The present invention relates to a method for manufacturing fire-retardant wood, which provides fire retardance as well as maintains the properties of natural wood by impregnating wood with a fire-retardant resin for impregnation of the wood, and fire-retardant wood manufactured thereby. In the method for manufacturing fire-retardant wood according to the present invention, the wood is impregnated with a water soluble flame retardant, thereby manufacturing the wood, which maintains a function of controlling temperature and humidity, which is one of big advantages of the natural wood, and keeps the scent of the wood, and meets the fire retardance standard (incombustible, semi-noncombustible, fire retardant, and flameproof properties). Also, since the fire-retardant resin is attached to the micropores such as inner cavity of cells and intercellular space of the wood after drying, the chlorosis does not occur and adhesive strength does not become weak, unlike phosphorous based polymer which does not have carbon atoms, even if the fire-retardant resin remains on the surface of the wood. And the fire-retardant wood manufactured by the present invention also has significantly increased antimicrobial activity and dimensional stability.
