A kind of mildew-proof lubricating grease for precision instrument and preparation method thereof

Abstract

The invention provides an anti-molding lubricating grease for precise instruments and a preparation method of the anti-molding lubricating grease. The lubricating grease is prepared from polyethylene glycol 800, glacial acetic acid, alkyl ether ammonium sulfate, trichloro hydroxydiphenyl ether, fatty alcohol-polyoxyethylene ether, organic silicon, zinc naphthenate, kaolin, sodium allysulfonate, quaternary ammonium salt, an antioxidant and 95% ethanol. The preparation method comprises the following steps: firstly, mixing polyethylene glycol 800, glacial acetic acid, alkyl ether ammonium sulfate, trichloro hydroxydiphenyl ether and fatty alcohol-polyoxyethylene ether, thereby obtaining a mixture I; secondly, adding organic silicon, zinc naphthenate, kaolin and sodium allysulfonate into the 95% ethanol, thereby obtaining a mixture II; finally mixing the mixture I and the mixture II, and further adding quaternary ammonium salt and the antioxidant, thereby obtaining the anti-molding lubricating grease. The anti-molding lubricating grease can effectively inhibit microorganism growth at lubricated and sealed parts of the precise instruments, and the use property of the precise instruments is ensured.

Description

technical field [0001] The invention belongs to the technical field of mildew-resistant lubricants, and in particular relates to a mildew-resistant grease for precision instruments and a preparation method thereof. Background technique [0002] Grease, commonly known as medium oil or butter, is a thick, greasy semi-solid. It is used in the friction part of machinery to lubricate and seal, and is also used on metal surfaces to fill gaps and prevent rust. It is mainly formulated with mineral oil and thickener. According to the thickener, it can be divided into two types: soap-based grease and non-soap-based grease. Lithium, sodium, calcium, aluminum, zinc and other metal soaps are commonly used as thickeners for soap base fats, as well as potassium, barium, lead, manganese and other metal soaps. Graphite, carbon black, asbestos, etc. are used as thickeners for non-soap-based fats. According to the use, it can be divided into two types: general grease and special grease. Th...

Problems solved by technology

[0004] During the assembly process of precision instruments, lubricating grease is often used to lubricate and seal the friction parts of the product, but some organic raw materials or their decomposition products used to make lubricating grease can provide nutrients for the growth of mold, so the parts where the instrument uses lubricating grease are prone to Mildew, sometimes the volatilization of mold secretions will also fog up the optical glass, which will reduce the performance of the product or even make the product unusable
