Description

The making method of decorative pattern of aluminium alloy plate

The present invention relates to a kind of material of construction, a kind of metal decorative material, specifically a kind of making method of decorative pattern of aluminium alloy plate.

Along with growth in the living standard, people are more and more higher to the room hall and furniture decoration effect of requirement, and high-grade aluminium alloy decoration plate progressively enters the decoration field.Existing common aluminum alloy decorative sheet mostly is a tabula rasa, and it is relatively more dull to make finishing material, but because aluminum metal is more active, and oxidation-resistance is relatively poor, the color and luster dimness is ugly year in and year out.In order to solve the deficiency of tabula rasa dullness, also there is the aluminium alloy decoration plate of a small amount of decorative pattern that punching to occur in the market.Form because its decorative pattern is punching, this has not only damaged the provide protection of surface decoration material to body, but also keeps away the deficiency of unavoidable self oxidation-resistance difference.

In view of there is above-mentioned deficiency in prior art, the objective of the invention is to disclose a kind of making method of decorative pattern of aluminium alloy plate, it is beautiful to use method of the present invention to produce clear patterns, and oxidation-resistance is strong, and is durable in use.

The making method of decorative pattern of aluminium alloy plate of the present invention realizes through the following steps:

A) aluminium alloy plate is placed on plain cloth buff polishing machine and polishes, make its surface smoothness reach minute surface;

B) aluminium alloy plate of step a gained is placed in 1～2% detergent warm water solution to clean removes its surperficial cream point;

C) select or design the making sheet of taking pictures behind the floral designs for use, on the aluminium alloy plate of step b gained, print floral designs with printing ink after making the silk screen web plate;

D) will produce aluminium alloy plate after floral designs and the seasoning and be coated with and spread the silicon dioxide powder that water is modulated into pasty state, and then be placed on hacking on the bristles wheel powder beater;

E) remove silicon dioxide powder on the steps d gained aluminium alloy plate with flushing with clean water;

F) aluminium alloy plate of step e gained being placed on concentration is to soak for 30～60 seconds in 3%～10% hydrofluoric acid aqueous solution, obtains being placed on behind the refined smooth canescence background color soaking in the Rinsing Area for 1～5 second;

G) to be placed on concentration be to remove removal ink in 2%～6% aqueous sodium hydroxide solution to the aluminium alloy plate that step f is obtained, and exposes true qualities, goes to adhere to thereon sodium hydroxide and oven dry with flushing with clean water again;

H) aluminium alloy plate that step g is obtained be placed on roller coating one bed thickness on the coating roller be 4～7 μ m be 20%～40% CALCIUM ACRYLATE varnish with the dimethylbenzene weaker concn, the constant temperature baking promptly got the aluminium alloy decoration plate finished product that is printed with floral designs in 40～60 minutes then.

Decorative pattern of aluminium alloy plate making method of the present invention is than following outstanding advantage of prior art tool and significant effect:

1. produced aluminium alloy plate clear patterns, Shu Ya, elegant in appearance, bright in color, soft;

2. durable in use, nondiscoloration, colour-fast, indeformable;

3. be not afraid of printing ink and soda acid chemical corrosion;

4. can satisfy fire prevention, waterproof, antifreeze requirement.

Below in conjunction with specific embodiment the present invention is described in more detail,, grasps better and implement technique means of the present invention so that the public fully understands technical solution of the present invention.
