FIELD: environmental protection.
SUBSTANCE: invention relates to environmental technologies, in particular to polymer compositions for the production of sorbents. Composition contains (wt%): carbamide-formaldehyde resin – 20–35; foaming agent – SOFEKS-PO-01A – 5–10; hardener – orthophosphoric acid with the 10 % concentration – 9–14; hydrolytic lignin (cellulose fiber production waste) – 10–16; dust of electrostatic precipitators (aluminum production waste) – 8–12; water is the rest.
EFFECT: increased strength, fire resistance, sorption and protective properties of the polymeric sorbent, which is obtained from the claimed composition.
