Abstract
Disclosed is an accelerated petrifaction process of lignocellulose materials, including the step of impregnating with an aqueous solution an alkaline hydroxide and a soluble silicate, under pH conditions that permits its partial neutralization and insolubilization of the salts in situ in the interior of the lignocellulose material by the action of acid groups present in the lignocellulose material and the acidic action of carbon dioxide present in the surrounding air.
Claims19
Accelerated petrifaction process of lignocellulose materials to increase its characteristics of resistance to fire, termites and fungi as well as to improve its physical-mechanical properties, CHARACTERIZED by being realized in only one process step, which consists in the impregnation with an aqueous solution of an alkaline hydroxide and a soluble silicate, under pH conditions that permits its subsequent partial neutralization and the consequent insolublization of the salts “in situ” in the interior of the lignocellulose material by the action of acid groups present in the lignocellulose material and the acidic action of carbon dioxide present in the surrounding air.
