Outer shell and preparation method thereof

Abstract

The invention discloses an outer shell, which is characterized by comprising a shell body, a first polymer, a second polymer and a gold foil layer, wherein the shell body comprises a first surface and a second surface arranged opposite to the first surface; the first polymer is located on the first surface of the shell body, and one side, away from the shell body, of the first polymer is provided with a graphic structure or a textured structure, thereby forming a first structural layer; the second polymer is formed on the side, away from the shell body, of the first polymer; and the gold foil layer is positioned between the first polymer and the second polymer. According to the outer shell and the preparation method thereof, the surface of a product produces different texture effects, the stereo feeling and layering feeling are strong, the surface effect is rich and beautiful, the glossiness and flatness of the product surface are good, and the service life of the product is long.

Description

Technical field [0001] The invention relates to the field of shells, in particular to a shell and a preparation method thereof. Background technique [0002] For existing electronic products, the patterns and text on the shell are generally processed on the surface of the product shell by silk screen, bronzing, laser engraving and other methods. Through these methods, the pattern or text on the shell can be permanently fixed to the shell. on. Among them, bronzing is a method that uses heating and pressure to transfer patterns or text to the surface of the material to be stamped. It is a more environmentally friendly and low-cost metal layer manufacturing method because it can form a clear, Beautiful patterns or characters, making products display strong decorative effects and giving products high anti-counterfeiting performance have attracted much attention. [0003] The existing process is usually directly on the material or on the surface of the processed part after the color t...

Problems solved by technology

[0003] The existing process is usually to directly stamp on the material or the surface of the craft with color treatment to form high-gloss and different color effects on the part or the whole surface, and form a surface bronzing foil. There are still some defects in the process of hot stamping foil on the surface of the craft parts after color treatment, such as not enough wear resistance and scratch resistance, poor adhesion of hot stamping patterns or characters on the product surface, wrinkling and blistering on the surface of hot stamping products, poor layering, and smoothness Effects such as brightness, gloss and three-dimensional effect are not satisfactory
