Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention is a board material for floorboards and wainscoting having a board surface of natural wood, which has the appearance and feel of natural wood and has excellent flexibility. This invention relates to a decorative panel that does not crack or tear, is moisture resistant, and is durable.

(Prior art) Traditionally, natural wood has been used for floorboards, wainscoting, etc., but the recent rise in the price of wood has increased costs, and it has also been difficult to match the wood grain, so natural wood has been used for floorboards, wainscoting, etc. Some were constructed by printing on or using Norium or other materials, and these were pasted onto base materials such as floorboards and wainscoting.

(Problems to be Solved by the Invention) However, the above material does not have hygroscopicity, has a sticky surface, is uncomfortable to the touch, and is slippery, making it dangerous when used as a flooring material, and the appearance is made of natural wood. There were problems such as inferiority.

(Means for Solving the Problems) The present invention was provided to solve the above problems, in which a relatively thin sheet-like veneer 1 is polymerized and bonded with a thermoplastic resin film 2 on the back side, This is a decorative panel A in which a decorative piece board 3 is cut into a certain size, and the decorative piece board 3 is assembled and stretched onto a relatively thick synthetic resin sheet 4 using the resin film 2 as an adhesive surface. It has the same appearance and feel as natural wood veneers, and has rot resistance, water resistance, etc.

(Example) The drawing shows a typical example of the present invention, where 1 is a sheet-like plywood board made of relatively thin natural wood with a thickness of 0.1 to 0.3 mm, and 2 is a sheet-like veneer made of PVC, etc. 0.1 to 0 of thermoplastic resin
．． It is a film with a thickness of 8 cm, and 5 is a thin reinforcing fabric made of cloth, paper, or cloth and paper. Wood veneer l and resin film 2
The resin film 2 is thermally fused to the veneer l by pressing the resin film 2 onto the veneer l using a thermocompression roll. Further, the resin film 2 may contain a cellulose-based fine aggregate, and in this case, the resin film 2 surface is sanded to make it a rough surface to improve adhesion. The reinforcing fabric 5 is also bonded to the resin film 2 by heat fusion using a thermocompression roll, but this is not used especially when there is no need for reinforcement.

Next, the decorative veneer 1, the resin film 2, and the reinforcing fabric 5 were polymerized and bonded together, and then subjected to heat curing (namashi) treatment and then placed on a rolling board to remove the internal stress that causes warping, bending, etc. Thereafter, it is cut to a required fixed size to form a decorative panel board 3, which is assembled to a relatively thick synthetic resin sheet 4 according to the purpose and folded to form a decorative panel A.

As the synthetic resin sheet 4, a soft thermoplastic resin sheet such as vinyl chloride, a semi-hard thermoplastic resin sheet such as nylon or Teflon, or a foamed sheet such as urethane foam is used when particularly cushioning properties are required.

(Effects) This invention is constructed as described above and has a sheet-like veneer as the surface, so it has an appearance similar to that of a natural wood veneer itself, and has the same hygroscopic feel. It has a moderate amount of frictional resistance, feels good to the touch, and unlike synthetic resins, it has a warm feel.

In addition, the resin film soaks into the natural wood sheet veneer, resulting in tight adhesion and flexibility, which prevents cracking or tearing.Also, since the lower layer is a synthetic resin film, it can withstand water damage. It does not expand or contract and is durable against corrosion, etc.

Furthermore, the decorative panels are made of decorative pieces of a certain size that are assembled onto thick synthetic resin sheets at the factory, so there is no need to attach plywood boards at the construction site, and the decorative panels can be cut with a cutter. By simply gluing it together, the work time can be shortened, and the tatami mats of the decorative board in the factory can be of high quality and uniformity, and the design is excellent, increasing efficiency.
