Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface protective material based on a ceramic inorganic plate such as a fiber reinforced cement plate, a calcium silicate plate or a gypsum plate, which is used as a surface material for building materials or furniture. The present invention relates to a method for manufacturing a coated plate.

[0002]

2. Description of the Related Art In recent years, there has been an increasing demand for a mirror-finished coated plate based on a ceramic inorganic plate used as a surface material for building materials or furniture. There is an increasing number of coated plates having a smooth transparent or translucent top clear layer formed on a decorative layer formed thereon. The top clear layer in such a coated plate is formed by applying a transparent or translucent resin paint with a roll coater, flow coater, spray, etc., and curing it, but in transportation, construction, processing, etc. Since the surface is easily scratched, and if it is scratched, the commercial value is reduced, the surface protection material of paper or a synthetic resin film is attached after manufacturing. The surface protection material is to be removed after completing operations that may damage the surface of the decorative board, such as transportation, construction, and processing.

However, in the production of a coated plate having a top clear layer, air is trapped in the top clear layer at the time of coating the top clear layer and air bubbles are not generated. Was causing it. In addition, attaching a surface protective material to the surface of a painted plate after manufacturing it also greatly reduces production efficiency. Further, in the case of mirror finishing, even if a small amount of dust adheres in the painting process, the appearance becomes poor. Therefore, it is also important to avoid the adhesion of dust in the painting process. In particular, since the substrate is a ceramic-based inorganic plate such as a fiber-reinforced cement plate, a calcium silicate plate, and a gypsum plate, dust is easily generated,
Preventing dust from adhering to the top clear layer has been a very important issue.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve such problems and problems of the prior art, and has as its object to prevent the generation of air bubbles and the attachment of dust in the coating step, and Another object of the present invention is to provide a method for manufacturing a coated plate with a surface protective material, which can efficiently provide a removable surface protective material on the surface of a smooth top clear layer.

[0005]

In order to achieve the above object, the present invention provides a surface protective material comprising a substrate made of a ceramic inorganic plate, a decorative layer, a top clear layer, and a surface protective material. In the method of manufacturing a coated plate, a decorative layer is provided on a substrate, and an ultraviolet-curable resin paint for forming a top clear layer is applied on a film-like surface protective material, and the applied ultraviolet-curable resin is applied. The resin paint and the decorative layer on the base material are joined, and the whole is heat-pressed to integrate the base material, the formed decorative layer, the UV-curable resin paint and the surface protective material, and then irradiated with ultraviolet rays. The top clear layer is formed by curing the UV-curable resin paint.

In the method for producing a coated plate with a surface protective material, an ultraviolet-curable resin paint for forming a top clear layer is applied on the film-like surface protective material, and the applied ultraviolet-curable resin paint is applied. A decorative layer forming coating material layer is provided on the above, the provided decorative layer forming coating material and the base material are joined, and the whole is heated and pressed to form a base material, a formed decorative layer,
After the UV-curable resin paint and the surface protective material are integrated, the UV-curable resin paint is cured to form a top clear layer. Further, in the method for producing a coated plate with a surface protective material, an ultraviolet-curable resin paint for forming a top clear layer is applied on the film-like surface protective material, and the applied ultraviolet-curable resin paint is applied on the applied ultraviolet-curable resin paint. A decorative layer forming coating material is provided, a base coat resin paint is applied on the provided decorative layer forming coating material, the applied base coat resin paint and the base material are joined, and the whole is heated and pressed. After integrating the base material, the formed base coat layer, the formed decorative layer, the UV-curable resin paint and the surface protective material, the UV-curable resin paint is cured to form a top clear layer. is there.

In the above method for producing a coated plate, the film-like surface protective material is preferably a polyethylene terephthalate (PET) film, and the surface of the ceramic inorganic plate constituting the base material is polished. It is preferable that a base treatment such as an impregnated sealer treatment is performed.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A ceramic inorganic plate constituting a substrate is a porous body made of a predetermined size, such as a fiber reinforced cement plate, calcium silicate plate, gypsum plate, or wood chip cement plate. . The surface on which the decorative layer is formed is subjected to a ground treatment such as polishing or impregnated sealer treatment as necessary.
Further, a base coat layer to be described later is provided on the surface of the inorganic plate, if necessary, directly or after a base treatment.

The decorative coating material constituting the decorative layer comprises a pigment (ink) for patterning and a fixing agent (so-called solid material) for fixing the pigment. The method of coating the decorative layer is not particularly limited, but when a mirror-finished coated plate is aimed at, the transfer method is suitable. The transfer method is a method in which a coating material including a pigment (ink) forming a decorative layer and a fixing material for fixing the same is printed on transfer paper or a transfer sheet in advance, and the transfer paper or the transfer paper is heated via a heating roll. This is a method of forming a decorative layer by transferring and fixing a coating material for forming a decorative layer on a transfer sheet by heating and pressing on a base material.
The top clear layer is formed of an ultraviolet curable resin (hereinafter, referred to as a UV resin).

As the surface protective material, a conventional surface protective material,
That is, a protective paper or a protective sheet can be used, but in order to cure the UV resin paint that forms the top clear layer,
UV light is easy to penetrate and absorbs less UV light.
In addition, after the UV resin coating is cured, it should be easily separated from the UV resin. According to the result of the experiment, PET is most suitable as the material of the surface protective material. The thickness of the film depends on the material used,
0 μm to 100 μm is preferred. When aiming for a mirror-finished painted plate, use a smooth film with no scratches or stains on the surface to which the UV resin paint is applied. However, when it is necessary to provide irregularities on the surface of the top clear layer, a film having irregularities on the surface may be used. By making the unevenness of the film very fine, the gloss of the surface of the top clear layer can be adjusted, and furthermore, the gloss can be adjusted to form a translucent top clear layer.

