Reactive type water-based metal grinding fluid and preparation method thereof

Abstract

The invention relates to a water-based metal grinding fluid and a preparation method thereof. The water-based metal grinding fluid comprises the components of sodium tetraborate, boric acid, a solvent, triethanolamine, a sodium salt with slow release function, a corrosion inhibitor, a water-based defoamer, preservative and deionized water. The grinding fluid greatly improves the machining precision and the surface finish quality of a workpiece, and effectively eliminates surface sewages of the workpiece. Through practical application tests by many enterprises, the use effect of the grinding fluid achieves the engineering level of an imported fully synthetic water-based grinding fluid, and the water-based metal grinding fluid can be used for effectively replacing an imported high-grade fully synthetic water-based metal grinding fluid, thereby greatly lowering the production cost of grinding machining.

Description

technical field [0001] The invention belongs to the field of metal grinding fluid, in particular to a reactive water-based metal grinding fluid and a preparation method thereof. Background technique [0002] Mechanical cutting and polishing usually require cutting fluid or grinding fluid to assist cutting and polishing. For precision grinding of hard materials, especially crystals, grinding fluid composed of hard material particles dispersed in oil is traditionally used. The use of oily grinding fluid makes it difficult to clean the surface of the workpiece and requires pickling, which not only wastes resources, but also pollutes the environment and has certain toxic and side effects. [0003] Through searching, I found a water-quality water-suspension grinding fluid (CN101161800), which is based on water, and under the action of anionic surfactants, the silicon carbide powder or / and diamond powder with a fineness of ≥1200 mesh is uniformly dispersed , forming a water-suspe...

Problems solved by technology

The suspension is based on water, although the viscosity can be adjusted, which improves the cutting efficiency to a certain extent, but it is a suspension, not water-based in the true sense
