[Structure] The surface of a wood-based substrate is coated and impregnated with phytoncide obtained from a different species of wood from the wood constituting the substrate.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a composite board for construction that has insect repellent, antibacterial, and aromatic properties.

0002

[Conventional technology]

In recent years, advances in construction methods and materials have led to improvements in soundproofing, fireproofing, and energy saving. In line with the demand for air-tightness, the airtightness of houses and rooms has been significantly improved. However On the other hand, when airtightness is improved, air stagnates in the house and each room, causing humidity to increase. Because of this, problems such as household odors not being removed and condensation becoming more likely to occur occur. Ru. These problems are especially common in kitchens, washrooms, bathrooms, storage areas such as closets, living rooms, etc. It is noticeable in the environment, and is accompanied by discomfort due to household odors, as well as mold and mildew caused by condensation and moisture. This creates an environment suitable for the occurrence and reproduction of ticks, bacteria, cockroaches, etc. It becomes a breeding ground for these substances, is harmful to the human body, and has a negative impact on environmental hygiene and health. It was causing the damage.

0003

[Problem that the idea aims to solve]

In view of this current situation, some building materials treated with insect repellents and preservatives are being proposed. However, considering the effects of processing chemicals on the human body, it is not necessarily satisfactory. This could not be a solution.

0004

[Means to solve the problem]

The present invention, which was created after intensive efforts to solve this problem, is a wood-based substrate. on the surface of the substrate, phytoncide obtained from a different species of wood from the wood constituting the substrate. This is a composite board characterized by being coated and impregnated with.

[0005] Wood-based substrates include plywood, wood fiberboard, wood chipboard, and veneer laminates (LVL, L VB), sawn wood, decorative veneer, etc. In addition to natural wood decorative veneers, decorative veneers include It may also be an artificially decorated veneer obtained by laminating boards and then optionally cutting them.

[0006]After coating and impregnating phytoncide on the surface of the substrate using a coating device, the composite plate of the present invention is obtained by drying. Phytoncide is an essential oil obtained by refining natural trees (trunks, branches, leaves, roots, bark, resin, etc.) by distillation, squeezing, solvent extraction, etc. Monoterpenes such as pinene, dipentel, limonene, _and terpinolene, sesquiterpenes such as cadinene and longifolene, and diterpenes such as campholene and _mylene . It is called oil. The phytoncide tree species may be any tree species such as cedar, cypress, cypress, pine, birch, Japanese pine, catfish, camphor tree, sawtooth oak, ginkgo, and camellia.

[0007] Phytoncides can be used as an essential oil (sometimes diluted with a solvent) or as an emulsion. Microphone that is coated and impregnated on the surface of the substrate as John type, or that has essential oil sealed inside. Disperse this in water, synthetic resin, etc. using a microcapsule type product and then surface it on the substrate. The surface is coated and impregnated. Phytoncides used in essential oil form are not released into the atmosphere. Because it is relatively fast, it is quick-acting and has a large short-term effect. When used as a microcapsule type, it has a slow-acting and long-lasting effect. can be expected. Furthermore, in the case of emulsion type and microcapsule type, , the materials constituting the emulsion shell or microcapsule shell, and the thickness of the shell/shell. By changing the temperature, the amount of phytoncide emission can be controlled appropriately. can.

[0008] Although phytoncides differ slightly depending on the tree species, they can be used to kill bacteria, miticides, insecticides, and kill insects. It has many functions such as antimicrobial, antibacterial, pharmacological, deodorizing, aromatic, and sedative. for example The phytoncide of Japanese cedar has particularly excellent bactericidal, acaricidal, and deodorizing functions; Hinoki cypress has particularly excellent antimicrobial and bactericidal functions, and phytoncide from cypress has particularly antibacterial and decontaminating properties. It has an excellent odor function, and the phytoncide of Togasawara has particularly excellent insecticidal, bactericidal, and helminthicidal functions. The phytoncides in birch have particularly excellent antibacterial and insecticidal functions. Also phyto Chid has a forest bathing effect on the human body and has excellent environmental health and health effects. ing.

[0009] In this invention, phytochemicals obtained from wood of a different species than the wood constituting the substrate are used. ntid is used. For example, chips and flakes obtained from lauan waste, Wood chips such as strands are defibrated into wood fibers, which are laminated together using adhesive. A wood fiber board made of wood fiberboard is used as a substrate, and the surface of the substrate is sprayed with wood fiberboard. After applying and impregnating phytoncide, which is an emulsion of the obtained essential oil, drying After drying, the composite plate of the present invention can be obtained. We also have equipment for cutting spruce wood. A plurality of veneers obtained by cutting the veneer using the Laminated veneer lumber (LVL) is obtained from cypress by laminating them together using an adhesive. A mixture of phytoncide, which is microencapsulated essential oil, in a synthetic resin paint. was coated and impregnated on the surface of the veneer laminate using a roll coater, dried, and then A composite board can be obtained according to the invention.

【Example】

FIG. 1 shows the structure of an embodiment of a composite board according to the present invention, in which the substrate lauan is On the surface of the wood fiber board 1, an emulsion-type filament containing essential oil obtained from Hiba is applied. A coated and impregnated layer 2 of Tonchid is formed.

[0011]

[Effect of the idea]

A coated and impregnated layer of phytoncide with many excellent functions is formed on the substrate surface. As phytoncides are dissipated into the atmosphere, their function gradually decreases. It is demonstrated. Phytonchip obtained from wood of a different species than the tree constituting the substrate. Since phytoncide is used, the aromatic effect of the phytoncide makes it possible to structure the substrate. It is possible to express a feeling of wood that is different from other trees, for example, to imitate a miscellaneous tree to a cypress, It is not possible to imitate hardwood materials to softwood materials or vice versa, or to imitate low-grade materials to high-grade materials. I can do that.
