Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative board used by being applied to a floor surface or a wall surface, and a method for manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, a decorative board used as a floor material or a wall material using wood as a base material has been manufactured with a large size (width 30 cm, length 180 cm) in order to save construction labor. In recent years, due to widespread use of the direct-adhesion method in which floor materials are directly applied to even slightly uneven floor slabs, and the appearance of high-grade products that look like solid wood of natural wood, small-width or short-length decorative boards are applied. I have more things to do.

[0003]

However, when a small-width or short-length decorative board is constructed, the construction efficiency is poor, and the labor cost is very high due to lack of manpower and soaring labor cost. Therefore, in order to solve the above problems, a method of solving those problems by previously bonding a small-width or short decorative plate to a certain size has been studied, and the bonding portion has flexibility. Methods such as interposing a hot melt adhesive or sticking a flexible sheet (cloth, nonwoven fabric, foamed synthetic resin sheet, etc.) on the entire back surface have been adopted.

However, the method of interposing a hot melt adhesive in the joint portion requires a large amount of the adhesive, and the adhesive has to be applied to each of the decorative boards. Therefore, the raw material cost is high and the manufacturing efficiency is high. However, there was a problem that the price of the decorative plate would be high because of the poor quality. In addition, a method of sticking a flexible sheet on the entire back surface of the decorative plate must be prepared by cutting in advance according to the shape of the decorative plate to be obtained. Peel off from the sheet surface after construction,
There was a problem that the thickness of the whole decorative board became thick.

[0005]

The present invention has been made to solve the above-mentioned problems, and its constitution is a long and wide makeup in which a plurality of unit decorative plates having a coating layer on the surface are connected in series. A plate is formed, and a film made of peelable flexible resin is integrally formed on the entire surface of this long and wide decorative plate, and each unit decorative plate is not fixed to the decorative plate. As a manufacturing method, the synthetic resin liquid is applied to the entire surface of the long and wide decorative board and then dried to integrally form a peelable film, or a peelable integrated film is pressure bonded. It was solved by the method.

[0006]

According to the first aspect of the present invention, a film made of a flexible resin that is peelable over the entire surface of a long or wide decorative plate by joining a small or single unit decorative plate In order to provide a decorative plate in which the unit decorative plates are not fixed to each other, the flexible resin allows the unit decorative plates to conform to the unevenness of the base surface to some extent, and to make it long and wide. This is to improve the workability by doing.
Further, the peelable film is used as a curing film for the purpose of protecting the surface of the decorative plate until the construction is completed.

In claim 2, the male fruit and the female fruit are formed on the opposite side surfaces of the four side surfaces of the unit decorative plate, respectively.
This is because in order to make a wide and long decorative plate, the temporary bonding between the unit decorative plates is improved and the workability of forming a film of a peelable flexible resin and the workability of the decorative plate are improved.

The present invention will be described in detail below. 1 is an enlarged side view showing an embodiment of a decorative board manufactured by the method of the present invention, FIG. 2 is a plan view thereof, and FIG. 3 shows another embodiment.

The small-width or short-length unit decorative board 2 used in the present invention has a large plywood having a thickness of 7 to 15 mm, a width of 91 cm and a length of about 182 cm as a substrate, and a decorative material such as a veneer on the surface thereof. Width is 90 ~ 150 after is attached
After being cut to a length of 300 to 1800 mm, the peripheral part of the side surface is subjected to actual 3 processing for joining, etc. Finally, the entire surface is coated with urethane or aminoalkyd resin paint and dried. A decorative board having a coating layer 1. When the backing material 5 such as a cushion material or a sound insulating material is attached to the back surface of the unit decorative plate 2, it is preferable to attach the backing material 5 at a wide time before the substrate is cut.

The unit decorative plates 2 are made into long and wide decorative plates having desired widths and lengths and shapes by sequentially fitting the actual three parts for joining formed on the respective side surfaces. The size and shape of the long and wide decorative plate are not particularly limited, but in consideration of handling and workability, the width is 250 to 450 mm and the length is 9
The shape is a rectangle, a step shape, a parallelogram shape, or the like.

A peelable flexible resin film 4 is integrally formed on the entire surface of the combined long and wide decorative plate. The releasable flexible resin is formed on the surface of the decorative board by a method such as applying a liquid resin and drying it, or press-bonding or heat-sealing a thin flexible resin film.

When a liquid resin is used, a resin having a flexible film 4 such as an acrylic resin emulsion or a urethane resin emulsion is used. When a resin film is used, a thin film 4 selected from polyethylene resin, polypropylene resin, vinyl chloride resin, styrene resin, acrylic resin, etc., which can be melt-bonded at a relatively low temperature of about 100 to 200 degrees, can be used. A flexible resin film or a flexible thin resin film coated with an adhesive or the like on one side can be used.

As a method for applying the liquid resin, an ordinary applicator such as a flow coater or a spray coater is used to apply the liquid resin over the entire surface of the decorative plate on which the synthetic resin film 1 is formed. The coating amount may be such that the film thickness after drying is about 20 to 100 μm. Drying can be done rapidly with hot air.

In the case of the method of pressure-bonding the film, when a thermoplastic synthetic resin film is used, after covering the upper surface of the decorative plate on which the synthetic resin film 1 is formed with the film, the surface temperature is about 150 to 200 degrees. When hot-melt fusion bonding is performed using a release-treated heat roll, or when using a film with adhesive applied on one side, the pressure-sensitive roll whose surface temperature is room temperature is prepared by stacking the adhesive-coated surface on the surface of the decorative plate. Use and press.
The thickness of the film is preferably about 30 to 100 μm, because the effect as a curing paper is exhibited.
