Abstract

In order to enhance the corrosion resistance and resin consistence of aluminum pigments, SiO2 and polyacrylate were used to encapsulate the pigments by means of the sol-gel method and the in-situ polymerization, respectively. Then, the mechanism of encapsulation was analyzed, and the surface morphology and structure of the encapsulated pigments were characterized by means of FT-IR, XPS and ESEM. Moreover, the influences of encap- sulating conditions on the properties of the coating films containing encapsulated aluminum pigments were investigated. The results show that, with a monomer dosage of 0. 7 g, the aluminum pigments encapsulated at 85 ℃ for 4 - 5 h is of significantly-improved dispersibility and adhesion, which enables the coating film to possess good appearance, high glossiness, and strong acid resistance.

Key words： aluminum pigment; polyacrylate; silicon dioxide; in-situ polymerization; encapsulation; adhesion
