COMPOSITION TO PRODUCE FIRE-RETARDANT COATING Russian patent published in 2011 - IPC C04B28/26 C09D5/18 

FIELD: construction.

SUBSTANCE: composition to produce fire-retardant coating includes fire-retardant additive - carbonate of bivalent metal, amendment - diatomite or talc, hardener - portland cement and pigment. As binder it contains liquid sodium glass with module 2.6-3.2 and density of 1.200-1.230 g/cm³, modified with glycerin at the following ratio, wt %: (99.5-99.0):(0.5-1.0) accordingly, at the following ratio of components, wt %: binder - 60-70, carbonate of bivalent metal - 22-31, diatomite or talc - 4.5-6.0, portland cement - 1.0-3.5, pigment - balance.

EFFECT: development of composition for fire-retardant coating with reduced sensitivity to variation of atmospheric humidity, increased fire-resistant capacity and with no release of hazardous substances in case of coating exposure to fire, besides, fire-retardant may be of different colours by adding pigments of inorganic origin, without reduction in fire-retardant and painting properties of coating.
