FIRE-RESISTANT COMPOSITION BASED ON EPOXY-DIANE RESIN

摘要

FIELD: chemistry; fire safety.SUBSTANCE: invention relates to production of fire-resistant compositions based on polymer binder and can be used in production of parts and articles in electrical engineering, radio engineering and other industries. Fire-resistant composition based on epoxy-diane resin contains hardener - polyethylene polyamine and filler. At that, composition, contains cross-linked polyacrylamide POLYSWELL as filler, preliminarily swollen in 20 % aqueous solution of phosphorus and boron containing oligomer DBE at weight ratio of POLYSWELL:DBE solution equal to 1:10, with following ratio of composition components, wt%: Epoxy diane resin is 100.0; polyethylene polyamine is 15.0; said filler preliminarily swollen in 20 % aqueous solution of DBE is 5.0-20.0.EFFECT: high fire resistance of epoxy-diane resin-based composites.1 cl, 2 tbl
