Full-synthetic water-based high-silicon aluminum alloy cutting fluid and preparation method and application method thereof

Abstract

The invention discloses full-synthetic water-based high-silicon aluminum alloy cutting fluid and a preparation method and an application method thereof. The cutting fluid is made from aluminum protectant, caprylic-capric acid blend, water-based extreme-pressure lubricant, boric acid, glycerol, cationic quaternary ammonium aluminum scrape settling agent, triethanolamine, dicarboxylate-based compound rust inhibitor, monobutyl ether coupler, hard water resister, defoamer, and distilled water. By using an environment-friendly full synthesis formula, cleaning and settling performances of the cutting fluid are enhanced. The environment-friendly special water-based extreme-pressure lubricant replaces traditional synthetic esters, and accordingly lubricating performance and cleaning performance of the cutting fluid are guaranteed to be stable for a long period of time. The cutting fluid also protects well nonferrous metals and ferrous metals. The environment-friendly aluminum protectant is used, and accordingly surface corrosion of aluminum material in processing of high-silicon aluminum alloy is avoided.

technical field [0001] The invention relates to the technical field of lubricating and rust-proof cleaning for metal processing, in particular to a fully synthetic water-based high-silicon aluminum alloy cutting fluid, a preparation method and a use method thereof. Background technique [0002] High-silicon aluminum alloys are widely used due to their advantages of high strength, high wear resistance, low expansion coefficient and good casting performance. However, the common problem is that the machining of high-silicon aluminum alloys is more difficult than ordinary aluminum alloys, and cutting lubricants are required to have high lubricating extreme pressure performance and outstanding cleaning performance.

Problems solved by technology

However, the common problem is that the cutting process of high-silicon aluminum alloys is more difficult than ordinary aluminum alloys, and cutting lubricants are required to have high lubricating extreme pressure performance and outstanding cleaning performance.

Although the traditional extreme pressure emulsion and semi-synthetic processing fluid can meet the lubricating performance of processing, the cleaning performance is poor; because the silicon content of high-silicon aluminum alloy reaches more than 10%, in the case of lack of cleaning performance, silicon and aluminum The residual cutting fluid on the surface of the alloy is prone to chemical reactions, resulting in white spots and dark lines corrosion on the aluminum surface, resulting in a decline in product performance or even scrapping

At the same time, since the emulsion is easy to rancid, it will accelerate the corrosion of silicon aluminum alloy

[0003] Therefore, there is a need for a cutting fluid used in the processing of silicon-aluminum alloys. The lubricating performance, corrosion resistance and cleaning performance can be matched for a long time to solve the problem of aluminum surface corrosion in the processing of high-silicon aluminum alloys; to solve the problem of high-silicon aluminum alloy processing Difficult cleaning of lubricating fluid; solve the environmental protection problem of waste liquid discharge
