Embodiment Construction

[0021] The specific implementation of the present invention will be further described below in conjunction with the examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0022] The technical scheme of concrete implementation of the present invention is:

[0023] A coloring process for a mobile phone shell, first forming an electrophoretic primer on the surface of the mobile phone shell, and then forming a UV varnish topcoat on the surface of the electrophoretic primer;

[0024] The host resin of the UV varnish topcoat comprises the following components:

[0025] 6 functional group polyurethane resin,

[0026] 2-functional acrylate oligomer,

[0027] Phosphates,

[0028] 4 functional group polyurethane resin.

[0029] Preferably, in the host resin:

[0030] The mass percent composition of 6 functional group polyurethane resins is 20%,

Abstract

The invention provides a coloring process for a mobile phone shell, comprising the steps as follows: firstly forming an electrophoretic primer on the surface of a mobile phone shell, and then forminga UV varnish topcoat on the surface of the electrophoretic primer. According to the invention, the electrophoretic primer matches the UV varnish topcoat. The overall film thickness of the electrophoretic primer is uniform, the color is stable, and the metallic feeling and texture of the film can also be increased. The UV varnish topcoat can provide gloss and protective effect. The UV varnish topcoat has excellent adhesion on the electrophoretic primer and is resistant to boiling.

Description

technical field [0001] The invention relates to a coloring process of a mobile phone shell. Background technique [0002] At present, the coloring process of mobile phone casings in the industry mostly uses thermoplastic primer + UV varnish. The color is basically provided by the primer. Due to the spraying method, it is difficult to control the film thickness of some bright colors when spraying, which will lead to overall The color is uneven, and the overall appearance is metallic and the texture is not strong. Contents of the invention [0003] The purpose of the present invention is to provide a coloring process for mobile phone casings, which adopts the matching method of electrophoretic primer and UV varnish topcoat; the overall film thickness of the electrophoretic primer is uniform, the color is stable, and the metal of the paint film can also be increased. Feel and texture; UV varnish topcoat can provide gloss and protection; and UV varnish topcoat has excellent a...
