FIELD: manufacture of building materials. ^ SUBSTANCE: invention, in particular, relates to fireproofing materials based on intercalated graphite compounds and is designed for applying fireproofing coatings of outdoor and indoor surfaces of civilian- and military-destination objects, for treating industrial structures to block propagation of fire due to imparted fireproofing and high heat-insulation properties under high temperature conditions. Fireproofing composition proposed comprises 50% acrylic dispersion as binder, urea-formaldehyde resin, oxidized graphite as oxidant, pentaerythritol and Na-carboxymethylcellulose as carbonizer, titanium dioxide and calcium carbonate as filler, urea as hardener, and water, said 50% acrylic dispersion being based on copolymer of butyl acrylate, methyl methacrylate, and methacrylic acid at ratio 47:52:1 and said filler being in the form of chopped glass thread at specified proportion of constituents. ^ EFFECT: increased tensile strength and reduced variation in linear dimensions. ^ 2 tbl |
