Abstract

The invention relates to a preparation method of lubricating oil containing fluorine, comprising the following steps: taking 34-72 parts by weight of perfluoro alkyl iodide or perfluoro alkyl ethyl iodide and 5-13 parts by weight of olefine monomer as main ingredients, adding 0.8-1.5 parts by weight of initiator, and carrying out synthetic reaction at the temperature of 40-120 DEG C for 0.5-4 hours; adding 1-12 parts by weight of catalyst, 30-65 parts by weight of acetic acid and 38-75 parts by weight of alcohol solvent after reaction, and reacting continuously at the temperature of 40-120 DEG C for 1-4 hours; filtering, removing the solvent, washing and dewatering, thus obtaining the fluorine containing lubricating oil. Compared with perfluoropolyether, the invention has the advantages that process is simple, service time is long, cost is reduced by 30%, thermal stability is good, viscosity thereof is slightly changed at the temperature of 220-280 DEG C, mechanical abrasion is reduced by more than 90%, cost performance is high, no pollution is produced, adaptive limit temperature range is wide, the adaptive limit temperate ranges from minus 40 to 280 DEG C, and the lubricating oil containing fluorine has small possibility of oxidation, thus being applicable to inflammable and explosive places, and the obtained fluorine containing lubricating oil can save fuel oil by more than12%, thus achieving obvious energy conservation effect.

Description

technical field [0001] The invention belongs to a preparation method of lubricating oil, in particular to a preparation method of fluorine-containing lubricating oil which can save more than 12% of fuel and reduce mechanical wear by 90%. Background technique [0002] With the rapid development of industry, especially the development of aerospace technology, petrochemical and other enterprises in recent years, the rapid development of lubrication technology has put forward higher requirements for lubricating oil. Ordinary hydrogenated lubricating oil and synthetic lubricating oil have short service life, high fuel consumption, waste of energy, and are not environmentally friendly. In addition, they cannot be used in the field of high and low temperature resistance, flammable and explosive equipment. Perfluorinated oil can solve the above problems, but the cost of existing perfluorinated oil is high and its application is limited. Contents of the invention [0003] The tech...
