preparation example Construction

[0037] refer to figure 1As shown in the work flow chart, the application provides a method for preparing aluminum and water-based metalworking cutting fluid, comprising the following steps:

[0038] Step 101, mixing organic base, protonic acid, antirust agent and water to obtain a first mixed solution;

[0039] Step 102, mixing the first mixed solution with mineral oil, aluminum corrosion inhibitor and emulsifier in sequence to obtain a second mixed solution;

[0040] Step 103, mixing the second mixed liquid with the bactericide and defoamer, and stirring evenly to obtain a clear and transparent water-based cutting fluid for steel and aluminum combined.

[0041] In the above-mentioned cutting fluid preparation process, the mixing in the step is preferably carried out under stirring conditions, and the mixing temperature is only at room temperature, and the operation of step 102 can only be performed after the solid raw materials are completely dissolved in step 101, and the s...

Abstract

The invention provides water-based metal processing cutting fluid for steel and aluminum and a preparation method of the water-based metal processing cutting fluid. The cutting fluid comprises the following components in percentage by weight: mineral oil, an emulsifier, an organic base, protonic acid, an antirust agent, an aluminum corrosion inhibitor, a bactericide, a defoaming agent and water. The protonic acid and the antirust agent are compounded on the surface of a metal workpiece to form a protective film to inhibit corrosion of the metal workpiece, so that when the cutting fluid is applied to a cutting process ofa steel workpiece, the steel workpiece is prevented from being corroded; and the aluminum corrosion inhibitor can inhibit corrosion of an aluminum workpiece during machining, so that the aluminum workpiece is prevented from being corroded when the cutting fluid is applied to the cutting process of the aluminum workpiece. Therefore, the cutting fluid provided by the invention can meet the machining requirements of steel parts and / or aluminum workpieces. In addition, when the cutting fluid provided by the invention is used for simultaneously cutting a steel part and analuminum workpiece, the cutting fluid is free of foam and insoluble oil soap, and pipelines of cutting equipment are free of blockage and corrosion.

Description

technical field [0001] The present application relates to the technical field of cutting fluids, in particular to a steel-aluminum combined water-based metal processing cutting fluid and a preparation method thereof. Background technique [0002] Cutting fluid is composed of various chemical additives and is an important industrial fluid for metal cutting. Compared with cutting oil, cutting fluid is diluted with water to a concentration of about 5% when used, which has good cooling performance, eliminates smoke, and is environmentally friendly and safe. Its excellent cooling, lubricating, cleaning and other properties are favored by the industry, and it overcomes the disadvantages of traditional soap-based emulsions that are easy to smell in summer, difficult to dilute in winter, and poor anti-rust effect. [0003] For materials with different processing properties, different cutting fluids are usually required due to their different corrosion mechanisms. For example, the ...
