FIRE-RESISTANT MODIFIED WOOD AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a fire-resistant modified wood having enhanced noncombustibility or flame resistance, capable of reducing costs and contributing to environmental preservation with use of shells as waste substance; and manufacturing method thereof.SOLUTION: The fire-resistant modified wood is manufactured by performing: a fine pulverizing step S1 of fine pulverizing shells; a solution preparation step S2 of dispersing fine pulverized shells obtained in the fine pulverizing step S1 in a solvent so as to prepare a solution having a predetermined concentration; an immersion step S3 of immersing a wood in the solution obtained in the solution preparation step S2 under reduced pressure, for impregnation of the cells of wood and cell interstices inside the wood with the solution; and a drying step S4 of drying the wood obtained in the immersion step S3.
