Paper Title
Decorative Nanocomposite Paint as an Insulator for External Coatings of Buildings

The purpose of this research is to produce nanocomposite coatings of nanoparticles and exterior paints used in the building to reduce the surface warming and contribute to energy conservation. For this purpose, nanocomposite samples with different percentages (1, 3 and 5%) were prepared by using clay nanoparticles and urethane resins. At first the nanoclay were dispersed in polymeric matrix by ultrasound irradiation (20 to 30 minutes) and mechanical mixing (1 hour). Then the samples were coated on a galvanized surface with a thickness of 30 microns. The gloss test for samples was done. Then, the morphology of nanocomposite was studied by scanning electron microscopy. Thermal effect of the coatings was evaluated by thermograph camera. The results showed that according to amount of nanoparticles in urethane matrix, the gloss and surface thermal temperature of nanocomposites decreased.
