Abstract

The invention discloses precise polymer special lubricating grease which is characterized by comprising the following components in parts by weight: 63-82 parts of base oil, 7-10 parts of a thickeningagent, 5-10 parts of lithium hydroxide (LiOH. H2O), 2-4 parts of colloidal graphite, 3-5 parts of nanoscale light calcium carbonate, 2-5 parts of polyisobutene, 5-8 parts of dimer acid, 3-5 parts ofborate and 1-3 parts of cellulose. The special lubricating grease is resistant to high temperature, water spraying and extreme pressure, and can effectively protect a wheel belt and a gear, so that the service life is prolonged, and the use cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of lubricating grease, and in particular relates to a precision polymer special lubricating grease and a preparation method thereof. Background technique [0002] In open gears, tires and other parts, it is often necessary to use lubricating grease with characteristics such as rainproof, dustproof, shear resistance, and high temperature resistance. The traditional lubrication method of this part is immersion lubrication or spray lubrication, and traditional lubricating oil is also used. This method not only requires frequent maintenance, but also the amount of gear wear can reach 2.87mm per year. In addition, under high temperature conditions, open gears and tires often suffer from problems such as lubrication failure, trapezoidal lines on the tire surface, large vibrations, and cracked teeth. Contents of the invention [0003] The task of the present invention is to provide a precision polymer special l...
