Problems solved by technology

[0003] However, the sealing and waterproof performance of the conventional solid grease with extrusion wear resistance is relatively poor, and the grease is easily oxidized and denatured at high temperature due to structural movement friction, so the grease needs to be replaced after a period of use. Maintain the equipment
The overall performance of this solid grease still needs to be improved

Abstract

The invention belongs to the technical field of lubrication grease and specifically relates to solid-lubrication protection grease applied to a mechanical telescopic structure. The lubrication protection grease is prepared from the ingredients of base grease, solid-lubrication base grease, molybdenum disulfide, micro-powder graphite, lead dibutyl dithiocarbamate, crystalline flake graphite, a thickening agent, an extreme-pressure anti-wear reagent, an antioxidant and a structure stabilizer, wherein the base grease is hydrocarbon mineral oil or synthetic oil, and the solid-lubrication base grease contains one or more of compound calcium-based grease, lithium-based grease, aluminum-based grease, polyurea lubricating grease and compound barium-based grease. The lubrication grease can improveevenness and stability of materials by high-temperature reaction and ultrasonic dispersion treatment. The lubrication protection grease has the advantages of good lubrication, pressure-resistant and anti-wear performance, good high-temperature-resistant, antioxidant and sealing waterproof effects and very excellent comprehensive performance.

Description

technical field [0001] The invention belongs to the technical field of lubricating grease, and in particular relates to a solid lubricating and protective grease for mechanical telescopic structures. Background technique [0002] There are many mechanical telescopic structures in construction machinery, such as oil cylinders in hydraulic transmission structures, push-pull rods on construction machinery, etc. These mechanical telescopic structures need to move frequently during work, so they need to be lubricated to prevent parts in the structure Wear during exercise. Since these mechanical parts are subjected to relatively high pressure during movement, the use of grease often chooses solid grease with better pressure resistance. [0003] However, the sealing and waterproof performance of the conventional solid grease with extrusion wear resistance is relatively poor, and the grease is easily oxidized and denatured at high temperature due to structural movement friction, so...
