Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a building board formed using a board material formed by pressure-molding a large number of thin wood pieces together with an adhesive as a base material, and a method for manufacturing the same.

[Prior Art] In recent years, with the diversification of building materials, there has been a demand for materials with a novel appearance. In particular, there is a need for building boards that retain the warmth and gentleness of wood and have an appearance that can be adapted to modern living spaces. As a building board that satisfies these requirements, the present applicant has previously filed Japanese Patent Application No. 62-2 [1]
The application disclosed in No. 756 was filed. This building board was formed by applying adhesive to a thin piece of wood, pressing it into blocks to form 79 blocks, and slicing these 7 blocks. This product met the above requirements to some extent, but the color change was poor. The present applicant had previously filed a patent application in 1983 for a product with color change.
The application disclosed in No. 326311 was filed. Such items are made by dyeing thin pieces of wood in a desired color, applying adhesive and pressing into blocks to form 79 pieces, and then gluing multiple pieces of 79 pieces of different colors together to create a composite 7 piece piece. A building board is formed by slicing this composite 7-rich material. The building board A' obtained by this method was dotted with dark colored areas A and light colored areas, as shown in FIGS. 5(a) and 5(b).

[Problems to be Solved by the Invention] Although the above-mentioned conventional products do not change color easily, the color boundaries are clear, so they tend not to be suitable as interior materials that require a calm atmosphere. Ta.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a building board with blurred horizontal and calm appearance without clear color boundaries, and a method for manufacturing the same. .

[Means for Solving the Problems 1] In order to achieve the above-mentioned object, the building board of the present invention has a board material 2 formed by pressure-forming a large number of thin wood pieces 1 together with an adhesive, and partially imparts a blurred horizontal pattern 3 to the surface of the board material 2. The manufacturing method of the building board of the present invention involves applying a coloring agent such as a dye to the surface of the board material 2, which is formed by pressure-forming a large number of thin wood pieces 1 together with an adhesive. Apply it so that
It is characterized in that the coloring agent is then fixed by steaming.

[Function] As described above, it is possible to obtain a building board whose surface is colored in a shading horizontal pattern 3, and it can be used as a building board with a subdued appearance.

[Example 1 As for the plate material 2, the present applicant first applied for patent application No. 62-2] 175
The one filed as No. 6 can be used. As shown in FIG. 1, a thin piece of wood 1 obtained by slicing wood is dyed, then dried, an adhesive is applied to the thin piece of wood 1, and then the thin piece of wood 1 is pressed and formed using a press device 3. Seven rich pieces 4 are formed, and the plate material 2 is obtained by slicing the seven rich pieces 4 with a slicing blade 5. The wood flakes 1 have a thickness of 0.05'-0.80 mm (preferably 0.10-0.50 mm), an area of 6-400 mm, an aspect ratio of 0.4-7.0 (preferably is 0.8 to 3°0).These wood thin pieces 1 may be rounded, and as long as the above shape is 60% or more, dimensions other than the above may be included. For example, the first dyeing process
As shown in the figure, the dyeing process is carried out by immersing the inner piece n8 containing the wood thin piece 1 in the dyeing liquid 7 in the dyeing tank 6. The adhesive is applied to the wood slices by spraying or kneading. The type of adhesive is not particularly limited as long as it has a hardness that allows slicing after bonding, but the following adhesives are considered suitable.For example, urethane adhesive, urethane emulsion adhesive, soft polyester resin, acetic acid There are vinyl adhesives, etc. Pressure forming of the thin wood piece 1 coated with adhesive is performed in a press device 3, and as shown in FIG. The pressure applied by the pressing device 3 is sufficient to crush the wood flakes 1 along the press surface, and
-25 Kg/am2 (preferably 7-14 K17c
m2). 7-rich 4 pressed and formed by press device 3
is sliced by the slicing blade 5 to create a veneer-like plate material 2
is formed.

A building board A is formed by coloring the surface of this board material 2 and providing a shading horizontal pattern 3. In other words, dyes are used as colorants, and dark and light dyes are applied as appropriate.
The dye was fixed by steaming. By doing this, as shown in FIG. 2, a blurred area with an unclear boundary between the dark-colored area A and the light-colored area A was obtained. Methods for applying this dye include methods such as brushing, a sponge roll coater, a Gradigi 1-inch roll coater, and a spray coater. The building board A with the bulge horizontal pattern 3 is pasted on a substrate such as plywood, the surface is coated with paint such as 177-paint, and the board is used for flooring, etc.

Other examples include: 7 riches 4 are formed in the same manner as above, but when dyeing, the dye is changed to form 7 riches 4 of a plurality of colors.

As shown in FIG. 3, 11 of these 7 riches 4 of different colors are arranged to form a composite 7 rich 11, and this composite 7 rich 11 is sliced with the slicing blade 5 to obtain the dark colored part. A plate material 2 is obtained which is dotted with light-colored partial openings. To form a gaping horizontal pattern 3 on this board material 2, for example, apply a dye of the same type as the dark color to the boundary between the dark part A and the light part B, and then steam the dye. Make it stick. Another method is to apply the dye to the entire board 2 and fix the dye by steaming. In either case! As shown in Figure #4, a blurred area with an unclear boundary existed between the dark-colored area A and the light-colored area A. The building board A with the blurred horizontal pattern 3 is pasted on a substrate such as plywood, the surface of which is coated with a paint such as clear paint, and used as wall material.

Next, a specific example of the building board of the present invention will be introduced.
