HALOGEN-FREE FIRE RETARDANT Russian patent published in 2013 - IPC C08K5/00 C09K21/04 C09K21/10 C09K21/00 C08K5/3492 C08K3/32 C08K3/38 C08K3/00 

FIELD: chemistry.

SUBSTANCE: fire retardant contains at least ammonium polyphosphate(s) and/or derivatives thereof, an oligomer or polymer derivative of 1,3,5-triazine or mixtures of several such derivatives and at least one compound selected from zinc dihydroorthophosphate, zinc borate, zinc orthophosphate, zinc pyrophosphate, zinc polyphosphate, zinc hydroxystannate, zinc stannate, boron phosphate, aluminium dihydroorthophosphate, aluminium orthophosphate, aluminium metaphosphate and mixtures thereof. The fire retardant can contain pre-condensed malamine derivatives, melamine salts and adducts thereof, ethylenediamine phosphate, piperazine phosphate, perazine polyphosphate, 1,3,5-trihydroxyethylisocyanurate, 1,3,5-triglycidylisocyanurate and triallylisocyanurate. The invention also relates to a polymer material, specifically a thermoplastic elastomer containing said fire retardant in amount of 5-25 wt %, preferably 10-25 wt %. The fire retardant has low water-solubility, decomposes at higher temperatures and can be used in smaller concentrations with high fire retarding action at the same time.

EFFECT: polymer material containing the fire retardant has improved physical and chemical properties, high fire-resistance and water-resistance.
