Modification of the TiO2 and preparation of TiO2 / polyacrylate core shell nano composite particles through emulsion polymerization

Waterborne paints are primarily based on acrylic emulsions and dramatically have lower volatile organic compounds emission into the environment. Nowadays, it is well knownthat nanosize latexes are essential premise for the formation of high-quality films. In addition, nano-sized structures allowincreasing the coating density, thickness, tensile strength, Young´s modulus, and wear resistance [1]. This work describes polymerization of the reinforced acrylicresins based on nano-TiO2 modified with glycidyl methacrylate (GMA) as the core and methylmetacrylate(MMA) and buthylacrylate (BA) as the co-monomers to provide a shell onto the core. Presence of modified TiO2 in the polymeric structure of the acrylic resin for using in waterborne traffic paints might improve thermal and mechanical properties of the coating, due to the fine dispersion in the polymeric matrix [2].
