[0003] The hardened paint film formed by traditional light-curing coatings is transparent. Although it can improve the surface properties of the substrate, it must be sprayed with primer (and color paint) to make the substrate have different colors, that is, at least two sprays are required. In order to take into account the surface performance and the use requirements of various colors

Abstract

The invention mainly relates to an appearance part and a surface treatment method thereof, and electronic equipment. The method comprises steps that the surface of a substrate is coated with a photocureable coating; illumination treatment on the photocureable coating is performed so that the photocureable coating is cured on the surface of the substrate to form a cured layer; the curing layer is heated to enable the curing layer to expand to form a crack structure; the surface of the curing layer is coated with filler, and fissures of the curing layer are filled with the filler. The method isadvantaged in that the curing process of the photocureable coating is separated from the adding process of the filler in another way, that is, the photocureable coating is firstly cured and then added, so the curing process of the photocureable coating is not influenced by the filler, the curing effect of the photocureable coating can be ensured, selectivity of the filler in the aspects of variety, concentration, particle size and the like can be improved, so the surface treatment effect of the appearance part and the application range of the photocureable coating are improved.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to appearance parts and surface treatment methods thereof, and electronic equipment. Background technique [0002] Photocurable coatings are mainly composed of oligomers, photoinitiators, reactive diluents and various additives. Generally, high-energy ultraviolet light is used as the curing energy source. The photoinitiator in the coating absorbs ultraviolet light to generate free groups or cations, triggering oligomers and reactive diluents to undergo polymerization and crosslinking reactions, thereby hardening to form a paint film. The light-cured paint film has a three-dimensional structure, has the characteristics of high hardness, good wear resistance and high transparency, and can effectively improve the surface properties of the substrate. [0003] The hardened paint film formed by traditional light-curing coatings is transparent. Although it can impro...
