FIELD: heat-insulation materials.
SUBSTANCE: invention, in particular, relates to carbamide foam plastics and can find use in layered building structures. Composition contains, wt parts: urea-formaldehyde resin 100, alkylbenzenesulfonic acid 1.8-2, 50% 1-oxyethylidenediphosphonic acid solution 4.0-4.4, swelled perlite sand 1-4, and water 60-80.
EFFECT: reduced linear shrinkage of heat-insulation material and reduced consumption of curing catalyst for urea-formaldehyde resin.
