Abstract

The invention provides a graphite lubricant. The graphite lubricant comprises the following compositions in parts by weight: 20 parts-30 parts of graphite micro powder, 3 parts-10 parts of nanometer copper borate, 3 parts-8 parts of talcum powder, 2 parts-5 parts of polyoxyethylene oleyl ether, 5 parts-10 parts of molybdenum disulfide, 1 part-5 parts of sodium alkylbenzenesulphonate, 5 parts-20 parts of methyl cellulose, 4 parts-8 parts of sodium borate, 5 parts-15 parts of propanol, and 20 parts-40 parts of water. The aqueous graphite lubricant is small in environmental pollution, green, environment-friendly, wide in application temperature, good in lubricity, high in stability and low in cost.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to a graphite lubricant. Background technique [0002] Graphite lubricating oil is widely used in various types of machinery to reduce friction, protect machinery and processed parts, mainly for lubrication, cooling, rust prevention, cleaning, sealing and buffering. The graphite lubricants currently used are mostly solid or mineral oil-based media, which are unstable at high temperatures, easy to burn and decompose, and at the same time cause mechanical damage due to loss of lubricating effect at high temperatures. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a water-based graphite lubricant with good lubricating performance, high stability and wide applicable temperature range. [0004] In order to achieve the above object, the technical solution provided by the present invention is a graphite lubricant, and the compo...
