Abstract

Photocatalytic paints are polymer compounds containing the nanocatalyst that are used to break down dangerous air pollutants to low-risk compounds. In this research, photocatalytic pseudo-paint based on water-based acrylic binder with TiO2 pigment and TiO2 nanoparticles was made. In order to improvement of mechanical properties was used from water glass with different amounts in the formulation. Different amounts of TiO2 were used in this organic-inorganic binder composition and was determined the optimized formulation. Dispersion of TiO2 particles in aqueous suspensions and water glass was investigated. Tensile properties of prepared film from organic-inorganic pseudo-paint were compared with organic pseudo-paint and influence of water glass on tensile properties of pseudo-paint was investigated. The results of investigation showed that up to 10% water glass don't cause problem in film formation, whereas beyond this, in the film formation cause problem. The results showed that utilization of 5% water glass obtain the best tensile properties.
