があった。(2) A method for producing a flame-retarded wood product by causing a water-soluble inorganic material such as ammonium phosphate to act on the wood product. (3) By immersing the wooden product in the boric acid aqueous solution, or by applying or injecting the boric acid aqueous solution into the wooden product,
A method of impregnating wood products with boric acid. However, in any of the methods (1) to (3),
Since water is used as a medium for the flame-retardant and semi-incombustible treatment, the wood product is finished in a wet state (wet state), and a step of drying the wood product is required. In addition, such a water content causes dimensional deformation of the wood product, which reduces the commercial value or requires reshaping.

のである。Therefore, there has been proposed a method for producing a wood product which does not use water in the flame-retardant and semi-incombustible treatment. This method is to expose wood products such as particle board and plywood to gaseous (vapor) organoboron compounds so that the organoboron compounds penetrate inside. , The permeated organoboron compound is hydrolyzed by the water contained in the wood product, and boric acid can be adsorbed to the wood product. This boric acid imparts flame retardant and semi-incombustible performance to the wood product. It is a thing.

Molding of wood products with sufficient flame retardancy and quasi non-combustibility, because the adhesives that are used do not allow the permeation of organoboron compound gas to penetrate and cannot adsorb boric acid inside the wood products.

Further, the MFD can be manufactured by using wood fibers as a wood raw material and heating and pressing the wood fibers. Preferably, an additive such as a sizing agent or an adhesive is added to this wood fiber. Further, plywood can be manufactured by using a veneer as a wood raw material, applying an adhesive to the veneer, laminating the veneers, and heating and pressing the veneers. Further, the lightweight board or the wafer board can be manufactured by using wood chips as a raw material for wood and mixing the wood chips with a thermosetting resin or the like and subjecting the wood chips to heat and pressure molding. It is desirable to use a flame-retardant resin or a flame-retardant adhesive as the resin or adhesive used in the production of these wood products, and even if a flame-retardant is added to an ordinary resin or adhesive.

品の製造することができるものである。INDUSTRIAL APPLICABILITY As described above, according to the present invention, a wood raw material is treated with a gaseous organoboron compound to adsorb boric acid obtained by hydrolyzing the organoboron compound to the wood raw material. Boric acid treatment can be applied to a raw material or a thin wooden raw material, and boric acid can be sufficiently adsorbed. Also, since the boric acid-treated wood raw material material is collected and solidified to form a wood product, the wood product can contain a large amount of boric acid uniformly inside, and has sufficient flame retardancy and semi-incombustibility performance. It is possible to manufacture wood products.
