In the detailed description, the present invention correctly indicates applications and application ranges. Further, in the antiseptic treatment material and composition described in detail in this description, the type, use, shape, form, etc. of the treated wood are not limited.
[0006]
In claim 1 of the present invention, air-dried cedar wood is introduced into a water tank in which an aqueous solution obtained by diluting a tannins persimmon undiluted solution 10 times with water up to 80 ° C., and air in the wood becomes air bubbles and above the liquid. After the appearance and termination, the input wood was taken out and again put into the aqueous solution at room temperature to be immersed in the wood.
[0007]
The above-mentioned wood preservative treatment method is a method using a warm / cold bath method, and this method is an optimum method that utilizes the fact that the used tannins of persimmon astringents are not altered by heating. Moreover, you may use it similarly with a persimmon astringent stock solution.
[0008]
Cut the cedar wood treated by the hot and cold bath method, and contact each part with iron dioxide that turns black when it comes into contact with the tannins of persimmons on the sapwood part and the core part at the center of the cedar. As a result of confirming that the color changed to black, it became clear that the tannins of persimmons were sufficiently immersed in the wood.
[0009]
The cedar obtained by the above method becomes an old soft red color, and it becomes possible to provide a new material for the interior and exterior of the building. One of the features of the present invention is that tannin black is obtained by making the water tank used for production into a steel plate, and it becomes a light black cedar by infiltrating into the cedar, resulting in the finish of a famous cedar tone. It is.
