Embodiment 1～5

[0048] According to the manufacturing method that the application provides the plastic shell, the plastic shell is obtained, and its cross-sectional structure is as follows: figure 1 shown. The colored primer layer 11 and the first transparent topcoat layer 12 are successively sprayed on the back of the transparent plastic housing 1, and the transparent primer layer 21, the metal layer 22, the transparent middle paint layer 23 and the transparent primer layer 23 are successively sprayed on the front of the plastic housing 1. Second clear topcoat layer 24 .

[0049] The back of the transparent plastic shell 1 has a second texture pattern, the thickness of the transparent plastic shell 1 is 0.7±0.05mm, and the light transmittance is ≥70%.

[0050] The colored primer layer 11 adopts a baking-type colored primer with a thickness of 5-8 μm, and the color of the colored primer determines the color of the plastic shell.

[0051] The first transparent topcoat layer 12 is a transpare...

Abstract

The invention relates the technical field of plastic surface treatment, in particular to a manufacturing method for a plastic shell part and the plastic shell part obtained through the method. The method at least includes the following steps that firstly, a transparent plastic shell is obtained through injection molding; secondly, the first surface of the transparent plastic shell is sequentially coated with colored primer and transparent finishing coat; and thirdly, a metal layer is electroplated on the second surface, opposite to the first surface, of the transparent plastic shell. The colored primer and the transparent finishing coat are matched with the electroplated metal layer, a more diversified and adjustable three-dimensional metal texture effect and touch hand feeling can be achieved, and the plastic shell is endowed with rich color choices.

Description

technical field [0001] The present application relates to the technical field of plastic surface treatment, in particular, to a manufacturing method of a plastic shell and a plastic shell obtained by the method. Background technique [0002] Plastic material, referred to as plastic, is a kind of polymer material, which has the advantages of easy molding and quality, and is widely used in digital, home appliances, automobiles and other products. With the rapid development of electronic products, the use of portable electronic devices such as mobile phones, MP3 players, personal digital assistants, and notebook computers has become very common. In order to have better appearance and special feel, more and more portable electronic devices usually use vacuum plating process on the appearance parts to have a metallic appearance effect, or form some decorative patterns or lines on them. [0003] There are many decorative treatment processes on the plastic surface. Currently, the ...
