Abstract
The invention discloses automobile air-conditioning compressor lubricating oil, and particularly relates to the technical field of chemical engineering lubricating oil. The ingredients of the automobile air-conditioning compressor lubricating oil comprise 5 to 60 parts of isopropyl acetate, 4 to 50 parts of castor oil, 3 to 30 parts of triethylene glycol di-n-heptanoate, 2 to 34 parts of bacteriostatic agent, 3 to 19 parts of epoxy rice bran oleic acid butyl ester, 2 to 59 parts of mineral oil, 2 to 37 parts of honey, 3 to 18 parts of carbomer, 3 to 35 parts of tween 80, 2 to 19 parts of microcrystalline cellulose, 2 to 17 parts of Arabic gum, 2 to 21 parts of garlic oil, 2 to 23 parts of ethyl 4-hydroxybenzoate alcoholic solution, 2 to 16 parts of pelargonium hortorum extract, 3 to 34 parts of peanut oil, and 3 to 16 parts of kinetin. The automobile air-conditioning compressor lubricating oil prepared by the invention is safe and non-toxic, has no off-odour, is strong in water absorption capability, and is capable of solving the archenemy, namely the humidity, of an air conditioning refrigerating system; the lubricating oil is circulated in the refrigerating system with a refrigerant, so that a moisture absorption effect is realized, friction among parts is reduced, abnormal sound generated inside a compressor is reduced, the service life of the air-conditioning compressor is prolonged, and the abrasion is reduced.
Description
Technical field: [0001] The invention relates to the technical field of chemical lubricating oil, in particular to an automotive air-conditioning compressor lubricating oil. Background technique: [0002] Automobile air conditioning device (air conditioning device) is referred to as automobile air conditioner.
