Abstract

PURPOSE:To improve fire proofing performance by constituting a furniture in use of a laminate material obtained such that a plurality of incombustible woody veneers are laminated which is filled or adhered with an incombustible inorganic compound. CONSTITUTION:An incombustible treatment is conducted by sufficiently soak-impregnating woody veneers in the water solution of water soluble inorganic salt. First, it is subjected to soak-impregnation in water solution of the first liquid, for example, such as MgCl2 or the like and, second, it is immersed in the water solution of second liquid, for example, such as Na2CO3 that produces a water insoluble incombustible inorganic compound in reaction with the first liquid. The incombustible inorganic compound is blended at 33wt.% or more with respect to the woody veneer. After the incombustible woody veneer applied with an adhesive substance is laminated in plural-sheets relation, they are press-adhered by the use of a press clamping device such as hot press, cold press and the like. At the time when a plurality of incombustible woody veneers are laminated, it is preferable that the fiber directions thereof are allowed to intersect each other arbitrarily and also preferable that all of the fiber directions are allowed to lie in the same direction. By employing the thus obtained laminated material, a decorative laminated board is obtained that is adhered with a decorative sheet substance in its entire surface. The decorative laminated board is used for the top board, bottom board, side boards, rear board, and the like of a furniture main body.

Description

[Detailed description of the invention] <Industrial application field> TECHNICAL FIELD The present invention relates to furniture with excellent fireproof performance.

<Prior art> Furniture such as storage furniture and kitchen furniture used in general households are difficult to process, design, and feel. In order to satisfy requirements such as weight and price, at least the main body is usually made of wood.

By the way, in the construction of houses, from the perspective of fire prevention, restrictions are placed on the structure and materials used under the Building Standards Act.
Interior decoration restrictions are imposed on indoor rooms, and wall materials are required to be made of non-combustible or semi-non-combustible materials.

However, if a fire actually breaks out indoors, the furniture installed in the room and the items stored inside the furniture will ignite, intensifying the fire, and the restrictions under the Building Standards Act alone will not be sufficient for fire prevention purposes. There was a problem with not being able to achieve it. Ignition of furniture, etc. is the biggest cause of fire spread.

<Problems to be Solved by the Invention> Therefore, an object of the present invention is to provide furniture whose main body is basically made of wood but which has excellent fireproof performance.

Means for Solving the Problem> The above problem is achieved by attaching multiple non-combustible wood veneers, each of which has a non-combustible inorganic compound filled or adhered to the inside of the cell pores and/or the inner wall surface, through an adhesive substance. A decorative sheet-like material is applied to the front surface of the substrate, the front and back surfaces, or the entire front surface including the butt edge, using a laminated material that is bonded so that the fiber directions are arbitrarily orthogonal or that the fiber directions are all in the same direction. The problem is solved by furniture characterized in that at least a part of the structural member is made of a decorative board formed by adhesion.

Furniture generally consists of a top plate, bottom plate, side plate, and back plate, and parts such as doors, doors, drawers, shelves, etc. are incorporated as appropriate, and metal fittings such as hinges, handles, rails, and door handles are also incorporated. attached and formed.

At least some of the constituent members of the furniture of the present invention, particularly the decorative board used as the board material of the furniture body, is a noncombustible wood veneer in which the cell pores and/or the inner wall surface are filled or fixed with a noncombustible inorganic compound. The substrate is a laminated material formed by laminating and bonding a plurality of sheets together using an adhesive, and a decorative sheet-like material is adhered to the front surface, front and back surfaces of the substrate, or the entire front surface including the butt edge.

The wood veneer is obtained by cutting logs or flitches of trees such as cedar, pine, toga, cypress, lauan, and capor using a cutting device such as a rotary lace, a half-rotary lace, or a slicer. This wood veneer has many cell pores consisting of wood cells, conduit pores, or thickness pores, and these cell pores are opened on its surface, or numerous cracks are exposed. .

The resulting wood veneer is dried to reduce its moisture content to 7-15%.
adjusted accordingly.

A nonflammable inorganic compound is filled into the voids such as cell pores and conduit pores of the dried wood nest board, or the nonflammable inorganic compound is fixed or adhered in a layer along the inner wall of the cell pore, and then the wood pores are Nonflammability treatment is performed by fixing or adhering the nonflammable inorganic compound to the front and back surfaces of the board. This nonflammability treatment can be performed, for example, by the following steps. That is,
The wood veneer is sufficiently immersed in an aqueous solution of a water-soluble inorganic salt (hereinafter referred to as "first solution") to impregnate it. At this time, it is effective to forcibly accelerate the impregnation treatment by applying reduced pressure or increased pressure. Alternatively, the wood veneer may be brought into a high moisture content state without drying, or after drying, it may be immersed in water or hot water to absorb water to saturate it, and then immersed in the first liquid for diffusion impregnation. You can let me. As the first liquid, MgcQ2

Examples include aqueous solutions such as The immersion treatment of the wooden veneer in the first solution varies depending on the conditions such as the species of wood, the thickness of the board, and the impregnation method, but is generally carried out for about 30 minutes to 6 hours at intervals. By immersing the wooden veneer in the first solution, ions of the solute inorganic salt diffuse into the cell pores of the wooden nesting board.

