Problems solved by technology

However, when spraying is used to achieve gradient colors, the gradient effect is greatly affected by spraying equipment and paint properties, and there are too many fluctuation factors (involving production line speed, spraying air pressure, fog width, gun distance, baking temperature, paint film thickness, paint viscosity) , coating uniformity, etc.), cannot stably achieve the gradient effect and fineness within the required range, and is prone to problems such as pitting, blooming, and unstable gradient areas. Due to the unstable gradient color achieved by spraying, it leads to product failure. Low yield rate, poor production capacity and unstable batch product consistency

Abstract

The invention discloses a housing and a preparation method thereof, an electronic equipment, wherein the method comprises the following steps: forming a transparent ink layer on a first surface of a substrate; Forming a gradient color by dipping on the transparent ink layer; A dye protective layer is formed on the surface of the transparent ink layer after dyeing to seal the gradient color formedby dipping. The invention realizes stable gradient color.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a housing, a preparation method thereof, and electronic equipment. Background technique [0002] The description of the background technology of the present invention belongs to the relevant technology related to the present invention, and is only used to illustrate and facilitate the understanding of the content of the present invention. prior art on the filing date. [0003] The shells (such as back covers, etc.) of electronic devices such as mobile phones and tablet computers generally use composite plates composed of multiple sheets. Sometimes it is necessary to achieve a gradient color effect on the composite board. The general implementation method is to superimpose multi-layer spraying, and the gradient of color depth will appear according to the number of sprayed layers. However, when spraying is used to achieve gradient colors, the gradient effect is great...
