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.
