Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method of manufacturing a glass particulate reflective film product, and in particular, a glass particulate reflective film is formed on the surface of an article such as a bell, and the reflection on the surface is The present invention relates to a method for manufacturing a glass particulate reflective film product in which the virtual image is a three-dimensional virtual image, that is, the virtual image is reflected with depth as if it were located behind the surface of the product.

[Conventional technology and problems]

BACKGROUND OF THE INVENTION On the surface of small ornaments such as bells, bells, etc., a beautiful colored reflective film with a glossy color is formed by coating with mineral gold or the like. As a result, when you place bells, bells, etc. in front of your eyes and admire them, the person's face and surrounding scenery are reflected on the surface of the bells, making it beautiful.

However, in the case of conventional bells, bells, etc., the above-mentioned reflective film is formed planarly on the surface of the bells, bells, etc. In other words, since the reflective surface forms the outer surface of the article, the virtual image formed on the surface of the bell, etc. appears to be on the same plane as the surface and is flat. The bell and other items are certainly beautiful, but I couldn't deny that the product was lacking in solidity.

The present invention has been made in view of these drawbacks, and provides a method for manufacturing a glass particulate reflective film product that is provided so that a three-dimensional virtual image appears on the surface of small accessories such as bells and bells, and other various products. The purpose is to provide the following.

[Means for solving problems]

In order to achieve the above object, the method for manufacturing a glass particulate reflective film product according to the present invention includes the steps of vacuum depositing a metal film made of an organic substance (alloy) on the surface of the product forming material to form a light reflective base surface. , a step of attaching colored transparent color clear to the surface of the light-reflecting substrate, a step of attaching a curable adhesive paint containing a non-volatile content to the surface of the color clear, and a step of applying a curable adhesive paint containing a non-volatile component to the surface of the surface in a state where the adhesive paint is semi-cured. a step of uniformly adhering the glass particles to the glass particles; a step of curing the adhesive paint to which the glass particles have been attached; and a step of spraying a transparent adhesive paint containing non-volatile components onto the glass particles by means such as spraying, thereby removing the glass particles. This method is characterized by comprising a step of adhering the adhesive paint to a depth that will fill the adhesive layer, and a step of curing the adhesive paint.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 shows a reflective film 1 of glass particles according to the present invention.
Bell 2 as an example of a small ornament formed on the surface
shows. FIG. 2 is an enlarged cross-sectional view showing how the reflective film 1 is formed, and FIG. 3 is an enlarged view of FIG. 2.

In each figure, 3 is a forming element such as a bell,
On the surface of this forming material 3, a reflective base surface 4 is formed by vacuum-depositing a mineral or alloy (organic substance) film, and a colored transparent thin film color clear 5 is formed thereon.
layers are provided. 6 is thin film color clear 5
7 is a curable adhesive paint adhered to the surface of the adhesive paint 6, glass particles uniformly adhered to the surface of the adhesive paint 6;
Reference numeral 8 denotes a nonvolatile hardening paint that is adhered to the surfaces of the glass particles 7 and the adhesive paint 6 to such an extent that the glass particles 7 are buried therein.

The manufacturing process of the light reflective film product having the above structure will be explained in order.

First, a mineral or alloy film is vacuum deposited on the surface of the forming material 3 by a vacuum thin film manufacturing method to form the reflective base surface 4. Next, a colored transparent thin film color clear 5 is painted on this reflective base surface 4,
Bake at a high temperature of 150℃ or higher.

Thereafter, an adhesive paint 6 containing non-volatile components is applied to the surface of the thin film color clear 5 by means such as spraying, and the adhesive paint 6 is dried until it becomes a semi-cured state.

Next, the forming material 3 is put into a large amount of glass particles 7 stored in a container with an open top, and immediately pulled upward. At this time, the glass particles 7 are uniformly attached to the semi-cured adhesive paint 6 attached to the outer surface of the forming material 3, that is, without any gaps over the entire surface. Note that this glass fine particle 7 is
It is highly transparent, and its size is 5 to 5 in diameter.
A material of about 10μ is used.

After the glass particles 7 are attached to the semi-cured adhesive paint 6 in this way, the forming material 3 is placed in a drying device and heated at 100 to 120°C for about 10 minutes to harden the adhesive paint 6. As a result, the glass particles 7 are firmly fixed to the surface of the adhesive paint 6.

Subsequently, the lower volatile curing paint 8 is sprayed by means such as spraying so that the surface of the glass particles 7 is covered. After that, put the forming material 3 into the drying device for 70 minutes.
The non-volatile curing paint 8 is cured by heating for 20 to 30 minutes while maintaining a temperature of ~90°C, thereby producing a product in which the surface of the reflective film 1 has a hardness of 4 to 5H.

As the non-volatile curing paint 8, an epoxy resin paint, an ultraviolet curing paint, or a special paint containing a large amount of non-volatile matter is usually used. In other words,
Adhesive paints generally do not contain much non-volatile content, but unlike conventional adhesive paints, the adhesive paint 8 used in the present invention contains a large amount of non-volatile content.
Even after such drying, there is little condensation, and by bonding with the adhesive paint 6, the glass fine particles 7 are firmly embedded in the adhesive paint 8 and do not protrude in an uneven manner on the surface. Moreover, this non-volatile curing paint 8 is colorless and transparent.

In the reflective film 1 configured as described above, light incident from above passes through the adhesive paint 8 and the glass particles 7, is reflected by the concave surface portion 9 of the glass particles 7, and is reflected by a large number of glass particles. A deep, three-dimensional virtual image is formed on the concave or convex surface of the article formed by the entire fine particles 7.

In other words, when this reflective film 1 is attached to a forming material 3 such as a small ornamental bell 2 or a bell (not shown) shown in FIG. It exists, and the surface is flat, and it has hardness and ridges, so it is not only beautiful, but also because the virtual image reflected on the object is not on the surface, but is connected deeper to the inside. It is more three-dimensional.

In addition, the present invention is not limited to bells and bells as shown in the embodiments, but also accessories such as necklaces, earrings, pendants, buttons, imitation jewelry, helmets, commemorative cups, and other items that have a hard surface and a reflective surface. It can be applied to the production of various articles such as personal items that are shaped into shapes.

〔Effect of the invention〕

As described above, the glass particle reflective film product manufactured by the method of the present invention includes glass particles of 5 to 10 μm embedded in a transparent adhesive paint.
Since these glass particles are attached to the surface of the forming material of the article, they can be attached to the surface of the forming material reliably and easily, and their hardness is 4-5H, so they do not change quality for a long time. You can keep it without letting it happen.

Further, the surface of the reflective film product to which the glass particles are attached is uniform, and there is a reflective surface at a location deeper than the surface, and incident light is reflected at the concave surface of the glass particles. Therefore, depending on the depth, intensity, and degree of scattering of the light, a deep, three-dimensional virtual image of the forming material emerges, making it possible to produce beautiful, solid, and expensive small ornaments.

Furthermore, the adhesive paint that is applied to the inside and outside of the glass particles sandwiched between them uses a paint that contains a large amount of non-volatile content, and the adhesive paint that is applied to the inner layer is in a semi-cured state. At one point, I decided to attach glass particles to this, so that there was no problem with the adhesion of the glass particles, and
Even in the drying process, the adhesive paint does not condense and the glass particles do not fall off the surface of the forming material.

Therefore, the manufacturing yield is reduced, and not only can reflective film products be manufactured at a lower unit price, but also the uniformity of the reflective film surface can be ensured.
