Abstract

The invention discloses rust preventive lubricating oil for elevators, prepared from, by weight, 1-2% of polyisobutylene, 2-5% of bis-salicylidene diamine, 2-3% of barium salt of phosphosulfurized polyisobutylene, 1-2% of oleic acid glycol monoester, 0.5-2% of sodium thiophosphate dodecahydrate salt, 1-1.5% of chloroparaffin, 1-3% of alkylbenzene sulfonate magnesium, 1-3% of methyl benzoate, 1-2.5% of isodehydrocostus lactone and residual base oil. The invention further discloses preparing method for rust preventive lubricating oil for elevators. The rust preventive lubricating oil for elevators and preparing method thereof can resist wearing, reduce wearing, prevent rust, resist oxidation, and have high force of adhesion and penetration by being applied.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an antirust lubricating oil for elevators. Background technique [0002] With the popularity of elevators, elevators are used in more and more different occasions. The demand for both elevators and escalators is also increasing. Elevator safety and daily maintenance are becoming more and more important. One of the routine items in the daily maintenance of elevators is to check whether many parts of the elevator need to be lubricated, such as traction gearboxes, wire ropes, guide rails, hydraulic buffers and car door machines. The special lubricating oil for elevators in the prior art tends to harden, crack or even fall off after being used for a period of time, causing the elevator to generate greater friction during operation, which not only forms greater resistance, but also tends to wear parts, reducing The service life of the elevator is not conducive to the safe and stable operatio...
