Abstract

The invention discloses lubricating grease for a tubular motor and a preparation method of the lubricating grease for the tubular motor. The lubricating grease is prepared from the following raw materials in parts by weight: 45-65 parts of 20# machine oil, 20-30 parts of poly alpha-olefin, 4-8 parts of glycerol tribehenate, 5-10 parts of aluminum distearate, 3-6 parts of calcium myristate, 5-10 parts of diisooctyl maleate, 6-9 parts of sodium lauroyl sarcosine, 2-3 parts of potassium dichromate, 1.5-2.5 parts of zinc sulfate, 1-2 parts of 2-mercaptobenzothiazole, 2-4 parts of molybdenum dibutyldithiocarbamate, 10-15 parts of organobentonite, 3-5 parts of a dimerized linoleic acid copolymer and 2-3 parts of N-phenyl-2-naphthylamine. The lubricating grease disclosed by the invention has the extremely high oil film forming ability, the good noise reduction and antiwear effects, the good lubricating property and heat resistance, the excellent oxidation stability, mechanical stability and ageing resistance, and the long service life, and is applied to lubrication, friction reduction and noise reduction of the various tubular motors.

Description

technical field [0001] The invention relates to a tubular motor lubricating grease and a preparation method thereof, belonging to the technical field of lubricating grease. Background technique [0002] Grease is made from mineral oil (or synthetic lubricating oil) and a thickener. It is a thick grease-like semi-solid. It is used in the friction part of the machine to lubricate, reduce mechanical friction, and prevent mechanical wear. It also plays a protective role against metal corrosion and a sealing and dustproof function; it is also used on metal surfaces to fill gaps and prevent metal from rusting or corroding. At present, the lubricating grease used for tubular motors in the market has the disadvantages of extreme pressure and anti-wear, oxidation stability and poor vibration and noise reduction performance, resulting in poor working effect and short service life. Therefore, it is urgent to develop a vibration and noise reduction , Tubular motor grease with excellen...
