Embodiment 1

[0046] Accurately weigh 20g of triethanolamine, dissolve it in 50ml of deionized water and stir evenly to make an alkaline solution with a pH value of 10.5, then weigh 3.0g of glycerin with a pipette gun and add it to the triethanolamine solution, and record it as A; Dissolve 0.5g of triethanolamine borate and 1.0g of sodium dodecylbenzenesulfonate in 10ml of deionized water, stir well for later use, record as B and C; add solution A and solution B to solution C successively , mixed and stirred evenly to make solution D; then 0.5g of antifoaming agent simethicone was added to solution D, and stirred evenly to make light yellow transparent clear liquid E, that is, fully synthetic crystal cutting fluid.

[0047] The cutting fluid is light yellow transparent solution, non-toxic, odorless, non-foaming, excellent lubricity, good cutting quality, high cutting efficiency, less dosage, long service life, and can achieve excellent surface finish.

Embodiment 2

[0049] Accurately weigh 10 g of triethanolamine, dissolve it in 50 ml of deionized water and stir evenly to make an alkaline solution with a pH value of 10.0, then weigh 5.0 g of glycerin with a pipette gun and add it to the triethanolamine solution, denoted as A; Dissolve 0.5g of triethanolamine borate and 1.0g of sodium dodecylbenzenesulfonate in 10ml of deionized water, stir well for later use, record as B and C; add solution A and solution B to solution C successively , mixed and stirred evenly to make solution D; then 0.3g of antifoaming agent simethicone was added to solution D, and stirred evenly to make colorless transparent clear liquid E, that is, fully synthetic crystal cutting fluid.

[0050] The cutting fluid is a colorless and transparent solution, non-toxic, odorless, with a small amount of fine foam, excellent lubricity, good cutting quality, high cutting efficiency, less dosage, long life, and excellent surface finish.

Embodiment 3

[0052] Accurately weigh 15g of triethanolamine, dissolve it in 50ml of deionized water and stir evenly to make an alkaline solution with a pH value of 10.5, then weigh 3.5g of glycerin with a pipette gun and add it to the triethanolamine solution, and record it as A; Dissolve 0.8g of triethanolamine borate and 1.8g of sodium dodecylbenzenesulfonate in 10ml of deionized water, stir well for later use, record as B and C; add solution A and solution B to solution C successively , mixed and stirred evenly to make solution D; then 0.2 g of antifoaming agent simethicone was added to solution D, and stirred evenly to make colorless transparent clear liquid E, that is, fully synthetic crystal cutting fluid.

[0053] The cutting fluid is a colorless and transparent solution, non-toxic, odorless, with a little foam, excellent lubricity, good cutting quality, high cutting efficiency, less dosage, long life, and can achieve excellent surface finish.

Abstract

The invention relates to a total-synthesis crystal cutting fluid and belongs to the industry of cutting fluid, particularly the technical field of production of artificial crystal cutting fluid. The cutting fluid provided by the invention is mainly prepared from a cleaning agent (sodium dodecylbenzene sulfonate), a preservative (triethanolamine borate), a lubricant (glycerin), an antirust agent (triethanolamine), a defoaming agent (dimethicone) and deionized water. The cutting fluid disclosed by the invention is alkaline, is mainly prepared by scientific compounding and matching of a great quantity of pure water and multiple superstrong functional agents, does not contain sodium nitrite having a carcinogenic effect to a human body, has an efficacy of keeping the pH value unchanged in the cutting process, realizes direct application of single components, is free from toxicity and pollution, is applicable to a semi-automatic and automatic cutting production line of various processes, issimple in process, convenient to operate, excellent in lubricating property, good in cutting quality, high in cutting efficiency, and less in foam generation, and can achieve an excellent surface smoothness. Compared with like products at home and abroad, the cutting fluid is less in use amount and long in life, and the cost can be saved by 1 / 6-1 / 8.

Description

technical field [0001] The invention relates to the cutting fluid industry, in particular to the technical field of production of artificial crystal cutting fluid. Background technique [0002] Cutting fluid is an industrial liquid used in industrial production to cool and lubricate cutting tools and workpieces. It can be divided into water-based cutting fluid and oil-based cutting fluid. Water-based cutting fluid has good cooling effect and poor lubricating performance; compared with oil-based cutting fluid, it has good lubricating performance and poor cooling effect. However, due to the large amount of heat generated during high-speed cutting and the poor heat transfer effect of oil-based cutting fluid, the temperature in the cutting area will be too high, resulting in smoke and fire in the cutting oil, and there are many potential safety hazards and environmental pollution; and because the workpiece If the temperature is too high, thermal deformation will affect the mach...
