Embodiment 1

[0032] The present invention imitates the stainless steel drawing coated aluminum plate, with reference to figure 1 , including an alloy aluminum substrate 3, on the top (front side) of the alloy aluminum substrate 3 are a wire drawing layer 4, a first passivation layer 5 and a top coat 6; Passivation layer 2 and back paint layer 1.

[0033] Wherein, the alloy aluminum substrate 3 is a 3004H24 aluminum plate, and the top coat 6 further includes a protective layer 7, and the protective layer 7 is a polyethylene protective film.

[0034] The method of manufacturing the stainless steel wire drawing coated aluminum plate of this embodiment is as follows: the alloy aluminum base material is subjected to wire drawing, pre-treatment degreasing, chromization, and then high-temperature baking after coating the top coat to form the imitation stainless steel wire drawing coating of the present invention. Layer aluminum plate, among which, the top coat is polyethylene terephthalate resin...

Embodiment 2

[0040] The principle and setting of this embodiment are the same as those of Embodiment 1, the difference is that the alloy aluminum substrate 3 is 5052H24 in the aluminum 5 series, and the topcoat layer 6 is polyethylene terephthalate provided by Beike Industrial Coatings Shanghai Co., Ltd. Alcohol ester resin colored transparent varnish (model BD2700075), which is obtained by modifying the gloss, impact resistance, weather resistance, flexibility and solvent resistance according to the standard; the protective layer 7 is a polyethylene protective film, and the wire drawing is made of Short brushed effect, when baking at high temperature, the temperature is 225~235°C, and the baking time is 70 seconds.

[0041] According to the test standard and method of Example 1, the properties of the imitation stainless steel wire-drawn coated aluminum plate prepared in this example were tested, and the results are shown in Table 3.

Embodiment 3

[0045] The principle and setting of this embodiment are the same as those of Embodiment 1, the difference is that the alloy aluminum substrate 3 is 7075 in the aluminum 7 series, and the top coat 6 is polyethylene terephthalate resin provided by PPG Industries Co., Ltd. The color transparent paint (model APBC3250) is obtained by modifying the gloss, impact resistance, weather resistance, flexibility and solvent resistance according to the standard. The protective layer 7 is the anti-fingerprint layer, and the drawing adopts random drawing effect. The temperature during high-temperature baking is 200-230° C., and the baking time is 90 seconds.

[0046]According to the test standard and method of Example 1, the properties of the imitation stainless steel wire-drawn coated aluminum plate prepared in this example were tested, and the results are shown in Table 4.

[0047] Table 4 The performance parameters of Example 3 imitation stainless steel wire drawing coated aluminum plate ...

Abstract

The invention relates to an imitation stainless steel drawing coating aluminum plate and a manufacturing method thereof and belongs to the technical field of aluminum alloy surface treatment. In the imitation stainless steel drawing coating aluminum plate provided by the invention, a drawing layer, a first passivation layer and a surface coating are sequentially arranged above an aluminum alloy base material, and a second passivation layer and a primer layer are sequentially arranged below the aluminum alloy base material. The manufacturing method of the imitation stainless steel drawing coating aluminum plate comprises: drawing, pre-treatment degreasing and passivating an aluminum alloy substrate, coating print on the aluminum alloy substrate and roasting the same at a high temperature to form the imitation stainless steel drawing coating aluminum plate in the invention. The imitation stainless steel drawing coating aluminum plate manufactured by the scheme of the invention overcomes the defects of single tone and cold feeling of the stainless steel and has the metal drawing effect of the stainless steel, the strength is high and the manufacture is convenient, so that the imitation stainless steel drawing coating aluminum plate can be used as indoor decorative sheets in such fields as hotel, exhibition hall, kitchen and cabinet, etc.

Description

technical field [0001] The invention relates to a brushed coated aluminum plate imitating stainless steel and a manufacturing method thereof, belonging to the technical field of aluminum alloy surface treatment. Background technique [0002] The price of existing stainless steel has also increased greatly in recent years due to the sharp rise in the price of nickel. The use of stainless steel as raw material has led to a sharp increase in the cost of raw materials for the production of household appliances, making it difficult to increase the price of finished products accordingly, and the existing stainless steel surface treatment technology can only achieve the natural color of stainless steel with brushed and frosted effects or polished and painted black paint The expensive black titanium gold produced has a single and cold surface effect, and the color options available to customers are limited. The coated alloy aluminum sheet is one of the widely used materials in the ...
