Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The disclosed technology belongs to a technical field in which unit materials made of wood are surface-bonded to each other with an adhesive.

[0002]

2. Description of the Related Art As is well known, in Japan where the terrain conditions are close to the coastline where many mountainous forest areas are intricately complex, there are only a limited number of plain areas that can be effectively used for buildings, etc. ， Regardless of the rural area, the buildings are built densely, and in the residential area, among others, houses are intensively built through complicated roads such as mazes.

[0003] In addition, although there is an intensive building type house such as an apartment or a condominium in the house,
Houses such as detached houses are standard, including apartments.

[0004] Since wood and the like supplied under the natural and seasonal conditions of our country are relatively abundant as materials, it is standard that the building is made of wood. .

As a material, a plywood 3 such as a veneer plate in which wood unit materials 1, 1 ... As shown in FIG. 1 are pressure-bonded to each other with an adhesive 2 in between, or in FIG. As shown, unit materials 1 ′, 1 ′, etc. are laminated with an adhesive agent 2 between the laminated materials 3
'Or as shown in Fig. 3, the unit materials 1''and1''as pillar materials are laminated materials 3''via the adhesive 2 are widely used for factory production. It is planned and used.

The adhesive 2 used for surface-bonding these integrated materials 3, 3 ', 3 "to the unit materials 1, 1', 1" is overwhelmingly advantageous in terms of productivity and cost. A large amount of chemical adhesives are used.

For example, vinyl acetate or cornstarch is used as a material for the adhesive. Since cornstarch is a protein, mold tends to be generated over time,
Therefore, in most cases, formaldehyde (formalin in the case of a 30% aqueous solution) is used as an antifungal agent also as a binder.

[0008]

However, the formaldehyde and formalin have the disadvantage that they contaminate the air during use, including the manufacturing process, pollute the surrounding environment, and cause allergies.

[0009] Since vinyl acetate is a chemical material, a large amount of black smoke is generated when it is scrapped due to demolition at the time of renovation or in the event of a recent major disaster, and when it is incinerated such as open burning. Etc., and harmful gases such as dioxin are generated when incinerated at 1000 ° C or higher,
There was a drawback that caused air pollution.

In particular, in the case of small-scale incineration, there are no serious obstacles such as air pollution and there are no legal restrictions.
In the event of a large amount of incineration in the event of a disaster, it caused unsafe pollution to the fire station staff and waste disposal companies who incinerate due to the generation of dioxin, etc.

It is becoming clear that this is a harmful effect of not breaking down the wood itself as a unit material, and is a social obstacle that cannot be ignored due to the adhesive.

[0012] In order to cope with this, an alternative means capable of supplying a large quantity and stably has not been developed in terms of cost and manufacturing process, and there are many requests expecting this. , What is happening.
