Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for manufacturing a wooden veneer decorative board used for flooring and the like.

[Background technology] Conventionally, in manufacturing wood veneer decorative boards such as flooring materials, the veneer is attached to the surface of the base material with an adhesive, and the surface of the veneer is colored using a reverse roll coater or the like. Therefore, the surface of the veneer is painted and the wood grain is brought out at the same time, but in the case of thin veneers, it is difficult to bring out the wood grain because the adhesive oozes out, and the entire surface is darkly colored. There was a deep breath.

[Purpose of the invention]

The present invention has been made in view of the above points, and it is an object of the present invention to provide a method for producing a decorative wood veneer board that allows for beautiful wood graining and a thin coating on the surface. This is the purpose.

[Disclosure 1 of the Invention In other words, the method for manufacturing a wood veneer decorative board of the present invention involves loading a ring-hole material veneer 4 having ring-hole portions 3 on the surface of a base material 1 via a colored adhesive 2. The vf characteristic is that the colored adhesive 2 bleeds onto the surface through the ring hole 3 of the veneer 4, and the adhesive 4 that bleeds onto the surface of the veneer 4 hardens along the wood grain and forms an adhesive layer. 5, the above object was achieved.

The present invention will be described below in detail based on Examples 6. Post-coloring material 2
The adhesive 2 is made by adding and mixing colored pigments into the adhesive, and the adhesive 2 is, for example, urea υ (greasy adhesive,
7 er/-lease adhesive, vinyl acetate 111111 adhesive, etc. can be used. The colored adhesive 2 is adjusted to have an appropriate viscosity in order to cause it to bleed onto the surface of the ring-hole veneer 4', as will be described later. The R flower material is one in which the main conduits are lined up along the annual ring when looking at the wood end surface, and for example, oak wood, zelkova wood, etc. can be used.

Therefore, the ring hole portion 3 is formed in the ring hole material veneer 4 in the shape of wood grain. When manufacturing decorative board Ae,
As shown in FIG. 1, a veneer 4 is placed on the surface of a base material 1 with the colored adhesive 2 interposed therebetween. At that time, it is preferable to press the veneer 4 to the base material 1 side using a press, a roll, etc. The adhesive 2 is led to the surface side through the ring hole 3 of the veneer 4, as shown in FIG. As shown, a colored adhesive layer 5 is formed on the surface of the ring-hole material veneer 4 along the ring-hole portion 3 (wood grain) of the veneer 4.Next, the surface of this veneer 4 is polished. After that, the surface of the veneer 4 is colored with paint 6. The paint 6 is the same color as the adhesive 2 above□
It is possible to use a type of adhesive material or a material of a different color from the adhesive material 2, and the coating method is not limited, and can be applied by a reverse roll coater or by spraying.

Therefore, by bleeding the adhesive 2° onto the surface of the veneer 4 and forming the adhesive layer 5 along the grain of the veneer 4, the grain of the wood can be clearly defined. By making the veneer 4 surface so thin that it can be seen from the surface side, the surface of the veneer 4 can be seen through the thinly colored paint 6 without any force, and the colored adhesive layer 5 forms the wood grain. At the same time, the entire surface is dark (it does not become dark), and the adhesive material 2 is a paint 6 of a different color.
For example, by using colored adhesive 2 in brown and paint 6 in red, blue, etc., the spring wood part can be colored in a color different from the wood grain part (autumn wood part). This makes it possible to obtain a multi-colored wooden veneer decorative board A.

Further, since the adhesive layer 5 is formed on the surface, a flooring material having good abrasion resistance in the wood grain portion and hard to wear out in the wood grain portion can be obtained. Furthermore, even if low-grade materials are used for the base material 1 and the veneer 4, the wood grain can be exposed on the front shoulder, making it possible to reduce material costs and reduce the defective rate in the process.

In addition, in FIG. 3, a decorative veneer 4 is pasted on the front side of the base material 1, and a soundproof sheet 7 is pasted on the back side of the base material 1 to form a soundproof flooring material B. That is, the conventional thickness 12
If plywood flooring of mm or 15 mm was installed directly on the joists on the second floor, the transmission of sound to the lower floors would be a major problem, and if soundproof mats or sheets were used, it would be expensive. As a substitute for plywood, Chifububoard (Startskud) was used as the base material 1, and 1. A neoprene rubber foam sheet 7 of Oa+m to 2.0 mm is adhered. This product has the advantage of having a great soundproofing effect and being inexpensive.
have.

[Effects of the Invention] As described above, the present invention includes stacking a ring-hole material veneer having a ring hole on the surface of a base material via a colored adhesive, and applying the colored adhesive to the ring-hole portion of the veneer. I let it bleed to the surface through the
A colored adhesive layer is formed on the surface of the veneer in a woodgrain-like pattern, allowing for beautiful wood graining.
Furthermore, by using a thin paint as the paint for coloring the surface, a decorative board with a lightly colored surface can be obtained.
