FIELD: chemistry.
SUBSTANCE: invention relates to thermoreactive polymers. Described is composite, which includes: formaldehyde-free binding substance, which includes polyvinyl alcohol and one or more linking agents for hydroxyl polymer, selected from sodium trimethaphosphate, sodium trimethaphosphate/sodium tripolyphosphate and phosphorus oxychloride, polyamide/epichlorohydrin linking agents, cyclic amide condensates, and their combinations, in which polyvinyl alcohol and one or more linking agents for hydroxyl polymer are free of aldehydes; and substrate of mineral wool, processed with water solution of binding substance. Method of obtaining claimed composite is described.
EFFECT: reducing of toxicity.
