Abstract

The invention relates to the technical field of lubricating grease and particularly relates to special lubricating grease for a telescope and a preparation process thereof. The lubricating grease comprises the following components in percentage by weight: 60-85% of base oil, 15-30% of a thickener, 1-5% of phenyl-beta-naphthylamine, 5-10% of sulfurized cottonseed oil, 0.1-2% of lanolin magnesium soap and 0.1-1% of benzotriazole. Compared with the prior art, the special lubricating grease for the telescope has the beneficial effects of excellent low temperature property and oxidation stability and low evaporation loss, excellent shear stability and colloidal stability and small oil diffusion, excellent abrasion resistance and lubricity and good protective property against metals, and good water resistance and corrosion resistance and is compatible with a majority of plastics and a rubber body.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a special lubricating grease formula for telescopes and a preparation process thereof. Background technique [0002] As a precision instrument, telescopes have been very popular in civil and industrial fields. The sliding and rotating parts around the lens of precision optical instruments and the lubrication and sealing of friction parts close to the surface meet the requirements of low temperature resistance, mildew resistance, diffusion resistance, and long life. Lubrication also puts forward higher requirements. The lubricating grease currently available on the market has excellent anti-wear and lubricating properties, and has good protective properties for metals; good water resistance and corrosion resistance, and is compatible with most plastic and rubber bodies. However, the low temperature performance and oxidation stability cannot meet the requirements. In v...
