Abstract

The invention discloses a high-speed low-noise bearing grease and a preparation method thereof. The bearing grease comprises the following components in percentage by weight: 25-30% of paraffin oil, 20-30% of naphthenic oil, 30-40% of alkyl diphenyl ether, 3-4% of 12-hydroxystearic acid, 2-3.5% of zinc laurate, 1-1.5% of molybdenum disulfide, 2-3% of zinc phosphorodithioate, 0.5-1% of octylbutyl diphenylamine and 1-2.5% of benzotriazole fatty acid ammonium salt. The bearing grease has the advantages of high carrying capacity, favorable antifriction property and favorable noise reduction property, and can effectively adapt to the occasions with high requirements for high speed and low noise. The preparation method comprises the following steps: a. heating and stirring base oil in a reaction kettle; b. adding a thickener into the reaction kettle, and heating and stirring; c. adding additives into the reaction kettle, and cooling and stirring; and d. when the temperature drops to 40 DEG C, packaging. The preparation method can effectively prepare the high-quality high-speed low-noise bearing grease.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a high-speed and low-noise bearing grease and a preparation method thereof. Background technique [0002] As a thick grease-like semi-solid, lubricating grease is widely used in friction parts of mechanical structures, among which, lubricating grease mainly plays the role of lubrication and sealing; for lubricating grease applied to metal surfaces, its main It can fill the gap and prevent rust. [0003] The vast majority of grease is used for lubrication, called anti-friction grease; anti-friction grease mainly reduces mechanical friction and prevents mechanical wear. At the same time, it also plays the role of protection against metal corrosion and the role of sealing and dustproof. [0004] For different mechanical structures, due to the differences in their working conditions and composition structures, the lubricating greases used should also be different, that i...
