Problems solved by technology

[0002] Nowadays, in machinery factories, when using CNC machine tools to cut workpieces, coolant must be used to cool the tool to reduce the heat generated during the process and ensure the smooth progress of the cutting process. The coolant currently used is generally ethylene glycol-type coolant , Ethylene glycol type coolant has certain toxicity, and some inorganic additives in the coolant have carcinogenic effect. Some coolants cannot meet the needs of different temperatures at the same time. They are easy to smell in summer, difficult to dilute in winter, and have poor anti-rust effect. It is difficult to meet the four purposes of cooling, lubrication, cleaning, and anti-rust at the same time. The body of the victim is not harmed, and the emission is qualified

Abstract

The invention discloses numerical-control machine tool cooling liquid. The numerical-control machine tool cooling liquid comprises, by weight, 20-55 parts of rapeseed oil, 5-10 parts of sodium hydroxide, 4-10 parts of tetramethyl orthosilicate, 30-50 parts of rice milk, 2-5 parts of organic silicon defoamer and 3-8 parts of octanoic dicyclohexylamine. The rice milk is environment friendly, weakly alkaline and high in dirt removing ability, has better lipophilicity and hydrophilcity as starch denaturizes after heated and pressured and thereby is higher in cleaning ability and can easily adsorb oil; sodium hydroxide, tetramethyl orthosilicate and rice milk are reasonably prepared and can play a role in cooling and cleaning, so that the rapeseed oil is better in lubricating effect; the added organic silicon defoamer and octanoic dicyclohexylamine play a role in defoaming and derusting. The preparation method of the cooling liquid adopts high-temperature pressuring reaction to make various components mixed together, so that the cooling liquid is moderate in lubricating effect, soft, free of side effect, quick in cooling and good in derusting effect, and quality stability of workpieces is guaranteed.
