SELF-EXTINGUISHING FOAMED POLYSTYRENE Russian patent published in 2016 - IPC C08J9/00 C08J9/22 C08J9/224 C08L25/06 C08K3/20 C08K3/26 C08K5/02

Abstract RU 2595676 C2

FIELD: chemistry.

SUBSTANCE: invention relates to self-extinguishing foamed styrene polymers. Described is self-extinguishing foamed polystyrene with low content of chlorine- or organobromine fire retardant, obtained from pre-foamed or foaming styrene polymer including, besides organohalogen fire retardant, a mixture of magnesium hydroxide and calcium carbonate 1:1-1:3 in following ratio of components, wt%: styrene polymer - 100; organohalogen fire retardant - 1.0-2.0, mixture of magnesium hydroxide and calcium carbonate - 3.0-6.0.

EFFECT: adding to polystyrene besides organochlorine combustion inhibitors a mixture of magnesium hydroxide and calcium carbonate reduces amount of acid chloride or acid bromide of carbonic acid formed during oxidative pyrolysis by twofold.
