FIELD: chemistry of polymers. SUBSTANCE: present invention describes multilayer polymeric material with fireproof face layer based on plasticized suspension or emulsion polyvinyl chloride with additives of antipyrene, stabilizers and phosphorus-containing plasticizer. Layer that follows face layer comprises, wt. %: emulsion polyvinyl chloride or perchlorovinyl resin, 100; plasticizer, 30-60; antipyrene, 10-30; and compound selected from group consisting of azodicarboxylic acid, $$$-azobis-(isobutyronitrile) $$$-dinitrosopentamethylene tetramine (n-hydroazinosulphonylcarbamic acid methyl ester, diazoaminobenzene, maleic acid and malonic acid, 10-30. Material is glued onto inside layer mode of reinforced or other non-reinforced material or onto the surface of the object to be protected. Said material high fireproof and heatproof properties when affected by thermal streams and hot rubber-like agents and is used many times. EFFECT: improved properties of the multilayer fireproof polymeric material. 2 tbl
