Problems solved by technology

[0002] In the color-coating industry in my country for more than 20 years, the color-coated stainless steel sheets produced have bright and diverse colors. Because most of the color-coated coatings of color-coated stainless steel at this stage have insufficient adsorption force, they are easy to fall off or change color. At the same time, this Insufficient anti-rust treatment of similar stainless steel plates, easy to corrode and rust

Embodiment Construction

[0014] Embodiments of the present invention will be described below in conjunction with the accompanying drawings and preferred embodiments.

[0015] see figure 1 As shown in combination, a new type of stainless steel color-coated steel plate includes a stainless steel substrate 1, and the upper surface of the stainless steel substrate 1 is covered with a protective layer 7, a passivation layer 5, a laser layer 4, a color coating layer 3, and a hot-melt adhesive layer in sequence. 2 and pickling layer 6, the color coating 3 includes a front topcoat 3-1 and a front primer 3-2, the stainless steel substrate 1 is sprayed with an atomized layer 8 on both sides, the The pickling layer 6 is obtained by removing the surface oxide layer by soaking the pickling solution in hot rolling. The pickling solution can be hydrochloric acid and sulfuric acid, and the hot melt adhesive layer 2 is evenly applied on the pickling layer 6 by a roller. On the surface, the hot melt adhesive layer 2 i...

Abstract

The invention discloses a novel stainless steel color-coated steel plate which comprises a stainless steel base plate, the upper surface of the stainless steel base plate is sequentially covered with a protective layer, a passivation layer, a laser layer, a color coating layer, a hot melt adhesive layer and an acid pickling layer, the color coating layer comprises front finish paint and front primer, and atomization layers are sprayed on the front side and the back side of the stainless steel base plate. The stainless steel base plate is protected through the atomization layers, and ethylene glycol is used for cleaning the surface of stainless steel, so that the paint adhesive force is better; the corrosion resistance of the stainless steel base plate is good due to the phosphate, the adhesive force of the color coating layer is further enhanced through the hot melt adhesive layer, the color coating layer is more durable in paint adhesive force, the corrosion resistance and rust resistance of the surface of the stainless steel base plate are further better due to the protective layer and the passivation layer, and the novel stainless steel color-coated steel plate is more suitable for being popularized on the market.

Description

technical field [0001] The invention relates to the field of steel plate printing, in particular to a novel stainless steel color-coated steel plate. Background technique [0002] In the color-coating industry in my country for more than 20 years, the color-coated stainless steel sheets produced have bright and diverse colors. Because most of the color-coated coatings of color-coated stainless steel at this stage have insufficient adsorption force, they are easy to fall off or change color. At the same time, this The anti-rust treatment of similar stainless steel plates is insufficient, and it is easy to corrode and rust. Contents of the invention [0003] The object of the present invention is to provide a novel stainless steel color-coated steel plate to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A new type of stainless steel colo...
