AI Technical Summary

Problems solved by technology

However, the existing polishing agents have problems such as quick rust return, narrow applicable metal types, and incomplete cleaning. Many polishing agents contain fluorine compounds or phosphorus-containing compounds, which pollute the environment.
Moreover, the commonly used polishing agents on the market are mainly solid, that is, polishing paste. This product is labor-intensive when used, and the surface treatment of fine structures is not complete enough.

Abstract

The invention provides a method for preparing a metal polishing solution. The method comprises the following steps: (1) preparing to obtain chitosan / attapulgite composite particles; (2) weighing the following materials in parts by weight: 1-5 parts of silica powder, 2-5 parts of spherical silicon resin powder, 4-8 parts of chitosan / attapulgite particles, 3-6 parts of cysteine, 1-2 parts of alkylphenol ethoxylates, 2-5 parts of citric acid, 1-2 parts of cocoyl diethanol amine, 1-3 parts of sodium cocoyl glutamate, 1-5 parts of polyaspartic acid, 2-6 parts of tallow ammonium polyoxyethyl ene ether and 80-120 parts of water; and (3) mixing the silica powder, the spherical silicon resin powder and the chitosan / attapulgite particles ball-milling, adding the cysteine, alkylphenol ethoxylates, citric acid, cocoyl diethanol amine, sodium cocoyl glutamate, polyaspartic acid, tallow ammonium polyoxyethyl ene ether and water, and uniformly mixing and stirring, thereby obtaining the metal polishing solution. The polishing solution disclosed by the invention is excellent in effects and less in environmental pollution.

Description

technical field [0001] The invention relates to a polishing liquid, in particular to a metal polishing liquid. Background technique [0002] There are many methods and means for metal surface treatment, such as electroplating, electrophoresis, chemical treatment, surface polishing, etc. Chemical polishing is a kind of chemical corrosion under special conditions. It is a metal processing process that makes the metal surface smooth and bright by controlling the selective dissolution of metals. Effect and maintain clear characters and patterns, which put forward higher requirements for chemical polishing process, including chemical polishing liquid. After metal utensils are processed, a layer of oil or other chemical preparations are usually attached to the surface. After the utensils are used for a period of time, the corrosion of the use environment will cause rust on the surface. In order to look beautiful and prolong the service life, special metal cleaning agents or polis...
