BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wood shaving plate obtained by pressing and adhering wood shavings obtained by cutting wood with an adhesive. For wood shavings boards that demonstrate.

2. Description of the Related Art A wood shaving plate obtained by pressing and adhering wood shavings obtained by cutting wood with an adhesive is well known and is widely used as a building material or a furniture material in houses. .

[0002]

[Problems to be Solved by the Invention] In recent years, the airtightness of houses has been improved due to the progress of construction methods and building materials. This improvement in airtightness is beneficial from the viewpoint of soundproofing and energy saving, but as a result of the retention of air in the room and the increase in temperature and humidity, problems such as the generation of living odors, the occurrence of dew condensation, and the propagation of various bacteria are apparent. Has come to change. The retention of air and the increase in temperature and humidity due to the high degree of airtightness are particularly noticeable in kitchens, washrooms, bathrooms such as baths, closets, storage doors, under floors or storage areas such as ceilings, and molds, mites, and bacteria. ,
It becomes a hotbed suitable for the generation and breeding of cockroaches, which poses a serious environmental and health problem.

In the wood slabs that have been generally used in the past, no consideration has been given to such a problem.

[0004]

Therefore, the present invention solves the above-mentioned drawbacks of the prior art and provides a wood shaving plate capable of exerting the effects of fragrance, insect repellent, fungus prevention, etc., and has a high airtightness. It is an object of the present invention to enable it to be used suitably as a building material or a furniture material in a house having.

In order to achieve this object, the wood shaving plate according to the present invention comprises a wood shaving obtained by cutting wood, and a treated wood shaving obtained by applying and impregnating phytoncide on the wood shaving, and then pressing it with an adhesive. It is characterized by being bonded.

The wood shaving plate according to the present invention is obtained as follows. First, coniferous trees such as cedar, cypress, hiba, pine, birch, maki, cat, camphor, kunugi, ginkgo, camellia, spruce, rawan, kapole, chestnut, poplar, willow, agatis, zelkova, oak, sen, teak, oak. Wood or hardwood is cut into chips, flakes, strands, etc. using a cutting device to obtain wood chips. The wood shavings used in the present invention may be composed of a single tree species or may be a mixture of a plurality of tree species.

The wood chips obtained are adjusted to an appropriate water content by drying and then sent to a mixing device where phytoncide is added and mixed therewith, and thus the surface of the wood chips is coated and impregnated with phytoncide. Phytoncide is a natural tree (stem,
(Branch, leaves, roots, bark, resin, etc.) is an essential oil obtained by purification by distillation, pressing, solvent extraction, etc., and specifically,
Main components are monoterpenes such as α-pinene, β-pinene, dipenterene, limonene and terpinolene, sesquiterpenes such as kazinene and longifolene, and terpenes such as diterpenes such as camphorene and mylene = (C ₅ H ₈ ) n = Therefore, it is generally called turpentine oil.

[0008] Phytoncide is added to and mixed with wood chips as an essential oil state (which may be diluted with a solvent) or as an emulsion type, or a microcapsule type in which an essential oil is encapsulated is used as water. , And mixed in a state of being dispersed in a synthetic resin or the like. Phytoncide used in essential oils has a short-term effect due to its relatively rapid release into the atmosphere, and has a long-term effect.When used as an emulsion type or microcapsule type, it has a long-acting and long-lasting effect and has a long-term effect. The effect can be expected. Furthermore,
In the case of the emulsion type or the microcapsule type, the emission amount of phytoncide can be appropriately controlled by changing the thickness of the substance constituting the emulsion shell or the microcapsule shell or the shell / shell.

Phytoncide tree species include cedar, cypress,
It may be any of Hiba, pine, birch, maki, Neko, camphor, sugi, ginkgo, camellia, Togasawara, etc. In some cases, phytoncide obtained from other plants can also be used. Phytoncide, although slightly different depending on the tree species, sterilize, acaricide, insecticide,
It has many functions such as insecticidal activity, antimicrobial activity, antibacterial activity, pharmacology, deodorization, aroma, and sedation. For example, phytoncide of cedar is particularly excellent in sterilization, acaricide, deodorizing function, phytoncide of Hiba is particularly excellent in antimicrobial and insecticidal functions, phytoncide of Hinoki is particularly excellent in antibacterial and deodorizing functions, and phytoncide of Togasawara is particularly insecticidal, bactericidal, The phytoncide of birch is particularly excellent in antibacterial and insecticidal functions. Phytoncide also exerts a forest bathing effect on the human body, and has excellent environmental health and health effects.

