Abstract

The invention discloses chain anti-rust lubricating grease. According to the scheme, the lubricating grease comprises, by mass, 44.0-65.0% of base oil, 10.0-12.0% of solid paraffin, 3.0-5.0% of petroleum barium sulfonate, 2.0-3.0% of barium dinonyl napthalene sulphonate, 0-5.0% of sorbitan mono-oleic acid esters and 0-40.0% of polyisobutene. According to the technical scheme, the base oil mainly has a lubricating effect, the polyisobutene increases viscosity of the lubricating grease, and the solid paraffin serves as a carrier of the base oil; the special additives including the petroleum barium sulfonate, barium dinonyl napthalene sulphonate and sorbitan mono-oleic acid esters are added, wherein the petroleum barium sulfonate and barium dinonyl napthalene sulphonate mainly have anti-rust and oxidation-resistant effects, the sorbitan mono-oleic acid esters change the surface tension of the lubricating grease, and therefore the lubricating grease can be evenly attached to the surface of a chain.

Description

technical field [0001] The invention relates to a special lubricating grease for mechanical chains, in particular to a chain antirust lubricating grease and a preparation method thereof. Background technique [0002] Many motorcycles and agricultural machinery chains mainly use ordinary antirust oil or ordinary antirust grease as the antirust treatment before the chain leaves the factory. The main problems are that the oil has poor adhesion and lubricating performance on the motorcycle chain. Well, when the motorcycle is running, the grease smeared on the chain is quickly thrown out by high-speed centrifugal force. As a result, the chain is often short of oil during actual use and is in a state of dry friction. The chain is severely worn, which can easily cause the chain to elongate, produce abnormal noise, and even fail. Greases are thick, greasy semi-solids. It is used in the friction part of the machine to lubricate and seal. It is also used on metal surfaces to fill g...
