Whitening agent for aluminum cell phone battery cover and preparation method of whitening agent

Abstract

The invention provides a whitening agent for an aluminum cell phone battery cover and a preparation method of the whitening agent. The preparation method comprises the following steps that firstly, under the normal temperature, the solid raw materials of sodium silicate, sodium gluconate, sodium citrate monohydrate, sodium benzoate and 1-hydroxyethanediphosphonic acid sodium salt are sequentially stirred and dissolved in deionized water, then liquid raw materials of triethanolamine and a bubble-free ampholytic surfactant are added and stirred uniformly, and transparent liquid is obtained; the die-cast aluminum cell phone battery cover can be cleaned through the transparent liquid, and the good cleaning effect is achieved; and the raw materials used in the product formula are all environmental-friendly raw materials, no environment controlled matter components exist, and the product is gentle in performance, environmentally-friendly, free of toxin, simple in manufacturing process, low in cost, free of flavor and good in effect, and discharge is free of pollution to the environment.

Description

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

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
