Inorganic composite nanomaterial modified anti-ageing building paint and preparing process thereof

Abstract

An inorganic composite nanomaterial modified antiageing paint for building is prepared through mixing the composite nano material containing TiO2 particles coated by Si or Al with SiO2 and cerium oxide, adding solvent, assistant filler and acrylic resin, stirring, dispersing and grinding. Its advantages are high antiageing nature improved by 50-120 % and high scrab resistance, water resistance and dirt resistance.
