Whitening agent for aluminum mobile phone battery cover and preparation method thereof

Abstract

The invention provides an aluminum mobile phone battery cover whitening agent and a preparation method thereof, which is prepared as follows: at room temperature, the above-mentioned solid raw materials: sodium silicate, sodium gluconate, sodium citrate monohydrate, sodium benzoate The raw materials of sodium hydroxyethylidene diphosphonate are stirred and dissolved in ion-free water, and then the liquid raw materials triethanolamine and non-foaming amphoteric surfactant are added and stirred evenly to obtain a transparent liquid. It can clean the die-casting aluminum mobile phone battery cover and has a good cleaning effect. The raw materials used in the product formula are all environmentally friendly raw materials, and there are no environmentally controlled substances. The product performance is mild, environmentally friendly and non-toxic, and the production process is simple. Low cost, no smell, good effect, no pollution to the environment.

Description

[0001] Technical field: [0002] The invention belongs to the field of industrial cleaning agents for fine chemicals, and relates to an aluminum whitening agent and a preparation method, and in particular to an aluminum mobile phone battery cover whitening agent and a preparation method thereof. [0003] Background technique: [0004] Whitening agent is a kind of cleaning agent. At present, there are many types of cleaning agents on the market, and there are countless cleaning agents used in daily life, but there are not many cleaning agents or whitewashing agents used in aluminum and its alloys. , There are fewer cleaning and whitening agents to be used in aluminum mobile phone battery cover whitening agents. Such as the cleaning of stainless steel stamping oil, foreign cupronickel stamping oil, automobile tubing rolling oil, etc. When using existing cleaning agents or metal cleaning agents such as aluminum alloys to whitewash precision metal parts, the surface of aluminum metal af...

AI Technical Summary

Problems solved by technology

When using existing cleaning agents or metal cleaning and whitening agents such as aluminum alloys to whiten precision metal parts, the surface of the aluminum metal after cleaning is insufficient in brightness and cleanliness, and is prone to yellowing; and for high-silicon die-casting aluminum After whitening, blackening, black skin and graying often appear on the surface of high-silicon die-cast aluminum
