(Field of Industrial Application) The present invention relates to a natural wood composite board, and more particularly to a composite board in which a decorative veneer (backing board) is adhered to one side of a composite base material in which glass fiber or the like is adhered to both sides of a cork board. (Prior technology) Sound absorbing boards with a porous structure have traditionally been used for the walls and ceilings of acoustic halls, and recently, the porous nature of cork has been used to bond decorative veneers to cork boards. Composite boards have also been used as this type of wall or ceiling board. (Problem that the invention aims to solve) However, when a decorative veneer is simply glued to a cork board, warping or cracking occurs in the veneer itself or the cork board itself due to drying or moisture absorption, making the cork board There were problems such as peeling of the veneer, warping due to shrinkage of the paint film caused by the coating on the surface of the decorative veneer, and poor appearance over time. (Means for Solving the Problems) The inventor of the present invention conducted studies to solve the above-mentioned problems, and developed a material that uses moisture absorption and drying properties such as glass fibers, polyamide (aramid) fibers, or carbon fibers on both sides of the cork board. We focused on the fact that a good quality natural wood composite board could be obtained by gluing a fiber cloth that does not change its fiber length even when the cork board is worn, suppressing the warpage or knots of the cork board, and gluing a decorative veneer on top of this. He completed this idea. In other words, the present invention uses a decorative veneer on one side of a composite substrate made by adhering glass fiber cloth, polyamide (aramid) fiber, or carbon fiber cloth to both sides of a cork board with a thickness of 1 to 10 mm via an adhesive. Glued,
It is a natural wood composite board. (Function) The present invention particularly involves bonding glass fiber, polyamide (aramid) fiber, or carbon fiber cloth to a cork board and using this as a composite base material.
These glass fibers, polyamide fibers, or carbon fibers do not change even when absorbing or dehumidifying moisture, and can prevent the cork board from knotting or warping, as well as preventing the decorative veneer itself from knitting or warping. This can also prevent cracking due to (Example) The natural wood composite board of the present invention will be explained in more detail below with reference to the drawings. FIG. 1 shows a cross-sectional view of one embodiment of the natural wood composite board of the present invention. That is, the natural precious wood composite board 1 of the present invention is one in which a decorative veneer 2 is adhered to one surface of a composite board 9 via an adhesive 3, and such a composite base material 9 is made by bonding adhesives 5 and 7 to both sides of a cork board 6. It is made by adhering glass fiber cloth, polyamide (aramid) woven cloth, or carbon fiber cloth 4 and 8 through a . In this case, the decorative veneer 2 is made of various precious woods such as Japanese cypress, Japanese oak, Japanese cypress, cherry tree, elm, etc., imported materials such as teak, rosewood oak, mahogany, zebra wood, etc., with a thickness of 0.15 to 0.40 mm This is a backing plate cut as thin as the thickness. Note that the decorative veneer 2 in the present invention is not limited to a backing board, and may be a laminated (artificial heathered) veneer. Adhesives 3, 5, and 7 are thermosetting or thermoplastic adhesives, which are formulated for decorative veneers so that the adhesive itself does not ooze out onto the surface of the veneer during the pressing process. For example, water-soluble melamine resin, styrene-butadiene resin, etc. may be used. In this case, the amount of adhesive is, for example, in the case of adhering the veneer 2 and the composite base material 9, the basis weight is 110 to 130 g/m 2
When adhering the glass fiber cloths 4, 8 and the cork board 6, the basis weight is 110 to 130 g/ m2 . The glass fiber cloth, polyamide (aramid) woven cloth, or carbon fiber cloth 6 constituting the composite base material 9 has voids that can be impregnated with the adhesives 5 and 7 in a fluid state, and the average The weight is about 30-120g/ m2 , and the average thickness is 0.2-0.4
Non-woven fabric or cloth is used in the form of sheets or mats of about mm. Further, as the cork plate, a cork plate obtained from natural cork or one obtained by compression molding small granular cork by ordinary means can be used, and a thickness of 1 to 10 mm is preferable. The natural wood composite board 1 of the present invention has a laminated structure as described above, and is specifically manufactured by the following manufacturing method. That is, adhesives 5 and 7 are applied to both sides of a cork board 6, and a glass fiber cloth, a polyamide (aramid) woven cloth, or a carbon fiber cloth 6 is laminated thereon to form a composite base material laminate, which is then subjected to compression pressure, for example. 3-4Kg/cm 2 , compression time (30-60 minutes for cold pressure), 50-90 seconds for hot pressure,
After cold pressing or hot pressing at a temperature of 100 to 105°C to form a composite base material 9, adhesive 3 is further applied onto this composite base material 9, decorative veneer 2 is laminated, and cold or hot pressing is performed. Alternatively, before subjecting the composite base material laminate 9 to cold pressure or hot pressure treatment, an adhesive 3 and a decorative veneer 2 are further laminated to form a natural precious wood composite board laminate as a whole, which is then subjected to, for example, a pressing pressure of 3~ 4Kg/
cm 2 , pressing time (30 minutes to 60 minutes for cold pressing), (50 to 90 seconds for hot pressing), and temperature 100 to 105°C. Manufactured by cold pressing or hot pressing. The natural wood composite board of the present invention manufactured as described above is particularly excellent in that it can prevent warping and knotting, but the prevention of warping and knotting was examined over time. The results are described below. The following laminated materials were used. Γ Use Nara Block 0.3/m thick as decorative veneer Γ Use 4m/m thick natural cork board as cork board Γ Use 0.2 m/m thick cross-shaped glass fiber Γ Adhesive: KR137 (water-based vinyl) Urethane type) The following laminates A to C were prepared as test pieces. A uneven board/KR137/glass fiber/
KR137/Cork board B Narrow board/KR137/Cork board/KR137/
Glass fiber C uneven board/KR137/glass fiber/
KR137/cork board/KR137/glass fiber The bonding conditions were a pressure of 4 g/m 2 , a temperature of room temperature (cold pressure), and a time of 60 minutes. Results: After pressing the laminates A to C above, warping does not occur for several hours after the press is opened, but warping begins to occur as time passes. Although the above-mentioned samples A and B caused the same degree of warping, sample C was able to prevent the occurrence of warpage well. The occurrence of mold was evaluated using the atmospheric dimension method and the underwater immersion method. The novi rate is as follows.

[Table] As is clear from the above results, it is clear that the composite board C of the present invention has an extremely low nodding rate. (Effects of the invention) The natural wood composite board of the invention obtained as described above has good dimensional stability because glass fiber etc. are bonded to both sides of the cork board, and deformation due to moisture absorption and desorption of outside air (knocking, warping). ) can be prevented, and warping does not occur during surface painting, causing no problems during or after construction. In addition, due to the porous nature of cork, it has excellent sound-absorbing effects and cushioning properties, and has excellent properties such as preventing dew condensation and resisting heat and electricity. Therefore, it can be said that it has many uses as a material for flooring, wall, and ceiling materials of buildings, and acoustic-related products.
