摘要
利用紫外可见光谱、SEM、BET、CPS等手段对几种汽车漆用金红石型纳米TiO2进行了详细的分析,在此基础上以纳米TiO2 PGNR-508为原料,将纳米TiO2与铝银浆配合制成随角异色汽车漆,并对其耐候性和随角异色性能进行了分析。结果表明纳米二氧化钛PGNR-508具有柱状结构,径向约10 nm,轴向约50~100 nm,其粒度分布较均匀,对紫外线具有很强的屏蔽性能,纳米TiO2改性后汽车面漆具有明显的随角异色效应,同时能大幅度提高汽车面漆耐候性。
Several kinds of rutile nano-TiO2 used in automotive paint were analyzed by UV-Vis spectra,SEM,BET and CPS.On the basis of characterizations,rutile nano-TiO2 PGNR-508 with aluminium paste was used as the raw materials to prepare the optically variable automotive paint,and the weather resistance and optically variable properties of the paint were analyzed.The results show that the nano-TiO2 PGNR-508 has a cylindrical structure with about 10 nm of diameter and about 50~100 nm of axial direction size.It has a uniform particle size distribution and strong shielding to ultraviolet radiation.The modification of nano-TiO2 can give the automobile paint an optically variable effect obviously and can improve the weather resistance of the paint significantly.
