Abstract

The invention relates to the technical field of lubricating grease and in particular relates to a formula of lubricating grease specially used for a mine car and a preparation method of the lubricating grease specially used for the mine car. The lubricating grease specially used for the mine car comprises the following components in percentage by weight: 60-85% of base oil, 15-30% of a thickening agent, 1-5% of antioxidant, 5-10% of sulfurized alkene cotton seed oil, 0.1-2% of sorbitol monooleate and 0.1-1% of benzotriazole. Compared with the prior art, the lubricating grease specially used for the mine car has the beneficial effects that firstly lubricating property and carrying capacity are excellent, and service life of the mine car is prolonged; secondly, water resistance and anticorrosion protection are excellent, and harsh working condition can be adapted; and thirdly, using temperature range is wider, and the lubricating grease can not be frequently replaced.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a special lubricating grease formula for mining vehicles and a preparation process thereof. Background technique [0002] Mining cars are narrow-gauge railway transport vehicles for transporting bulk materials such as coal, ore and waste rocks in mines. Generally, they must be pulled by locomotives or winches. The working environment is generally harsh and the workload is heavy. The hub bearings of mine cars and the gear motors of traction motor bearings are very worn. Ordinary lubricating grease can lubricate the mine car, slow down wear and improve the life of the mine car, but its corrosion resistance and water resistance are average. To solve the above problems, it is necessary to provide a new type of special lubricating grease for mine cars to improve Corrosion and water resistance, wider temperature range. Contents of the invention [0003] The object of th...
