Abstract

PROBLEM TO BE SOLVED: To settle a resource impoverishment problem and obtain a floor board, which has a high strength, a small thermal strain and antifungal properties by a method wherein sliced veneers obtained from the surface layers of bamboos are bonded onto the top surface of a laminate, which is produced by laminatingly bonding wooden veneers or veneers, each of which is obtained by slicing bamboos in a cutting manner with a veneer lathe. SOLUTION: By laminatingly bonding the necessary number of veneers, each of which is obtained by slicing a portion except the skin layer of a thick-stemmed bamboo in a cutting manner with a veneer lathe into a predetermined thickness, in such a manner the fibers of bamboos intersect normal to each other, a laminated sheet 3 is obtained. By pasting flat plate-like sliced veneers 2 having a predetermined thickness gathered from the skin layers of thick-stemmed bamboos onto the surface of the laminated sheet 3, a floor board 4 is obtained. As an adhesive, one is properly adopted by being selected from the group consisting of a urea resin-based-, a melamine resin-based-, a phenolic resin-based-adhesive or the like. The surface and both the sides of each of the sliced veneers 2 are polished and finished so as to bring the adjacent sliced veneers 2 into close contact with each other and bonded without forming a gap between the adjacent portions in the pasting of the sliced veneer 2 to the surface of the laminated sheet 3. Thus, a resource impoverishment problem is settled and a floor board having a high strength, a small thermal strain and showing antifungal properties is realized.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flooring and a rug that are made of bamboo and have high strength, small thermal distortion and antibacterial properties.

[0002]

2. Description of the Related Art The depletion of plywood materials has long been called out due to the deforestation of tropical rainforests, and planting of conifers that grow quickly has been studied, but the problem of resource depletion has not been solved.

On the other hand, there is a large bamboo forest area of Moso bamboo which is said to be a bamboo mountain range in southern China, northern Vietnam and northern India. In addition, the diameter is 10 to 15 cmφ, the interval between nodes is 40 to 45 cm, the thickness is 2 It is said that it grows up to 3cm and becomes matured bamboo in 3 years and becomes the most suitable condition as lumber. If left as it is, it will overgrow and wither, and must be thinned out. It is noted that there is no.

[0004]

SUMMARY OF THE INVENTION In view of the above situation, the present invention solves the problem of resource depletion by using Moso bamboo as a material, and provides a floor material having high strength, low thermal strain, and antibacterial properties. It is intended to provide a rug.

[0005]

In order to solve the above-mentioned problems, the invention of claim 1 is to laminate and adhere a wooden veneer or a veneer sliced from bamboo to form a bamboo skin. The structure is formed by bonding a veneer sampled from the above.

According to a second aspect of the present invention, a wooden veneer and a veneer obtained by slicing bamboo in a katsura shape are laminated and adhered, and a veneer sampled from a bamboo skin layer is adhered to the upper surface thereof. It is.

In a third aspect of the present invention, a single plate obtained by slicing bamboo in a stripped shape is laminated and bonded so that the fibers thereof are orthogonal to each other to form a laminated plate. It has a configuration in which veneers are bonded in parallel.

According to a fourth aspect of the present invention, a veneer sampled from a bamboo skin layer is directly or indirectly attached to a flexible backing material.

According to a fifth aspect of the present invention, the backing material is selected from a plastic sheet, a woven fabric, a nonwoven fabric, and a linen fabric.

[0010] The invention according to claim 6 is that, between the veneer and the backing material, a veneer or a wooden veneer obtained by slicing a portion excluding the bamboo skin layer into a katsura shape, excluding the bamboo skin layer. The veneer has a structure in which a veneer and a veneer veneer which are sliced in a stripped shape are interposed and bonded.

According to a seventh aspect of the present invention, the cushioning layer is added to the rug.

In the present invention configured as described above,
Utilizing the property of extremely high strength in the fiber direction, fibers are laminated and bonded so that they are orthogonal to each other, have high strength in both vertical and horizontal directions, have low thermal distortion, and have antibacterial properties Flooring and rugs can be provided.

[0013]

Next, a first embodiment according to the present invention will be described with reference to FIG. Moso bamboo excluding the skin layer is sliced in a 0.3 mm to 0.8 mm thickness to form a veneer 1 in a katsura shape, and the required number of veneers 1 are stacked so that the bamboo fibers are orthogonal. The laminated plate 3 is adhered to obtain a plate-shaped veneer 2 having a thickness of 1 to 3 mm and a width of 6 to 12 mm from the skin layer of Moso bamboo, and the veneer 2 is attached to the surface of the laminated plate 3. Was obtained.

The above dimensions are merely examples, and may be changed as appropriate according to the dimensions of the entire flooring and the manufacturing conditions. In addition, as the adhesive used for manufacturing the floorboard, a known adhesive such as a urea resin, a melamine resin, or a phenol resin can be appropriately used.

It is desirable that the above-mentioned veneer is finished by polishing the surface and both side surfaces so that the adjacent veneers are in close contact with each other. Further, when bonding to the surface of the laminated board, the bonding is performed while making no gap in the adjacent portion.

The bonding of the laminate and the bonding of the laminate and the veneer are performed by uniformly applying an adhesive to the veneer, laminating a required number of bamboo fibers so that the fibers are orthogonal, and placing the bamboo between the platens. A laminated plate 3 is created by pressing and heating with a hydraulic press, an adhesive is evenly applied to the surface of the laminated plate 3, and the veneers are arranged in close contact with each other, placed between the platens, and pressurized and heated by a hydraulic press. Thus, floor material 4 was obtained.

In the above embodiment, the protruding plate 2 has a thickness of 1 to 1.
Although the thing of 3 mm and the width of 6 to 12 mm was adopted, it is also possible to adopt a bamboo skin layer sliced into a 0.3 mm to 0.8 mm thickness in a strip shape. Further, all or a part (for example, lower three) of the veneers 1 constituting the laminated board 3 may be a wooden veneer.

Next, a second embodiment according to the present invention will be described with reference to the drawings. Plastic sheet, woven cloth,
On a backing material 10 selected from nonwoven fabric and linen,
Alternatively, veneer sliced bamboo sliced veneer 11 is directly laminated with fibers and laminated and bonded to laminate 13, on which a plate-shaped veneer having a thickness of 1 to 3 mm and a width of 6 to 12 mm from the bamboo skin layer. 1
2 was collected and bonded to form a rug 14.

The laminated plate 13 is made of wood and bamboo veneer 1.
1 may be mixed, and the thickness is 1 to 3 mm and the width is 6 to
Instead of the 12 mm plate-shaped veneer plate 12, a bamboo skin layer may be sliced to a thickness of 0.35 mm to 0.8 mm in a stripped shape.

The cushioning material 1 is added to the backing material 10.
5 may be adhered and the veneer plate 11 and the veneer plate 12 may be sequentially laminated thereon.

[0021]

As described above, according to the present invention, the problem of resource depletion is solved, the strength is high, the thermal strain is small,
Moreover, a flooring material exhibiting an antibacterial effect is provided. Particularly, it is most suitable for floor materials for floor heating because of small thermal distortion.
