Polishing fluid for polishing metal surfaces and preparation method thereof

Abstract

A disclosed polishing fluid for polishing metal surfaces is characterized by being prepared from the following raw materials in parts by weight: 1-2 parts of diethanolamine, 2-3 parts of ethanolamine, 2-4 parts of lauryl diethanolamide, 3-4 parts of hydroxy propyl cellulose, 3-5 parts of 2-(2-methoxyethoxy)ethanol, 2-4 parts of polyoxypropylene polyoxyethylene propylene glycol ether, 10-15 parts of nanometer aluminium oxide, 1-2 parts of gelatin, 1-2 parts of methionine, 5-7 parts of an auxiliary agent, and 300 parts of deionized water. The prepared polishing fluid is safe, non-toxic, good in polishing performance, uniform, high in luster and short in polishing time. By adding methionine, the polishing fluid has good corrosion inhibition effect. By adding the auxiliary agent, the polishing fluid has good wear resistance, dispersity, lubricity and film-forming property, and is capable of avoiding air corrosion under the synergic effect of a corrosion inhibitor. The polishing speed is stable, and the polishing fluid is capable of reducing environmental pollution, and is suitable for polishing of metal surfaces, and especially suitable for steel surfaces.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a polishing liquid for metal surface polishing and a preparation method thereof. Background technique [0002] 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 polishing are often used. However, existing polishing agent products have the problems of quick rust return, narrow applicable metal types, and incomplete cleaning. Contents of the invention [0003] The purpose of the present invention is to provide a polishing liquid for metal surface polishing and a preparation method thereof. [0004] In order to realize the purpose of the present invention, the present invention is implemented thro...
