FIELD: chemistry.
SUBSTANCE: mixture contains carbamidoformaldehyde resin, acid hardener, surface active substance, modifying additive and water. The modifying additive is a solution of natural bischofite mineral of formula MgCl2·6H2O with density of 1.24-1.40 t/m3.
EFFECT: obtained a raw mixture provides for fluidity of the foam mass, its resistance to pathogenic flora, reduces percentage of shrinking deformation and bulk weight, increases resistance to combustion, reduces release of toxic substances.
