For example, in FIG. 1, a tree is sawn into square lumber, and the edge of the tree is cut into a square plate. This embodiment is 10 cm × 10 cm
It is a square plate of about 5 mm. Wood piece 1 of this square board
Has the drawback that it rots or burns as it is. In addition, the presence of conduits, temporary conduits, and the like that send moisture to the leaves, and gaps between cells, causes the wood to have a crazy property and a property of absorbing moisture. The tree constituting the wood piece 1 is not particularly limited, and softwood and hardwood can be used. Here, in the case of a cedar material or the like actually used, if the thickness is about 5 mm, there is also a problem that it is easily broken. Depending on the method of cutting the tree, a piece of wood 1 such as a wood opening pattern (a in FIG. 7), a grain pattern (b in FIG. 7), a straight grain pattern (c in FIG. 7) can be obtained. In addition, any one of the wood patterns 1 may be selected.

Pour the resin liquid 3 in the tank 2 into the tank 2
Is immersed (FIG. 2). In the case where the wood product 6 as a product is required to have transparency, the resin solution 3 may be a resin solution of an epoxy resin (used in the present embodiment), an acrylic resin, a non-yellowing polyurethane, a polycarbonate, or a solvent of a butyral resin. A solution or the like is used. When the wooden article 6 does not require transparency, a phenol resin, an unsaturated polyester resin, an allyl resin, or the like is used as the resin liquid 3. The resin liquid 3 is selected in consideration of the hardness, elastic modulus, transparency, various mechanical strengths and the like when it becomes a cured product. The epoxy resin liquid used in the present embodiment is a solvent (here, toluene)
And the viscosity is reduced to 30 centipoise (hereinafter "cp").
) To 100 c.p. Initially, about 5000c.
Although the epoxy resin liquid of p. was used, it was difficult to impregnate the wood piece 1. By using the epoxy resin liquid having the above viscosity, the fluidity is increased and the wood product 1 is easily penetrated, and a desired wood product 6 is obtained.

Place in a. Then, the lid 4b is closed, and vacuum suction is performed from the nozzle 41 using a vacuum device (not shown) (FIG. 3).
Arrow), and the inside of the sealed container 4 is depressurized. Predetermined time,
The air contained in the wood chip 1 and the resin liquid 3 is degassed under reduced pressure.

と、エポキシ樹脂の硬化反応が進むからである。[0011] The degree of vacuum in the sealed container 4 is 400 mmHg vac ~
It is in the range of 700 mmHg vac. If the pressure is smaller than 400 mmHg vac, the effect of the decompression treatment can hardly be expected.
This is because if the degree of vacuum exceeds 0 mmHg vac, a large-scale vacuum device is required. Another reason is that in the manufacture of the processed piece of wood of the present invention, a product of sufficient quality is obtained in the range of 400 mmHg vac to 700 mmHg vac. The inside of the sealed container 4 is maintained at this degree of vacuum for a predetermined time. By reducing the pressure in the closed container 4, the air present in the wooden piece 1 is extracted. The thickness of the wooden piece 1 is about 5 mm to 100 mm and the wooden piece 1
Has a large specific surface area, so that air is smoothly extracted.
The air present in the wood pieces 1 is released as bubbles 5 into the resin liquid 3 and is removed by vacuum suction. Closed container 4
The longer the time during which the inside is kept under reduced pressure, the better, but the total air release amount in the wood piece 1 with respect to the time becomes a horizontal bi-state with the passage of time as shown by a logarithmic curve. Initially, the air emission is high, but thereafter the air emission does not increase significantly over time. In this embodiment, the degree of vacuum in the sealed container 4 is set to about 500 mmHg vac, and the vacuum is applied for about 10 minutes (10 minutes to 20 minutes). If the time is longer than 10 minutes, the curing reaction of the epoxy resin proceeds.

し、該樹脂液3中から木片1を取り出す。As described above, after performing the decompression treatment for a predetermined time while the wood piece 1 is immersed in the resin liquid 3, the vacuum suction by the vacuum device is stopped, the inside of the closed container 4 is released to the atmosphere, and the pressure is reduced to normal pressure for a predetermined time. Leave (Fig. 4). The wood piece 1 is still immersed in the resin liquid 3, and the resin liquid 3 is impregnated and penetrates into voids in the wood piece 1 where air is removed. The voids inside the wood pieces are impregnated with the resin liquid 3 until it is close to 100%. Here, the resin is impregnated into the wood piece 1 under normal pressure. However, even if the pressurized air is switched from the compressed air supply source (not shown) into the closed container 4 by using the nozzle 41 to perform the pressurizing process. Good. In the pressurized state, the wood chip 1 can be impregnated with the resin liquid 3 more quickly and more reliably, which is preferable. After a predetermined period of time, the wood chip 1 is sufficiently impregnated with the resin liquid 3, the lid 4 b of the closed container 4 is opened, the tank 2 is taken out, and the wood chip 1 is taken out of the resin liquid 3.

The pieces of wood 1 are arranged on a sheet so as not to be adhered one by one, and the resin liquid 3 in the piece of wood 1 is cured. Of course, it is also possible to use a heating device or the like instead. By performing such a treatment, a desired wood product 6 obtained by curing the resin liquid 3 impregnated in the wood piece 1 is obtained.

Tiles made by firing clay, such as ceramic tiles, tend to contain moisture inside, and in cold regions, etc., freezing and expansion of moisture causes delamination and destruction. However, in the woody product 6 and the woody tile P of the present invention, the voids of the wood piece 1 are almost completely filled with the resin, and the structure is such that moisture is hardly penetrated. In fact, in a freezing test performed at the Mie Prefectural Chemical Technology Promotion Center Forestry Technology Center, woody products 6 of the present invention immersed in water for 24 hours and
The mixture was left in a freezing room at about 100 hours for about 100 hours and then in a freezing room at minus 85 ° C. for 20 hours to observe the progress. No abnormalities such as delamination were observed. Further, as is clear from the performance test results, the woody product 6 and the woody tile P of the present invention are impregnated with the resin liquid 3 and hardened so that there is no gap into the wood piece 1 so that the wood is messed up. Eliminates the difficulties of absorbing properties and moisture.

せることが可能になっている。In the above-mentioned publication (JP-A-4-20652), a protective layer is formed by impregnating a dimensional stabilizing resin as a first step and coating a resin for enhancing waterproofness as a second step. . Since the coating is performed on the entire surface, there is a problem that if the protective layer is broken, the waterproofness is reduced. In the present invention, the same resin liquid is hardened both inside and outside the wood piece, and no protective layer is required. As for the decompression treatment, the technology disclosed in Japanese Patent Application Laid-Open No. Hei 4-20652 has to secure a high degree of vacuum of 30 mmHg, that is, about 730 mmHg vac, whereas in the present invention, 400 mmHg vac to 700 mmHg v
