Abstract

The invention discloses a preparation method of highly heatproof lubricating grease. The preparation method comprises the following steps that (1) organic acid is prepared and mixed; (2) a saponifiedsubstance is prepared, and rapidly cooled; (3) a mediate mixing agent is prepared; (4) preliminarily prepared lubricating grease is prepared; and (5) the highly heatproof lubricating grease is prepared. The invention provides the preparation method of the highly heatproof lubricating grease, the heatproof ability of the lubricating grease is greatly improved, the probability of spontaneous combustion of the lubricating grease in the using process is lowered, and the using safety of the lubricating grease is greatly enhanced.

Description

technical field [0001] The invention belongs to the field of lubricating grease preparation for mechanical equipment, in particular to a method for preparing lubricating grease with high heat resistance. Background technique [0002] 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 the role of protecting against metal corrosion and sealing and dustproof. Grease is mostly a semi-solid substance with unique fluidity. The working principle of grease is that the thickener keeps the oil in the position that needs to be lubricated, and when there is a load, the thickener releases the oil to lubricate. At room temperature and at rest, it acts like a solid, retains its shape without flowing, and adheres to metal without slipping. At high...
