Problems solved by technology

Through the surface treatment of buttons, light guide columns and other products by NCVM, it is required that the font part and the part of the light guide surface can be unshielded, so that the light can pass through smoothly and maintain a high pass rate. The part other than the font or the light guide surface does not require light to pass through, but At the same time, it is necessary to ensure that the plastic surface has a high metal texture without affecting the propagation of electromagnetic wave signals and keep the signal unblocked. However, NCVM is greatly limited in the shading effect, and it is difficult to achieve a complete shading effect.

Embodiment Construction

[0017] see figure 1 , the coating member 10 of the present invention comprises a transparent substrate 11, a primer layer 13 is formed on the transparent substrate 11, a metal layer 15 is formed on the primer layer 13, and the metal layer 15 is formed by vacuum evaporation , and finally, a topcoat layer 17 is formed on the metal layer 15 .

[0018] The transparent substrate 11 is made of a transparent material, such as a transparent plastic material, and the plastic material selected in this preferred embodiment is transparent polycarbonate (Polycarbonate, PC) or polymethyl methacrylate (Polymethyl Methacrylate, PMMA).

[0019] The main component of the primer layer 13 is acrylic acid, and the thickness of the primer layer 13 is about 10-20 μm. The primer layer 13 is added with white color paste, and its mass percentage is 35%-40%. The main component of the white color paste is titanium dioxide pigment, and its function is to cooperate with the coating layer to shield the l...

Abstract

The invention provides a film-coating member, comprising a transparent substrate. A basecoat layer, a metal layer and a topcoat layer are formed on the transparent substrate successively, wherein the basecoat layer is acrylic acid added with 35-40% by mass of white color paste or 2-4% by mass of a black color paste; the metal layer is formed by an NCVM method; and the topcoat layer is a printing ink. The invention also provides a manufacturing method of the film-coating member. The film-coating member has a light-shielding the effect and good appearance.

Description

technical field [0001] The invention relates to a coating piece and a manufacturing method of the coating piece, in particular to a coating piece with good light-shielding effect and good appearance and a manufacturing method thereof. Background technique [0002] The main feature of NCVM is that it combines the characteristics of traditional vacuum coating technology, adopts new coating technology and new materials, and makes a metal appearance effect different from ordinary vacuum plating, which can beautify the surface of the workpiece. Through the surface treatment of buttons, light guide columns and other products by NCVM, it is required that the font part and the part of the light guide surface can be unshielded, so that the light can pass through smoothly and maintain a high pass rate. The part other than the font or the light guide surface does not require light to pass through, but At the same time, it is necessary to ensure that the plastic surface has a high metal...
