Embodiment 1

[0017] A method for preparing a heat-conducting, high-temperature-resistant and durable lubricant, comprising the following steps: 1. Weighing each raw material according to a predetermined ratio, adding and melting 1-cyanobenzocyclobutene and terephthaloyl chloride monomer Form a prepolymer. After the prepolymer cools down, add an active diluent to keep it warm. After cooling, add a solution containing a catalyst, mix well, and vacuum evaporate the solvent that dissolves the catalyst. The specific steps are to prepare 1-cyanobenzocyclobutene After heating to 150°C, slowly add terephthaloyl dichloride monomer within 1 hour, keep warm at this temperature for 3 hours, and the two undergo addition melt copolymerization until the system is completely dissolved and uniform to obtain a prepolymer. The phthaloyl chloride monomer is, after the temperature of the prepolymer is lowered to 100°C within 30 minutes, a prepolymer reactive diluent is added to obtain a diluted prepolymer, whic...

Abstract

The invention discloses a preparation method of a heat-conducting, high-temperature-resistant and durable lubricant. The preparation method comprises the following steps: carrying out addition melting copolymerization on 1-cyanobenzocyclobutene and a paraphthaloyl chloride monomer to form a prepolymer, preparing a borosiloxane ferrocene prepolymer from dimethylchlorosilane and dicyclopentadiene, and reasonably matching the components to obtain the heat-conducting, high-temperature-resistant and durable lubricant; in addition, a plurality of inorganic components, a clean dispersing agent, an antioxidant and polyadamantane-1,3-diformyl-m-phenylenediamine are compounded for blending modification; therefore, the lubricant has a synergistic lubricating effect and excellent lubricating performance, the lubricating performance reaches or exceeds the same level of a graphite type product, and the lubricant is excellent in miscellaneous oil resistance and long in service life. The lubricant is green and environment-friendly, and is a high-performance environment-friendly hot forging working fluid. The lubricant has the advantages of low raw material consumption, low pollution, long effective lubricating time, low labor intensity, long service life of equipment parts and high temperature resistance.

Description

technical field [0001] The invention relates to the technical field of lubricants, in particular to a preparation method of a thermally conductive, high temperature resistant and durable lubricant. Background technique [0002] Today, there are more and more machinery and equipment that need to work at high temperature, so people are looking for high temperature resistant lubricants everywhere to ensure the normal operation of such machinery and equipment. Especially in aerospace technology and atomic energy industry, only high temperature resistant lubricating materials can achieve good lubricating effect under the conditions of ultra-high temperature, ultra-low temperature, high vacuum, strong radiation, and ultra-high pressure. In the past, mineral oil lubricants were used. It is easy to decompose to produce gas and volatile dust, causing fabric pollution and air pollution, and the service life is not long, it needs to be stopped for about 1-2 weeks to replace the lubrica...
