Embodiment 1

[0049] A kind of cutting fluid, by mass percentage, its raw material composition is shown in table 1.

[0050] Among them, urotropine is used as corrosion inhibitor; emulsifier OP-10 is used as emulsifier; DOWFAX2A1 is used as surfactant; ethylene glycol phenyl ether is used as cooling agent (and organic solvent); citric acid is used as acidity regulator.

[0051] The preparation method of this cutting fluid comprises the following steps:

[0052] Step 1, adding corrosion inhibitor, emulsifier, surfactant and benzyl chloride into the cooling agent, stirring evenly;

[0053] Step 2, adding an acidity regulator during stirring to adjust the pH to 4.5-5.3;

[0054] Step 3, dilute by adding deionized water during slow stirring.

Embodiment 2

[0056] The difference from Example 1 is that, in terms of mass percentage, the cutting fluid raw material components are shown in Table 1.

Embodiment 3

[0058] The difference from Example 1 is that, in terms of mass percentage, the cutting fluid raw material components are shown in Table 1, and DOWFAX 2A1 is used to completely replace the emulsifier OP-10.

Abstract

The invention discloses a cutting fluid, which comprises the following components in terms of mass percentage: 15-25% of an emulsifier; 5-15% of a surfactant; 5-15% of a cooling agent; 1-5% of a corrosion inhibitor; acidity Regulator 1-3%; the rest is water; the corrosion inhibitor uses urotropine. The invention has the following advantages: urotropine, also known as hexamethylenetetramine, is an anodic corrosion inhibitor mainly for inhibiting metal anode dissolution, thereby improving the corrosion resistance of metal workpieces. At the same time, part of urotropine is decomposed into ammonia gas and formaldehyde under the acidic action of the acidity regulator and dissolved in water, and ammonia gas and formaldehyde have a strong reducing effect, so as to prevent the workpiece from being rapidly damaged due to high temperature during the cutting process. Oxidation and rusting occur. Furthermore, under the reducing action of ammonia and formaldehyde, it is difficult to breed bacteria in the cutting fluid, and has good bactericidal performance, so it will not stink.

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...
