Study on UV-Curable Polyester Acrylate/SiO₂ Nanocomposite Resin

Abstract:

Using the hydrolysis reaction of TEOS and ethanol to prepare nano-SiO₂ sol, and grafting with silane coupling agent WD-20 to introduce double bonds to make a surface modification, the nano-SiO₂ sol mixed with the light-cured resin PEA, reactive diluents TPGDA and photoinitiators 1171 under ultrasonicto after dried concentration in vacuum oven, then the composite resin gotten was characterized through FTIR, TGA, UV-Vis and particle size analysis. The results showed as follows: the light-cured resin modified by nano-SiO₂ with WD-20 was better in dispersion and stability, and durability, abrasion resistance and other performances of the coating improved significantly which broadened the application range of light-cured resin.
