Abstract

The invention provides a composition for forming a heat-conducting lubricant. The composition or raw materials of the composition comprise the following components in parts by weight: 100 parts of dimethyl silicone oil, 200-400 parts of aluminum oxide, 10-50 parts of zinc oxide, 5-45 parts of a lubricant, 1-10 parts of an anti-settling agent, 0.1-10 parts of inorganic salt, 0.1-10 parts of a heat stabilizer, and 0.01-5 parts of a silane coupling agent, wherein the lubricant comprises one or more of zinc stearate, calcium stearate, paraffin oil, naphthenic oil and silicone; the anti-settling agent comprises one or more of ethyl acetate, butyl acetate, xylene, normal hexane and butanol; and the inorganic salt is selected from one or more of nitrite and sulfite. By optimizing the formula, the composition provided by the invention can be used for conveniently preparing the heat-conducting lubricant, and the formed heat-conducting lubricant has excellent heat-conducting property and lubricating property at the same time.

Description

technical field [0001] The invention relates to the technical field of lubricants, in particular to a composition for forming a heat-conducting lubricant. Background technique [0002] The temperature rise and temperature distribution of high-speed rolling bearings will directly affect the working performance and service life of the bearing system. The increase in the rotational speed of the rolling bearing will lead to an increase in the heat generated by the friction of the bearing. If the heat is not dissipated in a timely and effective manner, the internal temperature of the bearing will be too high, which will cause the surface of the internal parts of the bearing to be burnt or even glued, seized and scrapped prematurely. [0003] Therefore, it is necessary to develop a multi-functional heat-conducting silicone grease mixture, which has both lubricating function and heat-conducting heat-conducting function. The application of this heat-conducting grease in the bearing ...
