Abstract

The invention relates to lubricating grease for changing the anti-rust effect. The lubricating grease comprises lithium soap thickening agents, base oil, antioxidants, anti-rust agents and viscosifiers and solves the problems that steel and iron are easy to rust under special conditions, and thus equipment can not be used and the resources are wasted. The lubricating grease has the beneficial effect the anti-rust effect of the lubricating grease is improved through improving the kinematic viscosity of the base oil and adding the proper antioxidants, anti-rust agents and viscosifiers to the lubricating grease. Through the damp heat test and the salt spray test in the lubricating analysis evaluation, the anti-rust effect in the evaluation results is greatly improved through being compared with the anti-rust effect of the ordinary lubricating grease. After the actual use, the equipment can still maintain a good state under the influence of external oxygen, water and acid media.

Description

[0001] technical field [0002] The invention relates to a kind of lubricating grease which can change the antirust effect. Specifically, it is a kind of lubricating grease which further improves the antirust effect and protects steel from rusting on the basis of general lubricating grease. Background technique [0003] Steel corrodes and rusts due to the chemical or electrochemical action of environmental media (oxygen, water, acidic substances, etc.). Rust is the enemy of steel. It is estimated that about 1 / 4 of the steel produced in the world every year is corroded, which causes a great waste of resources. Usually lubricating grease is applied on the equipment to form a thick covering oil film to block oxygen, water, and corrosive media, and the steel reacts to form ferroferric oxide (rust), preventing the change of many excellent properties that steel should have. Under normal conditions of use, ordinary lubricating grease can have a certain anti-rust effect. However,...
