【発明の詳細な説明】
７本発明は木材劣化防止剤組成物及び木材劣化防止方法
に関する。DETAILED DESCRIPTION OF THE INVENTION 7. The present invention relates to a composition for preventing wood deterioration and a method for preventing wood deterioration.
家屋等の建築物に利用されるか又は利用されている木材
の劣化の要因の最も重大なものとしては白アリや＋クイ
ムシ等による食害及び各種菌の繁殖による腐朽がある。The most important factors that cause the deterioration of wood that is used or used in buildings such as houses are feeding damage caused by termites, wood beetles, etc., and decay due to the proliferation of various fungi.
しかして上記木材害虫の防除対策としては、白アリ防除
剤等を含有する油剤又は乳剤を刷毛等で被処理木材表面
に塗布したり適当な噴霧機を用いて噴霧塗布する方法が
専ら行なわれているが、之等の方法は以下の如き種々の
欠点を有しており、尚実用的方法としては満足できない
。即ちこれらの方法では、塗布する箇所が自づと制限を
受け、特に家屋等の建築物に利用されている木材ではそ
の天井裏や床下等或は壁と壁板との隙間（壁材で被覆さ
れた壁板裏面）等の処理は困難であり、また塗布操作が
煩雑で且つ作業時間が長い欠点がある。しかも２等方法
に適用される油剤、乳剤等自体比較的多量の溶剤を含有
しており、例えば油剤では上記溶剤（通常ケロシン乃至
灯油が汎用されている）が被処理木材中に浸透し、その
表面にシミ等をつくり、木材価値を著しく低減したり、
壁面等を汚染する欠点がある。However, as measures to control the above-mentioned wood pests, the method of applying an oil or emulsion containing a termite control agent etc. to the surface of the treated wood with a brush or by spraying it using an appropriate sprayer is carried out exclusively. However, these methods have various drawbacks as described below, and are still unsatisfactory as practical methods. In other words, these methods naturally limit the areas that can be coated, especially in the case of wood used in buildings such as houses, areas such as in the ceiling, under the floor, or in the gaps between walls and wallboards (where it is not covered with wall material). It is difficult to treat the back surface of a wall board (the back surface of a wall board), etc., and the coating operation is complicated and takes a long time. Moreover, the oils, emulsions, etc. used in the second method themselves contain relatively large amounts of solvents. It creates stains on the surface and significantly reduces the value of the wood.
It has the disadvantage of contaminating walls, etc.

期待できない現状にある。Furthermore, since emulsions are used after being diluted with water, the wood itself is exposed to high humidity conditions, which may actually encourage the growth of mold. In addition, as a measure against mold on wood, a method of applying oils, emulsions, etc. containing active preservative ingredients has been proposed, similar to the above method.
These also have almost the same drawbacks as above. Furthermore, in the field of insecticides, in addition to the above-mentioned oils and emulsions, air agents are also known that utilize propellants such as liquefied petroleum gas such as fluorine, dimethyl ether, silica butane, and isobutane. However, when this is used to treat the wood, a large amount of solvent and propellant gas are injected at the same time, which poses a particularly high risk of fire. In any case, there are currently no known special chemicals that can prevent wood from deteriorating.
At present, it is difficult to expect that wood pest control agents, fungicides, etc. can be applied separately to limited areas.

することを目的として鋭意研究を重ねた結果、下記特定
組成を有する組成物が、特定の噴霧方法により上記目的
に合致する木材劣化防止処理を行ない得ることを見い出
し、ここに本発明を完成するに至った。In view of the above-mentioned current situation, the present inventors have developed a method that can be easily applied to various locations where prevention of wood deterioration is required, requires extremely short working time, and does not cause contamination of the wood surface or risk of fire, etc., and has sufficient wood. As a result of extensive research with the aim of providing a new treatment means that can exhibit deterioration prevention effects, we have found that a composition having the following specific composition can be used to perform wood deterioration prevention treatment that meets the above objectives by a specific spraying method. The present invention was completed based on these findings.

