FIRE-RESISTANT COMPOSITION BASED ON EPOXY-DIANE RESIN Russian patent published in 2016 - IPC C08L63/02 C08L33/26 C09K21/06 C09K21/12 

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 ammonia-neutralised 20 % aqueous solution of phosphorus and boron containing oligomer DBE at weight ratio of POLYSWELL:neutralised 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 ammonia-neutralised 20 % aqueous solution of DBE is 5.0-20.0.

EFFECT: high fire resistance of epoxy-diane resin-based composites.
