Abstract
In this paper, a specific emulsion polymerization of acrylic monomers, in the presence of silica particles, is developed to improve the physical properties of the base polymers and add proper functions to them. With this technique, nanocomposites were made by using two types of nonionic and anionic surfactants. To apply resins as water-based paints, the properties of two nanocomposite latexes were measured and the results were reported. The basic properties of nanocomposite acrylic paints, adhesion, surface hardness, wet scrub, scratch, flammability, gloss and solvent resistance, were evaluated and compared with acrylic paint before adding silica nanoparticles. The nanocomposite acrylic paints especially showed improvement in the reduction of flammability, organic raw materials content, wet scrub resistance, hardness and organic solvents resistance.
Our team would like to acknowledge the contributions and assistance of all of our colleagues. This research and development was supported by Amirkabir University of Technology.
