Abstract

The invention discloses a grease composition and preparation method thereof, especially relates to a noise reduction gear grease composition and preparation method thereof. The grease composition contains base oil, EP rubbers, densifier, anti-oxidant and anti-wear reagent at extreme pressure, and when the base oil amount is 100 parts (by weight), the EP rubbers amount is 2-25 parts (by weight), the densifier amount is 4-20 parts (by weight), and the anti-oxidant is 1-2.5 parts (by weight) and the anti-wear reagent at extreme pressure amount is 1-5 parts (by weight). The purpose of the present invention is to provide a grease composition with excellent noise reduction, shearing resistance, low temperature resistance performances and preparation technology of the grease composition, and the invention solves the problems of severe wearing, large noise, short service life or the like caused by insufficient lubricating oil function in the mechanical industry.

Description

technical field [0001] The invention relates to a lubricating grease composition and a preparation method thereof, in particular to a noise reduction gear lubricating grease composition and a preparation method thereof. Background technique [0002] With the rapid development of industry, various industries have put forward more stringent requirements for product comfort, durability, product quality and other indicators. Especially in the machinery industry, the requirements for parts and components are even higher. Due to the processing error or insufficient assembly precision of the friction parts and accessories of many products, and the improper use of lubricating grease and other factors, it often leads to accelerated wear and excessive noise of mechanical parts. , thus affecting the normal function of mechanical equipment, which in turn affects the quality and final service life of the product. The processing error or assembly precision of parts is closely related to ...
