Abstract: A wood chip material, especially a fireproof water resistant wood chip material, especially a fireproof water resistant wood chip material to make oriented strand boards which consists of a mixture containing 30 to 43 weight percent of wood chips, 53 to 61.9 weight percent of an aqueous solution of silicate, 2 to 5 weight percent of aluminium hydroxide, 1 to 3 weight percent of water, 0.1 to 1 weight percent of a stabilizer of the aqueous solution of silicate, and a hardener of the aqueous solution of sodium silicate in the concentration of 0.5 to 5 weight percent to the pure aqueous solution of sodium silicate providing always that the density of the aqueous solution of sodium silicate ranges from 1370 to 1400 kg/m3 and the SiO2 to NA2O molar ratio in the aqueous solution of sodium silicate ranges from 3.2 to 3.4. A method of production of a wood chip material, especially method of production of a fireproof water resistant wood chip material, especially method of production of a fireproof water resistant wood chip material to make oriented strand boards according to which, as the first step, the aluminium hydroxide is mixed with water, then wood chips are added into the mixture and everything is stirred thoroughly in such a manner that a wood chip mixture is formed, then the stabilizer of the aqueous solution of sodium silicate is added in the aqueous solution of silicate and after that the hardener of the aqueous solution of sodium silicate is admixed in this solution. Then the solution is stirred for 1 to 10 minutes until a binding solution is formed. Then the wood chip mixture is poured, at continuous stirring, in the binding solution and everything is stirred thoroughly again. Then the resulting mixture is poured in the place of application.
