Problems solved by technology

Since the color film and the steel plate are fixed by bonding, after a long time of use, the color film and the steel plate are prone to film separation; while the surface of the pre-coated color steel plate is prone to fog, and the sharpness of image is poor

Embodiment 1

[0039] Embodiment 1: A kind of high-definition printing color plate, including a metal layer, the upper surface of the metal layer is sequentially arranged with a first chemical treatment layer, a second chemical treatment layer, and an antirust primer layer from the surface of the metal layer , middle coating layer, first texture layer, second texture layer, third texture layer, varnish protection layer and protective film layer; the lower surface of the metal layer is arranged with the first chemical treatment layer, the second Two chemical treatment layers, anti-rust back primer layer and back paint layer.

[0040] The above high vividness printing color plate is made according to the following method:

[0041] S1. The metal layer is a hot-dip galvanized sheet with a thickness of 1.2 mm and a surface roughness of 0.8 μm; the metal layer is pre-degreased, washed and air-dried;

[0042] S2. Chemical treatment of the surface of the metal layer: the first chemical treatment la...

Abstract

The invention relates to a printed color coated sheet with high distinctness of image and a preparation method thereof. The printed color coated sheet with high distinctness of image mainly comprisesa metal layer; a chemical treatment layer, a floating coat and a varnish protective layer are sequentially arranged on the upper surface of the metal layer from the surface of the metal layer; and a chemical treatment layer and a back paint layer are sequentially arranged on the lower surface of the metal layer from the surface of the metal layer. According to the printed color coated sheet, metallayer pretreatment and metal layer surface chemical treatment are sequentially carried out on the surface of the metal layer, the surface of the metal layer is coated with an anti-corrosive primer layer and a back primer layer, the upper surface of the metal layer is coated with the floating coat, the upper surface of the metal layer is provided with a texture layer through gravure printing, thesurface of the metal layer is coated with the varnish protective layer, and a protective film layer adheres to the upper surface of the metal layer. The printed color coated sheet treated by the process has the advantage of being relatively high in distinctness of image.

Description

technical field [0001] The invention relates to the field of composite metal plates, in particular to a high-definition printing color plate and a preparation method thereof. Background technique [0002] At present, architectural decoration and the outer periphery of household appliances are usually decorated with metal or non-metallic layers. Taking household appliances as an example, the outer periphery of household appliances is usually decorated with glass or color-coated steel. high-end home appliances. However, the sharpness of image on the surface of the color-coated steel plate is poor, and it is mostly used on the surface of low-end household appliances. [0003] In order to improve the sharpness of the color-coated steel plate, it is usually divided into a color film-coated color plate and a pre-coated color-coated steel plate. Among them, the color film coated steel plate is usually coated with an aluminum foil color film on a substrate that has been baked at a...
