Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a dry plated product in which plated parts are provided with different colors.

Prior Art Conventional dry plating products, as shown in FIG. 8, include a base coat layer 32 provided on the surface of a base material 31 such as resin or metal, and dry plating (vacuum deposition, sputtering, ion bubbling) applied to the entire surface of the base coat layer 32. After applying a uniform coating to the metal plating layer 33 (rating, etc.), the top surface]-
A paint layer 34 was provided, a tape was pasted on the part where a metallic luster was to be left, and the other parts were masked and painted in a predetermined color tone to form a paint layer 35, and the tape was peeled off after R.

The product has a distinct metallic luster and paint part.
However, the color tone is not excellent, and the above-mentioned masking coating requires applying and removing tape for each product, which is a very troublesome process and has low work efficiency.
Manufacturing costs were also high.

Purpose The purpose of the present invention is to eliminate the above-mentioned defects, to provide a metal plating layer with a metallic luster part and a part where the color of the product base material side can be seen through, resulting in excellent color tone, simplifying the manufacturing process and improving work efficiency. The object of the present invention is to provide a dry plating product that can improve the quality of the product and reduce manufacturing costs.

Structure of the Invention In order to achieve the above-mentioned object, the present invention provides a dry plated product in which a dry metal plating layer is applied to the surface of a product base material. A configuration was adopted in which any layer thickness within the range of thick layers that cannot be seen through is selectively set and numbered so that each layer thickness is continuous.

EXAMPLE An example embodying the present invention will be described below with reference to FIGS. 1 to 3.

1 indicates a sputtering device. Reference numeral 2 denotes a cathode as a flat plate target, and at least its surface portion is formed of a metal material 3 to be deposited on the base coat layer 12 of the resin base material 5 by sputtering. As No. 3, Hastelloy alloy is used. 4 is a ring-shaped anode, and a DC voltage of 50 to iooov is applied between it and the cathode 2.

Reference numeral 5 denotes a resin base material set in the sample holder 11. For example, by spray coating a two-component urethane paint colored blue, approximately 10 g/m" of the same paint is applied per unit area, and the paint is heated at 80°C. By keeping the paint in warm air for 2 hours to cure the paint, a transparent base coat 1 layer 12 with a thickness of about 10 μm is formed. A punching plate having a large number of through holes 6a, 6b,
As shown in Fig. 2, the diameter of the through hole 6a in the left half A is
The diameter of the hole 6b is made larger than that of the hole 6b, and the perforation ratio of the left and right sides is changed.

A vacuum pump 7 is connected to the sputtering device @1 via a valve 8, and is used to reduce the pressure inside the device 1. Reference numeral 9 denotes a gas cylinder connected to the sputtering apparatus 1 via a valve 10, which contains argon gas (
Filled with Ar).

The resin base material 5 is sputtered by the sputtering apparatus 1 as described above.
In order to perform sputtering on the surface of the pace coat layer 12 to obtain a dry plated resin product, first, the inside of the sputtering apparatus 1 is depressurized by the vacuum pump 7.

Next, argon gas is fed into the apparatus 1 from the cylinder 9, and some argon gas is gradually exhausted by the vacuum pump 7, thereby maintaining the inside of the apparatus 1 in a low-pressure argon gas atmosphere.

Next, when a high DC voltage is applied between the two electrodes 2.4, a glow discharge occurs, and due to the energy of standing, argon molecules dissociate to generate argon ions, which are accelerated toward the cathode 2 side and are made of Hastelloy alloy. The alloy collides with the metal material 3, and as a result, the same alloy becomes fine particles and scatters in the sputtering device 1, and is deposited on the opposite surface of the resin base material 5.
wear it.

In this way, the dry metal plating layer 13 is formed on the surface of the resin base material 5, but the layer thickness in the portion not covered by the punching plate 6 is thicker than the layer thickness in the portion covered by the punching plate 6. Also, the layer thickness of the portion covered by the plate 6 is thicker in the portion corresponding to the left half A having a high porosity than in the right half B.

The resin product sputtered in the above process becomes a stepwise metal plating layer 13, forming banding brakes 1 and 6.
The layer thickness in the areas not covered by
00 people (Ongeström), and in the covered area, the layer thickness is less than the hiding film thickness of 300 to 10 people, so the metallic luster gradually changes and the blue color of the colored base coat layer 12 can be seen through. This is a dry plated resin product.

After forming the dry metal plating layer 13, urethane 2 is applied on the same layer 13.
Spray coating with liquid type paint to 20o/+? fJ
After it has arrived, it is kept in the warm air at 70℃ for 1 hour to make it about 20μ
m-thick transparent top layers 1 to 14 are formed.

In this example, the base coat layer 12 is colored blue, and the left and right sides have different porosity ratios. The color of the sea urchin is set continuously from a thick layer that cannot be seen through to a thin layer that allows the color to be seen through.
Therefore, the product can have an excellent color tone that changes stepwise from metallic luster to blue with a metallic feel and further to almost blue.

The base coat layer 12 can smooth the surface of the resin base material 5 if it is rough, and can also impart any color to the resin base material 5. In addition, since both the adhesion of the base coat layer 12 to the resin base material 5 and the adhesion of the metal plating layer 13 to the base coat layer 12 are very strong, the adhesion and peeling resistance of the metal plating layer 13 are improved. Durability can be increased.

In addition, the metal plating layers 1 to 14 are very thin metal plating layers 1.
3 from peeling and deterioration, preventing fading and discoloration, and improving wear resistance and weather resistance.

Furthermore, dry plating with different colors can be achieved in a single sputtering process, which simplifies the manufacturing process and reduces manufacturing costs compared to conventional masking coating where tape is applied and then peeled off. I can do it.

Next, another embodiment of the present invention will be described with reference to FIGS. 4 and 5.

1, an oblique surface S2 that is difficult to adhere to, and a parallel surface S3, so the metal plating layer 13 naturally has a different thickness. The layer thickness gradually changes from 3006 to 10 at the lower end of surface S3, resulting in an excellent color tone that gradually changes from -C metallic luster to the color of the blue base coat layer 12. Further, since there is no punching plate 1-6 in the radiator grille outer peripheral portion 15b, only the metallic luster of the thick plating layer is present.
