Description

A decorative flooring having hologram pattern and the method of manufacturing pretty}

The present invention relates to a flooring material having a hologram pattern and a method of manufacturing the same, and more particularly, to give a hologram pattern to the entire surface of the upper surface treatment layer by embossing the upper surface treatment layer with a holographic pattern embossing film, or The bottom decorative material which transfers the formed thermal transfer film on the transparent skin layer and forms a wide hologram pattern layer by laminating a hologram pattern layer on the entire upper surface of the transparent skin layer, so that the printed pattern and the hologram pattern of the printed layer are combined. It relates to a manufacturing method.

Here, the hologram is a photo by holography, which is a photographing method using interference of light. In other words, a hologram is a three-dimensional image taken by a laser.

The hologram will be described in more detail as follows.

The coherent light from the laser light source is divided into two beam splitters, and one of the beams causes the object to shine. When the light is diffusely reflected from the surface of the object, it reaches the holographic photosensitive material. It is called object light, and the other light is diffused through the lens to directly shine onto the holographic photosensitive material. This light is called reference light.

In this case, the object light and the reference light interfere with each other on the holographic photosensitive material to produce 500 to 1500 very delicate and complicated interference patterns per mm, and the pictures of the interference patterns are called holograms.

When a beam such as the reference light is applied to the hologram formed as described above, the interference pattern acts as a diffraction grating, and the light is diffracted at a position different from the direction in which the reference light is incident. It is like a reflection of light, which reproduces the first object light in the hologram.

Therefore, if you look inside the regenerated wavefront, you see the first object, but it looks as if the object is in there. If you move the point again, the position of the object changes, as if you were viewing a three-dimensional image. Also, because the wavefront of the original object is regenerated, it can interfere with the wavefront from a slightly deformed object.

Conventionally, in the case of a flooring material using a hologram, when looking at the Utility Model No. 98-7040, it can be seen that it was published under the title of "floor material using a chip with a hologram embedded therein," as shown in FIG. Consisting of the printing layer 23, the adhesive layer 26, and the transparent upper layer 27 in order from the bottom to the base impregnation layer 10 on the base impregnation layer 10, and lower foaming under the substrate impregnation layer 10. It is a floor covering having a layer 31.

The manufacturing method is briefly described. After stacking the substrate impregnated layer 10, the printed layer 23, and the adhesive layer 26 in order, the chip 28 is spread on the adhesive layer 26 using a spreader. Next, the transparent upper layer 27 is coated, and then the lower foaming layer 31 is laminated. At this time, the chip 28 is suitable for the hologram 28 'to a resin, a plasticizer, a stabilizer, a foaming agent, a pigment, or a pearl pigment. They are mixed in proportion, melted using a half-barrier mixer or extruder, and then molded using a calender, then pulverized or heat-mixed on a compound to form a amorphous or amorphous form. The hologram 28 'used here is a sheet made by vacuum evaporation of aluminum on a predetermined film, and refers to a sheet of which both surfaces shine with silver foil or gold foil.

That is, the transparent upper layer 27 of the floor decoration material using a conventional hologram includes a chip 28 formed by administering a pigment or pearl pigment and the hologram 28 'together, and the hologram 28 only at the chip 28 portion. Because the effect was shown in '), it could give its own sense of quality, but it could not express various three-dimensional effects in which the printed pattern was changed according to the viewing angle because the printed pattern and the hologram pattern of the printed layer 23 were combined.

Therefore, in the present invention, the holographic pattern embossing film is embossed on the upper surface treatment layer to give a hologram pattern on the entire surface of the surface treatment layer, or the heat transfer film having the hologram pattern formed on the transparent skin layer is transferred to the upper part of the transparent skin layer. By forming a hologram pattern layer by laminating a hologram pattern layer on a surface, it is intended to provide a flooring material and a method of manufacturing the printed pattern of the printed layer and the hologram pattern.
