Description

[Detailed Description of the Invention] Field of Industrial Application [0001] The present invention relates to an interior material having a pearly or metallic tone and a three-dimensional visual effect.

2. Description of the Related Art In the field of interior materials such as floor materials and wall materials, various visual effects have been developed or put on the market, and metallic and pearlescent materials are also known. Such an interior material is one in which a surface layer or an intermediate layer in which a pearl pigment or a metal powder is dispersed is provided and the surface of the interior material is embossed, and the surface embossing causes a feeling of unevenness.

However, the above-mentioned interior material has a problem that the embossing disappears due to wear and dust or the like enters the embossed concave portion and is easily soiled.

DISCLOSURE OF THE INVENTION Problem to be Solved by the Invention The present invention is an interior material that has a pearly or metallic texture and is rich in unevenness even if the surface is flat, and does not reduce the unevenness due to fear of dirt or abrasion. Is provided.

Configuration of the Invention The interior material of the present invention has a transparent layer, which is mainly composed of transparent or translucent synthetic resin, laminated and integrated on a base material; the boundary surface between the base material and the transparent layer has an uneven surface. In addition, the light-reflective powder is dispersed in the light-transmitting layer, or the light-reflective powder is attached to the uneven surface.

EXAMPLE FIG. 1 is a sectional view showing an example of the interior material of the present invention.
A transparent layer 21 is laminated and integrated on a sheet-shaped base material 11. The base material 11 is opaque and can be formed from a hard or soft synthetic resin such as polyethylene, polyvinyl chloride, polycarbonate, polyvinyl alcohol, polyester, or the like, and if necessary, a plasticizer such as dioctyl phthalate or calcium carbonate or the like. A filler, a coloring material such as a pigment, a stabilizer and the like can also be added. The thickness of the base material 11 depends on the use of the interior material and the like, but is generally about 1.0 to 5.0 mm, for example.

The translucent layer 21 is composed of a transparent or semitransparent synthetic resin film in which the light-reflecting powder 31 is dispersed. As the synthetic resin, a hard or soft synthetic resin such as polyethylene, polyvinyl chloride, polycarbonate, polyvinyl alcohol, or polyester can be used, and a plasticizer, a coloring material, a stabilizer and the like can be added if necessary. The thickness of the translucent layer 21 is preferably about 0.1 to 1.5 mm.

As the light-reflecting powder 31, pearl pigment, metal powder, or the like is used, which is kneaded in a synthetic resin. The size and the addition amount of the light-reflecting powder 31 are determined by the base material 11 through the transparent layer 21.
It may be appropriately determined in accordance with the intended design effect within a range that can be visually recognized.

The surface side 21a of the translucent layer 21 is a substantially flat surface, while the substrate 1
The back surface side 21b that comes into contact with 1 is embossed and has irregularities.

Thus, the unevenness is formed at the boundary between the transparent layer 21 and the base material 11, and since the light-reflecting powder 31 is present in the transparent layer 21, the uneven portion of the transparent layer 21 is formed. It has a good metallic reflection and a pearly texture with excellent unevenness. If the light-reflecting powder 31 is not present, light reflection at the boundary is small and the desired unevenness cannot be obtained. Also, the front side
Since 21a is not embossed, the embossing feeling (unevenness) does not decrease due to fear of dirt or abrasion.

In order to form unevenness on the boundary surface between the base material 11 and the transparent layer 21, for example, a synthetic resin film having an uneven pattern on the back surface,
It may be integrated with the base material 11 in a state where the uneven pattern is preserved. As this method, for example, a method of bonding a synthetic resin film having an uneven surface to the base material 11 with an adhesive, the base material 11
There is a method of heating and laminating a concavo-convex synthetic resin film. In FIG. 4, which will be described later, the transparent or semi-transparent layer 23 used as the adhesive layer is the interior material obtained by the above-mentioned joining method. In the case of the heating and laminating method, as shown in FIG. 2, the base material 11 is heated and softened by a heater 33 or the like, and the synthetic resin film 19 having an uneven pattern on the lower surface is laminated at room temperature or at a temperature at which it does not soften. The desired light-transmissive layer 21 can be formed by stacking and integrating with the (concavities and convexities) held. As shown in FIG. 2, by guiding the base material 11 and the synthetic resin film 19 separately up to the front of the press roller 35 (pressing member) and bringing them into contact with each other at the press roller 35, the air existing between the irregularities is formed. Are expelled and stacked to prevent air from remaining at the interface.

Contrary to the above, the base material 11 is previously formed with a concavo-convex pattern, and the base material 11 is kept at room temperature or softening temperature to maintain the concavo-convex pattern, while the light-reflecting powder 31 is used. The synthetic resin film 19 in which is dispersed is heated and softened by a heater or the like, and the synthetic resin film 19 is laminated on the base material 11 to form a light-transmitting layer, thereby forming an uneven surface formed on the base material 11 in advance. By holding it, an uneven surface can be formed on the boundary surface between the base material 11 and the transparent layer 21.

As a further example, a base material 11 having an uneven pattern formed on its surface is prepared in advance, and a synthetic resin paste sol such as vinyl chloride in which the light-reflecting powder 31 is dispersed is applied to the base material 11 and cured. By doing so, for example, as shown in FIG. 1, an interior material having an uneven surface at the boundary surface between the base material 11 and the light transmitting layer 21 can be obtained.

FIG. 3 is a sectional view showing another embodiment of the present invention. Instead of the light-reflecting powder 31 being dispersed in the transparent layer 21, the transparent layer
It is the same as FIG. 1 except that it is attached to the uneven portion of the boundary surface between the substrate 21 and the base material 11, and the same effect as that of FIG. 1 can be obtained.

FIG. 4 is a sectional view showing another embodiment of the present invention. The printed layer 15 and the transparent or semitransparent layer 23 are formed on the base body 13 to form the base material 11, and the light transmissive layer 21 is laminated on the base material 11. The transparent or semi-transparent layer 23 can be formed of the same material as the transparent layer 21. Light-reflecting powder 31 in the light-transmitting layer 21.
Are distributed. It is observed that the printed pattern of the printed layer 15 of the base material 11 is given a pearly or metallic unevenness.

FIG. 5 shows still another embodiment of the present invention. A transparent layer 21 is formed on a base material 11, and an uneven portion is formed on the boundary surface thereof. The base material 11 is composed of a base body 13 and a printed layer 15, and the printed layer 15 is given a feeling of unevenness. The transparent layer 21 is
The surface layer 29, the printing layer 27, and the pearl metallic layer 25 are laminated and configured. The surface layer 29 has a substantially flat surface 29a on the surface side, and can be formed of the same transparent or translucent synthetic resin material as described above for the light transmitting layer. Print layer
27 can change the texture by making it a semi-transparent print pattern, and if it is an opaque print pattern, the uneven feeling of pearly tone or metallic tone can be partially lost in the opaque part. it can. Pearl metallic layer
25, the light-reflective powder 31 is dispersed in the synthetic resin,
It is made of the same material as the transparent layer 21 of FIG.

Effect of the Invention According to the present invention, the boundary surface between the base material and the light-transmitting layer formed on the base material is an uneven surface, and the light-reflective powder is provided inside the light-transmitting layer or on the boundary uneven surface. Even if the outer surface is made smooth by laminating or integrating the light-transmitting layer and the base material by dispersing or adhering, the interior material has a pearly or metallic tone and has an excellent sense of unevenness and an excellent texture. Can be realized. Since this interior material does not require embossing on the outer surface, dirt does not adhere between the embosses and the embossing wear disappears to reduce the unevenness feeling when used.
