Problems solved by technology

This process has the following limitations: 1) It can only be used for flat products, and it is difficult to process three-dimensional products; 2) For structures with edge chamfers on the product surface, the processing is more complicated and the cost is high
This process has the following limitations: due to the poor combination of substances with different properties in the UV layer, NCVM layer and ink layer, the edge of the product of this process is easy to delaminate after testing, which affects the appearance of the product, and the processing cost is relatively high
This process has the following limitations. It cannot achieve a more delicate three-dimensional effect. It cannot process products with a high side and a small slope. The processing cost is high and the process is unstable.

Abstract

The invention discloses a surface treatment process for a plastic product, which comprises the following steps of: 1) coating ultraviolet (UV) finish paint on the surface of a base material, embossing the surface of the UV finish paint, putting the base material into a UV furnace and curing to make a UV embossed layer formed on the surface of the base material; 2) performing non conductive vacuum metallization (NCVM) on the UV embossed layer to form an NCVM layer; 3) printing an ink layer on the NCVM layer; 4) punching the printed base material to form a sheet; and 5) putting the sheet obtained through punching into a corresponding injection mold for injection molding to obtain a finished product. The treatment process is easy to operate and low in implementation cost, and the processed product is high in third dimension, surface gloss and hardness, and is widely applied to various product structures.

Description

technical field [0001] The invention relates to a surface treatment process of plastic products, in particular to a process for treating the surface of plastic products to have high stereoscopic vision, high gloss and high hardness. Background technique [0002] With the advancement of technology, consumer electronic products such as mobile phones and tablet computers are also developing rapidly. When consumers buy such products, the aesthetics of the surface has become an important indicator in the eyes of consumers. In order to make the plastic surface have a strong three-dimensional effect, there are currently the following treatment methods: [0003] 1. Print three-dimensional lines or UV embossing on the PC board, and then electroplating or coating a high-gloss paint layer to achieve three-dimensional high-gloss vision on the product surface. This process has the following limitations: 1) It can only be used for flat products, and it is difficult to process three-dim...
