Abstract
ABSTRACTIn view of the problem that the poor durable and weathering performance of lightweight insulation glass bead material, glass beads composite coating could be made with nano-TiO2. These methods such as the FT-IR, SEM and the X-ray diffraction, etc were used to Study the experiment of the glass bead composite coating, and the UV-shielding property and photocatalytic property of the composite coating were analysised. The result indicated that giving 5% TiO2 could get the highest light absorption rate, and the best band of the UV-shielding property is from 470 nm to 490 nm and the absorption rate of 0.074; FT-IR test's results show that there was not any new key produced on the nano-TiO2 modified interface, the modification of nano-TiO2 by Sodium polyacrylate was just a Surface coated phenomenon. Basic mechanical properties of composite coatings experiments show that: Glass beads nano-TiO2 coating owns the durability and good resistance to weathering.
