Description

[Detailed Description of the Invention] The present invention relates to an interior building material and a method for manufacturing the same, and its purpose is to use tiles, glass, and other non-metallic substrates as materials, and to produce a special material with a metallic appearance rich in luster. The object of the present invention is to provide a novel interior building material having a surface and excellent adhesion and hardness in a laminated state, and a manufacturing method for mass-producing the same with high efficiency.

Hereinafter, the structure of the present invention will be described in detail based on the illustrated embodiments. In FIG. The substrate 2 is a plating layer of metal or alloy that is deposited and integrated on the surface of the substrate 1 by ion plating (ionized electrostatic plating). Generally speaking, the surface has a metallic-like solid feel to it. Although the figure suggests a simple smooth surface as the surface of the substrate 1, the plating layer 2 can of course be formed on an uneven surface, a curved surface, or the like. 3 is a top coat layer that is integrally laminated by applying an ultraviolet curing paint to the surface of the plating layer 2, and this is preferably colored by the paint, so that a so-called plain makeup without a printed pattern is formed. The interior building material with the surface will be completed.

In this regard, the illustrated embodiment shows the present invention applied to semi-porcelain non-porcelain interior tiles as the interior building material, but as shown in FIG. The surface of the substrate 1 is cleaned by Parker treatment or the like to remove impurities such as oil, moisture, dust, and fingerprints adhering to the surface. Then, the substrate 1 is used as a substrate, and aluminum, nickel, chrome, etc.
In order to deposit and integrate the plating layer 2 on the surface of the substrate 1, ion plating (ionized electrostatic plating) is performed using copper, other metals, or alloys as evaporated substances in the step shown in FIG. In that case,
The plating layer 2 can be made of gold plating or silver plating, for example, and the top coat layer 3 can be made of a transparent paint film to reveal the gold or silver color, but this makes the product relatively expensive and cannot be mass-produced. Since the maximum effect cannot be obtained, it is practical to provide the gold or silver appearance with a colored paint of the top coat layer 3, preferably as an inexpensive common plating layer 2 such as aluminum.

Plating step b using the above ion plating
After that, as shown in step c in FIG. 3, the surface of the plating layer 2 is coated with an ultraviolet curing paint in the form of a uniform film using a roll coater, spraying, or other coating means, and the top coat layer formed thereby 3 is then cured by irradiation with ultraviolet light from an ultraviolet lamp or the like in step d in the same figure. In the intermediate step e between the coating step c and the irradiation step d,
If the entire substrate 1 is heated with a heater or the like, the adhesion strength between the plating layer 2 and the top coat layer 3 can be further improved.

Next, FIG. 2 relates to an interior building material having a decorative surface with a colored printed pattern.
At the same time, a transparent top coat layer 3 made of ultraviolet curing paint is laminated and integrated on the surface of the printing layer 4, and the desired printed pattern can be seen through the top coat layer 3. It's becoming like that.

Therefore, when manufacturing this interior building material, the fourth
As shown in the figure, in an intermediate step f between the plating step b by ion plating and the coating step c of the top coat layer 3, silk screen printing is performed on the plating layer 2, thereby creating a desired colored printed pattern. is given. In this case, the heating step e using a heater or the like not only increases the adhesion strength between the plating layer 2 and the top coat layer 3 described above, but also contributes to the early drying effect of the printing ink or dye, thereby improving mass productivity. Of course, the above steps can be performed automatically and continuously using one device.
Note that the interior building materials in Figures 2 and 4 and other configurations of their manufacturing methods are substantially the same as those in Figures 1 and 3, so the corresponding symbols in Figures 2 and 4 are used in Figures 1 and 3. The detailed explanation will be omitted.

In any case, in the interior building material of the present invention, the plating layer 2 is formed by the ion plating method, so that the non-metallic material substrate 1
Therefore, it has excellent fixing force and hardness. Since the plating layer 2 is applied using the ion plating method, the above effects can be obtained without being restricted by the material. With the plating layer 2, it is possible to finish the interior building material with a metallic-like decorative surface rich in luster, and of course, it will not rust.

In addition, various colors and transparent solvents can be freely selected as the paint for the top coat layer 3, which is useful for obtaining decorative changes as an interior building material. , it becomes even more effective. Since the paint cures when exposed to ultraviolet rays, the top coat layer 3 can be laminated and integrated instantly, and in this sense, it is also excellent in mass production, making it easy to create new interior building materials. This can be said to be a practical invention as it can be manufactured quickly.
