Abstract

The invention discloses a lubricant for an elevator mechanism and a preparation method of the lubricant. The lubricant comprises the following components in parts by weight: 17-24 parts of erucyl amide, 8-13 parts of dodecyl sulphonate, 5-9 parts of chlorinated paraffin, 4-10 parts of phosphorodithioic acid diethyl ester, 3-7 parts of lithium base bentonite, 2-9 parts of glyceryl dilaurate, 4-11 parts of cocoanut oil fatty acid diethanolamide, 3-8 parts of sodium tripolyphosphate, 2-7 parts of sodium nitrite, 1-3 parts of antirust agent, 2-4 parts of defoaming agent and 30-40 parts of solvent. The prepared lubricant has the maximal non-seizure load of more than 637N, the antirust time of more than 60 days and lower friction coefficient, displays well antirust and lubricating performances, and is better in comprehensive performance and suitable for the elevator mechanism.

Description

technical field [0001] The invention belongs to the field of lubricants, in particular to a lubricant for a lifting mechanism and a preparation method thereof. Background technique [0002] In mechanical manufacturing, lifting mechanisms are used in many equipment or working mechanisms, which can realize the lifting movement of components to meet specific work needs. Usually, in order to make the lifting movement of parts smoother and its movement precision, lubricants are applied to the lifting mechanism to ensure good lubrication and reduce movement resistance, which can better improve the performance of the entire device. However, there are not too many special lubricants for the lifting mechanism on the market, which not only guarantee the movement accuracy of the mechanism, but also ensure good anti-rust and lubricating effects. Contents of the invention [0003] The technical problem to be solved is: in order to solve at least one of the above problems, provide a lu...
