Photochromic Inhibition of Dyed Veneer Covered with Modified Transparent Film
Abstract:
The overlying free film method was used to study the nanoTiO2 and UV absorbing agent modified water-borne acrylic varnish and polyurethane varnish of dyed veneer photochromic suppression effectiveness, using infrared spectrum analyzed the photochromic behavior of dyed veneer under different coated condition. Results showed that dyed veneer covered with UV modification film has the best light restraint, film modified by nanoTiO2 takes second place, and unmodified film worst. Photochromic inhibitory rate of UV modified polyurethane and acrylic paint film were 56.37% and 33.59% respectively, the rate of nanoTiO2 was 15.85% and 17.24%.
