Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The present invention proposes a new substitute for the current color steel plate. The composite film of the present invention directly uses embossed PET composite color film to replace the current aluminum foil color film or PET+PVC laminated color film. The structure of the PET composite color film: the color layer is on the bottom of the PET film, and the pattern layer is pressed on the top.

[0036] refer to figure 1 In the cross-sectional structure of the color steel plate shown, the structure from top to bottom is: protective film 6, pattern layer 52, PET film 51, color layer 53, glue layer 4, chemical treatment layer 3, substrate 1, back paint 2. The substrate 1 is a stainless steel plate. The pattern layer 52, the PET film 51 and the color layer 53 constitute the embossed PET composite color film 5. By rolling the pat...

Abstract

The invention provides an embossed PET (Polyethylene Terephthalate) laminated colorful steel plate which comprises a base plate, wherein the upper surface of the base plate is a chemical processing layer, the back surface of the base plate is a back paint layer, the chemical processing layer is coated with a glue water layer, and an embossed PET compound colorful film is arranged on the glue water layer. The invention further provides a production method of the embossed PET laminated color steel plate. The production method comprises the following basic processes: uncoiling the base plate; pretreating the base plate; coating the steel plate with back paint; coating glue water in front of the steel plate; laminating in front of the steel plate; and laminating a protection film in front; and coiling. According to the embossed PET laminated colorful steel plate, a metal effect of a stainless steel plate is shown, the metal texture on the surface of the plate is improved, the problems of high cost and pollution of products are effectively solved, and the profitability of the products is improved.

Description

[0001] technical field [0002] The invention belongs to the field of metal plates used for housings of household appliances, interior and exterior decoration of buildings, etc., and in particular relates to an embossed PET-coated color steel plate and a production method thereof. Background technique [0003] The existing surface embossed film-coated color steel plate is to paste aluminum foil-like color film or PET+PVC laminated color film on the substrate after high-temperature baking (the surface of the substrate is coated with glue). The surface of the aluminum foil color film is embossed with patterns, but the current use of aluminum foil color film is mainly imported, and the purchase cost is relatively high. The adhesion between PET+PVC laminated color film layers is risky and contains PVC materials, so the product is not environmentally friendly. Contents of the invention [0004] The purpose of the present invention is to provide a new type of embossed PET-coate...
