Abstract

The invention discloses flame-retardant lubricating grease, which is prepared from the following raw materials in parts by weight: 70 to 95 parts of base oil, 5 to 15 parts of a thickening agent, 2 to 10 parts of a peptizing agent, 0.5 to 5 parts of a flame retardant, 50 to 100 parts of fatty acid calcium soap, 1 to 10 parts of a filling agent, 0.2 to 1 part of an antirust agent, 0.2 to 1 part of an antioxidant and 1 to 10 parts of silicon dioxide micro powder. The base oil is one of ester oil, silicone oil and polymer-olefin oil; and the thickening agent is a fatty acid metal salt or a non-soap-based thickening agent. According to the flame-retardant lubricating grease and the preparation method thereof, the water resistance and the heat resistance of the lubricating grease are enhanced by adding the thickening agent, the lubricating grease has flame-retardant, antirust and antioxidant properties by adding the flame retardant, the antirust agent and the antioxidant, and the loss resistance and the lubrication enhancement capability of the lubricating grease can be improved by adding the filling agent. By adding the silicon dioxide micro powder, the lubricating grease has excellent properties of high temperature resistance, acid and alkali corrosion resistance and high insulation.

Description

technical field [0001] The invention relates to the technical field of lubricating grease preparation, in particular to a flame-retardant lubricating grease and a preparation method thereof. Background technique [0002] The use of flame-retardant materials to prevent and reduce fires has attracted more and more attention from our country, especially in underground coal mines, subways, metallurgy and other industries. Others such as mining wire and cable, transport tape, and belt conveyor rollers for coal mines are gradually required to use flame-retardant materials, and technical standards have been formulated. my country's coal industry formulated the standard for belt conveyor rollers in 2006. , The non-metallic idler cylinder and buffer idler apron stipulate the technical conditions for flame retardant performance, but the grease used has not yet stipulated the flame retardant requirements. However, it is understood that my country's coal mine safety department requires t...
