Description

[Detailed description of the invention] This invention relates to decorative materials, and more specifically, the present invention is a decorative material that has polarization properties, that is, the color tone changes depending on the viewing angle, and has a rich three-dimensional effect, as well as a sense of transition of shine found in natural precious woods. Regarding 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 sense of transition and depth of shine that is unique to natural precious wood by simply using a conventional printed pattern.

This invention was made in view of the above, and
When it has polarization and a pattern,
The purpose is to provide a decorative material that adds depth to this.

The decorative material according to the present invention is characterized in that a transparent to semitransparent resin layer in which titanium dioxide-coated mica is dispersed is laminated on a semitransparent to opaque base material layer.

Embodiments of the present invention will be described below based on the drawings.

First, in FIG. 1, the base material layer 1 must be semitransparent to opaque, and may be made of paper, woven fabric, nonwoven fabric,
It is formed from a 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. In the present invention, it is convenient for the manufacturing process to bond the base material layer with a titanium dioxide-coated mica-dispersed resin layer 2 to be described later to form a decorative material. Therefore, the base material layer is preferably combined with the above-mentioned resin layer. A material with excellent thermocompression bondability is used.

Titanium dioxide coated mica 3 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
A material having a diameter of about 0.2 to 0.6 μm is used 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 10 per 100 parts by weight of the resin composition)
Parts by weight, from 0.1 to 0.1 in terms of workability and design effect.
5 parts by weight is preferred.

The titanium dioxide-coated mica-dispersed resin layer 2 is preferably manufactured by a calendering method, and as the resin, thermoplastic resins such as polyvinyl chloride, polyethylene, and polypropylene are preferably used.
The thickness of the resin layer is not particularly limited, but is usually 0.05
~2mm. The decorative material of the present invention can be obtained by thermocompression bonding such a resin layer 2 to the base material layer 1 and laminating them. However, the lamination method is not limited to thermocompression bonding, and other known methods may be used.

FIG. 2 shows another embodiment of the present invention, in which the base layer 1
A pattern layer 4 is provided between the resin layer 2 and the resin layer 2. This pattern may be an abstract pattern or a wood grain pattern, and the pattern layer is formed by printing on the top surface of the base material layer or the back surface of the resin layer 2, for example. The pattern layer can also be formed by laminating a transparent film with a pattern printed in advance between the base layer and the resin layer.

FIG. 3 shows yet another embodiment of the present invention, in which a transparent or translucent surface layer 5 is laminated on the resin layer 2. This is to protect the resin layer and give a more three-dimensional effect and depth to the pattern expressed by the resin layer itself.

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 The surface of the surface layer can be semi-matte or glossy 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 this embodiment, the pattern layer 4 has a second
As shown in the figure, it may be provided between the base material layer 1 and the resin layer 2, but as shown in FIG. 3, it may also be provided between the surface layer 5 and the resin layer 2.

As described above, the decorative material of the present invention is constructed by laminating a transparent to semitransparent resin layer in which titanium dioxide-coated mica is uniformly dispersed on a semitransparent to opaque base material layer. , titanium dioxide-coated mica has polarizing properties, and the color tone of the decorative material changes subtly depending on the viewing angle, giving the decorative material depth and three-dimensionality. In addition, when the pattern layer is laminated, the pattern layer is observed against or through the resin layer in which titanium dioxide-coated mica is dispersed, which gives a sense of polarization and transition of shine. It has depth and a rich three-dimensional effect, and especially when the design is a wood grain pattern, in addition to the three-dimensional effect, a transitional feeling of shine peculiar to precious wood is produced, and a high-quality decorative material can be obtained.
