Method for antioxidant lubricating cutting fluid and preparing method thereof

Abstract

The invention discloses an antioxidant lubricating cutting fluid. The fluid comprises the ingredients of, by weight: 1-2 parts of 2-bromine-4-methyl phenol, 2-3 parts of lauryl dimethyl amine oxide, 0.7-1 parts of 8-hydroxyl group oxyquinoline, 0.2-0.3 parts of copper sulphate, 10-17 parts of styrene, 3-4 parts of maleic anhydride, 0.1-0.2 parts of benzoyl peroxide, 5-7 parts of silicon dioxide, 1-2 parts of propargyl alcohol, 0.4-1 parts of sodium nitride, 0.6-1 parts of aluminium chloride, kh5600-1 parts of silane coupling agent, 0.1-0.2 parts of sodium ascorbate, 3-4 parts of tributyl borate, 0.6-1 parts of diisopropyl ethanolamine, 0.6-1 parts of triallyl isocyanurate, 2-3 parts of ammonium molybdate, 1-2 parts of allyl thiourea, 1-2 parts of magnesium fluoride. Hydroxyl group with unsaturation residual bonds and hydroxyl groups in different bonding states on the surface of nano silica enables the surface activity greatly which can be easily deposited on the metal friction surface to improve the lubricating property of the cutting fluid.

Description

technical field [0001] The invention relates to the technical field of cutting fluids, in particular to an anti-oxidation lubricating cutting fluid and a preparation method thereof. Background technique [0002] Due to its three-dimensional network structure, excellent stability, reinforcement and thickening properties, low price, and easy preparation, nano-silica is widely used in cutting fluids to improve the load-bearing and anti-corrosion capabilities of cutting fluids. Nano-silica has a large specific surface area and high specific surface energy. It is easy to agglomerate in the cutting fluid to form secondary particles, resulting in a decrease in the performance of strengthening and toughening. At the same time, the hydroxyl group on the surface also strengthens this phenomenon. Therefore, improving the dispersibility of nano-silica in cutting fluid is an urgent problem to be solved; [0003] Physical blending, chemical grafting and other methods can be used to enhan...

Problems solved by technology

Some grafted PS and PSMA on the surface of nano-silica by in-situ free radical polymerization to prepare amphiphilic nano-silica, and some used dimethyldichlorosilane dry process to prepare nano-silica with better dispersion Silicon oxide, some polycondensation reactions on the surface of nano-silica through polyethylene glycol and sebacic acid, improve the dispersion of nano-silica, and some use "click" chemistry combined with RAFT and ATRP polymerization in Grafting polyacrylamide and polystyrene on the surface of the particles improves the dispersion of the particles. The current study found that surface grafting of polymers is the most effective way to improve the dispersion of nano-silica, but grafting often occurs in the research The functional group of the reaction is only located at one end of the molecular chain, and there are few reports on the molecular chain containing multiple functional groups;
