However, a hard material having a hard surface cannot be obtained. Damage or cracks. Therefore, in recent years, it has been practiced to laminate a medium density fiberboard (MDF) on both sides of a plywood to form a substrate, and to laminate a veneer on one side of the substrate to form a building material. This is a material in which a medium-density fiberboard is laminated so that it is unlikely to be damaged or cracked by casters even when used as a floor material.

In order to prevent cracks, the medium-density fiberboard only needs to be present on the lower surface side of the veneer, and in the conventional case where the medium-density fiberboard is laminated on both sides of the plywood to form a substrate. Is that the thickness of the building material becomes thicker than necessary,
In addition, there is a problem that the material cost increases. Therefore, it is conceivable to form a substrate by laminating a medium-density fiberboard only on one side of the plywood and form a board by laminating a veneer on the medium-density fiberboard side of the substrate by hot pressing.

To form a plywood. In forming the plywood 1, the veneer constituting the plywood 1 is made absolutely dry, and the thus dried veneer is applied with an adhesive, and the plywood 1 is formed by hot pressing. In this case, the fiber directions of the upper and lower veneers are arranged so as to intersect each other. The plywood 1 in the absolutely dry state thus formed is cured for 5 to 7 days until the heat cools. Next, about 15 g of water is uniformly applied to the cooled plywood 1 per 2 squares, and cured for 3 to 5 days until the moisture is adjusted, so that the water content of the plywood 1 is about 10%. In this way, the water content of the plywood 1 can be made uniform within and between the sheets, and a flat plywood 1 can be obtained by making the water content uniform.
In FIG. 1, the plywood 1 is composed of five veneers 1a, 1b, 1c, 1d,
1e, an example is shown. In one example,
Veneer 1a is a 1.57 mm parallel veneer, veneer 1b is 2.4.
mm veneer, veneer 1c is a 1.57 mm parallel veneer, veneer 1d is a 2.4 mm veneer, veneer 1e is a 1.57 mm parallel veneer. Each thickness is 9.1 mm, but is not necessarily limited to this.

Here, by omitting the humidity control step when manufacturing the medium density fiberboard 2, the medium density fiberboard 2 is made to be in a completely dry state. The thickness of the formed medium-density fiberboard 2 is, for example, 2.7 mm, but is not necessarily limited thereto.

An adhesive such as a vinyl urethane adhesive is applied and pressed by a cold press to form the substrate 3. Here, the mid-density fiberboard 2 in the absolutely dry state expands by absorbing moisture, and the plywood 1 having a water content of about 10% is released by moisture and contracts, as shown in FIG.
As a whole, the warped substrate 3 is formed such that the surface on the medium density fiberboard 2 side becomes a mountain warp. Here, if an aqueous vinyl urethane adhesive is used as the adhesive, it can be bonded by a cordle press, and the adhesiveness (water resistance) is also excellent.

である。Next, as shown in FIG. 4, a veneer plate is placed on the medium-density fiber board 2 obtained by warping the surface on the side of the medium-density fiber board 2 obtained as described above so as to be curved. 4 and a paint is applied to the surface of the veneer 4 as shown in FIG. In FIG. 5, reference numeral 6 denotes a paint layer. The veneer plate 5 has a water content higher than that of the substrate 3. As an example, a veneer veneer 5 of 0.25 mm thickness and a water content of 30% can be used, but is not limited thereto. A veneer 5 having a higher moisture content than the above-mentioned substrate 3 is bonded onto the medium-density fiberboard 2 of the above-mentioned substrate 3. As an example of the bonding conditions in this case, a mixture of an SBR resin and a melamine resin is used as the adhesive, and the application amount is 8 g / scale 2 and the pressing pressure is 7 k.

The length is 6 meters.) The maximum warpage is 20m
In the case of m, after the veneers 4 are stacked and hot-pressed, the maximum warpage shown in FIG. 2 is 5 mm, and the warpage becomes zero due to shrinkage of the paint due to surface coating.

The presence of the medium-density fiberboard 2 on the lower surface of the caster prevents the caster from rolling,
In addition, since cracks do not occur and warpage does not occur, it is particularly useful when used as a floor material or the like. In addition, when manufacturing the plywood 1, it is preferable to use a sapwood as a veneer used for the back surface. Here, when the wood is sliced, the material obtained from the central part of the wood is called the core material, and the material obtained from the peripheral part of the wood is called the sapwood (Since the sapwood is obtained from the peripheral part of the wood, It is composed of cells that are growing and the tissue is more porous than the core material, so the water supply is higher than that of the core material. And the other four veneers use a core material. Then, as described above, the plywood 1
After forming the plywood, the non-sintered medium-density fiberboard 2 may be laminated and integrated by cold pressing on one side of the plywood 1 which is not the side material.
