Cutting fluid

Abstract

The invention discloses cutting fluid, which is prepared from the following ingredients in percentage by mass: 15 to 25 percent of emulsifiers, 5 to 15 percent of surfactants and 5 to 15 percent of heat radiation agents, 1 to 5 percent of a corrosion inhibitor, 1 to 3 percent of an acidity regulator and the balance of water, wherein the corrosion inhibitor uses methenamine. The cutting fluid has the following advantages that the methenamine is also called as hexamine, and is an anode corrosion inhibitor mainly inhibiting the metal anode dissolution, thus improving the anti-corrosion performance of metal workpieces. Meanwhile, the methenamine is partially decomposed into ammonia gas and formaldehyde to be dissolved into water under the acidic effects of the acidity regulator; the ammonia gas and formaldehyde have a strong reduction effect, so that the fast oxidization and rusting of workpieces due to high temperature in the cutting fluid is avoided. Under the reduction effects of ammonia gas and formaldehyde, bacteria are difficult to grow in the cutting fluid; good sterilization performance is realized, so that smelliness cannot occur.

Description

technical field [0001] The invention relates to the technical field of metal processing, more specifically, it relates to a cutting fluid for capillary. Background technique [0002] Cutting fluid is an industrial liquid used in metal cutting and grinding to cool and lubricate cutting tools and machined parts. It is used in various machine tools such as turning, milling, planing, grinding, and gear and thread processing. Has a very large amount. [0003] The Chinese patent with the notification number CN102433207B discloses a cutting fluid. The formula components of the cutting fluid are as follows by weight: antirust agent: triethanolamine 5-10%, diethanolamine 5-10%, monoethanolamine 2-5%, 2-amino-2-methyl-1-propanol 2-5%, boric acid 2-7%, undecane dibasic acid 0.5-4%, dodecane dibasic acid 0.5-4%, polycarboxylic acid 2-7%; lubricant: vegetable oleic acid 2-6%, pentaerythritol oleate 3-7%, EO / PO copolymer 3-10%, tall oil 2-5%, vegetable oleic acid polyester 3-7% , chlor...

AI Technical Summary

Problems solved by technology

[0004] The formula components of this kind of cutting fluid are relatively complicated, which will inevitably lead to its relatively cumbersome preparation process, which needs to be improved.
