pump.

Description

technical field [0001] The invention relates to the field of vacuum pump oil, in particular to a clean vacuum pump oil. Background technique [0002] As vacuum pumps are widely used in various fields such as semiconductor production, solar cells, aircraft, automobiles, and optoelectronics, people have higher and higher requirements for vacuum pumps, which require high thermal stability and high vacuum levels. Vacuum pump oil is a kind of vacuum pump oil specially developed for vacuum pumps on vacuum equipment. At present, conventional vacuum pump oils have poor thermal stability and oxidation stability, making it difficult to ensure high vacuum and prolong the life of the pump. [0003] In order to overcome the defects of the existing vacuum pump oil, it is necessary to develop a vacuum pump oil with excellent thermal stability, oxidation stability and self-cleaning ability, so as to ensure the high vacuum degree of the vacuum pump and improve the service life of the vacuum...
