Grinder gear lubricating grease and preparation method thereof

Abstract

The invention discloses grinder gear lubricating grease and a preparation method thereof. The grinder gear lubricating grease is prepared from components in parts by weight as follows: 70-85 parts of base oil, 10-18 parts of polypropylene wax, 5-15 parts of ammonium sulfate, 3-5 parts of glycidyl triethyl ammonium chloride, 0.8-2 parts of triethanolamine salt, 0.5-2 parts of a coupling agent and 0.8-1 part of an antioxidant. The method comprises steps as follows: (1), weighing 10-18 parts of the polypropylene wax, 5-15 parts of the ammonium sulfate, 3-5 parts of the glycidyl triethyl ammonium chloride, 0.8-2 parts of the triethanolamine salt, 0.5-2 parts of the coupling agent and 0.8-1 part of the antioxidant, heating the mixture to the temperature of 150-200 DEG C, and stirring the mixture for 1-2 h for cooling; (2), adding 70-85 parts of the base oil to a product in step (1), mechanically stirring the mixture for 0.5-1 h, and repeatedly grinding the mixture for 2-4 h to obtain the grinder gear lubricating grease.

Description

technical field [0001] The invention belongs to the field of lubricating grease, in particular to a grinder gear lubricating grease and a preparation method thereof. Background technique [0002] Grease is a semi-fluid and semi-solid substance with a certain viscosity. On the lubricating surface, it can prevent fluid or solid particles from leaking from adjacent joint surfaces and prevent external impurities such as dust and moisture from invading the interior of the machine and equipment, thereby protecting the equipment. works well. [0003] The traditional grease processing technology is: add calcium hydroxide (or sodium, lithium, aluminum, barium, etc.) to animal and vegetable oils or fatty acids to prepare metal soap as a thickener or use organic or inorganic thickeners, add mineral oil or synthetic Oil is processed and thickened, mainly by storing mineral oil or synthetic oil in the framework of the thickener, and under the action of pressure and temperature during e...

Problems solved by technology

[0003] The traditional grease processing technology is: add calcium hydroxide (or sodium, lithium, aluminum, barium, etc.) to animal and vegetable oils or fatty acids to prepare metal soap as a thickener or use organic or inorganic thickeners, add mineral oil or synthetic Oil is processed and thickened, mainly by storing mineral oil or synthetic oil in the framework of the thickener, and under the action of pressure and temperature during exercise, the oil stored in the thickener escapes, It acts as a lubricant and exhibits paste-like physical properties at normal temperature and pressure. However, after a period of time, the oil will naturally escape and separate from the frame formed by the thickener, which will affect the use. Under some extreme conditions such as high temperature and high pressure, due to The oil in the frame escapes too quickly, causing dryness, and cannot maintain the lubrication effect for a long time, requiring frequent grease changes, resulting in equipment downtime and manpower waste
