FIELD: chemistry.
SUBSTANCE: invention relates to a foaming agent containing a compound of an organic amine salt of formula (I) or a mixture of compounds of organic amine salts of formula (I). Formula (I): An-[Bm+]p (I), where An- is an anion - source of CO2 , having -n valence, where n = 1, 2 or 3, Bm+ is or contains an ammonium ion with valence +1 and/or one or more organic amine (B) cations, in which each cation (B) has -+NR3R4H group and/or a group -+NR3H- in an amount of m, where m = 1–5, 0 < p ≤ (n/m), and where organic amine (B) is an organic amino compound (B) having from 2 to 50 carbon atoms. Value An- is as specified in the claim. Compound of an organic amine salt of general formula (I) or a mixture of compounds of an organic amine salt of formula (I) contains 22–96 wt. % monoamino alcohol salts and diamine alcohol salts based on the total weight of the compound of the organic amine salt of formula (I) or a mixture of compounds. Content of water in the foaming agent ranges from more than 0 to 40 wt. %. Also disclosed are methods of producing a foaming agent, a foaming composition for producing foamed polyurethane and foamed polyurethane material.
EFFECT: disclosed foaming agent can be uniformly dispersed in a foaming composition for uniform foaming, and cells in foamed polyurethane have uniform distribution and uniform size of cells.
