Abstract

Abstract: The titanium dioxide encapsulated waterborne aluminum pigments were prepared by using butyl titanate as precursor.X-ray diffraction(XRD)and Fourier transformation infrared results showed the coating mechanism.The results of scanning electron microscopy,optical microscopy,multi-angle spectrometric test and corrosion resistance test proved that control pH of encapsulated media at about 6.5 in isopropyl alcohol/water medium,the diaspore on aluminum flakes surface can react with TiO2 platelet which came from hydrolysis of butyl titanate,to make the titanium dioxide sol-gel film formed on the aluminum flakes surface.

Key words: encapsulated aluminum pigments, sol-gel method, titanium dioxide thin film, corrosion resistance
