Изобретение относится к композициям для получения теплоизоляционных материалов и может быть использовано в строительстве. Известен пенопласт, полученный на основе карбамидоформальдегидной смолы путем смешения ее со вспенивающеотверждающим агентом в струе сжатого воздуха. В изобретении предлагается дополнительно ввести в полимерный компонент жидкие лигносульфонаты, карбамид и резорцин. При этом жидкие лигносульфонаты модифицируют карбамидом до смешения их с карбамидоформальдегидной смолой.The invention relates to compositions for the production of insulating materials and can be used in construction. Known foam obtained on the basis of urea-formaldehyde resin by mixing it with foaming-curing agent in a jet of compressed air. In the invention it is proposed to additionally introduce into the polymer component liquid lignosulfonates, urea and resorcin. At the same time, liquid lignosulfonates are modified with carbamide before mixing them with a carbamide-formaldehyde resin.
