Environment-friendly wire cutting liquid and preparation method thereof

Abstract

The invention discloses environment-friendly wire cutting liquid. The environment-friendly wire cutting liquid is prepared from the following substances in parts by weight: 5.8 to 6.2 parts of sorbitan monooleate, 5.2 to 6.5 parts of oleic acid, 3.8 to 4.3 parts of antirust agent, 3.5 to 4.2 parts of Turkey red oil, 0.8 to 1.1 parts of potassium hydroxide, 0.6 to 1.1 parts of deionized water, 1.0to 1.4 parts of methyl alcohol, 0.01 to 0.05 part of 1H- benzotriazole, 1 to 1.2 parts of anticorrosive inhibitor, 70 to 80 parts of low-viscosity naphthenic base oil and the balance of a less amountof defoaming agent. A preparation method of the environment-friendly wire cutting liquid comprises the following steps: (1) successively adding the low-viscosity naphthenic base oil, the sorbitan monooleate, the oleic acid and the Turkey red oil into a mixing kettle according to a ratio, and then heating and stirring; and (2) then successively adding potassium hydroxide, the deionized water, the antirust agent, methyl alcohol, benzotriazole, the anticorrosion inhibitor and the defoaming agent according to a ratio, and stirring. By adopting the environment-friendly wire cutting liquid and the preparation method thereof, the safety and environment-friendly performance of the cutting liquid can be greatly improved, the overhigh temperature in a cutting region is avoided, a cut workpiece is good in heat conductivity, free from smoke and deterioration, safe, environmentally friendly, and free from peculiar smell.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a green and environment-friendly wire cutting fluid and a preparation method thereof. Background technique [0002] The wire cutting fluid used for CNC wire cutting machine tools and machining machine tools is currently formulated with general mineral base oil oil-soluble additives and sodium nitrite. In this case, the wire cutting fluid prepared according to the current technology has poor heat transfer effect , the temperature in the cutting area will be too high, causing the cutting fluid to produce smoke, fire and other phenomena, and it is easy to be infected by bacteria, smelly, which is not conducive to personal health, and has low safety and environmental protection performance. The present invention is aimed at such key technical problems at present. The overall optimization is carried out to prolong the service life of the wire cutting fluid and improve the safe...
