Abstract
A wood grain-like aluminum veneer surface treatment process. Relates to a surface treatment process, in particular to a surface treatment process of an aluminum plate. Provides a wood grain imitating aluminum veneer surface treatment process with more vivid wood grains and long retention time. The method comprises the following steps: a first cleaning step, cleaning residues and an oxide layer on the surface of the aluminum veneer; etching, namely etching wood grains on the surface of the aluminum plate; a secondary cleaning step, cleaning residues on the surface of the aluminum plate in the etching process; and a painting step, painting the surface of the aluminum plate, covering the surface of the aluminum plate to form wood grain lines, and finishing. Etch out the wood grain line through the etching on aluminum plate surface, just can directly simulate out the wood grain through the line when reusing paint like this and coating, actual wood grain is direct etching on aluminum plate when using like this, and the wood grain line is more wear-resisting, and life is longer.
Description
Technical Field
The invention relates to a surface treatment process, in particular to a surface treatment process of an aluminum plate.
Background
At present, wood grain-like aluminum veneers are generally formed by directly drawing wood grain shapes on the surfaces of aluminum plates through paint, the surfaces are smooth and have no hand feeling after the aluminum veneers are touched by hands with better visual effects, the wood grain fidelity is low, and the wood grain paint is seriously abraded along with long service time. .
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides the surface treatment process of the wood-grain-imitated aluminum veneer, which has more vivid wood grains and long retention time.
The invention is realized by adopting the following technical scheme: the surface treatment process of the wood grain-like aluminum veneer comprises the following steps:
a first cleaning step, cleaning residues and an oxide layer on the surface of the aluminum veneer;
etching, namely etching wood grains on the surface of the aluminum plate;
a secondary cleaning step, cleaning residues on the surface of the aluminum plate in the etching process;
and a painting step, painting the surface of the aluminum plate, covering the surface of the aluminum plate to form wood grain lines, and finishing.
And the etching step is acid washing etching, a coating which does not react with the acid liquor is covered on the surface of the aluminum plate, the wood grain position on the aluminum plate is exposed, the aluminum plate is wholly immersed in the acid liquor for 0.5h, and the aluminum plate with the wood grain on the surface is obtained after the aluminum plate is taken out and the coating is removed.
And the cleaning agent used in the primary cleaning step is acid liquor, the aluminum plate is immersed in the cleaning agent for 0.5h, and after being taken out, the aluminum plate is washed by pure water for 0.5h, so that the oxide layer and the residual cleaning agent on the surface are washed away.
And the cleaning agent used in the secondary cleaning step is alkali liquor, the aluminum plate is immersed in the cleaning agent for 0.5h, and after being taken out, the aluminum plate is washed by pure water for 0.5h, so that the oxide layer and the residual cleaning agent on the surface are washed away.
Compare prior art, etch out the wood grain line through the etching on aluminum plate surface, just can directly simulate out the wood grain through the line when reusing paint like this and coating, like this actual wood grain is direct etching on aluminum plate when using, and the wood grain line is more wear-resisting, and life is longer.
Detailed Description
The present invention is further described below with reference to specific embodiments, and it should be noted that, without conflict, any combination between the embodiments or technical features described below may form a new embodiment.
The wood grain-like aluminum veneer surface treatment process comprises the following steps:
a first cleaning step, cleaning residues and an oxide layer on the surface of the aluminum veneer;
etching, namely etching wood grains on the surface of the aluminum plate;
a secondary cleaning step, cleaning residues on the surface of the aluminum plate in the etching process;
and a painting step, painting the surface of the aluminum plate, covering the surface of the aluminum plate to form wood grain lines, and finishing.
Etch out the wood grain line through the etching on aluminum plate surface, just can directly simulate out the wood grain through the line when reusing paint to coat like this, actual wood grain is direct etching on aluminum plate when using like this, and the wood grain line is more wear-resisting, and life is longer.
And the etching step is acid washing etching, a coating which does not react with the acid liquor is covered on the surface of the aluminum plate, the wood grain position on the aluminum plate is exposed, the aluminum plate is wholly immersed in the acid liquor for 0.5h, and the aluminum plate with the wood grain on the surface is obtained after the aluminum plate is taken out and the coating is removed.
And the cleaning agent used in the primary cleaning step is acid liquor, the aluminum plate is immersed in the cleaning agent for 0.5h, and after being taken out, the aluminum plate is washed by pure water for 0.5h, so that the oxide layer and the residual cleaning agent on the surface are washed away. And (3) pickling the surface of the aluminum plate with acid liquor to provide a clean plate for the subsequent steps.
And the cleaning agent used in the secondary cleaning step is alkali liquor, the aluminum plate is immersed in the cleaning agent for 0.5h, and after being taken out, the aluminum plate is washed by pure water for 0.5h, so that the oxide layer and the residual cleaning agent on the surface are washed away. On the one hand, the residual acid liquor is neutralized by alkali liquor, and on the other hand, the residual of the coating is cleaned by alkali liquor.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
