Anti-rust micro-emulsified cutting fluid and preparation method thereof

Abstract

The invention discloses anti-rust micro-emulsified cutting fluid which is prepared from the following raw materials in parts by weight: 1 to 2 parts of calcium fluoride, 2 to 3 parts of aluminum isopropoxide, 2 to 4 parts of nitritotriacetic acid phosphate, 0.4 to 1 part of bromohexadecane, 0.3 to 1 part of tetrabutylammonium bromide, 6 to 7 parts of copper hydroxide, 20 to 30 parts of a formic acid aqueous solution with the concentration of 10 to 15 percent, 4 to 5 parts of a carbon nano tube, 50 to 60 parts of methyl silicone oil, 3 to 4 parts of sodium dodecyl sulfate, a proper amount of water, 0.4 to 1 part of pyromellitic dianhydride, 3 to 4 parts of polyvinyl alcohol, 0.4 to 1 part of benzyltriphenylphospho, 1 to 2 parts of zinc ricinate, 0.3 to 1 part of sucrose fatty acid ester, 0.6 to 1 part of N-sodium lauroyl sarcosine, and 0.3 to 1 part of 2-mercapto benzimidazole. According to the anti-rust micro-emulsified cutting fluid, after the esterized carbon nano tube and copper formate are subjected to hybrid ball grinding, Cu<2+> can be adhered to the surface of the carbon nano tube through pyrolysis, so that nano copper particles are generated on the surface of the carbon nano tube.

Description

technical field [0001] The invention relates to the technical field of cutting fluids, in particular to an antirust microemulsion cutting fluid and a preparation method thereof. Background technique [0002] Because nanoparticles have many properties that conventional solids do not have, such as low melting point, high ductility, easy diffusion, etc., their hardness, toughness, shear resistance, etc. may also change, which means that they cannot be used as Solid particles of lubricating materials may have lubricating properties when they are at the nanometer level, and are likely to have some boundary lubrication mechanisms different from traditional additives; secondly, nano-lubricating oil additives replace traditional organic compounds such as S, P, and Cl. Grinding additives are expected to solve the corrosion and environmental problems caused by S, P, and Cl to the base metal; however, some problems need to be solved when applying nanoparticles to cutting fluids to redu...

[0002] Because nanoparticles have many properties that conventional solids do not have, such as low melting point, high ductility, easy diffusion, etc., their hardness, toughness, shear resistance, etc. may also change, which means that they cannot be used as Solid particles of lubricating materials may have lubricating properties when they are at the nanometer level, and are likely to have some boundary lubrication mechanisms different from traditional additives; secondly, nano-lubricating oil additives replace traditional organic compounds such as S, P, and Cl. Grinding additives are expected to solve the corrosion and environmental problems caused by S, P, and Cl to the base metal; however, some problems need to be solved when applying nanoparticles to cutting fluids to reduce friction and wear;

[0003] Due to the large specific surface area and high surface energy of nanoparticles, they are easy to agglomerate in solvents, especially in non-aqueous media such as lubricating oil. If nanoparticles agglomerate into large particles in lubricating oil, it is like oil The same as impurities, it will reduce the performance of lubricating oil." At the same time, the dispersion and stability of nanoparticles are two closely related but independent factors. Good dispersion is not necessarily good stability. In addition, cutting fluids are generally used at high temperatures. 1. Under the high-pressure working environment, the colloidal nanoparticles in the suspension state in the cutting fluid can easily destroy its stability in such a working environment, resulting in agglomeration and coagulation, and finally the nanoparticles lose their anti-wear properties;
