摘要 利用透射电镜(TEM)对纳米二氧化钛的形貌和粒度进行分析后,将纳米二氧化钛制成乳胶漆、汽车漆、家具漆和防腐漆,对其进行耐候性、随角异色等性能分析。结果表明,金红石纳米二氧化钛可大幅度提高乳胶漆的耐候性、耐水性、耐碱性和耐洗刷性能,可提高家具漆和防腐漆的耐候性;纳米二氧化钛和铝粉配合制成的汽车漆具有随角异色效果,二氧化钛的粒度对其随角异色性能有很大影响,平均粒径为280 nm的普通颜料钛白改性铝粉漆无随角异色效果,平均粒径为35 nm的纳米二氧化钛改性铝粉漆有显著的随角异色效果,并且随纳米二氧化钛加量的增加,其不同角度的颜色差异增大。 Based on the morphology and particle size analyses of nano-TiO_(2) by transmission electron microscopy(TEM), the nano-TiO_(2) was respectively made into latex paint, automobile paint, furniture paint and anticorrosion paint to investigate the weather resistance and optically variable property. The results show that the rutile nano-TiO_(2) can greatly improve the weather resistance, water resistance, alkali resistance and washing resistance of latex paint, and can also improve the weather resistance of furniture paint and anticorrosive paint.The automobile paint containing nano-TiO_(2) and aluminum powder has optically variable property, and the particle size of TiO_(2) has a great influence on the optically variable property. The aluminum paint modified by the ordinary TiO_(2) with an average particle size of 280 nm has no optically variable effect, while it has significant optically variable property with 35 nm TiO_(2) as the modifier. And the color difference from various angles increases with increase in the addition of the nano-TiO_(2).
