Multi-layer three-dimensional texture substrate and manufacturing method thereof

Abstract

The invention discloses a multi-layer three-dimensional texture substrate and a manufacturing method thereof. The manufacturing method of the multi-layer three-dimensional texture substrate comprises the following steps: providing a substrate; performing the first hairline processing on a working surface of the substrate so as to form multiple first hairline grains on the working surface of the substrate; coating ink on the working surface according to the pre-determined pattern, and drying the ink; performing the second hairline processing at the place of not coating ink on the working surface of the substrate so as to form multiple second hairline grains on the working surface of the substrate; removing ink on the working surface; and etching the substrate to form multiple etching grains and obtain the multi-layer three-dimensional texture substrate. Through multiple times of hairline processing, the hairline grains with different thicknesses and depths can be formed, and in combination with etching treatment, the three-dimensional texture with more than three layers can be formed on the working surface of the substrate, thus the substrate can obtain a variable surface.

Description

technical field [0001] The invention relates to a method for manufacturing a substrate, in particular to a method for manufacturing a substrate that can present three or more layers of multi-layer decorative patterns on the plane of the substrate to present a variety of textures in terms of appearance. Background technique [0002] Today's electronic equipment not only emphasizes the quality and performance of internal hardware and software, but also emphasizes novelty and variety in external shapes and patterns, so as to attract consumers' favor. Therefore, in order to attract the attention of consumers, various decorative patterns and patterns are usually formed on the surface of the shell of the mobile phone, notebook computer or other electronic products, so that the surface of the shell presents different textures and marks. [0003] The existing method of forming decorative patterns on a substrate (usually an aluminum plate) as a housing includes coating ink on the sur...

Problems solved by technology

[0004] However, the existing methods for forming decorative patterns on the substrate can only form two-layer three-dimensional decorative patterns on the substrate by etching, but cannot present more layers of patterns or decorative patterns, making the appearance of the substrate too monotonous and variable. sexual insufficiency
