Abstract

The invention discloses a preparation method of lubricating grease, and belongs to the field of lubricant oil. The preparation method disclosed by the invention comprises the following steps: inducingphenyl, dimethyl dichlorosilane and the like as raw materials by dichloromethylphenylsilane and trifluoropropyl methyl dichlorosilane, so as to prepare mixed type oxosilane; synthesizing methyl dichlorosilane into chlorine-containing oxosilane and then mixing; adding 1-dodecylene; performing catalysis through chloroplatinic acid; further synthesizing long-chain alkyl modified oxosilane hybrid ring body through silicon-hydrogen addition reaction with high reaction activity; then synthesizing lubricating grease matrix oil through ring-opening reaction. By long-chain alkyl, the heat stability and the compatibility with an organic matter can be improved; by introduction of the long-chain alkyl, silicon oil can be compounded with naphthenic rubber base oil preferably; because trifluoropropyl is introduced for modification, a metal compound solid film is formed at a high temperature, contact between metal and another metal is reduced, and sintering between metal surfaces is prevented, so that the lubricity at a high temperature is improved, and the lubricating grease is difficultly lost in a high temperature state.

Description

technical field [0001] The invention belongs to the field of lubricating oil, and in particular relates to a preparation method of lubricating grease. Background technique [0002] Grease, a thick, greasy semi-solid. It is used in the friction part of the machine to lubricate and seal. It is also used on metal surfaces to fill voids and prevent rust. It is mainly prepared from mineral oil (or synthetic lubricating oil) and thickener. According to the thickener, it can be divided into two types: soap-based grease and non-soap-based grease. The function of grease is mainly to lubricate, protect and seal. The vast majority of greases are used for lubrication and are called antifriction greases. Anti-friction grease mainly plays the role of reducing mechanical friction and preventing mechanical wear. At the same time, it also plays a protective role against metal corrosion and a sealing and dustproof function. There are some greases that are primarily used to prevent rust...
