成するにいたったのである。That is, the present inventors found that the hardness of conventional modified wood materials that have lost their wood feel or material feel is 50 on the Barcol hardness scale.
~60, but when reducing this hardness to 40 or less, the original wood appearance and texture of the wood material is not impaired, and since it is impregnated with synthetic resin, ■
No warping, no twisting, hard to break, ■ Easy to get dirty (
They discovered the new fact that it is possible to impart excellent properties such as improved water resistance and resistance to rot, leading to the completion of this invention.

られる。Examples of synthetic resins that can be impregnated into wood materials include acrylic resins, urethane resins, unsaturated polyester resins, polyol resins (polyvinyl alcohol, polyethylene glycol, etc.), and epoxy resins. They may be used alone or in combination of two or more. Moreover, these synthetic resins can be used together with a solvent if necessary. Examples of the solvent include ketones, dimethylformamide, dimethylacetamide, dimethylsulfoxide, and toluene.

する。The method of impregnating synthetic resin is not immediately limited;
In addition to the normal pressure immersion method, in which the wood material is immersed in a synthetic resin liquid under normal pressure, there is also the reduced pressure immersion method, in which the wood material is immersed in the synthetic resin liquid under reduced pressure, and then immersed under normal pressure or increased pressure. Any method such as a pressure dipping method can be employed, and the method is appropriately selected from among these dipping methods depending on the desired degree of impregnation.

漬を行う。In the case of the normal pressure immersion method, it is necessary to immerse the wood material in the synthetic resin liquid for several hours or more. In addition, immersion under reduced pressure involves placing the wood material in a vacuum pot and reducing the pressure (for example, at 10 Torr or less).
After injecting the synthetic resin liquid into the pot, either return the pressure inside the pot to normal pressure and continue immersion for several hours or more, or pressurize and immerse. I do.
また、含浸操作にあたっては、木質材料をあらかじめよ
く乾燥させておくのが好ましい。Further, in the impregnation operation, it is preferable to thoroughly dry the wood material beforehand.

にするためには、合成樹脂の含浸量が木質材料１００重
量部に対して約５〜５０Ｍ量部であるのが適当である。The amount of synthetic resin impregnated is important because it determines the hardness of the wood material, and it is necessary to determine the amount of impregnation so as to obtain the desired optimum hardness. In this case, in order to preserve the wood-like appearance and texture of the wooden material impregnated with synthetic resin, it is preferable to set the hardness to 40 or less on the Barcoll scale. In order to reduce the hardness to 40 or less, it is appropriate that the amount of synthetic resin impregnated is about 5 to 50 M parts per 100 parts by weight of the wood material.
なお、硬度があまり低くなると、素材感はより向上する

ば浴室、浴槽。Note that if the hardness is too low, the texture of the material will improve, but the strength against warping, twisting, cracking, etc. will be weakened.
In addition, stain resistance, water resistance, and corrosion resistance will also be inferior, so it is necessary to select according to the purpose and place of use.For example, a bathroom or bathtub.
洗面所などの衛生材料に木質材料を使用する場合は、肌

尊重される反面、耐久性のうえから耐水性や耐腐食性が
要求される。When using wood materials for sanitary materials such as washrooms, the wood surface comes into direct contact with the skin, so while the soft wood appearance and texture are respected, water resistance and corrosion resistance are required in order to ensure durability. Ru.
この場合、樹脂含浸した木質材料を水に浸漬したときの
木質材料の含水率は７０％以下となるように樹脂含浸す

当である。If the wood material requires cutting, such as for construction materials such as tight edges and cut edges, it is impregnated with resin before or after the processing. FIG. 1 shows the process of creating a surrounding edge 2 by cutting or the like from a wooden material 1 in the shape of a square prism. In this case, the resin impregnation may be performed on the wooden material 1, or may be applied to the processed (wheat edge 2) impregnation is carried out so that the entire wooden material 1 or the edge 2 is impregnated with the synthetic resin. Alternatively, as shown in Fig. 82, only the surface layer portion of the processed edge 2' may be impregnated with resin to form the resin-impregnated layer 3. In this case, the resin-impregnated layer 3 It is appropriate that the Barcol hardness is 30 or less and the water absorption rate is 60% or less.

ある。Also, Figure 1 and jF! In Fig. 2, wood such as softwood is used, but instead of wood, a modified wood material having a structure as shown in Fig. 3 can be used.
The modified wood material shown in the figure is manufactured by placing the veneer 5.6 impregnated with synthetic resin and the peeling materials 7, 8 on the front and back surfaces of the core material 4 and the end surfaces of the wood as described above, respectively, by gluing or the like. A male seed s9 and a male seed 810 are formed respectively.

むく材７．８を配置したので、むく材のみを用いる場合
に比べて安価に製造できるという利点がある。さらに、
単板５．６等の厚さの薄い部材に合成樹脂を含浸させる
ので、含浸が容易である。In this way, since the resin-impregnated veneer 5.6 and the timber 7.8 are arranged around the core material 4, there is an advantage that the product can be manufactured at a lower cost than when only timber is used. moreover,
Since a thin member such as the veneer 5.6 is impregnated with the synthetic resin, impregnation is easy.
次に実施例をあげてこの発明の改質木質材料を詳細に説

３であった。Example 1: A Japanese cypress wood material was cut into a shape with a tight edge as shown in FIG. Put this in a vacuum cooker and make the inside of the cooker 1
After reducing the exhaust pressure to below 0 torr, the urethane resin liquid was injected, and then the pressure inside the pot was returned to normal pressure, and immersion was continued for a further 10 hours. As a result, the resin was impregnated at a ratio of 47.5 parts by weight per 100 parts by weight of the wood material. The hardness of the obtained modified peripheral edge (Barcol hardness, same hereinafter) is 38.
It was 3.
実施例２： 樹脂の含浸量を３１宙量部にしたほかは実
施例１と同様にして改質廻り縁を得た。Example 2: A modified peripheral edge was obtained in the same manner as in Example 1, except that the amount of resin impregnated was 31 parts.
このものは硬度が３０．２であった。This product had a hardness of 30.2.
比較例： 樹脂の含浸量を５８．４重量部にしたほかは
実施例１と同様にして改質廻り縁を得たゆこのものは硬
度が５５．６であった。Comparative Example: A modified rim was obtained in the same manner as in Example 1 except that the amount of resin impregnated was 58.4 parts by weight, and the hardness was 55.6.

いがないことを意味する。The texture of each of the modified edges obtained in these Examples and Comparative Examples was compared with that of an edge made of the same natural cypress material and not impregnated with resin. The comparison was carried out by a sensory test conducted by 10 panelists. The results are shown in the table below. In the table, "with texture" means that the texture is similar to natural cypress wood, and "without texture" means that there is no texture like natural cypress wood.

ぐれるという効果がある。From the table, it can be seen that the modified surrounding edge of this example does not lose its wood texture and has an excellent taste. Moreover, since this material is impregnated with resin, its properties such as strength are superior to natural cypress wood. [Effects of the Invention] According to this invention, the hardness of the wood material is reduced to 40 or less by impregnating it with synthetic resin. Because of this, the original unpleasant taste and texture of the wood material is not impaired, and by impregnating it with synthetic resin,
It has the effect of improving strength and having excellent stain resistance, water resistance, corrosion resistance, etc.
