文摘内容
Bamboo deterioration caused by light becomes a significant problem as application of bamboo extends from indoor to outdoor.The color and roughness of bamboo are two important exterior performances.This study focused on UV resistant nano composites coatings for exterior use and what aimed to find a formulation which could enhance the durability of bamboo.Four kinds of film-forming materials and four kinds of nano particles were used to improve bamboo exterior performance.The color and roughness of nano composites coatings were measured during accelerated weathering.Artificial aging time was 174 h at the temperature of 50 ℃.The experiment showed nanocomposites coatings had significant improvement in UV-shielding and nearly all the samples presented a darkening tendency in ΔL* and increasing tendency in Δa*,ΔE* and ΔRa.The orthogonal experiment obtained the least change in color and Ra which could be achieved with nano composites coating made by melamine resin and TiO2 when a* was considered as an important index.Film-forming material was the only factor which had significant influence on color and roughness when a* was not considered as important index,then melamine resin was the best choice.
