FIELD: chemistry.
SUBSTANCE: invention relates to 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- – anion – source of CO2, having -n valency, where n=1, 2 or 3, Bm+ is or contains an ammonium ion with a valence of +1 and/or one or more organic amine cations (B), in which each cation (B) has a group -+NR3R4H and/or group -+NR3H- in amount of m, where m=1–5, 0<p≤(n/m), and where the organic amine (B) is an organic amine compound (B) having from 2 to 50 carbon atoms. Values of An- such 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 25–95 wt% monoamino alcohol salts and a salt of diamine alcohols 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 is >0 wt% to 40 wt%. Also disclosed are methods of producing a foaming agent, a foaming composition for producing foamed polyurethane and foamed polyurethane material.
EFFECT: proposed 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.
