Description

DETAILED DESCRIPTION OF THE INVENTION A. Object of the Invention (Industrial Utilization) The present invention relates to a method for treating wood using natural plant essential oils to achieve effects such as deodorization, sterilization, and fragrance.

(Conventional technology) As an air purifying and deodorizing device for the purpose of deodorizing, sterilizing, fragrance, etc., which has been conventionally used in general households, etc., it is made from various essential oils extracted from natural trees in a special polymer membrane (membrane). The container is filled with natural plant essential oil, placed in a container, placed in an appropriate location in a room, and released as fine particles through the dialysis reverse osmosis, gas separation, and sustained release effects of the special polymer membrane. It uses natural plant essential oils to deodorize, sterilize, and scent the room.

(Problems to be Solved by the Invention) However, since the above-mentioned conventional air purifying and deodorizing device directly fills natural plant essential oil into the special polymer membrane, the natural plant essential oil has a strong diffusion effect, and its long-term In addition to lacking in sustainability, the membranes are expensive because they are made of aromatic polyamide hollow fiber membranes, and they have the problem of not being able to be provided to general customers at a low price.

The present invention was made in order to solve the above-mentioned conventional problems, and the present inventor first focused on the porosity of wood (wood flour), and studied the structure, structure, and various materials of the wood. The present invention was developed by conducting extensive research on natural plant essential oils that are compatible with wood, and focusing on utilizing the countless cells in the fiber structure unique to wood.

In other words, by injecting the necessary amount of natural plant essential oils to permeate and diffuse into the cellular tissue of the wood, and by covering the injected treated wood with other wood materials, the combined effects of the wood's hygroscopic and respiration properties can be used to improve forestry. It is possible to obtain the same wicking effect as inside, and by adding natural plant essential oil to a wooden base material such as wood flour, it is possible to take advantage of the unique porosity of wood to introduce the same type of natural plant essential oil into the cells. It is highly sustainable, inexpensive, easy to process, safe, non-polluting, and easy to handle as an end product even during factory production by allowing the yield and efficient consumption of the natural plant essential oil. The purpose of this project is to provide a method for treating wood using natural plant essential oils that have excellent properties.

Structure of the Invention (Means for Solving Problems) The method for treating wood using natural plant essential oil according to the present invention to achieve the above-mentioned object is a method for treating wood using natural plant essential oil, which is applied to a wooden base material such as wood flour or wood. It is made up of natural plant essential oils that are compatible with the wooden base material and have extremely good adhesion to cell membranes.

(Function) When obtaining an aromatic agent using wood flour, for example, based on the wood processing method using natural plant essential oil according to the present invention, wood chips are used as raw materials, and the wood chips are dried with hot air, pulverized and classified. 150 pieces of bone dry powder is obtained from the wood powder, and this powder is impregnated with natural plant essential oil. : The diameter is on the order of microns) and is embedded in the cell walls of the powder, and when used, natural plant essential oils are gradually released from the powder. The monoterpenes contained in the leaves of coniferous trees are mainly α
-Pinene, β-pinene, myrcene, camphene, limonene, etc. act on these medicinal ingredients to produce sterilizing, preservative, and aromatic effects.

(Examples) Example 1 Next, a method for treating wood using natural plant essential oil according to the present invention will be explained based on an example of using wood flour.

First, we use sawdust as the raw material, and after reducing the moisture content to 10% or less,
Particle size and moisture content are adjusted by repeatedly using a sieve and a crusher.The particle size is adjusted from 30 mesh to 150 mesh, and the moisture content is adjusted to an absolutely dry state by the heat of crushing, resulting in good eye oil properties. becomes. Use the wood flour obtained in this way. That is, the sawdust is air-dried in a hot air oven. The hot air drying at this time is instantaneous drying for 1 to 2 seconds using 60' hot air, and after drying, the material is passed through a sieve with 10 mesh meshes, and the material that passes through this is passed through a pulverizer.

