Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-like body using a coconut shell.

[0002]

2. Description of the Related Art Conventionally, there is a particle board (chipboard) that reuses small waste materials such as wood waste.

This is a product in which wood chips such as waste processing materials and veneer scraps are mixed with a synthetic resin adhesive such as urea resin and molded into a plate shape by pressing and the like. In this particle board, those having various properties are obtained depending on the raw material, the compound, and the manufacturing method. Generally, the specific gravity of the product is 0.2.
In the range of 5 to 1.20, those having a thickness of about 4 mm to 40 mm are obtained. Such particle boards are mainly used for building materials and furniture materials.

[0004]

However, since the piece of wood itself which forms such a particle board does not have a molding ability, it is not possible to manufacture a particle board with only the piece of wood. Therefore, as described above, the wood pieces must be solidified with a synthetic resin adhesive such as a urea resin, and there is a problem that the wood piece cannot be easily manufactured with only the waste material.

Further, since the waste material has a peculiar odor, the peculiar odor remains in the obtained particle board, which makes it difficult to manufacture a particle board having a desired scent.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a plate-like body which can be easily manufactured and has a desired scent.

In a plate-shaped body using a coconut shell according to claim 1, a plurality of cut pieces obtained by cutting the coconut shell into a desired size are mixed with a fragrance at a predetermined mixing ratio. Then, the integration was used as a means for solving the problem.
Here, in order to integrate the cut pieces and the fragrance, a mixture of the cut pieces and the fragrance may be put into a mold having a predetermined shape and press-molded at a predetermined pressure. Further, this mixture may be solidified and integrated with a synthetic resin adhesive such as urea resin.

In the plate-shaped body using the coconut rind of claim 2, a plurality of cut pieces obtained by cutting the coconut rind into a desired size are mixed with a fragrance at a predetermined mixing ratio to obtain 50.
Molding at a pressure of kg / cm ² or more was used as a means for solving the problem. Here, the pressure is set to 50 kg / cm ² or more because only a brittle and easily collapsed compressed body can be obtained when molding is performed at a pressure of less than 50 kg / cm ² .

Herbs are preferable as the fragrance, and it is preferable to use hyssop with a clean scent, thyme with a refined scent, and lavender with a refreshing scent, as well as rosemary, savory, lemon balm, peppermint and the like. You can

[0010]

The coconut rind has a small specific gravity of about 0.06 to 0.1 and is composed of wood fiber and contains a large amount of fibers and porous wood parts. When the two are compressed, the voids are reduced and the wood fibers are intricately entangled with each other to integrate the cut pieces. At this time, if molding is performed with a pressure of 50 kg / cm ² or more, a lightweight plate-like body that does not collapse even without an adhesive can be formed.

Since the coconut shell itself has no odor, a plate-like body having a desired scent can be formed by mixing a fragrance having a desired scent.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A plate-like body using the coconut shell of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an embodiment of a plate-like body using the coconut shell of the present invention. This plate is
The coconut shell 2 is obtained by mixing a plurality of cut pieces 6 ... 30g cut into a desired size and lavender 7 ... 15g and integrating them.

A method of manufacturing such a plate-like body will be described with reference to FIGS.

FIG. 2 is a cross-sectional view showing coconut which is a raw material for the plate-shaped body. The raw material coconut has a substantially spherical core and an outer skin 2 that thickly covers the core. This core is composed of an inner shell (core shell) 3, a flesh 4 formed thickly on the inner surface of the inner shell 3, and a juice 5 in the inner portion of the flesh 4.

The plate-like body using the coconut shell according to the present invention uses the shell 2 as a material. First, only the outer skin 2 is stripped from the coconut, and then cut into a desired size. To cut the outer skin 2, a known cutting machine such as a cutting machine used in the production of wood fragments can be used, and a machine capable of cutting a granular material having a uniform shape and a uniform size is particularly preferable. Is.

The cut pieces 6 obtained by cutting are sieved if necessary. Furthermore, it is desirable to prevent the mixture of pests by subjecting the cut pieces 6 ... to steam sterilization.

FIG. 3 shows cut pieces 6 cut into various sizes.
FIG. 3A shows an aggregate of cutting pieces 6 in a relatively large lump. In addition, FIG.
It is an assembly of granular cut pieces 6. Further, FIG. 3 (c) shows an assembly of powdery cut pieces 6 ... Containing a large amount of cut and separated fibers.

The plate-shaped body of this embodiment has the above-mentioned structure shown in FIGS. 3 (a), 3 (b),
30 g of the cut pieces 6 ... Shaped as shown in (c) and 15 g of dried lavender pieces 7 ... 15 g as shown in FIG. 4 are mixed and then used in the conventional powder molding. It can be obtained by pressing in a press machine at a predetermined pressure in a press machine. At this time, the pressure at the time of pressing can be changed according to the application of the plate-shaped body to manufacture plate-shaped bodies having different strengths and specific gravities. The plate-shaped body thus formed by pressing does not need to use a synthetic resin adhesive such as a urea resin, and has an advantage that it can be easily manufactured using only coconut and herbs. Further, since no synthetic resin adhesive is used, there is an advantage that the scent of herbs is easily emitted. Further, in the case of producing a plate-shaped body having a particularly small specific gravity, the mixture of the cut pieces 6 ... And the lavender pieces 7 ... You can also

Since the plate-like body produced in this way is lightweight and has a good scent, it is used for mats used for bedding, pillows, inner wall materials, shoulder pads, underlays for figurines, stands for dried flowers, shoes, etc. It can be suitably used for insoles, shoe boxes, and the like.

The cut pieces 6 used for this plate-like body ...
Is not limited to the cutting pieces 6 having only the shapes shown in FIGS. 3 (a), (b), and (c), and cutting pieces cut into various shapes can be used.

(Experimental Example) When a foreign substance such as an herb is mixed in the coconut shell, it is considered that the physical properties and strength are naturally changed, but in that case, the shape and physical properties of the mixture pose a problem. The influence of mixing is small for herbs that are fibrous and have similar physical properties to the coconut rind. (In the experiment, we tried to mix the herbs (lavender, lemongrass) up to 40% by weight, but no big difference was observed.) The physical properties of the molded product are only the coconut hull alone, which does not contain any Can often be deduced from the use of. As an experimental example, changes in the physical properties of the coconut hull alone due to the compression pressure are shown.

[0023]

[Table 1]

From this result, the compression pressure was 50 kg / cm ²
As described above, it was found that the molded product can be used as it is without an adhesive because it retains its compressed shape.

[0025]

As described above, in the plate-shaped body using the coconut shell of the present invention, a plurality of cut pieces obtained by cutting the coconut shell into a desired size and the fragrance are mixed at a predetermined mixing ratio. Since they are integrated with each other, a lightweight plate-like body can be easily formed. At this time, if a mixture of the cut pieces and the fragrance is molded at a pressure of 50 kg / cm ² or more, a lightweight plate-like body that does not collapse even without an adhesive can be formed.

Further, since the coconut shell itself has almost no odor, it is possible to form a plate-like body having a desired scent by mixing a fragrance having a desired scent.

Therefore, the plate-like body using the coconut shell of the present invention is a mat underlay used for betting, a pillow, an inner wall material, a shoulder pad, an underlay of a figurine, a stand for dried flowers, etc.
It can be suitably used for shoe insoles, shoe boxes, and the like.
