Adhesion and flammability of water based acrylic resins with silica nanoparticles

Abstract

In this research, the interfacial interaction between nanosilica particles increased by using emulsifiers and treated by polyethylene oxide non‐ionic surfactant. Several resins were prepared via emulsion polymerisation and were converted into water based paints. The silica content and mole fraction of acrylic monomers were altered into nanocomposite emulsions to improve the adhesion and flammability of final resins. The dynamic light scattering, transmission electron microscopy and scanning electron microscopy were used to evaluate the size distribution and morphology of silica particles. The flammability was decreased by increasing silica content of nanocomposite resins. The optimum adhesion of paints on all surfaces was on 0·4 methyl methacrylate mole fraction. The adhesion behaviour of paints on glass, ceramic and steel surface was not similar to each other by changing the silica contents and stabling copolymers mole fractions. The highest adhesion strength was on a ceramic surface with 60 g silica content.
