METHOD OF PRODUCING HEAT-RESISTANT NON-COMBUSTIBLE EPOXY BINDER BASED ON CYCLOPHOSPHAZENES Russian patent published in 2016 - IPC C08G59/14 C08K5/5399 C09K21/00 C08L63/02 

FIELD: chemistry.

SUBSTANCE: invention relates to fire-resistant modified epoxy binder. Disclosed is method of producing heat-resistant non-combustible epoxy binder based on cyclophosphazenes by sequential processing by phenolates of halogen-and hydroxy-containing phenols hexsachlorcyclotrifosfazene (P₃N₃Cl₆) or its mixture with higher cyclophosphazenes with subsequent conversion of hydroxyl groups in epoxy by reaction with epichlorohydrin, wherein the epoxy binder includes functional arylooxyohosphazenes of structure P_nN_nR_2n, where n is an integer from 3 to 8, and R are radicals of halogen- and hydroxy-containing phenols and phenolates is obtained by means of sodium ethylate peralkoholize of corresponding phenols.

EFFECT: produced by proposed way binder can be used as matrix of polymer composite materials and to increase their fire resistance.
