Preparation method of defoaming-agent-free water-based cutting fluid and water-based cutting fluid

Abstract

The invention discloses a preparation method of a defoaming-agent-free water-based cutting fluid and the defoaming-agent-free water-based cutting fluid. A lubricant, an antirust agent, a dispersing agent, a penetrating agent, an extreme pressure agent and water are respectively weighed according to preset mass percentage; the water, the lubricant, the rust remover, the dispersant and the extreme pressure agent which are weighed are added into a preset reaction kettle, and stirred for a preset first time, so that the lubricant, the rust remover, the dispersant and the extreme pressure agent are fully dissolved to obtain a first solution; and the penetrant is added into the first solution, and stirred for a preset second time to obtain the defoaming-agent-free water-based cutting fluid. The water-based cutting fluid solves the technical problems that when a defoaming agent is added into an existing water-based cutting fluid, the defoaming agent is difficult to dissolve in water and is often layered in the cutting fluid, more foam is caused by failure of the defoaming agent along with the increase of the use frequency, and the production cost is additionally increased by adding an organic solvent into the cutting fluid.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to a method for preparing a defoamer-free water-based cutting fluid and the defoamer-free water-based cutting fluid. Background technique [0002] In the process of workpiece processing, it is usually necessary to cut the workpiece, so as to improve the surface roughness of the workpiece and ensure the machining accuracy of the workpiece, so that the workpiece can achieve the best economic effect. In the process of cutting the workpiece, in order to reduce the cutting force during cutting and take away the heat generated in the cutting area in time to reduce the cutting temperature, so as to improve the tool durability and ensure the overall production efficiency, cutting fluid has to be used. Cutting fluids are mainly divided into oil-based cutting fluids and water-based cutting fluids. Among them, oil-based cutting fluids have good lubricating performance but poor cooling perform...

Problems solved by technology

[0005] The main purpose of the present invention is to propose a method for preparing a water-based cutting fluid without a defoamer and a water-based cutting fluid without a defoamer, aiming at solving the problem of adding a defoamer to the water-based cutting fluid in the past, because the defoamer is not easy Soluble in water, often forms stratification in cutting fluid, and, as the number of uses increases, the defoamer will fail to cause more foam, and adding organic solvents to cutting fluid will also increase the technical problems of production costs
