Description

[Detailed description of the invention] <Industrial application 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 is usually made of wood at least in its main body in order to satisfy requirements such as workability, design, feel, weight, and price.

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 noncombustible or semi-noncombustible 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, making it impossible to achieve sufficient fire prevention objectives with the restrictions under the Building Standards Act alone. There was a problem. 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 Problems> The above problems are achieved by molding and integrating nonflammable organic fibers with nonflammable inorganic compounds filled or fixed in the cell pores and/or inner wall surfaces through an adhesive substance. The problem is solved by furniture characterized in that at least a part of the structural member is a decorative board made of fiberboard as a substrate and a decorative sheet-like material affixed to the front surface, front and back surfaces of the substrate, or the entire surface including the wood edge. be done.

Furniture is generally made up of a top plate, bottom plate, side plates, and back plate, into which parts such as doors, doors, drawers, shelves, etc. are incorporated as appropriate, and metal fittings such as hinges, handles, rails, door wheels, etc. are also attached. and formed.

At least some of the structural members of the furniture of the present invention, particularly the decorative laminate used as the board material of the furniture body, are made of nonflammable organic fibers filled with or fixed to the cell pores and/or the inner wall surface of a nonflammable inorganic compound. The substrate is a fiberboard formed integrally through an adhesive substance, and a sheet-like material is adhered to the front or back surfaces of the substrate, or the entire front surface including the butt edge.

The organic fibers used in the present invention are, for example, softwood materials such as pine, cedar, and cypress, or lauan, capor, chestnut, poplar, etc.
Wood chips are made by appropriately mixing one or more types of hardwood materials such as willow, which are steamed under high-temperature and high-pressure steam to be defatted and softened, and then defibrated using a defibration device, Fiber length is 1 to 30mm, thickness is 2 in diameter
The majority are about ~300μ. These organic fibers have the shape of several to dozens of cell pores consisting of wood cells, duct pores, or tracheid pores, and the cell walls around the fiber periphery are not torn or cracked. Often. Bayas obtained by defibrating sugar cane, corn stalks, coconut shells, etc. into chips can also be used as an organic fiber.

The obtained organic fiber is dried to reduce its moisture content from 7 to 15.
It is adjusted to about %.

By filling the voids such as cell pores and conduit pores in the dried organic fibers with a nonflammable inorganic compound, or by fixing or covering the nonflammable inorganic compound in a layer along the inner wall of the cell pores, nonflammable organic fiber is obtained. This nonflammability treatment can be performed, for example, by the following steps. That is,
The organic fibers are sufficiently immersed in an aqueous solution of a water-soluble inorganic salt (hereinafter referred to as "first solution") to be impregnated. At this time, it is effective to forcibly accelerate the impregnation treatment by applying reduced pressure or increased pressure. Alternatively, the organic fibers may be brought into a high moisture content state without drying, or after drying, they may be immersed in water or hot water to absorb water to become saturated with water, and then immersed in the first liquid for diffusion impregnation. It's okay. As the first liquid, M g

) z and other aqueous solutions are exemplified. By immersing the organic fiber in the first liquid, ions of the inorganic salt of the solute diffuse into the cell pores of the organic fiber.

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, java or dobuzuke washing, etc., and by removing the excess first liquid, it is possible to avoid excessive production of nonflammable inorganic compounds on the surface of the organic fibers. suppresses and improves diffusion impregnation of the aqueous solution to be impregnated next. It also prevents nonflammable inorganic compounds from being produced in a free state that is not attached or fixed to organic fibers.

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 organic fibers using a blender, spray, etc., or immersed. The organic fibers are impregnated with the second liquid by allowing the organic fibers to soak. As in the case of the first liquid, impregnation of the second liquid into the organic fibers can be promoted by treatment under reduced pressure or pressure. The second liquid is Na2CO.

Examples include NH, BO, etc. By applying or dipping the second liquid, the second liquid is diffused and impregnated into the cell pores of the organic fiber, and the first liquid and the second liquid react in the organic fiber.
Nonflammable inorganic compounds are produced.

The nonflammable inorganic compounds produced are magnesium phosphate, calcium phosphate, and barium phosphate.

Aluminum phosphate, magnesium borate, magnesium carbonate, calcium carbonate, zinc phosphate, barium carbonate,
Carunium compounds such as calcium nitrate and barium nitrate,
Examples include magnesium compounds, aluminum compounds, barium compounds, lead compounds, zinc compounds, and silicate compounds. For example, if the reaction is performed using barium chloride as the first liquid and ammonium hydrogen phosphate as the second liquid,
Barium cations and phosphate anions react,
Barium phosphate and barium hydrogen phosphate are made into live spheres.

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 is filled in, adhered to, or fixed to the inside of the cell pores of the organic fiber or the inner wall surface of the cell pore, and is also attached to or fixed to the outer periphery of the organic fiber. As a result, the nonflammable inorganic compound is present in a form that blocks or fills the pores and cracks appearing on the surface of the organic fibers.

It is preferable that the nonflammable inorganic compound is mixed in at a ratio of 33% by weight or more based on the organic fibers, and if it is less than this, sufficient fireproof 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 is carried out under a heated atmosphere, particularly at a temperature of 40°C or higher, more preferably 50°C or higher. Alternatively, the organic fibers may be immersed in the first and second liquids in a warm water state, or electrical or mechanical vibrations may be applied by ultrasonic waves, pie breaks, etc. when the first and second liquids are immersed. , the treatment liquid can diffuse and react well into the organic fibers. Note that the order of the treatment with the first liquid and the @2 liquid does not matter, and it goes without saying that the treatment with the second liquid may be performed first.

In this way, a nonflammable organic fiber is obtained in which a nonflammable inorganic compound is fixed in the cell pores or on the inner wall surface, and a nonflammable inorganic compound is also fixed or adhered to the outer periphery of the cell pore, thereby making it nonflammable.

Next, this nonflammable organic fiber is put into a mixing device, and an adhesive substance is added and adhered thereto. In the mixing device, arbitrary additives such as a water generating agent and a smoke reducing agent can be mixed at the same time as necessary. As the adhesive substance, synthetic resin adhesives such as urea resin, melamine resin, isocyanate, urethane resin, epoxy resin, vinyl acetate resin, phenol resin, and modified resins thereof are preferably used. If necessary, the adhesive substance is filled or fixed in the cell pores of organic fibers, etc.; non-flammable inorganic compounds of the same type or different type can be added and mixed with the non-flammable inorganic compound, thereby making it possible to use it as furniture. The fire protection performance of the system will be further improved.

The noncombustible organic fibers to which the adhesive substance has been attached are conveyed by air to form a noncombustible organic fiber mat, which is then cut and integrated by hot pressure molding to obtain a noncombustible organic fiberboard.

This noncombustible organic fiberboard 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 end edges, using the same adhesive application surface position as described above. . Similarly, a nonflammable inorganic compound can 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.
A decorative sheet is attached to obtain a decorative board. As the decorative sheet-like material, decorative paper, veneer, decorative vinyl chloride sheet, lipometric impregnated decorative paper, etc. are suitably used. It is preferable to use a decorative sheet-like material having fire prevention performance higher than flame retardancy.

The furniture of the present invention is constructed by using this decorative board as the top plate, bottom plate, side plate, back plate, etc. of the furniture body.

<Function> Furniture is constructed using a fiberboard as a substrate, which is made by adhesively molding noncombustible organic fibers with noncombustible inorganic compounds filled or fixed in the cell pores and their inner walls, improving fire protection performance. be done.
