Composite face plate with wood-grained structure and for refrigerator and manufacturing method of composite face plate

Abstract

The invention discloses a composite face plate with a wood-grained structure and for a refrigerator and a manufacturing method of the composite face plate, and relates to the field of composite face plates. The composite face plate comprises a galvanizing base layer, chromium-free passivation layers are composited on both sides of the galvanizing base layer, a film pasting base coat layer, a filmpasting finishing coat layer, a PVC layer, a 3D wood pattern layer, an adhesive layer, and a PE layer are composited on the surface of one chromium-free passivation layer, and an epoxy back paint layer is composited on the surface of the other chromium-free passivation layer. The composite face plate uses a colloidal surface to print the pattern texture on a PVC base film to form the 3D wood pattern layer through a pattern edgy roller made of digital printing, the colloidal pattern edgy roller do not easily concentrate heat, and the problems that an existing steel pattern edgy roller concentrates the heat, the pattern fit degree is low, the surface pattern is likely to be softened by high temperature, the pattern effect is likely to miss, an existing refrigerator door panel is in a singlecolor, the existing refrigerator door panel cannot integrate with the home decoration background according to the selection of a user, and beauty and coordination cannot be achieved are solved.

Description

technical field [0001] The invention belongs to the field of composite panels, in particular to a composite panel for refrigerators with a wood grain structure and a manufacturing method thereof. Background technique [0002] With the increasing rise of home-integrated decoration style, there are more and more customization requirements for household appliances, and the market demand for color customization of refrigerators is particularly strong. If the color of the refrigerator panel can be changed according to the color of the home, it will be more able to drive the overall beauty of the home. [0003] In order to change the color of the refrigerator in accordance with the home environment, the existing pattern image with 3D effect is realized by the pattern overprinting technology. In the traditional process, the pattern rollers required for overprinting are mainly engraved by hand, and there are errors in manual engraving. In the actual production process, the differen...

Problems solved by technology

[0004] The object of the present invention is to provide a composite panel for a refrigerator with a wood grain structure and a manufacturing method thereof, by sequentially compounding a chromium-free passivation layer, a film primer layer, a film topcoat layer, a PVC layer, 3D wood grain layer, adhesive layer, PE layer, and the other side is compounded with chrome-free passivation layer and epoxy back paint layer. The 3D wood grain layer is customized according to the overall color and decoration of the home, and a colloidal surface is used to pass through The patterned roller produced by digital printing overprints the texture on the PVC base film to form a 3D wood grain layer. The colloidal patterned roller is not easy to accumulate heat, which solves the problem of heat accumulation of the existing steel patterned roller. The fineness of pattern bite is low and the surface The pattern is easily softened by high temperature, and the effect of the pattern is easily lost. The existing refrigerator door panel is a single color, which cannot be integrated with the home decoration background according to the user's choice, and the problem of unsightly coordination
