DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative plastic sheet, and more particularly, to an inexpensive plastic decorative sheet having a suede-like design as an exterior sheet for building materials, equipment, furniture, home appliances and the like.

[0002]

2. Description of the Related Art Conventionally, as a method of industrially producing a suede-like plastic decorative sheet having a calm texture and a soft feeling, soft fine particles made of urethane resin or silicone resin are added. Is applied to the plastic film surface and the beads are arranged on the film surface to form fine uneven surfaces.However, this method is an ink coating method, and the plastic film is It is said that deterioration of physical properties is caused, and the coating film is apt to fall off due to insufficient coating force with the film surface, and that both a plastic film manufacturing process and a coating process are required, so that the manufacturing cost is increased. There's a problem.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and the gist of the present invention is to provide a transparent plastic material having a particle size of 2 to 10 which is incompatible with the transparent plastic material.
A semi-transparent to opaque colored base film is laminated by heating and fusion-bonded to an upper film formed by mixing and forming 0.5 to 6% by weight of colored beads having a size of 0 micron. It is a plastic decorative sheet characterized in that the surface is matte-finished by embossing.

[0004] The thickness of the upper film layer constituting the plastic decorative sheet of the present invention is 0.05 to 0.3 mm, and a single layer obtained by mixing and dispersing 0.5 to 6 wt% of spherical fine-particle colored beads. In addition to the above, a multi-layered structure in which the lamination side with the base film layer is a bead mixed layer and the opposite side (surface side) is a transparent plastic layer may be used. In addition, at the laminating interface between the upper film and the underlying film,
It may be a transparent plastic film printed on the upper film side, in which an intermediate film layer having compatibility with both the upper film and the base film is formed.

[0005] The colored beads in the transparent plastic material composing the upper film layer include plastic materials such as urethane beads and acrylic beads that are arbitrarily colored,
An inorganic material such as a hollow or solid spherical fine particle ceramic is used. In the former case, beads which are incompatible with the transparent plastic material may be selected according to the kind of the transparent plastic material. The amount of the beads to be added to the transparent plastic material is equivalent to 0.5 to 6 wt%, and if the amount is outside the above range, deep taste cannot be obtained.

The relationship between the thickness of the upper film layer and the amount of the colored beads is such that when the film thickness is 0.05 mm, the amount of the beads is 2 to 6 wt% (preferably 4 watts).
t%), 0.1 mm, 1-4 wt% (preferably 2 wt%), and 0.2-0.3 mm, 0.1 wt%.
Setting the mixing ratio to about 5 to 2% by weight (preferably 1% by weight) is more effective in terms of decorativeness.

The average particle size of the beads mixed in the upper film layer is 2 to 100 μm, preferably 20 to 40 μm.
If the average particle diameter is less than 2 microns, a suede feeling cannot be obtained. If the average particle diameter exceeds 100 microns, pinholes are likely to be formed due to falling off from the upper film surface, which is not preferable.

On the other hand, as the base film to be laminated on the upper film, a translucent to opaque plastic material which is compatible with the transparent plastic material used for the upper film and is arbitrarily colored is used.

[0009] Then, on the upper film surface side of the laminated sheet obtained by laminating the above-mentioned upper film and base film,
Preferably 15-80 microns in depth, 15-30 pitch
By heating and pressing a roll surface having an embossed pattern on the order of microns, the product of the present invention having a matte surface having a suede tone can be obtained.

[0010]

According to the present invention, the appearance is enhanced by uniformly dispersing spherical fine-particle colored beads incompatible with the transparent plastic material in the upper film layer,
A suede-like soft feeling is obtained by making the base film laminated on the base film a translucent to opaque colored layer, and a synergistic effect by laminating the base film and the base film, and a base film By embossing the surface side of (1), a decorative sheet having excellent design quality and appearance quality can be obtained.

[0011]

The present invention will be specifically described below with reference to examples. Average particle size of about 20 to transparent polyvinyl chloride resin
Acrylic beads having a thickness of 0.1 μm and having a thickness of 0.1 mm were formed by a film extrusion molding method.

On the other hand, a total of 5 wt% of titanium chloride, other carbon black, polyazo pigment, etc.
Obtain an opaque compounding composition obtained by adding a considerable amount, and using the resin composition, a film thickness of 0.1 mm by a film extrusion molding method.
Was formed.

Next, a top film is superimposed on the above base film, and heated and pressed at 180 ° C. to an embossing roll having an embossed pattern with a depth of 50 to 70 μm and a pitch of 15 to 20 μm on the surface, so that the surface becomes deep. Suede-like product of the present invention was obtained.

[0014]

Since the present invention has the above-described structure, the following effects can be obtained. That is, the product of the present invention is a laminated sheet of an upper film formed by mixing and dispersing colored beads in a transparent plastic material, and a translucent or opaque base film, and a surface side of the upper film of the laminated sheet. By embossing, a decorative sheet having a deep appearance and an excellent appearance quality with a suede-like soft feeling can be obtained. Since there is no need for a coating step of applying a coloring ink, there are effects such as a low manufacturing cost.
