Problems solved by technology

The non-metallic composite materials used in electronic products are generally composed of carbon fiber or glass fiber and resin. Due to the high strength and hard surface of this material, it is difficult to form patterns on its surface. Only one surface treatment process can achieve the desired effect, which leads to complex surface treatment process and high cost of composite materials, which is not conducive to the increase of its market share, and hinders its application and development to a certain extent.

Embodiment

[0029] Embodiment: A method for making a composite material appearance part with a pattern, stacking several layers of plastic fiber cloth 11 soaked in resin in advance to form a composite material stack 1, the composite material stack has two opposite two surfaces, at least one of the two surfaces is covered with a decorative molding film 2, and the decorative molding film is successively composed of a back glue layer 21, an ink layer 22, a product surface UV material layer 23, a release layer 24 and a PET layer 25. and the decorative molding film 2 covers the composite material stack 1 at the adhesive layer 21, and then pressurizes and heats the mold so that the composite material stack is solidified and molded together with the decorative molding film After the mold is opened, the decorative molding film is torn off at the release layer 24 to obtain the patterned composite material appearance part A of the present invention. The patterned composite material appearance part c...

Abstract

The invention discloses a composite appearance product with patterns and a production method thereof, which are manly characterized in that a composite stack and a decorative formed film are placed in a mould simultaneously, the decorative formed film is composed of a back glue layer, an ink layer, a production surface UV (ultraviolet) material layer, a release layer and a PET(polyethylene glycol terephthalate) layer, the decorative formed film is integrally joined with composite while the composite is formed, and accordingly the surface UV material layer, the ink layer and the back glue layer of the product with the decorative formed film are joined to the composite. The composite appearance product with patterns composed of a composite part, the back glue layer, the ink layer and the product surface UV material layer is produced by tearing the decorative formed film after mould opening, so that surface treatment process for the composite appearance product is simplified, and the appearance effect that the traditional composite cannot reach is realized.

Description

technical field [0001] The invention belongs to the field of manufacturing and surface treatment of appearance parts of electronic products, and in particular relates to a patterned composite material appearance part and a manufacturing method thereof. Background technique [0002] IMR (In-Mold Decoration Molding) This process is to print the pattern on the film, and extrude the film and the mold cavity through the film feeding machine. After extrusion, the patterned ink layer is separated from the film, and the ink layer remains There is no transparent protective film on the surface of the final product, and the film is only a carrier in the production process. The traditional IMR is a bright surface IMR, and the decorative film used is sequentially composed of an adhesive layer, an ink layer, a UV material layer on the product surface, a release layer and a PET layer. The surface of the appearance piece has a smooth pattern. The non-metallic composite materials used in e...
