Abstract

The invention provides a lubricating grease composition for a speed reducer clutch of a washing machine. The lubricating grease composition is formed by selecting lithium calcium metal soap as a thickening agent and adding a tackifier and other additives. The lubricating grease composition specifically comprises the following components in percentage by weight: 55-85 percent of base oil, 8-25 percent of a thickening agent and 4-20 percent of additives. A preparation method comprises the following steps: adding fatty acids, alkali and water into 30-60 percent of base oil, mixing, heating to 80-100 DEG C, raising the temperature to 90-185 DEG C to react for 2-4 hours and then raising the temperature to 205-225 DEG C, and keeping a constant temperature for 2-10 minutes; adding 10-30 percent of base oil, quenching, uniformly stirring and then quickly treating through a three-roller machine; after returning to a tank, adding an anti-rust agent, tackifier raw glue pre-dissolved with 10-55 percent of base oil in advance and stirring for 2-4 hours at a high speed to obtain a required product. The lubricating grease composition provided by the invention can meet the lubrication requirementsof the speed reducer clutch of the washing machine, improve the status quo of grease leakage of the clutch of the washing machine and ensure the service life of the washing machine.

Description

technical field [0001] The invention relates to a lubricating grease composition, more precisely, a lubricating grease applied to the clutch of a washing machine reducer and a preparation method thereof. The preparation process is simple, and it has excellent mechanical stability, adhesion, compatibility, and high and low temperature performance. It can meet the lubrication and protection of the washing machine reducer clutch, ensure that the washing machine does not lose grease during operation, can operate normally in high and low temperature environments, and does not produce noise, ensuring the service life of the washing machine. Background technique [0002] With the development of electronic technology and the improvement of people's living standards, washing machines have developed rapidly, with more and more product types and models, and have become an indispensable electrical product in people's lives. [0003] The clutch is the main component of the fully automati...
