Aqueous working fluid for highlight surface of aluminum alloy shell, and preparation method and application method of aqueous working fluid

Abstract

The embodiment of the invention discloses an aqueous working fluid for a highlight surface of an aluminum alloy shell. The raw materials of the working fluid comprise an isomeric alkane acid aluminum material protective agent, a nonionic emulsifying agent, an aqueous extreme-pressure lubricant, boric acid, triethanolamine, an amide antirust agent, a monobutyl ether coupling agent, a hard water resisting agent, an antifoaming agent and distilled water. The raw materials of the aqueous extreme-pressure lubricant comprise the triethanolamine, dimmer acid, self-emulsifying ester and the distilled water, wherein the content of the distilled water is two times that of the triethanolamine; the weight ratio of the triethanolamine to the dimmer acid to the self-emulsifying ester is 100:30:40. The aqueous working fluid for the highlight surface of the aluminum alloy shell is high in lubricating performance, antirust performance, cleaning performance and anti-saponification performance; bright lines and white points can not be easily generated on the highlight surface of an aluminum material. All indicators of 5 percent of diluent accord with or exceed GB6144-2010 related indicators. A fire hazard and an irritating smell are can not be easily generated in an operation site. The working fluid is harmless and non-irritant to the skin, and the working efficiency is improved. Purified water can be directly used as a cleaning agent to replace a solvent, the volatilization and the emission of the solvent are reduced, environmental protection is facilitated, the working environment is purified, the working fluid is pollution-free, and the economical cost is saved.

Description

technical field [0001] The invention relates to the technical field of lubricating and antirust cleaning for metal processing, in particular to an aqueous processing fluid for high-gloss surfaces of aluminum alloy shells, a preparation method and a use method thereof. Background technique [0002] Aluminum alloy casing is a variety of casings made of aluminum alloy. Because of its convenient processing, high flexibility and high grade, it can effectively increase the added value of products and can be widely used in the electronics industry. It generally includes aluminum profile casings and aluminum alloy casings. Die-cast housing. The high-gloss surface on the aluminum alloy shell is processed by high-speed cutting, which is very bright like a mirror. However, when using traditional water-based cutting fluid, there are many problems: the tool wears very fast, the tool holder is seriously rusted, especially the frequent generation of bright lines and white spots, which ser...

Problems solved by technology

However, when using traditional water-based cutting fluid, there are many problems: the tool wears very fast, the tool holder is seriously rusted, especially the frequent generation of bright lines and white spots, which seriously affects the subsequent high-gloss surface anodizing process , the low pass rate of products has always been a technical problem that plagues processing; while using oil-based cutting oil, although the processing effect can be achieved, the subsequent cleaning requires a large amount of solvent-based cleaning agent, which causes great pollution to the environment and is not environmentally friendly. also increases the economic cost

[0003] Therefore, there is a need for a high-gloss surface water-based machining fluid for aluminum alloy shells with excellent lubricating and cleaning properties to solve the problem of surface oxidation during the processing of high-gloss aluminum materials; to solve the corrosion of black metal tool jackets during the processing of high-gloss surfaces of aluminum materials problems; solve the problem of bright lines and white spots on high-gloss surfaces; and solve environmental and safety issues
