Problems solved by technology

[0003] The surface of aluminum metal will be oxidized to form a dense oxide film. At present, electrolysis is used to form an oxide film on the surface. The metal oxide film changes the surface state and properties, such as surface coloring, improves corrosion resistance, and enhances wear resistance. and hardness, to protect the metal surface, but in the process of anodizing, there will be residual acidity, and the common method will be to spit out the acid through the surface conditioner, but the existing surface conditioner is not effective in spit out the acid, so that there are more acid residues, resulting in product failure Performance drop

Embodiment Construction

[0012] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0013] In the embodiment of the present invention, a surface conditioner, the surface conditioner is composed of the following components by mass percentage: sulfamic acid is 50 to 60%, sodium acetate is 20 to 30%, niacin is 15% to 25%, bicarbonate Sodium is 1 to 9%.

[0014] Specifically, the sulfamic acid is 50 to 56%; the mass percentage of sulfamic acid is not less than 50%, and the product with a mass percentage of sulfamic acid lower than 50% will be corroded.

[0015] Specifically, the sodium acetate is 22 to 26%; sodium ace...

Abstract

The invention discloses a conditioner for metal surface. The conditioner for metal surface is composed of the following components in percentage by mass: 50 to 60% of sulfamic acid, 20 to 30% of sodium acetate, 15 to 25% of nicotinic acid and 1 to 9% of sodium bicarbonate; and after anodizing a product, acid can be spit out more effectively, thereby improving the corrosion resistance, enhancing the wear resistance and hardness, and protecting the metal surface.

Description

technical field [0001] The invention relates to the field of aluminum surface treatment, in particular to a surface conditioner. Background technique [0002] In order to keep the appearance of the aluminum alloy of some appearance parts, the organic solvent is used as the medium during anodic oxidation, so as to expand the application range and prolong the service life, and the anodic oxidation technology is the most widely used and most successful at present, and the surface treatment technology has become the aluminum alloy. An indispensable link in the use of alloys. [0003] The surface of aluminum metal will be oxidized to form a dense oxide film. At present, electrolysis is used to form an oxide film on the surface. The metal oxide film changes the surface state and properties, such as surface coloring, improves corrosion resistance, and enhances wear resistance. and hardness, to protect the metal surface, but in the process of anodizing, there will be residual acidi...