The pulverizer first uses a coarse pulverizer, which finely pulverizes the sawdust, and then the mesh of this coarse pulverizer (0.71 m1
) that has a particle size of substantially 0.5111 or less is passed through a sieve with a mesh size of 30 to 40 mesh again, and the material that passes through this is passed through a pulverizer.
The wood powder is further finely pulverized and passed through a sieve having a mesh size of 80 to 150 mesh, and the dried wood flour is used.

Next, the natural plant essential oil added to the wood flour is mainly an essential oil extracted from Japanese red pine, a coniferous tree in the Pinaceae family that contains many monoterpenes, and a mixture of essential oils from other trees. In order to make it easier to inject the wood flour into the cell cavity, this natural plant essential oil is mixed in a ratio of 1 part to the wood flour, which has been pretreated with alcohol, and is injected into the pores using the porous nature of the wood flour. By penetrating the essential oil and exerting its affinity, the medicinal properties such as bactericidal and antiseptic properties of α-pinene, β-pinene, myrcene, β-phellandrene, limonene, camphuene, etc. contained in the natural plant essential oil are released. This is to obtain a powder that can be dispersed.

When using this product, store the powder impregnated with natural plant essential oil in the bag and place it in a room such as a toilet or on furniture to sterilize, preservative, and fragrance the room. It is something to do.

Example 2 Next, another example of the present invention will be described. In this example, wood flour impregnated with natural plant essential oil is formed into pellets, which are made of wood flour and glue. The core material designated by reference numeral 1 in FIG. 1 is the same as that of Example 1. 1 = 100 mesh of wood flour obtained from
The mantle material 2 that wraps the core material 1 is made of wood of 30 to 40 mesh that has been subjected to the coarse crusher and fine crusher in Example 1. Using a mixture of powder and a coagulant made of glue,
This semi-solid mantle material 2 wraps the core material 1 impregnated with the natural plant essential oil, forms it into a spherical shape, and dries it. The bag is divided into one or more pieces and placed in a predetermined bag and suspended in a suitable place such as a room to obtain sterilization, antiseptic properties, fragrance, etc.

In the above embodiments of the wood processing method using natural plant essential oils according to the present invention, wood flour and wood formed into a spherical shape are shown. After being formed into a plate shape, this plate material is injected with the natural plant essential oil.

Alternatively, wood flour is mixed with natural plant essential oil and a coagulant, and this is formed into a plate shape.

Furthermore, as shown in FIG. 2, grooves 4 are carved in the long piece of wood 3.
The groove 4 is filled with a granular treatment material 5 made of wood flour and natural plant essential oil, and the opening of the groove 4 is further closed with a joint material 6.

In some cases, it can be used as an aromatic material for indoor rooms, as an interior material (wall material) for building materials, or as a core material for festival dolls.

Furthermore, the characteristics of impregnation with natural plant essential oils do not depend on whether the wood is in the form of wood powder or solidified.

Effects of the Invention As mentioned above, the method for treating wood using natural plant essential oils according to the present invention is effective for treating wooden base materials such as wood flour and wood, which has an affinity with the wooden base materials and adheres closely to the cell walls. Since the composition contains natural plant essential oils that have extremely good properties, we use a wooden base material such as wood flour or wood to thoroughly penetrate the natural plant essential oils into the cells of the fibers, which are the main constituent parts. , strengthens the deposition of the essential oil on wall pore membranes, ultimately increases its impregnating property, and absorbs the active ingredients of natural plant essential oils, such as monoterpenes α-pinene, β-pinene, limonene, myrcene, etc. The essential oil's unique medicinal properties such as sterilization, preservatives, and fragrance can be emitted over a long period of time, and the essential oil becomes solid when impregnated with wood flour, etc., and its fluidity is reduced. It is possible to simplify the use by eliminating the
Since wood flour or wood, which is available at low cost, is used as the base material, when it is commercialized as an air freshener, it has unique effects such as being able to provide it to customers at an extremely low cost.
