摘　　要：采用纳米TiO2 和纳米ZnO分别与纳米SiO2 复合,进行 2 种复合体系改性建筑外墙乳胶漆的抗老化性能比较.结果表明:纳米SiO2 与纳米TiO2 复合改性乳胶漆的抗老化性能得到明显提高,而纳米SiO2 与纳米 ZnO复合改性乳胶漆的抗老化性能的提高并不明显.对纳米TiO2、纳米ZnO、纳米SiO2 及复合粉体的紫外-可见光吸收光谱的研究表明:纳米TiO2 与纳米SiO2 复合改性乳胶漆的紫外光吸收率达到 93%以上,可以有效地发挥紫外吸收作用,从而提高其抗老化性能.Anti-aging property of exterior architectural latex coating modified by composite of nano-TiO2/SiO2 and nano-ZnO/SiO2 was studied. The experimental results show that anti-aging property of that modified by composite of nano-TiO2/SiO2 is improved much more than that modified by composite of nano-ZnO/SiO2. The UV absorption in the UV-Vis spectrum of composite of nano-TiO2/SiO2 is 93% or higher, which leads to improve anti-aging property of exterior architectural latex coating.
