[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. The surface of the wood is coated and impregnated with multiple types of phytoncide obtained from different wood species. It is a composite board characterized by consisting of:

[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, multiple types of phytoncides obtained from different tree species are mixed. used together. For example, chips obtained from thinned Japanese mackerel and waste wood, A wood chip board made by laminating wood chips such as flakes and strands together using an adhesive. is used as a substrate, and the essential oil obtained from Togasawara is sprayed onto the surface of the substrate. An emulsion of phytoncide and essential oil obtained from cedar. The method includes applying mixed phytoncide, which is a mixture of phytoncide and After soaking and drying, the composite board of the present invention can be obtained. Also, Togasawara, Wood fibers obtained by defibrating softwood wood chips such as cypress, cypress, and cedar are used as adhesives. The substrate is wood fiberboard, which is made by laminating and integrating wood fiberboard, and is made of Japanese cypress, Japanese cypress, and birch. Phytoncides, which are microencapsulated essential oils, are added to synthetic resin paints. After applying and impregnating the mixture on the substrate surface using a roll coater, drying , a composite board according to the present invention can be obtained. Alternatively, it can be obtained by cutting lauan wood. Multiple veneers are laminated and bonded using adhesive so that the fiber directions are perpendicular to each other. The substrate is plywood obtained by Mixed phytoncide with each emulsion type was coated using a roll coater. After coating and impregnating, the composite board according to the present invention can be obtained by drying.

【Example】

FIG. 1 shows the structure of an embodiment of the composite board according to the present invention, and the substrate Togasawa Emulsion of essential oils obtained from Japanese cedar and Japanese cedar on the surface of a wood particle board 1 A coated and impregnated layer 2 of mixed phytoncide 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 in Multiple species of phytoncide obtained from different tree species are mixed. Since a mixed phytoncide is used, the functions of each phytoncide can be Can be combined arbitrarily, and the aromatic effect of phytoncide makes the substrate Emphasize the wood that makes up the board, or express a wood texture that is different from the wood that makes up the board. You can For example, you can make a miscellaneous tree look like a cypress, or emphasize the cypress. , to imitate hardwood materials to softwood materials or vice versa, to represent low-grade materials as high-grade materials, or to imitate high-grade materials. It is possible to express grade materials in a higher grade.
