Abstract

The invention discloses a low-temperature antirust oil for bearing seal. The low-temperature antirust oil comprises, by weight, 71-80 parts of No.46 hydraulic oil, 0.6-1 part of polymethacrylate, 2-3 parts of epoxy soybean oil, 7-10 parts of calcium petroleum sulfonate, 0.8-1.4 parts of lauric diethanolamide, 1-2 parts of sodium dodecyl benzene sulfonate, 2-4 parts of dodecyl dihydrogen phosphate, 0.8-2 parts of zinc dialkyl dithiophosphate, 1-2 parts of 2-methylimidazoline and 10-15 parts of a film forming assistant. The oil film of the antirust oil has he advantages of good retentivity, good low temperature fluidity, and no cold crack at a low temperature, can meet use requirements in -10DEG C or below environment, is especially suitable for the bearing seal under low temperature conditions, and has no untoward effects on bearing lubricating grease.

Description

technical field [0001] The invention mainly relates to the field of lubricating oil, in particular to a low-temperature antirust oil for bearing sealing. Background technique [0002] Anti-rust oil is made by adding lubricating oil as base oil, adding anti-rust agent and some improving additives. Generally, anti-rust oil can be divided into displacement anti-rust oil, lubricating oil type anti-rust oil, solvent dilution type anti-rust oil and so on. Among them, lubricating oil type anti-rust oil is the main anti-rust oil variety in my country. It has a wide range of applications and is mainly used for anti-rust inside machinery. It can be used for anti-rust storage and immediate lubrication after unsealing. In addition, this product can also be applied to the antirust and lubrication of the running friction working surfaces of various machines. In particular, it is widely used in the friction parts of port machinery and ship machinery, such as steel wire ropes, etc....
