Abstract

PROBLEM TO BE SOLVED: To provide a new coating structure with durability different from conventional structures that provides a sense of high-class products with enhanced texture such as a metal having brightness even if a device body case of a portable phone or the like is a synthetic resin molded article. SOLUTION: A colored paint layer 20 that is mirror-surface finished to have luster is formed on the surface of a device body 10 made of a synthetic resin molded article with respect to a synthetic-resin-made device body case 10a as a base color, and a transparent or translucent resin film 30 blended with particles of a bright metal such as aluminum or nickel is integrally formed on the base color paint layer 20.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body of a device such as a portable telephone, a calculator, a small radio or a camera, and more particularly to a structure for coating a body case of the portable telephone.

[0002]

2. Description of the Related Art A so-called portable telephone in which a handset and an operation mechanism are integrated is lightweight, small in size, and often carried with the user. For this reason, since the main body case is likely to be sold in large quantities in addition to its strength and durability, its constituent members are required to be made of a material having high workability so as to be suitable for mass production. For these reasons, in the conventional mobile phone, a hard synthetic resin material is used as a constituent member of the main body case and the front panel, and is painted to hide the background.

[0003]

According to the above-mentioned conventional portable telephone, the main body case and the front panel have the appearance of the material of the constituent members as they are, so that the ground of the synthetic resin material has a cheap texture. The painting to give and hide is only to give a new color by concealing the base color by applying or spraying colored paint on the surface of the body. Even gloss,
There is a problem in that the metal is lacking in appearance or high quality as compared with a high-grade metal in terms of glitter and the like.

The present invention has been made in view of the above-mentioned conventional problems. Even if the main body case of a cellular phone or the like is a molded product made of a synthetic resin, it has a high quality feeling such as a high-luminance metal. It is an object of the present invention to provide a new paint structure that is durable and has never existed before.

[0005]

In order to solve the above-mentioned problems, a coating structure of a device body such as a portable telephone according to the present invention has a mirror surface so that the surface of the device body 10 made of a synthetic resin molded article can be glossy. A finished or colored paint layer 20 is formed as a base color, and a transparent or translucent resin film 30 mixed with glittering metal particles 31 such as aluminum or nickel on the base color paint layer 20. Are formed so as to be integrally attached. Also,
A transparent or translucent resin film 30 mixed with particles 31 of a brilliant metal such as aluminum or nickel is integrally formed on the surface of the device main body 10 made of a synthetic resin molded product having a mirror finish so as to be glossy and having a color. It can also be formed to be attached.

According to the above-described coating structure, the main body case and the front panel of a cellular phone or the like are formed with a thin resin film containing aluminum particles formed on a coating layer as a base color. Although it is a molded article of a synthetic resin, the shine of the aluminum particles is made clearer by seeing through the color and gloss of the metal particles, and it gives an unprecedented brilliant metallic metallic feeling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIGS. 1A and 1B show an embodiment of the present invention applied to a portable telephone, and FIGS. In FIG. 1, a mobile phone main body 10 includes a main body case 10a and a front panel 10b fitted and fixed to the main body case. An operation mechanism 5 including a transmission / reception mouthpiece 2.3 and a display unit 4 is provided on the front panel 10b. The main body case 10a and the front panel 10b are made of an ABS hard resin material or another hard synthetic resin material.

The main body 10 of such a synthetic resin material has no gloss on the surface and is rough and rough, so that a base treatment is first performed before painting. After this undercoating treatment, as shown in FIG. 2, a paint layer having a base color and a mirror-finished paint such as black, dark brown, navy blue or the like is sprayed by a spray gun to give a gloss and has a color.
0 is uniformly formed on the surface. Next, an extremely thin resin film 30 is formed on the base color coating layer 20 by spraying an epoxy-based transparent resin coating mixed with aluminum particles 31 under high pressure by an air spray gun. Instead of aluminum particles, particles or fine particles of a bright metal such as nickel or gold or silver can also be used. The particles of the brilliant metal such as aluminum are resin-coated with a resin paint, and are formed in a thin film on the base color paint layer 20.

As shown in FIG. 3, when the surface of the main body 10 is itself glossy, mirror-finished, and has a dark color such as black, dark brown, or the like, the surface of the main body 10 Is used as a base color, and a resin paint mixed with glittering metal particles is directly sprayed thereon to form a resin film 30.
Can also be formed.

As a transparent epoxy resin coating, a good result was obtained by diluting acetone and alcohol at a ratio of 40 to 50% by weight, and further adding 5% by weight of toluene to a commercially available product. After that, a top coat may be applied to the resin film 30 for protection if necessary.

According to the above embodiment, the main body case and the front panel are different in that the base color as the base is concealed by the conventional paint, and the gloss and color of the transparent resin are applied to the aluminum particles through the transparent resin. To reflect, furthermore, the aluminum particles are further shined by the base color and embodied on the surface,
Even if it is a main body of a synthetic resin molded product, it is possible to obtain a beautifully shining high-quality metallic feeling unprecedented.

In the above embodiment, the particles of the glittering metal mixed into the resin paint applied on the base color are:
By adjusting the amount, or by mixing two or more kinds of different metal particles such as aluminum and brass, it is easily possible to give a slightly changed metallic feeling.

[0014]

As described above, according to the present invention, even in the case of a main body such as a cellular phone made of synthetic resin, a high quality metallic feeling can be easily and reliably obtained, so that the decorativeness is improved. The texture is improved and the product value is improved.
