Novel composite metal polishing fluid and preparation method thereof

Abstract

A disclosed novel composite metal polishing fluid is characterized by being prepared from the following raw materials in parts by weight: 11-13 parts of cerium oxide, 2-4 parts of graphene oxide, 7-9 parts of rapeseed oil, 1-2 parts of stannous octoate, 4-6 parts of polyoxyethylene sorbitan fatty acid ester, 3-5 parts of polyoxyethylene castor oil, 4-6 parts of urea, 2-4 parts of citric acid, 4-6 parts of emulsified silicone oil, 5-7 parts of an auxiliary agent, and 300 parts of deionized water. The prepared mixed polishing fluid is safe, non-toxic and reasonable in formula. Through the cooperation of the added surfactant and the abrasive, the polishing effect is improved, preferential adsorption is realized, and a long-term easily-cleaned physical adsorption surface is formed. By adding the auxiliary agent, the polishing fluid has good dispersity, lubricity and film-forming property, and is capable of forming an air-obstructing layer on a workpiece surface to prevent air from corroding a metal surface. The polishing fluid is capable of satisfying the polishing processing requirements of various products and parts, and helps to improve the polishing efficiency, cleaning effect, surface precision and the like.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a novel composite metal polishing liquid and a preparation method thereof. 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 beautif...

Problems solved by technology

After the 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, due to the corrosion of the environment, rust will appear on the surface. In order to look beautiful and prolong the service life, special metal cleaning agents or polishing are often used However, the existing polishing agent products have quick rust return, narrow applicable metal types, incomplete cleaning, weak polishing performance, easy to produce odor, dust on the surface after polishing, and easy to rust after polishing. Polishing liquid is easy to rot and other problems, the present invention is the technical improvement of the mixed polishing liquid