Next, a dewatering process is performed to remove the excess first liquid. The liquid removal treatment is carried out by means such as centrifugal dehydration or washing with Java or dobuzuke, and by removing the excess first liquid, an excessive amount of non-combustible inorganic compounds is removed from the surface or outer periphery of the wood veneer. This suppresses the formation of the aqueous solution and improves the diffusion and impregnation of the aqueous solution that will be impregnated next. It also prevents nonflammable inorganic compounds from being generated in a free state that is not attached or fixed to the wood veneer.

Next, a compound liquid that reacts with the first liquid to produce a water-insoluble, nonflammable inorganic compound (hereinafter referred to as the "second liquid") is added to and mixed with the wood veneer using a blender, spray, etc. The wood veneer is impregnated with the second liquid by dipping. As in the case of the first liquid, impregnation of the second liquid into the wood veneer can be promoted by reducing or pressurizing the wood veneer. As the second liquid, Na2CO3, H2S

By applying or dipping the second liquid, the second liquid is diffused and impregnated into the cell pores of the wood veneer, and the first and second liquids react in the wood veneer, producing a nonflammable inorganic compound. be done. The nonflammable inorganic compounds produced are magnesium phosphate and calcium phosphate'.

Barium phosphate, aluminum phosphate, magnesium borate, magnesium carbonate, calcium carbonate.

Examples include carunium compounds such as zinc phosphate, barium carbonate, calcium nitrate, and barium nitrate, magnesium compounds, aluminum compounds, barium compounds, lead compounds, zinc compounds, and silicate compounds. For example, if barium chloride is used as the first liquid and ammonium hydrogen phosphate is used as the second liquid, the barium cations and phosphoric acid anions will react, producing barium phosphate and barium hydrogen phosphate. Ru.

After the reaction is completed, the excess second liquid is removed by centrifugal deliquidation, washing with water using a shower, soaking, or the like. The second liquid immersion process and the liquid removal process may be repeated multiple times as necessary. After the liquid removal treatment, it is dried to a moisture content of 25% or less, preferably 7 to 15%. Since this nonflammable inorganic compound is water-insoluble, after drying, it fills in, adheres to, or adheres to the inside of the cell pores of the wood veneer or the inner wall surface of the cell pores, and also adheres to or adheres to the front and back surfaces of the wood veneer. Ru. As a result, the nonflammable inorganic compound is present in a form that blocks or fills the pores and cracks that appear on the surface of the wood veneer.

It is preferable that the nonflammable inorganic compound be mixed in at a ratio of 33% by weight or more to the wood veneer, and if it is less than this, sufficient fire protection performance cannot be obtained. Further, in order to increase the reaction efficiency between the first liquid and the second liquid, it is preferable that the addition and mixing of the second liquid be carried out under a heated atmosphere, particularly at a temperature of 40°C or higher, more preferably 50°C or higher. Alternatively, the first and second liquids may be heated and the wood veneer is immersed in them, or electrical or mechanical vibrations may be applied using ultrasonic waves, vibrators, etc. when immersing the first and second liquids. , the treatment solution diffuses and reacts well into the wood veneer. Note that the first
The order of treatment with the liquid and the second liquid does not matter, and it goes without saying that the treatment with the second liquid may be performed first. Nonflammable inorganic compounds that adhere to or adhere to the front and back surfaces of the wood veneer are removed by brushing, vacuuming, etc., as necessary.

In this way, a noncombustible wood veneer is obtained in which the cell pores and/or the inner wall surface are filled with or fixed with a noncombustible inorganic compound.

An adhesive substance is applied to at least one side of the obtained noncombustible wood veneer using an adhesive application device such as a blender, a sprayer, or a 70-coater. As the adhesive substance, synthetic resin adhesives such as urea resin, melamine resin, incyanate, urethane resin, epoxy resin, vinyl acetate resin, phenol resin, or modified resins thereof are preferably used. This adhesive substance is the same as a nonflammable inorganic compound that is filled or fixed to the cell pores and/or inner wall surface of the wood veneer.
Alternatively, different types of nonflammable inorganic compounds can be mixed and used, thereby further improving the fireproof performance of the furniture.

After laminating a plurality of noncombustible wood veneers coated with an adhesive substance, pressure bonding is performed using a pressing device such as a hot press or a cold press. When laminating a plurality of noncombustible wood veneers, the fiber directions may be arbitrarily orthogonal, or the fiber directions may all be in the same direction.

The laminated material thus obtained is used as a substrate, and the same adhesive substance as described above is applied to the front surface, front and back surfaces, or the entire front surface including the butt edge using the same adhesive coating device as described above. Apply. A nonflammable inorganic compound may also be mixed into this adhesive material.

Apply the adhesive to the adhesive application surface using a pasting device such as a press device, vacuum press device, or laminating device, or by using a manual.
