Embodiment 1

[0045] Take an ordinary water-based cutting fluid A, sample 1: add 0.5% EmulsogenCOL 100 to water-based cutting fluid A; sample 2: add 0.5% ether carboxylic acid compound package 1 to water-based cutting fluid A. Two samples were obtained for product processing. Die-casting aluminum alloy was processed on two identical CNC machines. The liquid tank was 200L. The experimental data are as follows:

[0046]

[0047]

[0048]

[0049]Comparison results: 15-30L of 4% new liquid is added to the CNC processing tanks of sample 1 and sample 2 every shift (12h) to ensure that the tank is about 180L. After sample 1 was 2016.01.10, the concentration could not be increased, and the liquid used was separated and could not be used. Sample 2 is used normally. The results show that the effect of adding a single ether carboxylic acid to cutting fluid A is not as good as that of ether carboxylic acid compound package 1.

Embodiment 2

[0051] Take the same ordinary water-based cutting fluid A, sample 3: add 1% AkypoLF4 to water-based cutting fluid A; sample 4: add 1% ether carboxylic acid compound package 1 to water-based cutting fluid A. Two samples were obtained for product processing. Die-casting aluminum alloy was processed on two identical CNC machines. The liquid tank was 200L. The experimental data are as follows:

[0052]

[0053]

[0054]

[0055] Comparison results: 15-30L of 4% new liquid is added to the CNC processing tanks of sample 3 and sample 4 every shift (12h) to ensure that the tank is about 180L. The concentration of sample three cannot be increased after January 1, 2016, and the liquid used is separated and cannot be used. Sample four is used normally. The results show that the addition of a single ether carboxylic acid to cutting fluid A is not as effective as the ether carboxylic acid compound package 1.

Embodiment 3

[0057] Take the same common water-based cutting fluid A, sample five: add 0.5% Akypo LF4 and 0.5% Akypo RO 90 VG to water-based cutting fluid A; sample four: add 1% ether carboxylic acid to water-based cutting fluid A Compound package one. Two samples were obtained for product processing. The die-casting aluminum alloy was processed on two identical CNC machines. The liquid tank was 200L. The experimental data are as follows:

[0058]

[0059]

[0060]

[0061] Comparison results: 15-30L of 4% new liquid is added to the CNC processing tanks of sample 5 and sample 4 every shift (12h) to ensure that the tank is about 180L. The concentration of sample 5 cannot be increased after 2016.01.1, and the liquid used is separated and cannot be used. Sample four is used normally. The results show that the effect of adding the two ether carboxylic acids to the cutting fluid is not as good as that of the ether carboxylic acid compound package one.

Abstract

The invention provides an ether carboxylic acid compound ofa water-based cutting solution. The ether carboxylic acid compound is prepared from, by weight, 32.14-39.28% of ether carboxylic acid,19.29%-23.57%short-chain ether carboxylate and 38.57-47.15% of long-chain ether carboxylat, wherein the brand of ether carboxylic acid is Emulsogen COL100, the brand of the short-chain ether carboxylic acid is AkypoLF4, and the brand of the long-chain ether carboxylic acid is Akypo RO 90 VG. The invention further provides a preparation method of the ether carboxylic acid compound ofthe water-based cutting solution and the water-based cutting solution. Compared with the prior art, the ether carboxylic acid compound has the following advantages that the cost is low, the anti-hard water performance is excellent, the compound is chelated with Ca<2+> and Mg<2+>in water, a generated chelate has a good dispersion effect and low bubble performance, the used solution does not produce a large amount of foam, and the ether carboxylic acid compound is environmentally friendly and low in toxicity and has good biodegradability.

Description

technical field [0001] The invention relates to the field of water-based cutting fluid, in particular to an ether carboxylic acid compound of water-based cutting fluid, a preparation method and the water-based cutting fluid. Background technique [0002] Water-based cutting fluids include synthetic cutting fluids, semi-synthetic cutting fluids and emulsions. During use, the stock solution of cutting fluid is diluted with water for use. Water generally contains certain minerals, these minerals are non-hardness salts (such as potassium, sodium) and hardness salts (such as calcium, magnesium). The hardness of water is calculated according to the amount of hardness minerals contained in the water. The hardness of water can be divided into three levels, namely soft water (<150ppm), medium hard water (150-300ppm) and hard water (>300ppm). If the hardness of water is low, the liquid used will easily foam; if the hardness of water is high, the liquid used will be prone to s...
