ある。2. Description of the Related Art In recent years, a large amount of lauan plywood has been used as a floor base material for which the amount of use has increased significantly.
This is closely related to the fact that raw raw wood growing in the rainforest region has been supplied more stably and cheaply compared to other materials even if there is a slight wave until recently.

た。[0006] For example, in a particle board, dimensional stability against moisture, bending strength, easiness of processing, lightness, etc. are far below those of Lauan plywood. In addition, MDF, which has been attracting attention recently, is far superior to Lauan plywood in terms of surface smoothness, but it is expensive and has very poor dimensional stability against moisture, so it has established itself as a substitute material for Lauan plywood. It was still insufficient to do so.
In addition, since softwood plywood has the same structure as Lauan plywood, it is excellent in dimensional stability, bending strength, ease of processing, and the stability of supply because it can be planted, and it is a material relatively close to Lauan plywood. However, most coniferous trees have many nodes and the difference in hardness and softness (fall wood part and spring wood part) on the surface is very inferior in flatness smoothness. It was difficult to bond a board or a decorative paper.

Since it is very difficult to use DF, softwood plywood or the like alone instead of Lauan plywood, attempts have been made to use the above materials in combination. For example, MDF was heat-pressure-bonded to the surface of a softwood plywood or a thin particle board via an adhesive. However, in all cases, the four laps were warped upward after heat-pressing and tended to be just like a bowl. In order to use such a composite plate warped like a bowl as a floor board, if the four edges are actually processed and nailed or glued, the butt surface will rise and become uneven, and the makeup of the raised part will Has a defect that it is worn away due to abrasion and the base material is exposed only in that part, which makes it very unsightly.

う欠点もあった。Since the hot-pressing method warps like a bowl, it has been attempted to manufacture a composite plate by the cold-pressing method, but the adhesive used for the cold-pressing method is expensive, and moreover, to bond softwood by the cold-pressing method. Since a large amount of adhesive is required, the price of the composite plate becomes higher and higher, and there is a drawback that the adhesive protrudes from the edges. Further, the cold pressing method is much worse than the hot pressing method from the viewpoint of productivity, and there is a drawback in that when the surface of the manufactured composite plate is coated with the top coating material and dried, it also warps into a bowl shape.

Reference numeral 1 is an MDF, and the thickness is preferably about 2 to 3 mm from the economical point of view, but the thickness is not limited to this. Further, as a raw material for MDF, there are a material using a softwood material, a material using a hardwood material, and a material using a mixture thereof, but any material may be used in the present invention. In addition, MDF includes melamine type, phenol type, urea type, etc., but when used as a floor base plate, melamine type or phenol type MDF excellent in water resistance and heat resistance is preferable. Of course, when it is used in a place where water resistance is not so required, such as a wall board or a ceiling board, a urea type MDF may be used. The MDF is previously dried in a hot platen or a drying oven so that the water content is preferably 3% or less. M
Even if the water content of DF exceeds 3%, there is a difference between the water content of MDF and the water content of softwood plywood, etc., but 6%
It is more preferable if there is the above difference. However, from the viewpoint of productivity, it is better to make it 3% or less. because,
This is because it is easier to control in terms of production when the water content of MDF is 3% or less, in other words, when it is close to an absolutely dry state. 2, 3 and 4 are coniferous veneers, and these veneers show a state in which the fiber directions are orthogonal to each other.
The present invention is not limited to this. For example, the fiber directions of the softwood veneer may be the same.

The MDF 1 and the three softwood veneers 2, 3 and 4 may be combined into one composite sheet with an adhesive. When laminated and hot pressed, the water content of the softwood veneer is preferably almost air-dried even if there is some difference depending on the adhesive used. Here, the air-dry state refers to 6 to 15% although there are regional differences. This water content is also not limited to the air-dried state, but varies depending on the water content of MDF. However, it goes without saying that the air-dry state is preferable in view of productivity. In addition, the heat and pressure conditions are a temperature of 110 ° C to 130 ° C and a pressure of 6 to 10 kg /
cm 2 , time is about 3 to 10 minutes, which is the same as or close to the conventional hot pressing condition during plywood production.

It is desirable to keep the water content of softwood plywood in an air-dried state. By doing so, the composite plate produced does not warp in a bowl shape, but is in a substantially smooth state or in a slightly inverted bowl shape.

Of course, after the sealing coating material is applied and dried, the top coating material may be applied and dried, or both may be simultaneously dried. By doing so, the top coating material on the front surface and the sealing coating material on the back surface are balanced, and warping is less likely to occur. In FIGS. 3 and 4, the decorative sheet 5 is attached to the surface before drying the MDF, and in this case also, the water content of the decorative sheet-attached MDF is preferably 3
It is dried so that it is less than or equal to%. When the decorative sheet 5 is pasted on the surface in this way, there is an advantage that the plane tensile strength becomes larger than that when the decorative sheet 5 is pasted. This is considered to be because when the decorative sheet 5 is pasted on the surface of the MDF after drying, the surface of the MDF is slightly deteriorated by heat. The top coating material is applied to the front surface of the composite plate thus manufactured, and the sealing coating material is applied to the back surface thereof and dried. Examples of the sealing paint used in the present invention include phenol resin, polyurethane resin, polyester resin and the like. Further, if necessary, an antiseptic agent or an antifungal agent may be added to the sealing paint to impart an antiseptic or antifungal effect to the back surface of the decorative composite board. The sealing paint may be applied to the mouth of the decorative composite board.
