DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction material for a building which enables a building to be inexpensively constructed and has a high-quality feeling in a completed building, and particularly relates to a flooring material and a wall material for a house. , Etc., as well as decorative surface materials, ascending frame materials, floor pillars, floor coverings, long pushes, etc., which can be used in place of those conventionally used as various building materials such as high quality wood or veneer for it. The present invention relates to a material and a reinforced decorative material used on the surface of such a building material or furniture.

[0002]

2. Description of the Related Art For a long time, building materials for buildings such as precious woods have been used as building materials for buildings, such as entrances and rising frames on floors. Due to the high cost and difficulty in obtaining such construction materials, 10 mm
In many cases, a thick plate was used as a substitute, but recently, a veneer (attached) has been used on the surface, and an inner core made of a plurality of plates has been used. Such technology is often found in patent applications, for example, see Jpn.
No. 36 and JP-A-63-184662 are examples thereof.

[0003] The up frame of the entrance or floor is usually the upper front edge (corner).
Has a large chamfer. In the case where the veneer is bonded to the surface of the integrated material, if the chamfer is largely performed, the core material is exposed, resulting in poor aesthetics. For example, in Japanese Utility Model Application Laid-Open No. 62-46736, as shown in FIG. 8, a corner member fitting groove 21 is provided in the upper front edge of a frame base material 20 made of an integrated material, and a corner member 22 having a chamfered surface is provided therein. And the protruding plate 23 is attached to the upper surface and the front surface of the corner member. In addition, JP 63
As shown in FIG. 9, a decorative material 24 having a chamfered surface is fitted on the upper front edge of the frame base material 20, and a veneer 23 is attached to the upper surface and the front surface of the decorative material 24. Material 24 is exposed.

[0004]

The conventional method of making a frame member using such an integrated material as a core material and using a veneer on the surface thereof requires a heavy measure on the chamfered surface so that the veneer can be used. , Which incurs high costs.
In addition, since the corner member 22 and the decorative material 24 are made of a different material from that of the veneer 23, the seam is conspicuous and unnaturalness remains. The inventor considered the use of thin veneers for the purpose of building inexpensive buildings, and made it possible to use veneers and paper not only for frame materials with a large chamfered surface but also for other building materials for building, as well as furniture etc. We considered to do it. Therefore, the base, laminated with veneer or paper, that is, also consider a synthetic resin with a large adhesive strength of the adhesive coating film to the veneer, and the synthetic resin veneer or wood grain printed paper, wood grain metal foil, or It is possible to provide a decorative decorative material laminated with a wood grain synthetic resin.

[0005]

Means for Solving the Problems The present invention, veneer or, using the laminated reinforcing the decorative material mosquitoes carboxylic acid-modified polyethylene Nfu <br/> Ilm to thin materials wood grain pattern printed paper, which laminated with wood material It is a building material made of a self-extinguishing synthetic resin foam, part of which is attached to the surface of a core material with the wood material side, and the veneer surface is resin-finished as required. The veneer is a thin wood of 0.2-0.6mm in precious wood, and the film is laminated on both sides or one side depending on the product specifications. The paper constituting the wood grain printing paper includes paper mixed with synthetic fibers or synthetic resin in addition to paper using ordinary pulp. The wood-grain synthetic resin does not emit toxic gas at the time of fire, that is, it does not contain halogen, especially, except for polyvinyl chloride. The wood material is plywood or timber, which is about 2 mm. Plywood is preferred in terms of price.

[0006] synthetic resin film used herein, the carboxylic acid modified polyethylene is most preferable in terms of bond strength of the veneer. This is obtained by introducing a carboxyl group into a polyethylene with many branched (one is the term in the synthetic resin film following the present invention is also a carboxylic acid-modified polyethylene). As a method for introducing a carboxyl group, for example, maleic acid is added to a terminal unsaturated group of polyethylene having many branched chains by graft polymerization.

