Degreasing agent

Abstract

The invention discloses a degreasing agent, which comprises the following components in parts by weight: 1 to 5 parts of fatty acid methyl ester ethoxylate sodium sulfonate, 3-9 parts of sodium metasilicate, 1-7 parts of potassium hydroxide, 2-10 parts of potassium carbonate, 10-13 parts of benzotriazole, 5-10 parts of tetramethylammonium hydroxide, 10-12 parts of citric acid, 1-5 parts of straight-chain imidazoline amide, 15-20 parts of an auxiliary and 70-100 parts of deionized water. The degreasing agent provided by the invention can wet the metal surface in the cleaning process, has good permeation, dispersion, solubilization and emulsification effects, can effectively remove grease and dirt and reduce the adhesion of oil stains, and is low in corrosivity and few in residue.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy surface treatment, in particular to a degreasing agent. Background technique [0002] In order to overcome the defects of aluminum alloy surface hardness, wear resistance, etc., expand the scope of application, and prolong the service life, surface treatment technology has become an indispensable part of the use of aluminum alloys, and anodizing technology is the most widely used and most successful . Anodic oxidation refers to the electrochemical oxidation of metals or alloys. It is the formation of a layer of aluminum and its alloys on aluminum products (anodes) under the action of an applied current under the corresponding electrolyte and specific process conditions. Oxidation process. Anodizing, if not otherwise specified, usually refers to sulfuric acid anodizing. In the oxidation treatment process of aluminum alloy, it is necessary to use a degreasing agent to remove the grease imp...

AI Technical Summary

Problems solved by technology

In the oxidation treatment process of aluminum alloy, it is necessary to use a degreasing agent to remove the grease impurities on the metal surface. The quality of the degreasing agent is directly related to the effect of the subsequent surface treatment of the aluminum alloy. Therefore, it is very necessary and key to improve the research on the degreasing agent. , but there is still a lack of degreasing agents with good degreasing effect on the market
