Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative board, and more particularly to a decorative board whose surface is provided with a wood grain pattern.

Generally, this type of decorative board has wood grain by bleaching and dyeing wooden veneers, laminating them to form flitches, and slicing the flitches across the lamination direction. However, the process is complicated and there is still a problem that color unevenness is likely to occur. On the other hand, there is a method of printing wood grain on a wooden substrate, such as so-called printed plywood, but this lacks a three-dimensional effect and cannot give a high-class impression. There is also the so-called suminagashi method, but this method involves making grooves in a wooden substrate and pouring the pigment into the grooves, which has the disadvantage that the pigment tends to seep into the wooden substrate and cause bleeding or blurring.

The present invention has been made to solve the above-mentioned drawbacks, and its main purpose is to provide a decorative board whose manufacturing process can be simplified.Other purposes are: To provide a decorative board which is free from bleeding and fading, and which gives a three-dimensional effect and gives a high-class impression.

Embodiments of the present invention will be described below based on the drawings. In the decorative board according to the present invention, a synthetic resin decorative layer (2) is laminated on the surface of a wooden substrate +11, and a transparent synthetic resin layer (8) covers the surface of the decorative layer (2). It is a laminated decorative board, and decorative 1i (2+ is a spring wood part (4) with an embossed number with a wood grain pattern on the surface, and a summer wood colored summer wood filled in the valley part of the spring wood part (4). The first embodiment is shown in Fig. 1. A wooden veneer (7) is laminated on a plywood (6) to form a wooden substrate (1 ) is formed.A transparent sealer (8) is placed on the surface of the wooden substrate t1) to prevent the synthetic resin rill from seeping into the wooden substrate it). Hinyl chloride is applied onto the sealer (8), and a wood grain pattern is embossed on the surface of the semi-gelled Hinyl chloride.
A spring wood portion (4) is formed.

The spring wood portion (4) is transparent and made of vinyl chloride colored in the color of spring wood. The surface of the spring wood part (4) is processed with rainbow bosses to provide unevenness, and chloride chloride colored in the color of summer wood is poured into these valley parts to form the summer wood part (5). . However, since the spring wood part (4) and the sealer (8) are transparent, the wooden substrate (1) can be seen through and a wood texture can be obtained, and the spring wood part (4) is embossed and has unevenness. Because of this, a three-dimensional effect can be obtained. Thus, the spring wood part (4) and the summer wood part (5)
The surface of the decorative layer (2) formed by the above is coated with transparent vinyl chloride to form the top coat layer (3). That is, the summer wood part (5) is formed in the valley part of the spring wood part (4), transparent vinyl chloride nor is applied from above, and the spring wood part (4) is passed through the near furnace.
), summer wood part ([1), and top coat layer (8)] are gelatinized at the same time. Examples of blending pinyluryl chloride used in the spring wood part (4), summer wood part (6), and top coat layer (3) are shown below.

Spring wood part (4) and summer wood part (6) are made of vinyl chloride (Nippon Ceon 121) 100 parts D

It is obtained by blending 0.8 parts of catalyst O and S^.

Figure 2 shows the 20th embodiment, in which a decorative layer (2) and a top coat layer (3) are laminated on a grainless wood veneer (7) such as agathis. The surface of the wooden substrate (1) is coated with a primer. After applying a limer on the wooden substrate (1) and drying it, transparent niluryl chloride was applied to cover the surface of the wooden substrate (1), and it was dried to form a semi-gelled spring wood part ( 4) Form.

The semi-gelled spring wood part (4) is passed through an embossing roll with grooves on its surface to form a wood grain pattern on its surface.

A summer wood portion (5) is formed by pouring hinyl chloride colored in the color of summer wood into the valleys of this embossing, and this is dried to semi-gel, and then a spring wood portion (4) and a summer wood portion are formed. (6
) Transparent vinyl chloride is applied to cover the entire surface of the coating to form a torazu coating layer +81. When the top coat layer (3) is applied relatively thickly, the hyururyl chloride in the top coat layer (3) is semi-gelled. After that, it is molded through a flat plate press, hot rolls, etc. The decorative board formed in this way has a wooden substrate 11 in the spring material part (4).
), the summer wood part (5) shows the summer wood color, leaving the feel of the wood skin, and creating a wood substrate (1) with no wood grain to create a wood grain feel. be.

As described above, the present invention includes a decorative layer of synthetic resin laminated on the surface of a wooden substrate, and a transparent synthetic resin covering the surface of the decorative layer.
It is a decorative board in which a top coat layer of 1 resin is laminated, and the decorative board has a spring wood part with a knee J boss with a wood grain pattern on the surface, and a summer wood that is filled in the valley part on the surface of the spring wood part. Since it is formed with colored summer wood, processes such as decolorization, dyeing, lamination, and slicing are not required, and it has the advantage that it can be manufactured with only simple processes such as coating, drying, and pressing. Since rainbow bosses are formed on the surface of the material, it has the advantage of giving a three-dimensional effect and expressing an appearance similar to wood grain. Furthermore, since the summer wood portion of summer wood color is formed in the valley portion of the spring wood portion, it is possible to provide a decorative board with a clear appearance and an excellent appearance without color bleeding. In addition, it is possible to express wood grain using a wood substrate with no wood grain, and when coloring the spring wood, you can select any color regardless of the other colors of the wood substrate, and when not coloring the spring wood, It is possible to take advantage of the feel of the wood surface of a single wood substrate.
