- the present invention relates to a method for producing a functional wood having at least one of various functions such as insect repellent, fungicide, water repellent, antiseptic, flame retardant, coloring or invariant color. . Background art
- wood is usually put in a can for injection, and the inside of the can is evacuated and contained in the wood. It is common practice to exhaust the air that has been pumped out, make it easier to impregnate the chemical, then inject the chemical into the can and allow the chemical to penetrate the wood under pressurized conditions. " Further, as the steaming method, for example, as described in the invention described in claim 4 of Japanese Patent Application Laid-Open No. 2001-31510, “methyl isothiosia in a processing chamber containing wood is used.
- the present invention has been made in view of the above-mentioned actual condition of wood, and its object is to provide various functions such as insect repellent, fungicide, water repellent, antiseptic, flame retardant, coloring or invariant color function. Or to easily produce functional wood with at least one function.
- means adopted by the invention described in claim 1 will be described with reference numerals used in the "Best Mode for Carrying Out the Invention" described later. As shown in FIGS. 1 and 2,
- an injection hole 20 is formed in at least the sapwood section 12 of the tree 10 and insect repellent, fungicide, and water repellent are formed in the injection hole 20.
- insect repellent, fungicide, and water repellent are formed in the injection hole 20.
- this standing tree 10 was cut down, dried, and cut into the specified wood.
- the production method according to claim 1 is performed to impart various functions to wood such as insect repellent, fungicide, water repellent, antiseptic, flame retardant, coloring or invariant color function.
- Various artificial operations after sawing are performed using the biological functions of the standing trees 10 as they are.
- Typical tree trunks used as timber have the structure and function shown schematically in Figure 3.
- the trunk of this tree (standing tree 10) transports water and nutrients taken in from the soil by roots 15 to the leaves, and transports the photosynthetic substances made from the leaves to each part of the standing tree 10. It is also a conducting organ.
- the trunk of the standing tree 10 is a supporting organ for supporting the leaves that are photosynthetic sites to sufficiently utilize sunlight, and is also a storage organ for storing a part of photosynthetic substances and various metabolic products. is there.
- Most of the trunks of such trees are xylem cylinders with a small amount of "pulp" in the center
- the xylem column is wrapped in a thin layer of meristem, called the vascular cambium, and is wrapped outside with bark 14.
- the xylem is divided into a core material 11 at the center and a sapwood 12 around the core 11, and the sapwood 12 starts from the root 15. It has the function of conducting upwards toward the leaves, the mechanical support function, and the storage function described above.
- the core part 11 is a part that was once the sap part 12, and is a part that plays a mechanical supporting function.
- the bark 14 is divided into an inner bark layer consisting of the phloem, which has a living function, and an outer bark layer, which has lost its vital function. It has a conduction function of transporting to a section and a storage function.
- the outer bark functions to protect the tree from high and low temperatures, dryness, and mechanical damage to the outside world.
- the production method according to the present invention is characterized in that the sapwood part 12 and the bark 14 of the tree generally have an upward conduction function from the root 15 to the leaf, a storage function, and
- the biological functions inherent in Tachiki 10 itself such as the conduction and storage functions of transporting the produced photosynthetic substance to various parts
- the chemicals can be placed without the use of mechanical equipment. It is made to penetrate into 10 and store.
- the method of the present invention must be applied before cutting the standing tree 10 to be wood. This is because, after cutting the standing tree 10, the conduction function and storage function inherent to the standing tree 10 cannot be used.
- the sapwood portion 12 is a portion in which the standing tree 10 has a function of conducting and storing life, so that the sapwood portion 12 passes through the inside of the sapwood portion 12. Injecting the chemical directly into the sapwood section 12 through the injection hole 20 that replaces the moisture and nutrients from the root 15 sucked up by the leaf transpiration function This is because they can be sucked up.
- the good thing of forming the injection hole 20 in the sapwood part 12 is that it is naturally formed through the bark 14, so that the conduction function and storage function of the bark 14 can be used. Is natural.
- the injection hole 20 may be formed not only in the sapwood portion 12 but also in the root 15. Then, in the injection hole 20 formed as described above, an agent that exerts an insect repellent, fungicide, water repellent, antiseptic, flame retardant, coloring or invariant color function is added at least 1 time from the time of cutting the tree 10. It is supplied from the day before. In other words, it is necessary to inject this chemical before the felling of the standing tree 10, because the conduction function and the storage function that the standing tree 10 originally has are effectively used. To use it, otherwise it makes no sense.
- the injection period differs depending on the tree species, and is generally short in conifers with few sapwoods 12 and long in hardwoods with many sapwoods 12.
- the medicine is injected into the sapwood part 12 by utilizing the water or nutrient sucking power of the tree 10. Therefore, the standing tree 10 has a function intrinsic to the function of the drug.
- the trees 10 are cut down, dried, and cut into predetermined wood.
- the sapwood 12 be exposed on the surface.
- the drug injected by the above method has penetrated into the sapwood portion 12, and the drug is present in the sapwood portion 12 on the surface.
