Abstract

The invention relates to lubricating grease for a crane jib. The lubricating grease comprises a thickening agent, base oil and an additive. The lubricating grease is characterized by comprising raw materials in parts by weight as follows: 18-22 parts of the thickening agent, 90-100 parts of the base oil and 3-5 parts of the additive, wherein the thickening agent is a mixture of bentonite, stearic acid, amide and gelatin; the base oil is a mixture of pentaerythritol, trimethyl citrate and castor oil; the additive is a mixture of resin, carboxymethyl cellulose and polydimethylsiloxane. The lubricating grease takes the mixture of pentaerythritol, trimethyl citrate and castor oil as the base oil, so that the lubricating grease is rich in source and good in lubricating effect; the lubricating grease takes the mixture of the bentonite, the stearic acid, the amide and the gelatin as the thickening agent, and accordingly, the viscosity of the lubricating grease is guaranteed; the resin, the carboxymethyl cellulose and the polydimethylsiloxane are added, then the wear resistance of the lubricating grease can be improved, a layer of adsorption film can be formed on the surface of the crane jib, and the service life of the lubricating grease is prolonged.

Description

technical field [0001] The invention relates to a lubricating grease for a crane arm, belonging to the technical field of industrial chemicals. Background technique [0002] Grease is a kind of lubricant with non-Newtonian fluid characteristics between semi-fluid and solid, which is obtained by dispersing one or more thickeners in one or more liquid lubricants. The basic characteristics of grease are that it has a certain shape, is easy to adhere, and has lower fluidity than the corresponding base oil. Grease is used in the friction parts of machinery to lubricate and seal. [0003] With the expansion of production scale and the improvement of automation, cranes, as important equipment for material handling, play an increasingly important role in the modern production process, and their applications are becoming wider and wider, and the requirements for cranes are also getting higher and higher. The rapid development of science and technology has promoted the improvement...
