FIELD: chemistry.
SUBSTANCE: present invention relates to a double-component coating composition (2C), as well as a coated article, a method of making a coated article and use of material which contains a phosphorus-containing polyol as a fireproof material in the disclosed composition. The composition contains: (a) first component containing isocyanate, wherein said isocyanate contains a prepolymer having isocyanate functional groups formed from a reaction mixture containing isocyanate and a material containing a phosphorus-containing polyol with the equivalent ratio of isocyanate groups to hydroxyl groups greater than 1 and the phosphorus-containing polyol which acts as fireproof material is (i) a product of reaction of the source phosphorus-containing polyol, selected from polyphosphate polyols, polyphosphite polyols, polyphosphonate polyols and mixtures thereof and compounds having epoxy functional groups; or (and) a product of reaction of a phosphorus-containing acid, a compound having epoxy functional groups and, optionally, a phosphorus-containing polyol; and (b) a second component containing a polyamine, wherein the first and second components are stored separately and form polyurea after mixing and the composition further contains an additional fireproof material which is added to the first and/or second component and is selected from graphite, halogenated phosphates, phosphates without a halogen, tris(2-chloropropyl)phosphate, tris(2,3-dibromopropyl)phosphate, tris(1,3-dichloropropyl)phosphate, diammonium phosphate, powdered or pyrogenic silicon dioxide, sheet silicates, aluminium hydroxide, bromated fire-retardants, halogenated aromatic compounds, antimony oxide, aluminium oxide trihydrate, metal borates, zinc borate, barium metaborate pentahydrate, ester phosphates, polyvinyl chloride, melamine cyanurate, melamine phosphates, polymelamine phosphates, melamine pyrophosphates, polylmelamine pyrophosphates, melamine borate, other melamine derivatives and mixtures of compounds.
EFFECT: obtaining a double-component coating composition, having improved fire-resistance and heat-resistance.
