Abstract Nano‐composite particles were prepared by different methods and we used emulsion co‐polymerization of methyl methacrylate/butyl acrylate monomers mixture in the presence of well‐dispersed silica nano particles to improve physical properties of the base polymers or add proper functions to them. The size distribution and morphology of composite latex particles characterized by dynamic laserlight scattering, Transmission Electron Microscopy and Solid Electron Microscopy. The nano‐composites formed by using two nonionic and anionic surfactants and caused to making two acrylic resins which we studied the adhesion, surface hardness, flammability, gloss brightness and organic solvent resistance of samples. This nano‐composite acrylic resins were specially improved in the flame and solvent resistance. In our test results, we found that by increasing the silica content of nano‐composites, the properties consist of adhesion and gloss decreased, if solvent and flame resistance improved properly.