剤５−２０重量％、有機溶剤０−４５重象形及び液化炭
酸ガス５−３０重量％を含有することを特徴とする木材
劣化防止剤組成物及びその利用による木材劣化防止方法
に係る。That is, the present invention provides a method for preventing wood deterioration characterized by containing 40-75% by weight of a wood pest control agent, 5-20% by weight of a preservative, 0-45 weight% of an organic solvent, and 5-30% by weight of liquefied carbon dioxide. The present invention relates to an agent composition and a method for preventing wood deterioration using the same.
本発明組成物は、上記特定組成を有することに基づいて
以下の如き極めて優れた諸効果を発揮す４−
ることかできる。The composition of the present invention can exhibit the following extremely excellent effects because it has the above-mentioned specific composition.
（１）非常に短い噴霧処理時間で、容易に施工できる。(1) Easy application with very short spraying time.
殊にその処理時間は、同様の処方の油剤（同一有効成分

れ密閉空間内に均一濃度で充分に拡散される所謂拡散効
果及び上記液化炭酸ガスの噴射蒸発による冷却効果にも
よっており、従来例を見ない卓越したものである。(2) The active ingredient is extremely effective and has an extremely excellent antiseptic effect, even in areas where it is difficult to apply known insecticides or termite control agents, such as gaps between walls and wallboards. This is not only due to the combination of wood pest control agents and preservatives, but also the so-called diffusion effect in which the liquefied carbon dioxide scum is injected in the form of fine particles by the gas pressure of the liquefied carbon dioxide scum and sufficiently diffused at a uniform concentration within the closed space, and the above liquefied carbon dioxide. It relies on the cooling effect of gas injection and evaporation, and is unprecedented.

てすみ、しかも液化炭酸ガスが上記溶剤の浸潤防止作用
をも兼ね備えているためである。該液化炭酸ガスによる
浸潤防止機構は現在尚明確でするためと考えられる。(4) Does not cause contamination of the wood surface. Although known oils, liquids, etc. cannot avoid the occurrence of stains due to the liquid infiltrating through joints, cracks, bonded parts, etc. of walls and boards, the present invention can reliably avoid such problems. This is not only because the amount of solvent in the composition of the present invention is small, but even when it is contained in a relatively large amount, the amount of the composition itself to be applied is very small. This is because it also has an infiltration prevention effect. This is thought to be because the mechanism for preventing infiltration by liquefied carbon dioxide gas is still unclear.
（５）液化炭酸ガスを噴射剤とすることにより、本発明

る。(5) By using liquefied carbon dioxide gas as the propellant, the closed space to which the composition of the present invention is applied becomes a carbon dioxide atmosphere, and its inert action can reliably prevent the risk of fire.

。The wood deterioration inhibitor of the present invention must contain 5 to 30 liters of liquefied carbon dioxide gas, along with predetermined amounts of the above-mentioned wood pest control agent, preservative, organic solvent, and other additives as necessary. shall be. This liquefied carbon dioxide scum acts as a propellant for the above-mentioned active ingredient compounds and others, and as described above, also has the effect of preventing organic solvents and the like from infiltrating into the treated wood,
Furthermore, when the composition of the present invention is applied by a specific method, it can also have a cooling effect that lowers the temperature of the applied atmosphere.
The cooling effect of the tube, together with the original preservative effect of the preservative mentioned above, makes it possible to more completely kill various types of bacteria, etc., which are the biggest cause of decay in treated wood, and also to kill termites, leaf beetles, etc. It reduces the motility of insect pests and synergizes with the control action of insecticides against wood bookworms. In particular, in the present invention, these various effects are achieved by using only about 5% by weight of liquefied carbon dioxide, and this effect is surprising. However, if the amount of liquefied carbon dioxide gas is less than 5% by weight, the above-mentioned effects will be difficult to achieve. In addition, if it exceeds 30% by weight, the pressure in the processing space will increase rapidly, causing safety issues in handling. For example, when injecting into the gap between a wall and a wall board, the pressure may completely damage the wall board. There is a ;f:o. Furthermore, there is a drawback that the miscibility of liquefied carbon dioxide and preservatives etc. deteriorates, causing separation and making uniform spraying difficult. Generally, the amount of the liquefied carbon dioxide gas is preferably in the range of about 5-15% by weight.

That is, the active ingredient compound is usually sprayed in a total amount of about 5 to 500 f per closed space II, or 177/? on the wood surface to be treated. The total amount of the active ingredient compound may be about 7 to 8 fl per spray. Spraying of such an amount of the active ingredient varies slightly depending on the internal pressure of the pressure container filled with the composition of the present invention, the diameter of the nozzle to be sprayed, etc., but it is usually carried out in a very short time of about 3 seconds. This time is about 1/1 of the time required for applying the same amount of active ingredient by brushing conventional oils or emulsions. The angle is reduced to about -14°, and from this point alone, the method of the present invention is extremely efficient and practical. Moreover, according to the above method of the present invention, the temperature inside the closed space is instantly lowered by spraying the liquefied carbon dioxide gas used as the propellant, and the temperature condition is maintained at about IO -20'C lower than normal room temperature.
The mutual effect of this cooling effect and the original effect of preventing wood deterioration due to spraying of the active ingredient compound results in an extremely excellent effect of preventing wood deterioration that has never been seen before.
