（産業上の利用分野）
本発明は、木材、例えば造園施工に用いる間伐材等の表
面を腐食防止のため炭化させる木材の表面加工方法にに
関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for surface treatment of wood, for example, carbonizing the surface of thinned wood used in landscaping construction to prevent corrosion.
（従来の技術）
造園施工に用いられる間伐材等の木材は戸外で使用され
そのままの状態で使用すると風雨の影響等により腐食し
該木材の耐用年数を低下する。このため、従来はトーチ

表面を炭化させて該木材の腐食を防止し耐用年数を向上
させて造園施工等に使用している。(Prior Art) Wood such as thinned wood used in landscaping construction is used outdoors and if used as is, it will corrode due to the influence of wind and rain, reducing the service life of the wood. For this reason, conventionally, the surface of the wood is burnt manually using a torch lamp to carbonize the surface, thereby preventing corrosion of the wood and improving its service life, which is then used for landscaping construction.
この種の方法では、手作業によるため該トーチランプの
炎を該木材の全表面を順次網羅して燃焼させねばならい
ので該木材の表面加工に要する時間を短縮できず生産性
を向上することが困難であると共に、手作業で該木材を
加熱するため加熱時間が変動し該表面の炭化が均一とな
らない。In this type of method, since it is done manually, the flame of the torch lamp must cover the entire surface of the wood in order to burn it, so the time required for surface finishing the wood cannot be shortened and productivity cannot be improved. In addition to being difficult, since the wood is heated manually, the heating time varies and the carbonization of the surface is not uniform.
更に、該木材表面を炭化するには該木材を燃焼を開始す

木材表面に均一な炭化層を形成することができない。以
上のように木材表面を均一に炭化することができないと
炭化層の薄い部分から腐食が進行して耐用年数が低下す
るという問題がある。Furthermore, in order to carbonize the surface of the wood, the temperature at which the wood starts to burn (hereinafter referred to as the ignition point) or higher and the ambient temperature is below the temperature at which the wood spontaneously ignites (hereinafter referred to as the ignition point) is set. The wood needs to be heated. However, these ignition points and ignition points vary significantly depending on conditions such as the material and how air is mixed with the wood. It is difficult to manually control the temperature during heating and combustion to follow the fluctuations in the ignition point, and the heating time becomes uneven due to fluctuations in the moving speed of the torch lamp, making it difficult to uniformly carbonize the surface. Can not do it. Furthermore, since the surface of the wood is not smooth, it is difficult to heat the wood uniformly along the surface, making it impossible to form a uniform carbonized layer on the surface of the wood. As described above, if the surface of the wood cannot be uniformly carbonized, there is a problem in that corrosion progresses from the thinner part of the carbonized layer and the service life is reduced.
また、有孔部材等の複雑な形状のものにおいては該トー
チランプの炎をその表面形状に沿って向けることができ
ない。Further, in the case of a member having a complicated shape such as a perforated member, the flame of the torch lamp cannot be directed along the surface shape of the member.

The purpose of the present invention is to provide a method for surface treatment of wood.

It is characterized by melting a solid at a temperature and immersing the wood in this melt to carbonize its surface.

中に該木材を浸漬する。該木材は外気と接触せず内部に
吸収している酸素と結合しこの表面を燃焼の反応面とし
て燃焼を開始する。(Function) According to this process, the present invention melts the solid at a temperature above the ignition point of the wood and below the ignition point. The wood is immersed in this melt. The wood does not come into contact with the outside air, but combines with the oxygen absorbed inside, and starts burning using this surface as the reaction surface for combustion.
該反応面は時間の経過とともに木材内部に移動し内部に
向かって炭化を進行していく。その後、該木材を取り出
すが該溶融物は発火点以下の温度であるので該木材が炎
を出して燃焼することがない。The reaction surface moves into the interior of the wood over time, and carbonization progresses toward the interior. Thereafter, the wood is taken out, but since the temperature of the molten material is below the ignition point, the wood will not emit flame and burn.
（実施例） 本発明の一実施例を図面に従って以下詳細に説明する。(Example) An embodiment of the present invention will be described in detail below with reference to the drawings.

This is to carbonize the surface of red pine Y, which is 'C. The illustrated device includes a processing tank 1 that stores molten zinc
It consists of.

。Zinc X stored in the treatment tank 1 is heated by the heating device 3 to a temperature higher than its melting point and melted. The temperature of the molten zinc X is maintained by the temperature control section 2 at 460° C., which is above the ignition point of the red bean Y and below the ignition point, and completely melts the zinc X. Next, Akamatsu Y is transported above the processing tank 1. From this position, Akamatsu Y is lowered towards container L and completely immersed in molten zinc X in treatment tank 1 (shown by the chain line in the figure).
.

層を均一なものとしている。When Akamatsu Y is completely immersed in molten zinc X, contact with the outside air is cut off. At this time, the oxygen absorbed in the gaps inside the red pine Y and the cells that make up the red pine Y combine on the surface, and this surface, which is heated above the ignition point, becomes the reaction surface for combustion. Start carbonization. The reaction surface moves toward the inside of the red pine Y over time, and carbonization progresses. A carbonized layer of a predetermined thickness is formed by dipping for 10 seconds. At this time, Akamatsu Y
Even if the surface is uneven, the molten metal X flows along the surface and uniformly heats the surface, thereby making the formed carbonized layer uniform.

る。When lifting Akamatsu Y from molten zinc
Since the upper atmospheric temperature is set below the ignition point of the red pine Y, it is possible to prevent the carbonized layer of the red pine Y from emitting flames and burning out. Furthermore, the red pine Y is air-cooled above the treatment tank 1, and when the surface temperature becomes below the ignition point, carbonization ends.
その後、あかまつＹの炭化層の表面を研磨して仕上げ加

ものである。In another embodiment, the melting solid is a mixture of sodium nitrite and potassium nitrate (in a weight ratio of 5
Using the mixture X (0:50), the surface of Akamatsu Y, which is thinned wood and has an ignition point of 253 to 272°C and an ignition point of 480 to 490°C, is carbonized as in the previous example.

Thereafter, Akamatsu Y is taken out from the treatment tank 1, and the surface of the carbonized layer is polished together with the residue attached to the surface for finishing.

のではない。In the above examples, zinc and a mixture of sodium nitrite and potassium nitrate were shown as the solids to be melted, but metals or metal salts having a melting point above the ignition point and below the ignition point of the target wood may also be used. Even if a suitable wood other than red pine is used as the material, the effects of the present invention will not be hindered.
また、溶融する固体を該木材の着火点程度以上の融点を
