Organic amine corrosion inhibition lubricating cutting fluid and preparation method thereof

Abstract

The invention discloses an organic amine corrosion inhibition lubricating cutting fluid. The cutting fluid is prepared from, by weight, 2-3 parts of coco fatty acid diethanol amide, 1-2 parts of potassium perfluorobutane sulfonate, 1-2 parts of dodecafluoroheptyl-propyl-trimethoxysilane, 0.7-1 part of sodium thiosulfate, 0.2-0.3 part of copper sulfate, 10-17 parts of styrene, 3-4 parts of maleic anhydride, 0.1-0.2 part of benzoyl peroxide, 5-7 parts of nano silicon dioxide, 1-2 parts of propargyl alcohol, 0.4-1 part of sodium nitride, 0.6-1 part of aluminum chloride, 2-3 parts of Span 80, 0.7-1 part of silane coupling agent kh5600, 0.1-0.2 part of sodium ascorbate, 1-2 parts of alkylated diphenylamine, 1-2 parts of diacetone acrylamide, 2-3 parts of salatrim, 3-4 parts of polyethylene glycol and 1-2 parts of calcium silicate. Due to unsaturated residual bonds existing on the surface of nano silicon dioxide and hydroxyl groups in different bonding states, the surface of the nano silicon dioxide has very high surface activity, the nano silicon dioxide can easily deposit on a metal friction surface, and the lubricating performance of the cutting fluid is improved.

Description

technical field [0001] The invention relates to the technical field of cutting fluids, in particular to an organic amine corrosion-inhibiting 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 ...

AI Technical Summary

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;
