Description

[Detailed explanation of the invention] This invention relates to decorative materials, and more specifically, it has polarization, that is, the color tone changes depending on the viewing angle, and it has a rich three-dimensional fiber texture, as well as a sense of transition of shine seen in natural precious woods. The present invention relates to decorative materials.

In recent years, decorative materials with various abstract patterns and wood grain patterns have been widely used for interior decoration boards, furniture and home appliance exterior boards, etc. However, the color tone is constant and monotonous regardless of the viewing angle, and the design Even if it has a pattern, it generally lacks depth and gives the impression of being a cheap product. In particular, in the case of wood grain patterns, it is not possible to provide the fiber texture, three-dimensional effect, and transitional feel of shine that are unique to natural precious wood by simply using a conventional printed pattern.

This invention was made in view of the above, and
In addition to having polarizing properties, it has a three-dimensional fiber texture and a sense of transition in shine, and if it has a design pattern, the pattern has depth, and if it has a wood grain pattern, it has a fiber texture and shine that are unique to natural precious woods. The purpose of the present invention is to provide a decorative material that has a transitional feel.

The decorative material according to the present invention has a resin layer in which (a) titanium dioxide-coated mica and (b) inorganic fibers and/or organic fibers are dispersed laminated on a translucent to opaque base material. It is characterized by

The present invention will be described below based on drawings showing embodiments.

FIG. 1 shows an embodiment of the present invention, in which titanium dioxide-coated mica 2 and inorganic fibers and/or organic fibers 3 (hereinafter simply referred to as fibers) are coated on a translucent to opaque base material layer 1. A resin layer 4 is laminated in which .

The base material layer 1 is formed from paper, woven fabric, nonwoven fabric, resin sheet, or the like. The resin sheet may be made of either thermoplastic or thermosetting resin, such as polyvinyl chloride, polyethylene, polypropylene, ethylene-vinyl acetate copolymer resin, polyester, polyurethane, and the like. However, in the present invention, it is advantageous in production to bond the base material layer with a resin layer 4, which will be described later, by thermocompression, and thermoplastic resins such as polyvinyl chloride, polyethylene, and polypropylene are preferably used.

Titanium dioxide coated mica 2 used in the present invention
is a type of coloring agent called interference color type, and it gives various reflected colors depending on its particle size, titanium dioxide coverage, and mica thickness.
~130μ, titanium dioxide coverage 20~55%, mica thickness 0.2~0.6μ depending on the desired color tone. The amount of titanium dioxide-coated mica to be added to the resin is appropriately selected depending on the hue, resin layer thickness, desired degree of interference, etc. 0.05 to 100 parts by weight of the resin composition)
10 parts by weight, and 0.1 in terms of workability and design effect.
~5 parts by weight is preferred.

In the present invention, among the fibers 3 dispersed in the resin layer together with the titanium dioxide-coated mica, glass fibers, metal fibers, ceramic fibers, etc. are used as the inorganic fibers, and short glass fibers are preferably used. The diameter of the short glass fibers is not particularly limited, but in order to express the texture of the fibers, it is preferably about 5 to 20 mμ, and the length is preferably about 0.5 to 20 mm.

Examples of organic fibers include natural fibers such as cotton and silk, rayon, cotton wool, human silk, polyester fibers,
Semi-synthetic and synthetic fibers such as polyamide fibers, acrylic fibers, polyvinyl alcohol fibers can be used, but are not limited thereto. For the same reason as above, the diameter and length of the organic fibers used are as follows:
Approximately 0.5 to 5 denier and 0.5 to 20 mm are appropriate.

This resin layer 2 is preferably manufactured by a calendering method, and thermoplastic resins such as polyvinyl chloride, polyethylene, and polypropylene are preferably used as the resin. Although the thickness of the resin layer is not particularly limited, it is usually 0.05 to 1 mm. By forming the resin layer by calendering, the fibers can be oriented in the longitudinal direction of the resin layer, so the decorative material of the present invention effectively exhibits a directional fiber texture. The blending ratio of the fibers is 0.5 to 50 parts by weight, preferably 1 to 20 parts by weight, per 100 parts by weight of the resin (or the resin composition if the resin contains a plasticizer, filler, or other additives). Note that the fibers may be colored.

In the decorative material of the present invention, the resin layer is made of inorganic fibers,
In particular, when glass fiber is contained, the glass fiber exhibits a hammer tone pattern, and when organic fiber is contained, a silk-like flowing pattern appears, and moreover, the polarizing titanium dioxide-coated mica produces a glare effect. Combined with the sense of transition, the above pattern gives a three-dimensional feel, rich depth, and a high-class image.

In the present invention, as shown in Fig. 2, in order to protect the resin layer 4 and give deeper and three-dimensionality to the pattern expressed by the resin layer itself, a transparent or semi-transparent surface is provided on the resin layer. Layer 5 can be laminated.

The surface layer may be formed from either thermoplastic or thermosetting resin, but preferably the resin layer 4
For example, a thermoplastic resin such as polyvinyl chloride is suitable because it is thermocompression bonded to the material. The surface layer may be colored as necessary. In this case, the colorant has a hiding power that does not inhibit transparency or translucency so that the resin layer can be seen through the surface layer against the background of the base layer 1. selected from those with Incidentally, the surface of the surface layer can be semi-brushed or varnished to give a luxurious feel to the decorative material. If desired, a thermosetting resin such as a melamine resin, diallyl phthalate resin, or polyester resin may be used as the surface layer, and an ultraviolet curable resin may also be used if necessary.

In the present invention, preferably, as shown in FIG. 3, a pattern layer 6 is provided between the resin layer 4 and the surface layer 5.
will be provided. This pattern may be an abstract pattern or a wood grain pattern, and the pattern layer is formed by printing on the surface of the resin layer 4 or the back surface of the surface layer, for example. In addition, by laminating a transparent film with a pre-printed pattern between the surface layer and the resin layer,
A patterned layer can be formed. Also, the fourth
As shown in the figure, the pattern layer 6 may be provided between the base layer 1 and the resin layer 4, and the surface layer 5 may be laminated on the resin layer.

As described above, the decorative material of the present invention is constructed by laminating a transparent or semitransparent resin layer in which titanium dioxide-coated mica and fibers are uniformly dispersed on a semitransparent to opaque base material layer. Therefore, titanium dioxide-coated mica has polarizing properties, and the color tone of the decorative board changes depending on the viewing angle, as well as giving it a three-dimensional effect, depth, and
A transitional sense of shine appears, and the glass fibers create a hammer tone pattern, and the organic fibers create a silk-like flow pattern, resulting in a decorative material with a progressively updated and luxurious image. be able to. When a pattern is applied, the color tone of the pattern changes subtly depending on the viewing angle due to the polarization of the titanium dioxide-coated mica, the sense of transition of light, and the texture of the fibers, and the pattern has a three-dimensional effect and depth. This makes the decorative material even more luxurious.

In particular, when a wood grain pattern is used as a pattern, the polarization of titanium dioxide-coated mica creates a transitional shine unique to natural wood, and the fiber texture and wood texture create a decorative material similar to natural wood. can be obtained. In addition, when the surface layer is laminated,
The surface of the decorative material is protected, and the depth and three-dimensional effect are further enhanced.
