Abstract

The invention relates to lubricating grease for a guide rail lead screw mechanism of a dust-free room in order to effectively solve the problem that the working stability and service life of the guide rail lead screw mechanism are influenced because of high cost, high dust content and low service performance of the existing product. The lubricating grease is prepared from the following components in percentage by weight: 80-90% of composite base oil, 7-12% of a thickening agent, 2.0-5.0% of an antiwear agent, 0.3-1.0% of an antioxidant, 0.05-0.1% of an antirust agent, 0.1-0.5% of an oiliness solvent and 0.05-0.1% of a metal passivator and is prepared by using a method comprising the following steps of firstly, mixing all the raw material components together, and refining; and then, stirring, circularly cooling to the room temperature, grinding, and carrying out vacuum degassing. The lubricating grease is scientific and reasonable in component, easy to produce and prepare, good in comprehensive performance, low in cost, extremely low in dust content, excellent in oxidation stability, favorable in lubricating property, compression resistance, wear resistance, rust prevention and corrosion resistance and capable of improving the driving stability and reliability.

Description

technical field [0001] The invention relates to chemical industry, in particular to a lubricating grease for a clean room guide rail screw mechanism. Background technique [0002] With the popularization of modern automated production lines, the application of manipulators is becoming more and more common. The guide rail screw drive mechanism is an important component of the manipulator. The performance of the lubricating material used in it is directly related to the stability, reliability and accuracy of the manipulator. In the production process of most high-tech enterprises, the manipulator is required to work under the working conditions of the clean room. The clean room is a place for manufacturing ultra-precision products. It is necessary to ensure that the products are produced and manufactured in a good environment, and the temperature, humidity and cleanliness of the gas in the product production environment are high. [0003] However, enterprises urgently require...
