CONSTITUTION:A coating film 17 is formed by forming a metallic color base coat 11 on the surface of a base material 10, forming a clear coat 12 thereon, forming a thin metal film layer 14 with light permeability by means of a vaccum plating and furthermore, forming a pearl coat 15 and a clear coat 16.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating method for giving a pearly feel and a metallic feel to the surface of a substrate such as plastic.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional pearl coating method applied to plastic interior and exterior parts of a vehicle is a coating material such as acrylic urethane resin on a base material 1 such as ABS resin. A color base coat 2 is formed, and a pearl coat 3 and a clear coat 4 are sequentially formed on the color base coat 2 to form a coating film 5. Pearl coat 3
Is formed by mixing mica covering the silica particles with titanium oxide into a transparent acrylic melamine resin paint or the like, and the clear coat 4 is formed from a similar acrylic melamine resin paint or the like, and the coating film 5 The incident light is reflected by the pearl coat 3 according to the angle, or
By transmitting the light, a pearly feeling can be generated in the coating film 5, but the coating film 5 does not have a metallic glitter, and the depth of the color tone is insufficient.

Further, in the bright method described in Japanese Patent Laid-Open No. 3-267173, a base coat layer which is a coating layer, a very thin metal coating layer, and an ultra-low viscosity layer are formed on the surface of a substrate in order from the bottom. Although the top coat lower layer and the top coat upper layer are applied, color brilliance can be realized,
Since a so-called pearly feeling cannot be generated, it is difficult to give the coating film a deep color tone.

[0004]

DISCLOSURE OF THE INVENTION The present invention is intended to give a high-grade feeling by giving a deep and unique brilliant color tone including a pearly feeling and a metallic feeling to a coating film.

[0005]

In order to achieve this object, a coating method according to the present invention comprises a base coat formed on the surface of a base material, and a thin metal film having a light-transmitting property above the base coat by vacuum plating. A layer is formed, and a pearl coat is formed on the metal coating layer to form a coating film.

In the coating method according to the present invention, a metallic base coat is formed on the surface of a substrate, and a thin metal film layer having a light-transmitting property is formed above the metallic base coat by vacuum plating. A pearl coat is formed above the to form a coating film.

[0007]

In the above coating film, the metal coating layer formed above the base coat is thin and can transmit light. Therefore, the pearl coat above the metal coating layer is combined with the metal coating layer, or The film layer and the metallic base coat thereunder simultaneously exhibit a pearly feeling and a metallic feeling, and since the pearly feeling is further enhanced by the synchronization of the metallic feeling, a deep and distinctive luster color tone is produced.

[0008]

EXAMPLES Examples of the present invention will be specifically described below. In FIG. 1, on the surface of an ABS resin base material 10 such as a front grill and a garnish, which are parts for vehicles,
By sequentially coating and baking ordinary metallic color base paint containing aluminum pigment mixed with color pigment and clear paint such as acrylic melamine resin,
Metallic color base coat 11 and clear coat 12
Are formed, and then the metallic color base coat 1
The surface part that does not require pearl coating in 1 is paper,
After being covered with a masking material 13 such as a polyester resin film, it is made of a corrosion-resistant metal such as Cr or CrNi alloy by vacuum plating such as vacuum deposition or sputtering 10
A coating layer 14 having a thickness of 0 to 200 microns is formed.

Since the metal coating layer 14 is as thin as 100 to 200 microns, fine metal particles adhere to the clear coat 12 in spots, and extremely many minute gaps are formed between them. The metal film layer 14 has a light-transmitting property, and the surface layer portion of the clear coat 12 enters into the minute gaps to improve the adhesion between the two.

Then, as shown in FIG. 2, a pearl paint in which mica is mixed in a clear paint such as an acrylic melamine resin and a clear paint are sequentially applied on the metal film layer 14 and baked, whereby the pearl coat 15 and The clear coat 16 is formed, and then the masking material 13 is formed.
After the removal, the desired coating film 17 is formed on the base material 10, and the lower layer portion of the pearl coat 15 enters into the minute gaps of the metal coating layer 14 to improve the adhesion between them. .

At this time, the coating film 17 reflects the metallic feeling of the metallic color base coat 11 and the metallic film layer 14 on the pearly feeling of the pearl coat 15 due to the translucency of the metallic film layer 14, and the pearly feeling is obtained. As a result of being further enhanced by the metallic feeling, a color tone having a metallic glittering and unique glittering feeling is obtained, and therefore a coating film having a deep and high-grade color tone can be obtained.

Further, since the metallic base coat 11 itself is colored and a color base coat is not required separately, there is an advantage that the coating process can be simplified. Furthermore, since the metal coating layer 14 is sandwiched between the clear coat 12 and the pearl coat 15 and the facing portions of the two coatings 12 and 15 enter into the minute gaps of the metal coating layer 14, the respective adhesiveness is improved, The coating film 17 is easily prevented from peeling at the portion of the metal coating layer 14, and the strength of the coating film 17 can be maintained.

When the pearl paint is applied on the metal film layer 14, the masking material 13 is removed, and then the clear paint is applied, so that the metal film layer 14 and the pearl exposed by the removal of the masking material 13 are removed. Coat 15
The side cross section of can also be covered with the clear coat 16, and the surface protection of the coating film 17 can be ensured. Further, even if the metallic base coat of the above-mentioned embodiment is replaced by a normal color base coat, the effect similar to that of the above-mentioned embodiment can be obtained due to the presence of the metal film layer and the pearl coat above it.

[0014]

EFFECTS OF THE INVENTION In the coating film formed by the coating method of the present invention, the pearl coating above the metal coating layer is combined with the metal coating layer, or the metal coating layer and the metallic base coating below the pearl coating give a pearly feeling and At the same time, a metallic feeling appears, a deep and unique color tone of a glittering feeling is given, a high-grade feeling can be given, and the adhesive strength of the coating film is relatively large even if the metal film layer is present.
