DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to furniture and doors,
Also, the present invention relates to a method for treating water content-adjusted water and a formalin scavenger for a plate material used alone for a fitting or interior of a building, or a plate material used as a surface material of a flash board.

[0002]

2. Description of the Related Art As this kind of plate material,
Plywood such as wood veneer and plywood, and MDF (compressed integrated board such as chips and fibers) are known. Particularly, in the case of plywood and MDF, an adhesive is used in the manufacturing process, and the surface of the flash board is used. When used as a material or the like, an adhesive is used for fixing each constituent member of the flash board even if no adhesive is used for manufacturing the plate material itself. From this adhesive or surface coating material, until a certain period after production,
Formalin gas (free formaldehyde) is volatilized and released, which is a health and safety problem.

In order to solve such a problem, it is conceivable to apply a formalin scavenger (formalin catcher agent) on the surface of the plate material. However, in particular, the density of MDF or the like is high and the water absorption is poor. In the case of plate material, it is difficult to impregnate the required amount of formalin scavenger, and even if it is possible to impregnate a certain amount of time sufficiently, only a very shallow region from the application surface Since it can only be impregnated, for example, when used as a surface material of a flash board, formalin gas volatilized inside the board captures only the formalin gas that reaches the flash board surface side through the inside of the surface material As a result, it is impossible to efficiently capture the entire amount of formalin gas generated inside the flash board. Shubodo with formalin gas pressure inside is increased, formalin gas is to be discharged to the outside from the cut edge of the small gap and flush board (butt end).

[0004] In addition, there are cases where the water content of the above-mentioned plate material needs to be adjusted before it is used for assembling furniture or a building. When adjusting the water content, simply stacking plate materials coated with water on the surface and leaving them to stand for several hours to several days, particularly in the case of a plate material having a high density such as MDF and poor water absorption as described above. It is extremely difficult to impregnate the required amount evenly.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for treating a board for furniture or building which can solve the above-mentioned conventional problems. Each of the two sides of the furniture or building plate 1 made of a wood veneer, a plywood, a compressed material of chips or fibers, etc.
Alternatively, apply water content adjusting water 2 on one of the surfaces in advance.
Cloth, and apply the water content adjusting water 2 to the two plate materials 1.
It is characterized in that high-frequency heating is performed while applying pressure by the high-frequency hot press 3 in a state of being superposed on each other such that the surfaces facing each other face the plate material .

In carrying out the above-mentioned method of the present invention, when the treatment purpose is the impregnation of a formalin scavenger, the water-containing solution is used.
An aqueous solution of a formalin scavenger is used instead of the rate adjusting water .

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment in which the method of the present invention is used for impregnating a formalin scavenger will be described below with reference to the accompanying drawings. As shown in FIG. 1, plywood such as wood veneer, veneer, etc. An aqueous solution of a formalin scavenger (for example, a formalin catcher manufactured by Miki Riken Kogyo Co., Ltd., Riken Resin FC-18)
-6 (aqueous solution obtained by diluting an undiluted solution of an organic amide-based composite resin) 2 to 10 times) 2, and superimposing two plates 1 so that the formalin scavenger application surfaces are aligned with each other, and a high frequency hot press 3 Is set between the upper and lower bases (electrode boards) 4 and 5, and the applied formalin scavenger aqueous solution of both plates 1 is heated by high frequency to evaporate by the high frequency hot press 3;
By the vapor pressure, the formalin scavenger and moisture are removed from both plates 1
Infiltrate the entire interior of the As a result, both plate materials 1 are impregnated with the formalin scavenger in the entire area at the same time, and at the same time, the water content of both plate materials 1 is adjusted (the water content is increased to an appropriate level).

[0008] The plate material 1 treated as described above can be used as it is for the main body and door of furniture, the interior of a building, etc., but on the opposite side to the surface coated with the formalin scavenger,
It is desirable that a synthetic resin sheet having no air permeability, such as vinyl chloride, be adhered or painted, and used so that the surface coated with the formalin scavenger is on the back side.

FIG. 2 shows a flash board 7 constituted by sandwiching a paper honeycomb 6 between two plate materials 1 processed as described above. Also in this case, the surface of the plate 1 coated with the formalin scavenger is used so as to face the paper honeycomb 6, and a non-permeable air-permeable synthetic resin sheet 8 such as vinyl chloride is attached to the surface of both plate 1. Or it is desirable to use it after painting. Of course, the paper honeycomb 6 can also be impregnated with a formalin scavenger. In addition, the flash board 7 shown in FIG.
Is bent along the chamfered surface of the peripheral frame member 9 disposed around the paper honeycomb 6 to cover the peripheral frame member 9.

In the above embodiment, the aqueous solution 2 of the formalin scavenger is used as the treatment liquid. However, if the purpose is merely to adjust the water content, the aqueous solution 2 of the formalin scavenger in the above embodiment is used instead. Just use water. In any case, it is desirable to apply the processing liquid to each of the two opposite surfaces of the plate 1, but in some cases, the processing liquid may be applied to only one of the two surfaces of the plate 1. .

[0011]

According to the method for treating a board for furniture or building according to the present invention which can be carried out as described above, two sheets of board (wood veneer, plywood, chip or fiber compression integrated material (MD)
F) etc.) Each one side, or any one side
Water for water content adjustment or aqueous solution of formalin scavenger
It is applied in advance and the two plates are treated with water for adjusting the water content or
Surface coated with formalin scavenger aqueous solution
Since high-frequency heating is performed while applying pressure by a high-frequency hot press in a state of being superposed on each other so as to face each other , the processing liquid is disposed in the center between the upper and lower platens (electrode plates) of the high-frequency hot press, and The processing liquid can be highly efficiently heated and evaporated by high frequency heating. The two plate materials can be simultaneously processed. The processing liquid subjected to high frequency heating and evaporation can be surely impregnated into the inside of the two plate materials on both sides by the vapor pressure. Water content adjustment water throughout the interior
Alternatively, a plate material uniformly impregnated with an aqueous solution of a formalin scavenger can be efficiently and easily produced in a very short time.

[0012]

[0013] In particular, according to the method of the second aspect, the aqueous solution of the formalin scavenger can be subjected to high frequency heating to forcibly impregnate the interior of the plate with moisture together with the formalin scavenger by vapor pressure. There is an advantage that conventional water content adjustment and formalin scavenger impregnation can be performed simultaneously and efficiently.