[0007] The mosquito carboxylic acid-modified polyethylene Nfu Ilm is sliced veneer or, it is preferable to immediately laminate after molding into a film such as by the T-die method from a molten resin against the thin material of the grain pattern printed paper, pre-formed as a film What is done may be laminated by heating and melting. The present invention Cal Veneer of wood, the thin material of the grain pattern printing paper
It is possible to provide only a reinforced cosmetic material laminated with a boronic acid-modified polyethylene film to the general market, and to use it on the surface of various construction materials and furniture.

The self-extinguishing synthetic resin foam is a foam of polystyrene, polyethylene, urethane, etc., to which a known flame retardant or fire extinguisher has been added in order to enable self-extinguishing. . It is not always necessary to be non-combustible as long as it has self-extinguishing performance.

The present invention is also directed to a veneer, wood-grain printed paper, wood-grain metal foil, or a wood-grain synthetic resin thin material laminated with a synthetic resin film laminated on at least one surface thereof, and laminated with the wood. Side to any chamfer width
A double V-cut portion cut into two parallel V-shaped grooves as far away as possible is provided, and the wood material is added to the stacking material such that the double V-cut portion is located at the chamfered portion where the corner of the stacking material is cut. This is a building construction material that is glued to the sides and used as a frame material. Double V-cut portion, since Switching Operation grooves are provided at predetermined intervals (the width of the chamfered portion), the double V-cut portion will live up to the chamfer when bent.

[0010] The present invention further woody veneer, or carboxylic acid-modified poly to at least one surface of the thin material of the grain pattern printing paper
Reinforced decorative material laminated with ethylene film. This reinforcing decorative material gives wood-specific aesthetics and warmth (comfort) by being bonded to the surface of another member. The laminate layer helps to prevent the veneer from cracking, increases the strength of the V-cut thin portion, and enables the makeup to be applied to various building materials in its original shape to appear as a solid material. The production of such a veneer reinforcing decorative material has conventionally been difficult because it was difficult to obtain an endless veneer, that is, a long object. Since the veneer plate can be made as an endless product and can be wound, it can be used for lamination by a T-die method.

The present invention also provides a building construction material in which the periphery is a core material such as an integrated material or veneer core plywood, and the inside is a composite core material of a self-extinguishing synthetic resin foam. This composite core material enables inexpensive production, and also has effects of flame retardancy and weight reduction.

Further, the present invention is a construction material for a building, which is a decorative plywood obtained by attaching the reinforcing decorative material to a surface of a wooden material as a surface decorative plate. Even if the veneer is thinner than the conventional decorative plywood, a highly durable high-grade decorative panel with less cracking can be obtained.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION This reinforcing decorative material is bonded to a wooden material, and this is used as a part of the integrated material instead of the wooden material, and bonded to the surface of a core material using a self-extinguishing synthetic resin foam. When finished with resin (as needed in the case of double-sided lamination), it becomes a building material with a precious wood appearance, an inexpensive interior and self-extinguishing properties.

In particular, in the case of a structure provided with a double V-cut portion cut into two V-shaped grooves parallel to the wooden material side at the corner of the accumulation material, even if the corner is largely chamfered,
Since the reinforcing decorative material is well attached to the chamfered portion, a large chamfered portion can be formed without using other woody members for the chamfering, and the chamfered portion is suitable for a frame material of an entrance or a floor. V
If the cut part is 45 ° and two pieces are formed apart from each other by a distance covering the width of the chamfered part, the chamfered part is formed well at the corner of the square material, and a high-grade frame material is obtained.

By making the veneer, wood grain metal foil, or a synthetic resin film laminated with a wood grain pattern synthetic resin into a reinforcing decorative material, the veneer has sufficient strength even if the veneer is thin (0.2 to 0.6 mm). And has the flexibility to adhere well to the bonding partner. It can also be used as wallpaper instead of luxury cloth. In addition, it can be used as a luxury decorative board by using on the surface of cheap softwood or veneer core plywood,
Further, it can be used as a frame material and a door material by covering the outer periphery of a pulp fiber board, a gypsum board and the like, as high-grade wood.
