Abstract

The invention discloses complex titanium base grease and a method for preparing the same, which relates to grease and a method for preparing the same. The invention solves the problems that: the prior grease causes the vibration velocity of bearings to be unsteady, and has noises. The grease is prepared by base oil, thickening agent and additive. The method is as follows: 1. the base oil, the thickening agent and the additive are weighed; 2. the weighed thickening agent is mixed and stirred with one third of the base oil, the mixture is subject to the temperature rise and then heat preservation; 3. the mixture treated by the step 2 is subject to the temperature rise, and heat preservation for 0.5 to 5 minutes at a stirring speed of between 15 and 60r/m; 4. the mixture treated by the step three 3 is added with the remaining two-third base oil and is stirred and cooled, and then the additive is added into the mixture to grind to prepare the grease. With the grease, the vibration velocity of the bearings is as follows: the low frequency velocity is less than or equal to 30 mu m/s, the intermediate frequency velocity is less than or equal to 19 mu m/s, and the high frequency velocity is less than or equal to 28 mu m/s; and the vibration velocity is steady, and no noise exists.

Description

technology field. [0001] The invention relates to a lubricating grease and a preparation method thereof. Background technique [0002] With the development of electromechanical products, the requirements for the silent life of rolling bearings in electromechanical products such as air conditioners and refrigerators are getting higher and higher. While the service conditions of bearings are becoming more and more severe, the requirements for lubricating grease are also getting higher and higher, mainly in terms of long life, high / low temperature performance, low noise and other characteristics. The noise characteristics of lubricating grease and the development of low-noise grease have become popular research directions. [0003] The patent No. EP 0765374B1 discloses a low-noise lithium complex grease whose dropping point can reach 270° C. (ASTM D566), including lithium complex soap accounting for 2 to 30 wt% of the grease weight, Accounting for 0.1-10 wt% polyalkylsuccinic...
