Problems solved by technology
[0005] However, the existing microemulsion water-soluble cutting fluid usually contains a relatively high proportion of base oil in the formula, and the oxidation and corruption of the oil will easily affect the service life of the entire product. For this reason, it is usually necessary to add a bactericide to prolong the service life. Most fungicides are irritating to the skin and harmful to the human body, and most of the fungicides are sold at a high price, resulting in high manufacturing costs for water-soluble cutting fluids

Embodiment Construction
[0014] The water-soluble machining cutting fluid prepared by the water-soluble machining cutting fluid preparation method comprises the following components by mass percentage:
[0015]
[0016] It is characterized in that the preparation method comprises the following steps:
[0017] (1) Add proportioned amounts of phosphoric acid, diethanolamine, tolyltriazole and its derivatives, hexamethylenetetramine and its derivatives, and water softener into water in sequence, heat to 40-50°C, and Stir to dissolve completely;
[0018] (2) In the mineral oil of proportioning quantity, add the polyacrylamide of proportioning quantity, sulfate ester salt successively, stir at normal temperature until uniform and transparent;
[0019] (3) Pour the liquid in step (2) into the liquid in step (1), stir at room temperature until the solution becomes transparent, add the high-carbon alcohol fatty acid ester complex, continue stirring for 25-35 minutes, and make the finished product.

The invention discloses a preparing method of water-soluble machining cutting fluid. The method includes the following steps that 1, a blending quantity of phosphoric acid, diethanol amine, methyl-1H-benzotriazole and derivatives thereof, hexamethylenetetramine and derivatives thereof, and water softener are sequentially added into water, heated to 40-50 DEG C and stirred at the normal temperature to be fully dissolved; 2, a blending quantity of polyacrylamide and sulphate are sequentially added into a blending quantity of mineral oil, and stirring is carried out at the normal temperature till the liquid is uniform and transparent; 3, the liquid in the step 2 is poured into the liquid in the step 1, stirring is carried out at the normal temperature till the solution is transparent, a high-alcohol fatty acid ester compound is added, stirring continues for 25-35 min, and the finished product is obtained. The water-soluble machining cutting fluid prepared with the preparing method of the water-soluble machining cutting fluid avoids the irritating harm of bactericide to skin on the premise of a long service life, and meanwhile the manufacturing cost is reduced.
Description
technical field [0001] The invention relates to a method for preparing a cutting fluid for machining, in particular to a method for preparing a water-soluble cutting fluid for machining, and belongs to the technical field of cutting fluid for machining. Background technique [0002] Cutting fluid is an industrial liquid used in metal cutting and grinding to cool and lubricate cutting tools and workpieces. Cutting fluid is made of various functional additives through scientific compounding and has good cooling performance. , Lubrication performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function. [0003] Traditional cutting fluids are mostly soap-based emulsions, which have the disadvantages of being easy to stink in summer and difficult to dilute in winter. Soap-based emulsions in the prior art are gradually replaced by water-soluble cutting fluids. [0004] Water-soluble cutting fluid is a new generation of semi-synthetic microemulsion wa...
