A kind of environment-friendly wire cutting fluid and preparation method thereof

Abstract

The invention belongs to the fields of metal machining and fine chemical product preparation, and relates to a wire cutting fluid which does not require coupling reaction, and in particular to an environment-friendly wire cutting fluid and a preparation method thereof. The environment-friendly wire cutting fluid consists of the following substances in parts by weight: 1 to 14 parts of rosin, 1 to14 parts of vegetable oleic acid, 10 to 30 parts of alkaline liquor, 20 to 50 parts of tap water, 1 to 5 parts of antirust, 5 to 10 parts of petroleum sodium sulfonate, 2 to 5 parts of synthetic oil, 1 to 15 parts of polyethylene glycol, 3 to 8 parts of alcohol and 0.1 parts of anti-foaming agent, wherein the mass concentration of the alkaline liquor is 50 percent. The environment-friendly wire cutting fluid has good heat resistance and light resistance, and is suitable for use in cold regions; and the environment-friendly wire cutting fluid can also meet high wire cutting speed.

Description

technical field [0001] The invention belongs to the field of metal processing and preparation of fine chemical products, relates to a wire cutting fluid without coupling reaction, in particular to an environment-friendly wire cutting fluid and a preparation method thereof. Background technique [0002] Wire cutting fluid is mainly used in CNC wire cutting machine tools, generally has good cooling, lubrication, cleaning and antirust functions, and also has other special properties: a certain dielectric strength, deionization, arc extinguishing, prevention of broken wires and Long service life, safe and non-toxic, etc. The ideal processing smoothness and processing efficiency can be obtained by using a suitable wire cutting fluid, and the service life of the machine tool can be extended. [0003] In the past, wire cutting fluid was mainly used in precision machining of hard materials such as metals; now with the rapid development of the global solar energy and microelectronic...

AI Technical Summary

Problems solved by technology

[0005] But the wire cutting fluid that mainly sells on the existing market mainly comprises potassium hydroxide, mineral oil, oleic acid, lye, ethanol, diethylene glycol butyl ether etc., and the defective of its existence has: one, existing wire cutting emulsified oil Base oil (mineral oil) must be used as an essential raw material for production, and the waste oil of base oil (mineral oil) is quite serious for environmental pollution

However, many private small, medium and micro enterprises or small metal processing workshops will not dispose of them in accordance with national regulations, and what is more, they will directly discharge the waste emulsion directly into the natural environment or urban sewage pipes

Very serious damage to the environment

Second, the production of the existing wire-cut emulsified oil consumes a lot of energy, and the production needs to raise the temperature of the raw materials to 130-140°C

Since the burning of heavy oil, coal, and biomass fuels has been banned due to environmental protection requirements, continuing to produce with the old process is not conducive to production cost control

The third is that the working fluid of the existing product is a milky white turbid liquid after being mixed with water, which is not friendly to the environment, and it is not heat-resistant and light-resistant

Fourth, the existing products have been tested on-site by the intermediate wire cutting machine, and the wire cutting fluid can meet the actual cutting efficiency up to 100mm 2 / min, the cutting speed needs to be improved to adapt to the market trend

Fifth, the cloud point of the existing product concentrate is ≤ -10°C, and its use in cold regions is limited
