Embodiment 1

[0036] Embodiment 1: A kind of composite film color plate, including steel plate layer, steel plate layer is arranged with prepainted paint layer, adhesive layer, color coating layer, high extension PET layer, chemical coating layer sequentially from bottom to top from its upper surface and UV layer. The adhesive layer includes a composite adhesive layer bonded to the prepainted paint layer, and a back adhesive layer bonded to the composite adhesive layer; in this embodiment, the color coating layer is selected from the aluminum plating layer, and the aluminum plating process is used to directly coat the surface of the high-stretch PET layer. Made by vapor deposition. The high elongation PET layer had a breaking elongation of 90% and a thickness of 20 μm.

[0037] The above composite film color plate is made according to the following method:

[0038] S1. Pretreatment of the steel plate layer: the steel plate layer is selected as a hot-dip galvanized sheet with a thickness o...

Abstract

The invention relates to a composite film color coated sheet and a preparation method thereof. The composite film color coated sheet comprises a steel sheet layer. A chemical treatment layer, a gum layer, a color coated layer and a high-extensibility PET layer are sequentially distributed on the upper surface of the steel sheet layer from bottom to top. The composite film color coated sheet prepared according to the preparation method has the characteristics of relatively high tensile strength, high extensibility, stable processing and low possibility of indentations.

Description

technical field [0001] The invention relates to the field of metal surface coating, in particular to a composite film color plate and a preparation method thereof. Background technique [0002] Metal steel plates are widely used in civil construction, automobile industry, household appliances and many other fields. Metal steel sheets are prone to corrosion or loss when exposed to the air directly, and it is usually necessary to cover the metal surface with a protective film to expand the use of metal materials. [0003] In order to make the protective film on the surface of the metal steel plate adhere closely to the metal steel plate, PVC, PET or a composite material of PVC and PET is usually selected as the flexible substrate for the protective film. For example, the Chinese patent with the application date of August 16, 2004 and the application number of 200420078787.5 discloses a PET aluminum foil PVC composite steel plate. The surface of the composite steel plate is pr...
