Aluminium alloy cutting liquid with long service life and preparation method thereof

Abstract

The invention relates to the field of metal cutting liquids, in particular to an aluminium alloy cutting liquid with a long service life and a preparation method thereof. The semi-synthetic cutting liquid provided by the invention is prepared from 10 to 30 percent of mineral oil, 5 to 15 percent of alcohol amine, 5 to 12 percent of an emulsifying agent, 3 to 8 percent of an anti-rusting agent, 3 to 10 percent of a lubricating agent, 1 to 4 percent of a corrosion inhibitor, 1 to 4 percent of an extreme pressure agent, 0.5 to 1 percent of a defoaming agent, and 1 to 3 percent of a sterilizing agent. According to the formula of the aluminium alloy cutting liquid, conventional monoethanolamine, diethanol amine and triethanolamine serving as pH regulating agents are abandoned, and through a special compounding mode, the aluminium alloy cutting liquid has higher stability, and the cost is reduced. Secondly, the using amount of the extreme pressure agent is reduced by regulating the using amounts of various raw materials; moreover, excellent corrosion preventing and lubricating effects of the cutting liquid are maintained; the cutting liquid can be used for a long time; the replacement period of the cutting liquid provided by the invention is about one year; the cutting liquid is environment-friendly and has extremely low damage to a human body.

Description

technical field [0001] The invention relates to the field of metal cutting fluids, in particular to an aluminum alloy cutting fluid with long service life and a preparation method thereof. Background technique [0002] In the prior art, the aluminum alloy has low density, but relatively high strength and good plasticity. It can be processed into various profiles, has excellent thermal conductivity and good corrosion resistance, and is widely used in industry. It is inferior to steel, but the chemical activity of aluminum alloy is strong, the texture is very soft, and the viscosity is strong. Problems such as sticking to the knife and discoloration are prone to occur during processing. Therefore, the demand for special cutting fluids for aluminum alloy processing is also increasing. [0003] The service life of metal cutting fluids has always been the focus of people's attention. Traditional metal cutting fluids need to add alcohol amines such as monoethanolamine and triethan...
