Gear grease prepared from petrolatum

Abstract

The invention discloses gear grease prepared from petrolatum and relates to the technical field of petrochemical engineering. The gear grease is prepared from, by weight, 40-50 parts of petrolatum, 10-15 parts of linseed oil, 10-15 parts of hydroxyethyl cellulose, 8-13 parts of carbomer resin, 6-10 parts of attapulgite, 6-10 parts of polyoxyethylene lauryl ether, 5-8 parts of cetanol, 5-8 parts of styrene-butadiene rubber, 4-6 parts of gelatin, 3-5 parts of nanosized ceramic powder, 3-5 parts of rust-proof auxiliaries, 1-2 parts of amine oxide, 10-15 parts of propanediol butyl ether and 20-25 parts of residual oil. The gear grease prepared from the petrolatum has the advantages that the gear grease is moderate in viscosity and can quickly form a protecting film layer on the surface after being applied to a gear so as to play a role in lubrication to reduce transmission resistance and improve transmission efficiency; the gear grease is stable in viscosity and high in corrosion resistance and cannot corrode the gear so as to be beneficial to prolongation of service life of the gear.

Description

Technical field: [0001] The invention relates to the technical field of petrochemical industry, in particular to a gear lubricating grease prepared from petroleum grease. Background technique: [0002] Petroleum grease, also known as wax paste, is a mixture of microcrystalline ozokerite and petroleum. General petrolatum contains 70%-80% ozokerite and 20%-30% heavy lubricating oil fractions. It is often used as a grease ingredient for some machinery, and can also be used as anti-rust oil, ointment, or as a material for the production of vaseline and ozokerite. [0003] Gears are easily damaged during work for the following reasons: First, the oil film cannot be established due to the low viscosity, low speed, and heavy load of the lubricating oil; Poor viscosity, improper viscosity, lack of oil, etc. cause different degrees of adhesive wear; third, the lubrication system is mixed with external dust and other particles, as well as internal wear debris, colloid and other impu...

Problems solved by technology

[0003] Gears are easily damaged during work for the following reasons: First, the oil film cannot be established due to the low viscosity, low speed, and heavy load of the lubricating oil; Poor viscosity, improper viscosity, lack of oil, etc. cause different degrees of adhesive wear; third, the lubrication system is mixed with external dust and other particles, as well as internal wear debris, colloid and other impurities to cause particle wear; fourth, repeated contact stress in the cycle Under the action, the surface material will be pitted, peeled and fractured; fifth, water, metal particles, chemical pollutants, and the chemical action of lubricating oil and the participation of oxygen in the lubrication system will cause corrosion and wear, etc.

Although the lubricating performance of commercially available gear grease can meet the requirements of use, the viscosity increases after a period of use, thereby increasing the transmission resistance of the gear, wearing the gear, and shortening the service life of the gear; or being oxidized during use, resulting in The oxidation products of the gears have a corrosive effect on the gears, resulting in gear failure
