Extreme-pressure lubricating and cutting liquid and preparation method thereof

Abstract

The invention discloses extreme-pressure lubricating and cutting liquid which consists of the following raw materials in parts by weight: 1 to 2 parts of N-hydroxymethyl acrylamide, 3 to 4 parts of isopropyl palmitate, 1 to 2 parts of para toluene sulfonamide, 4 to 6 parts of T405 sulfurized olefin cottonseed oil, 0.2 to 0.3 part of copper sulfate, 10 to 17 parts of styrene, 3 to 4 parts of maleic anhydride, 0.1 to 0.2 part of benzoyl peroxide, 5 to 7 parts of nano-silicon dioxide, 1 to 2 parts of propargyl alcohol, 0.4 to 1 part of sodium nitride, 0.6 to 1 part of aluminum chloride, 0.7 to 1 part of a silane coupling agent kh560, 0.1 to 0.2 part of sodium ascorbate, 2 to 3 parts of polyoxypropylene glycerol ether, 2 to 3 parts of polyglycerol fatty acid ester, 0.1 to 0.2 part of molybdenum oxide and 2 to 3 parts of calcium phosphate. Unsaturated residual bond and hydroxyl with different bonding states which exist on the surface of the nano-silicon dioxide enable the surface of the nano-silicon dioxide to achieve high surface activity, and the nano-silicon dioxide is easily deposited on the friction surface of metal, so that the lubricating property of the cutting liquid is improved.

Description

technical field [0001] The invention relates to the technical field of cutting fluid, in particular to an extreme pressure 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 enha...

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;
