A refrigerator door trim strip and its surface treatment method

Abstract

The invention discloses a refrigerator door trim and a surface treatment method thereof, and relates to the technical field of door trim surface treatment. The present invention comprises a door trim body; a rectangular groove is provided on the door trim body; a 3D special-shaped curved surface is provided at the connection between the rectangular groove and a surface of the door trim body; a number of ventilation holes are provided on the door trim body The surface of the door trim body is sealed with a decorative film; the decorative film includes a PET base material, a UV layer, an ink layer, and an adhesive layer sequentially from the inside to the outside. The present invention moves the decorative film to the top of the door trim body by opening air holes on the surface of the door trim body, and seals the surroundings of the decorative film with the door trim body; then vacuumizes the sealed space to make the decorative film stick Coated on the surface of the decorative strip body, it has high hardness and high color diversity; it is environmentally friendly and efficient; it solves the problem that the IMD process cannot be applied to curved surfaces with large R angles, especially 3D special-shaped surfaces.

Description

technical field [0001] The invention belongs to the technical field of door trim strip surface treatment, in particular to a refrigerator door trim strip and a surface treatment method thereof. Background technique [0002] For refrigerator door trim, there are three commonly used surface treatment methods: [0003] Type 1: Plastic particles are used for direct injection molding. This method has mature technology, high efficiency, and low product price, but its significant disadvantages are: First, the surface hardness of the product is low: it cannot reach 2H. When it is produced along the line, it is prone to knocking, Quality defects such as bumps and scratches are difficult to repair; second, the color of the product is single: for example, only single colors such as gray and black can be realized, and effects such as gradient colors, brushed wire, and imitation wood grain cannot be realized, and the appearance characteristics of the product cannot be highlighted, which ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a refrigerator door trim and its surface treatment method. By opening air holes on the surface of the door trim body, the decorative film is moved to the top of the door trim body, and the surrounding area of ​​the decorative film is connected to the door trim. The strip body is sealed; then the sealed space is evacuated so that the decorative film is attached to the surface of the decorative strip body, which solves the problem of low hardness and single color of the refrigerator door trim surface during injection molding; and the IMD process cannot be applied to the R angle. Problems with large curved surfaces, especially 3D shaped surfaces
