Problems solved by technology

[0004] Chinese patent CN1667101A adopts polyethylene glycol and fatty alcohol polyoxyethylene ether as dispersant, and its shortcoming is: the dispersibility of polyethylene glycol is relatively poor, and the amount of adding is more, must add fatty alcohol polyoxyethylene ether in addition As a dispersant, the addition of fatty alcohol polyoxyethylene ether will cause more foam troubles, and it is necessary to add an additional silicone defoamer, resulting in a relatively high solid content of the entire cutting liquid, so that the chemical oxygen demand of the wastewater is relatively high. high, difficult to handle
[0005] Chinese patent CN 106398849 A uses polyether and phosphoric acid ester as the main raw materials. Although the cutting performance is excellent, the foam is too high, and a defoamer needs to be added.
Also, because of the addition of phosphorus-containing raw materials, wastewater treatment is very troublesome
[0006] To sum up, although researchers have developed a variety of cutting fluids, so far, none of the cutting fluids is perfect, and it is difficult to meet the requirements of users and environmental protection.

Abstract

The invention belongs to the technical field of cutting fluids and particularly relates to a diamond wire cutting fluid for environment-friendly magnetic materials, comprising 3.0-5.0% of alcohol amines, 3.0-5.0% of alkynol, 0.5-1.0% of a precipitating agent, and the balance of deionized water. The diamond cure cutting fluid with a deionized water as a solvent has good dispersibility and low foam,zero need for defoaming agents, and low wastewater COD.

Description

technical field [0001] The technical field of the cutting fluid of the present invention, in particular relates to an environment-friendly diamond wire cutting fluid for magnetic materials. Background technique [0002] At present, diesel oil (kerosene) is used for cutting NdFeB magnetic materials in China. Due to the strong smell of diesel oil, it is extremely harmful to the health of operators, and diesel oil is harmful to human skin. [0003] Secondly, during the processing of diesel oil, a large amount of steam will be generated. On the one hand, it will pollute the environment, and at the same time, it will easily cause fire, which is not conducive to safe production. In the context of increasingly stringent environmental protection requirements, looking for a water-based cutting fluid is a research hotspot. [0004] Chinese patent CN1667101A adopts polyethylene glycol and fatty alcohol polyoxyethylene ether as dispersant, and its shortcoming is: the dispersibility of ...
