Effect of organically modified titania and zirconia nanoparticles on characteristics, properties of coating based on acrylic emulsion polymer for outdoor applications

Abstract Effect of titania nanoparticles modified with 3 wt% [3‐(methacrylloxy)propyl]trimethoxysilane (m‐TiO 2 NPs) and zirconia (3‐glycidyloxypropyl)triethoxysilane (m‐ZrO on properties morphology acrylic emulsion polymer coating was investigated. With suitable weight ratio m‐TiO /m‐ZrO NPs, the could be improved abrasion resistance, weather durability, reflectance index (400–1400 nm) as well thermal‐oxidation stability in comparison coatings having same content single nanoparticles. The starting thermal degradation temperature filled by mixture NPs m‐ZrO approximately 10°C higher than that contained separately were used solar reflective paint. Replacement rutile TiO microparticles 1 nanoparticles, paint (SRP) water resistance cooling performance. permeability SRP reduced nearly 50%. results performance test indicated loaded (weight 1/1) replaced reduce outside chamber 11°C ambient inside 7.5°C. This novel is considered promising material for outdoor applications.
