FIELD: construction. ^ SUBSTANCE: method of construction material treatment with boron and construction materials treated with boron. The method of construction material treatment with boron involves a stage of injection of a copper- and boron-containing compound in the process of production of composite construction materials based on cellulose-containing particles and adhesive material. As the copper- and boron-containing compound, a copper/borate complex is used, which is readily soluble in water, not adversely affecting the mechanical properties of the adhesive material used, and obtained by mixing powdered copper oxide with powdered boron compound in the form of Na2B8O13 . 4H2O or Na2B8O13 . 4H2O and H3BO3, subsequent heating of the resulting mixture until melting and homogenisation, forming, annealing at 300-550°C, and milling to a finely dispersed state. ^ EFFECT: expansion of nomenclature of glues and adhesive materials used; decreased leaching and enhanced fungicidal properties. ^ 2 cl, 2 dwg, 6 tbl |
