METHOD OF OBTAINING FIRE-RETARDANT INTUMESCENT COMPOSITION Russian patent published in 2013 - IPC C09D5/18 B82B3/00 C09D133/00 C09D5/02 

FIELD: chemistry.

SUBSTANCE: invention relates fire-retardant intumescent compositions used to reduce flammability and improve fire-resistance of materials and structures. The method producing a fire-retardant intumescent composition based on polymer binder, ammonium phosphate, pentaerythritol, melamine and target additives for stabilisation and decoration involves further addition to the composition of 3.0-7.0 wt % organosilicon polymers having backbone chains consisting of alternating silicon and oxygen atoms and 0.02-0.07 wt % C₆₀ fullerene.

EFFECT: obtaining a coating having different strength properties: retention of adhesion to the protected surface at high temperatures, elasticity of the formed coked cellular material.
