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.
