COMPOSITION FOR OBTAINING OF FIREPROOF POLYURETHANE FOAM Russian patent published in 2015 - IPC C08G18/00 C08G18/08 C08G18/48 C09K21/14 

FIELD: chemistry.

SUBSTANCE: invention relates to obtaining fireproof polyurethane foam from foamed reaction mixture, which consists of mixture of polyols, polyisocyanate and fireproof additives (fire-retardants). Composition for obtaining fireproof polyurethane foam is described, which contains mixture of polyols, polyisocyanate and fireproof additives, with mixture of ammonium polyphosphate and ammonium sulphamate being applied as additives in quantity from 10 to 40 wt % of the total amount of components, and ratio of ammonium polyphosphate to ammonium sulphamate in mixture constitutes respectively from 1:2 to 7:1 weight parts.

EFFECT: obtaining polyurethane foam, which has maximal fire resistance (flammability group G-1), practically invariable density in comparison with polyurethane foam, obtained without fireproof additives.
