Abstract

The invention discloses low-noise lubricating grease and a preparation method thereof. The lubricating grease consists of base oil, a thickener and an additive, wherein the thickener accounts for 12-14% by weight of the base oil and the additive accounts for 1.6-2.5% by weight of the base oil. The base oil is a mixture of silicon oil, pentaerythritol, alkylbenzene and poly-alpha-olefin oil, the thickener is a mixture of paraffin, asbestos and ozocerite, and the additive is a mixture of dialkyl dithiophosphate, dodecenylsuccinic acid, zinc naphthenate, di-tert-butyl phenol and polyisobutene. The lubricating grease disclosed by the invention is simple in preparation method. By using the mixture of silicon oil, pentaerythritol, alkylbenzene and poly-alpha-olefin oil as the base oil, the lubricating grease is good in lubricating effect. By using paraffin, asbestos and ozocerite as the thickener, the noise of the lubricating grease is reduced. By adding dialkyl dithiophosphate, dodecenylsuccinic acid, zinc naphthenate, di-tert-butyl phenol and polyisobutene, the resistance to oxidation and wear resistance of the lubricating grease are improved.

Description

technical field [0001] The invention relates to a low-noise lubricating grease and a preparation method thereof, 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] The service life of lubricating grease refers to the ability of lubricating grease to keep the structure from being damaged and maintain the performance of lubricating grease under certain temperature, load and rotational speed. The production process of low-noise grease is relatively complicated, and there are special requirements for base oil viscosity, fiber struct...
