ABSTRACT

A one-stage technique for the synthesis and modification of nanosized corrosion-inhibiting pigments based on zinc phosphate for the under coatings with a good affinity to the organic phase has been developed. It was shown, that the acrylic monomers can be used as the effective modifiers of the zinc phosphate nanoplates surface. The optimal concentration of modifying agent in the reactive medium is established. With the use of the electrochemical impedance spectroscopy the anticorrosion activity of the obtained pigment in undercoating composition was investigated. It was determined, that at the addition of 1% mass of the nanosized zinc phosphate the efficiency of the undercoating is higher in comparison with the sample containing of 5% mass of the Novinox ® PZ02 pigment.
