An aluminum foil-coated board for home appliances with wire drawing effect

Abstract

The invention discloses an aluminum foil laminated board for a home appliance with a drawing effect. The aluminum foil laminated board comprises a galvanized passivated base material, wherein a chemical coating and graphene oxide-waterborne organic silicon modified acrylic resin coating are overlapped in turn on the front and back of the galvanized passivated base material; a polyurethane adhesive layer, a laminating layer and a protective coating are overlapped in turn on the graphene oxide-waterborne organic silicon modified acrylic resin coating on the front; the chemical coating is a chromate chemical pretreatment liquid film; the laminating layer is an aluminum foil drawing PET composite film; the front of the aluminum foil has a drawing texture pattern, and a PET film is laminated and fitted on the drawing texture pattern; the back of the aluminum foil covers the graphene oxide-waterborne organic silicon modified acrylic resin coating through a polyurethane hot melt glue. The aluminum foil laminated board disclosed by the invention has good coating insulation, heat dispersion, antistatic property and drawing texture beauty, excellent comprehensive physical and mechanical properties and good protectiveness.

Description

technical field [0001] The invention relates to a composite film for household electrical appliances, in particular to an aluminum foil-coated panel for household electrical appliances with a drawing effect, and belongs to the field of composite materials. Background technique [0002] In order to improve the competitiveness of product appearance, panels with brushed metal effects are widely used in home appliances. At present, there are two kinds of wire drawing panels commonly used in the market: one is to directly use stainless steel, aluminum plate, plastic plate and other substrates through the wire drawing die to turn a straight line texture; the other is to print the wire drawing pattern on the PET film, and then combine with Composite base material. The former has a strong metallic feel, but requires high mold requirements, and each texture corresponds to a set of molds, which is not easy to change; and the brushed texture is inconsistent with the weakening of the s...

AI Technical Summary

Problems solved by technology

The former has a strong metallic feel, but requires high mold requirements, and each texture corresponds to a set of molds, which is not easy to change; and the brushed texture is inconsistent with the weakening of the sand belt, and the latter is closer to plastic in appearance, and is usually only used in low-end products. The appearance cannot meet the needs of high-end products

[0003] In addition, in order to prevent the panel of home appliances from being scratched and damaged due to bumps and scratches, the commonly used solution is to cover the outer surface with a PE protective film, but ordinary PE protective films have many disadvantages: such as insufficient hardness; wear resistance Poor; the adhesion between the product to be protected is not firm, and it is easy to fall off and the wings at both ends are lifted during use
