Cutting lubricant containing rosin and preparing method thereof

Abstract

The invention discloses a cutting lubricant containing rosin. The cutting lubricant is prepared from the following raw materials, by weight, 1-2 parts of sodium hexametaphosphate, 0.2-0.3 parts of copper sulfate, 10-17 parts of phenylethylene, 3-4 parts of maleic anhydride, 0.1-0.2 parts of benzoyl peroxide, 5-7 parts of nanometer silica, 1-2 parts of propargyl alcohol, 0.4-1 part of sodium nitride, 0.6-1 part of aluminium chloride, span 802-3, a silane coupling agent kh5600.7-1, 0.1-0.2 parts of sodium ascorbate, 0.7-1 part of alpha-bromocinnamaldehyde, 2-3 parts of dimethyl succinate, 4-5 parts of petroleum calcium sulfonate, 1-2 parts of ethelene glycol monophenyl ether, 2-3 parts of polyoxyethylene stearate, 1-2 parts of polyaspartic acid, 0.8-1 parts of monoethanolamine, 2-3 parts of sodium dodecyl benzene sulfonate and 1-2 parts of potassium oleate. In the cutting lubricant, unsaturated residual bonds and hydroxyl groups with different bonding states are present on the surface of nanometer silica so that the surface has the relatively high surface activity; the cutting lubricant is easy to deposit on the metal friction surface and is increased in lubricity.

Description

technical field [0001] The invention relates to the technical field of cutting fluids, in particular to a lubricating cutting fluid containing rosin 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;
