Název v původním jazyce

Anticorrosion properties of glassy-crystalline borophosphates in water-borne coating system

Popis výsledku v původním jazyce

Anticorrosion pigments on the basis of glassy and crystalline borophosphates formulated as 20CaO-30ZnO-20B2O3-30P2O5 and 20SrO-30ZnO-20B2O3-30P2O5 were synthesized. The prepared pigments were characterized by means of X-ray diffraction and their physical-chemical properties were determined. The synthesized pigments were used to prepare water-borne styrene-acrylate coatings with a 10% anticorrosion pigment content. The coatings underwent corrosion tests in a humid environment with SO2 content and a testin a salt mist environment. The corrosion tests results were compared with industrially produced pigments. As the glassy phase reduces the anticorrosion efficiency of the coatings with the Sr-Zn borophosphate content decreases too. In case of the Ca-Zn borophosphates, the maximum anticorrosion efficiency was detected with regard to a pigment containing 75 wt% of the glassy phase.
