FIELD: corrosion protection.
SUBSTANCE: corrosion-inhibiting mixture contains (A1) corrosion-inhibiting pigments, (A2) amorphous silica modified with metal ions and (A3) at least one compound of general formula I: RO-M[-O-P(O)(OH)-O-P(O)(OR1)2]3·HP(O)(OR2)2, where variable parameters and indexes have following meanings: M is central atom selected from group of Lewis acceptors, R and R1 are, independently from each other, aliphatic and R2 cycloaliphatic residues. Disclosed are also materials containing this corrosion-inhibiting mixture and use thereof as lacquer coatings for rolls.
EFFECT: increased mechanical strength and improved anticorrosion properties.
