Description of the Related Art Wood materials have been conventionally used as building materials for houses, but since they are natural products, the strength of wood of the same tree species may differ depending on the production area and subsequent processing conditions. Therefore, there are problems such as differences in strength and dimensional stability.
From these facts, there is a demand for a wood material which has a constant strength and dimensional stability irrespective of the species and material of the wood, and which has a strength higher than that of conventional wood. Conventionally, a method of impregnating and injecting resin into wood has been performed as a method of strengthening wood, but it is difficult to inject it evenly into the interior, and the equipment is large and costly. Therefore, it is rarely used as a general building material.

It can be performed by pressing. In addition to the rotating roll method,
It can also be carried out by pressing with a planographic plate provided with protrusions. However, roll processing is preferable in terms of equipment. The shape of the protrusions provided on the surface of the roll or the like is not particularly limited as long as it can cut the wood fibers of the single plate, and may be a pyramid, a truncated pyramid, a prism, a cone, or a truncated cone. Although narrow-width plate-shaped protrusions can be used, a pyramidal shape is particularly preferable. FIG. 1 shows an example of the punching device. In the figure, 1 is a veneer, and a large number of recessed holes 5 are formed on the surface of the veneer 1 by passing the veneer between a processing steel roll 2 and a rubber roll 4 each having a number of projections 3 for boring. Formed and the wood fibers cut. 2 and 3 are perspective views showing examples of the protrusions 3. FIG. 2A shows a pyramid-shaped protrusion 3a, FIG. 2B shows a truncated pyramid-shaped protrusion 3b, and FIG. Shows a narrow narrow plate-like projection 3c and a narrow narrow plate-like projection 3d (B) having a flat upper surface.

とよい。The hole is a concave hole formed by press-fitting the protrusion. As shown in FIG. 4, the hole is machined to a depth such that it does not penetrate the veneer 1, and when the adhesive 6 is applied, the cut surface of the hole 5 (inner side wall). ), It is advisable to provide it at a depth such that the adhesive 6, particularly low molecular weight resin liquid, is impregnated and injected into the veneer from the wood material conduit shown in FIG. The depth and width should be such that the wood fiber swells due to water in the agent and restores to the original veneer surface. Although it depends on the material of the wood material, more specifically, the thickness of the plate is 40 to 8
It is advisable to use a recessed hole having a depth of about 0%. However, the holes formed by the protrusions may be through holes reaching the back surface of the veneer as long as the strength of the veneer is not significantly reduced. For example, the tips of the pyramidal protrusions may reach the back surface of the veneer. The smaller the distance between the holes to be provided, the larger the injection amount of the adhesive agent, but it is preferable to provide the holes in a range in which the strength of the veneer does not decrease.

They may be provided alternately as shown in FIG. Although the thickness of the veneer is not particularly limited, it is preferably about 1 to 10 mm, which is usually used for laminated materials, and more preferably about 2 to 4 mm.
The processed veneer that has been perforated as described above is dried if necessary, and then an adhesive is applied by a method such as coating or impregnation, and a required number of laminated materials are formed by means such as heating or pressing. And Laminates can be manufactured as either veneer laminate (LVL) or plywood.

May be applied and impregnated with a low molecular weight resin adhesive, and then laminated and adhered with a high molecular weight resin adhesive. Furthermore, the processed single plate treated with the low molecular weight resin adhesive may be laminated and adhered with an adhesive composed of a low molecular weight resin and a high molecular weight resin to form a laminated material. As the adhesive composed of a low molecular weight resin and a high molecular weight resin in the present invention, an adhesive composed of a low molecular weight phenol resin and a high molecular weight phenol resin can be preferably used. As a low molecular weight phenolic resin,
From the viewpoint of permeation into wood fibers, those having a molecular weight of 400 or less are preferable. A material having a molecular weight of 400 or less and capable of being hardened to give strength to a veneer is used. The high molecular weight phenol resin is not particularly limited as long as it can be used as an adhesive when laminating a single plate, but a phenol resin having a molecular weight of 700 or more is particularly preferable. When the molecular weight is 700 or less, the resin may not be sufficiently impregnated into the wood fiber when mixed with the low molecular weight phenol resin.

It is blended in the range of%. If the amount of the low molecular weight phenolic resin adhesive is 5% or less, the amount of resin impregnated into the veneer may be insufficient and the strength of the veneer may be reduced due to punching.

A single plate 1 is passed between a steel roll 2 and a rubber roll 4 provided with a large number of
A large number of concave holes 5 were opened on one surface of the above to perform fiber cutting. The hole 5 was a pyramid-shaped concave hole having a width of 7 mm, a length of 3 mm and a depth of 3.4 mm, which was formed in a puddle shape on the entire surface of the single plate 1. The veneer was dried with a dryer at 180 ° C. for 8 minutes to finish the water content to 5%.
After that, this single plate was cut into a predetermined size and joined in the width direction and the length direction. The lengthwise joint was cut to form a scarf joint. Next, 100 parts of a phenol resin adhesive PL-S (manufactured by Honen Corporation: resin content 62%) as a high molecular weight resin and 15 parts of a low molecular weight phenol resin (average molecular weight 260: manufactured by Dainippon Ink) as a low molecular weight resin are mixed. The resulting phenol resin adhesive was applied with a coating machine (spreader) at a rate of 20 g / one side. The scarf joint cut veneer coated with adhesive has a scarf joint part in the vertical stacking direction of 15
It was set up so that it was separated by 0 mm. This was temporarily pressed by a cold press, and then thermocompression integrated at 120 ° C. for 10 kg / cm 2 for 25 minutes to obtain a 9-ply veneer laminate (LVL).

れらの性質を有する木質材を得ることができる。INDUSTRIAL APPLICABILITY According to the present invention, since laminated single plates impregnated with resin are laminated, it is possible to obtain a laminated material which is almost uniformly reinforced. Depending on the adhesive used, water resistance, weather resistance and durability can be improved. A laminate can be made. Further, according to the present invention, a wood material having these properties can be obtained by mixing and using a treating agent such as an antiseptic agent, an antifungal agent, an insect repellent agent, a fire retardant agent and a dimension stabilizing treatment agent in the adhesive. .
