FIELD: construction engineering. ^ SUBSTANCE: invention relates to bio- and fire protection of the objects and is designed to prevent origination and development of biological damages, as well as to up fire resistance of construction objects and structures. A method is described to determine the optimum content of substance components and the substance for biological protection of construction objects, as well as for fire and biological protection of wood materials, the said substance containing component C1, i.e. ether acids of phosphorous acids, component C2, i.e. readily coking carbohydrate components, component C3, i.e. active gas developing agent, component C4, i.e. homogenising and interbonding component, wherein the content (percent by weight) of component C1, ether acids of phosphorous acids, and that of component C2, readily coking carbohydrate components are interrelated by the expression 0,053<=(alpha1C1+alpha2C2)/C1<=2,l, where alpha1 is an experimental factor selected depending upon resistance against biological damages of the object processed surface in the range of 0,051<=alpha1<=l,3, alpha2 is an experimental factor selected depending upon the object processed surface fire resistance in the range of 0,012<=alpha2<=1,1, and the content of component C1, i.e. ether acids of phosphorous acids, that of component C2, i.e. readily coking carbohydrate component and that of component C3, i.e. active gas developing agent are interrelated by the expression 0,62<=(alpha1C1+alpha2C2+betaC3)/C1<=6,l, where beta is an experimental factor selected depending upon the temperature of decomposition of the active gas developing agent in the range of 0,715<=beta<=2,2. Here, the content of component C1, i.e. ether acids of phosphorous acids, that of component C2 readily coking carbohydrate component, that of component C3, i.e. active gas developing agent and that of component C4, i.e. homogenizing and interbonding components taken together, do not exceed 100 percent by weight, and are selected from the expression l,7<=(alpha1C1+alpha2C2+betaC3+C4)/(C1+C2)<=12, where gamma is an experimental factor selected depending upon the degree of the preset homogeneity of the substance in the range of 0,93<=gamma<=1,08. here, the substance as the component C1, i.e. ether acids of phosphorous acids, contains dimethyl-phosphite, as the component C2, i.e. readily coking carbohydrate component it contains starch and/or lignine, as the component C3, i.e. active gas developing agent it contains dicarboxylic acid amides, as the component C4, i.e. homogenizing and interbonding component it contains water. ^ EFFECT: proposed substance with the optimum content of selected components improves fire and biological protection in compliance with this invention. ^ 3 cl, 3 ex, 1 tbl |
