FIELD: chemical technology, organic chemistry. SUBSTANCE: method involves synthesis of polyurethane foam in the presence of catalyst. A mixture of tertiary amine, its salt, carboxylic acid quaternary ammonium base of carboxylate at molar ratio (1.85-0.34):(0.12-0.89): 1 is used as a catalyst. Concentration of catalyst is 3-13 wt.- % per 100 wt.- % simple polyester or a mixture of simple polyesters. Propylene oxide or phenylglycidylic ester is used as an alkylene oxide, and acetic, formic or caprylic acid is used as a carboxylic acid, and triethylenediamine, dimethylbenzylamine or dimethylethanolamine is used as a tertiary amine in the precess of catalyst preparing. Frothing process is carried out in the form at 40 C. Product can be used for heat-insulating material making. EFFECT: increased rate of process at the composition hardening. 2 tbl |
