EPOXY-DIANE RESIN BASED FIRE-RESISTANT COMPOSITION Russian patent published in 2016 - IPC C08L63/02 C08L33/26 C08J5/00 C09K21/12 

FIELD: chemistry.

SUBSTANCE: epoxy-diane resin based fire-resistant composition contains a polyethylene polyamine curing agent and filler. The filler is crosslinked polyacrylamide POLYSWELL, which first swells in an ammonia-neutralised 20% aqueous solution of phosphorus-boron-containing methacrylate (PBM) in a weight ratio POLYSWELL: neutralised PBM solution equal to 1:10. The composition contains components in the following ratio (pts. wt): epoxy-diane resin 100.0; polyethylene polyamine 15.0; the said filler, which first swells in the ammonia-neutralised 20% aqueous solution of PBM 5.0-20.0.

EFFECT: invention improves the fire-resistance of epoxy-diane resin based composites.