As the UV resin coating for forming the top clear layer, since the decorative layer needs to be visible through the top clear layer, the UV resin coating to be used is basically transparent or translucent (by coloring). The amount of the resin paint applied on the film-like surface protection material is 30 g / m ^2.
Preferably to 80 g / m ^2, whereby the thickness of the top clear layer formed is approximately 30Myuemu～80myuemu. The long and continuous film-shaped surface protection material coated with the UV resin paint is placed on a release paper on the UV resin paint and wound up in a roll shape. In some cases, a coating material for forming a decorative layer is applied on the applied UV resin coating material, and a resin coating material for a base coat is further applied on the coating material for forming a decorative layer.

The base coat layer is provided in accordance with the condition of the base treatment of the inorganic plate as the base material. As the resin coating for the base coat, an acrylic, acrylic urethane, or urethane resin coating can be used. The thickness of the base coat layer is preferably in the range of 30 μm to 80 μm. It is difficult to use a UV resin paint as the base coat resin paint because it is difficult for the UV paint to reach the base coat resin paint through the UV resin paint and the decorative layer forming coating material from above the surface protective material. Not preferred.

In the manufacturing process, if necessary, a base layer is formed on a base coat layer of a ceramic inorganic plate on which a base coat layer is formed, and a decorative layer is formed on the base coat layer. UV resin paint applied on a film-like surface protection material and release paper placed on its surface,
Bonding is performed while removing the release paper, and the whole is heated and pressed by a heating roll or the like. By this heat compression bonding, the base material, the decorative layer, the UV resin paint and the surface protective material are integrated.
At the time of joining and thermocompression bonding, care must be taken so that wrinkles do not occur in the film which is a surface protective material.

The heating temperature at the time of thermocompression bonding depends on the material of the inorganic plate constituting the base material and the type and thickness of the film as the surface protective material.
A range from 0 ° C to 200 ° C is preferred. Further, the pressure of the heating roll is preferably in the range of 1 kg / cm to 5 kg / cm in linear pressure. Then, it is irradiated with ultraviolet light,
The resin coating is cured to form a top clear layer. Note that a normal mercury lamp or a metal halide lamp is used as the ultraviolet light source. UV irradiation is usually 8
This is carried out by using a few UV lamps of 0 to 120 W / cm and passing UV resin paint under these lamps at a speed of 5 to 15 m / min.

[0015] The film, which is a surface protective material, is kept attached to the formed top clear layer. Therefore, it can be used as it is as a surface protection material,
After completing work that easily damages the surface, such as transportation, construction, and processing, it can be easily removed. Note that, in the above-described process, there is no opportunity to generate bubbles or adhere dust to the top clear layer, and the appearance does not become poor due to the adhesion of bubbles or dust.

Further, a layer of a coating material for forming a decorative layer is provided on a UV resin coating applied to a film as a surface protective material, and the layer of the coating material for forming a decorative layer is optionally provided on a base coat. Layer, and the whole is heat-pressed with a heating roll or the like, and the base material, the base coat layer, the formed decorative layer, U
V resin paint and surface protection material are integrated. The substrate made of an inorganic plate is preferably preliminarily heated, and a resin coating material serving as an adhesive is preferably applied to the surface of the base coat layer as needed. The temperature of the heating roll is preferably in the range of 140 ° C. to 200 ° C., and the pressure is preferably in the range of 1 kg / cm to 5 kg / cm.

Next, ultraviolet rays are irradiated to cure the UV resin paint to form a top clear layer. The film, which is the surface protective material, is kept attached to the formed top clear layer, so it can be used as it is as it is as a surface protective material and completes the work that easily damages the surface such as transportation, construction, processing, etc. After that, it can be easily removed. Therefore, there is no opportunity to generate air bubbles or attach dust to the top clear layer, and the appearance does not deteriorate due to the attachment of air bubbles or dust or scratches.

Further, a resin coating for base coat is applied on a layer of a coating material for forming a decorative layer provided on a UV resin coating applied to a film which is a surface protective material. And the whole is heat-pressed with a heating roll or the like. By this heat compression bonding, the base coat resin coating and the decorative layer forming coating material are cured to form the base coat layer and the decorative layer, and the base material, the formed pace coat layer, the formed decorative layer, the UV resin coating and the surface It is integrated with the protective material. In this case, the substrate made of the inorganic plate is preferably heated in advance, and the surface of the substrate that has been subjected to the base treatment is
If necessary, a resin paint serving as an adhesive can be applied.

Next, the resin is irradiated with ultraviolet rays to cure the UV resin paint, thereby forming a top clear layer. The film, which is the surface protective material, is kept attached to the formed top clear layer, so it can be used as it is as it is as a surface protective material and completes the work that easily damages the surface such as transportation, construction, processing, etc. After that, it can be easily removed. Thus, according to these steps, since the application of the UV resin paint for forming the top clear layer becomes the attachment of the surface protective material, not only the influence of dust in the manufacturing process can be minimized, but also The surface protection material can be efficiently attached, and the production efficiency of the coated plate with the surface protection material can be improved.