In this way, the treated wood shavings whose surface is coated and impregnated with phytoncide are mixed with an adhesive in a mixing device after or without being dried. The order of applying and impregnating the adhesive and phytoncide is not limited to this, and the phytoncide may be applied and impregnated after the adhesive is first applied by the mixing device. As an adhesive, urea resin,
Phenol resin, melamine resin, epoxy resin, vinyl acetate resin, ethylene-vinyl acetate resin, urethane resin,
Any thermosetting or thermoplastic adhesive such as synthetic resin adhesive such as acrylic resin or modified resin thereof, isocyanate adhesive, rubber or synthetic rubber adhesive is used.

The treated wood shavings to which the adhesive has been applied are then conveyed by air to form a wood shaving mat, which is then cut to a predetermined size and further pressure-molded and integrated to obtain a wood shaving plate of the present invention. To get

In the present invention, the phytoncide applied and impregnated on the wood chips may be one or more kinds obtained from the same wood seed material as the wood chips used, or may be obtained from a different wood species material. It may be one kind or a plurality of kinds, and it is also possible to mix and use those obtained from the same tree seed material and those obtained from different tree seed materials. For example, wood shavings of Togazawara are coated and impregnated with phytoncide, which is also obtained from Togazawara, to give treated wood shavings, which are then coated with an adhesive and molded and integrated as described above to form wood shavings boards. You can In this wood shaving plate, the phytoncide of Togasawara is gradually released over a long period of time, and exhibits insecticidal, bactericidal, and insecticidal functions.

Further, for example, wood chips of Lauan wood are coated and impregnated with microcapsules enclosing phytoncides obtained from different tree species, for example, Hiba, and then the treated wood chips are coated with an adhesive to obtain the above-mentioned materials. It can be integrated into a single piece to form a wood shaving plate. In this wood slab,
While using wood shavings of relatively inexpensive tree species, the fragrance of phytoncide of high-grade tree species such as Hiba can be obtained, so that it can be simulated as a wood shaving plate of high-grade tree species.

By using treated wood chips obtained by mixing and impregnating wood chips with a mixture of phytoncides of a plurality of tree species, a wood chip plate having the functions of each phytoncide can be obtained. For example, when Hiba phytoncide and cedar phytoncide are mixed and used, the antimicrobial and insecticidal functions of the Hiba phytoncide and the bactericidal, acaricidal and deodorizing functions of the cedar phytoncide are exhibited. In this way, by using the phytoncides of a plurality of tree species in an arbitrary combination, it is possible to obtain a wood shaving plate having a desired function.

The wood shavings board may be a single layer board, but
It may be a multi-layer board or more multi-layer boards.
When it is composed of a plurality of layers, it is desirable to use treated wood shavings coated and impregnated with phytoncide as wood shavings in at least the front surface layer and / or the back surface layer.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a wood chip board 1 having a three-layer structure formed by using wood chips of Togasawara as an embodiment of the present invention.
As the wood chips of Togazawara used for at least the front and back layers 2 and 3, treated wood chips obtained by applying and impregnating phytoncide obtained from Togasawara are also used.
Thus, these front and back layers 2 and 3 contained phytoncide, and the function of the phytoncide of Togasawara was exhibited for a long period of time.

[0017]

[Effects of the Invention] Since the treated wood chips, in which phytoncides are applied and impregnated on the wood chips, are pressure-bonded with an adhesive, the phytoncides are gradually diffused into the atmosphere, and their function is long. Delivered continuously over a period of time.
In the wood shavings plate of the present invention, aroma can be obtained from the phytoncide of the desired tree species which is applied and impregnated on the wood shavings, so that it is possible to express a high-class wood texture even when using wood shavings made of low-grade wood. it can. Furthermore, it is possible to exert the peculiar effects such as sterilization, insecticide, and deodorization of the phytoncide used.
