摘要
矿物颜料是传统绘画的物质基础,青金石颜料的应用历史源远流长。为研究高能球磨对青金石结构和颜料性能的影响,使用行星式球磨机处理原料,通过扫描电镜测试、透射电镜测试、激光粒度分析、BET分析、X射线衍射测试、X射线光电子能谱测试对样品进行分析和表征,以硅橡胶基底法制备颜料样品并使用分光色度计进行色差分析。研究结果表明,球磨后,颗粒的物质组成不变,表面的层状沟纹形貌被破坏,粒度和孔径减小,粒径分布变窄,比表面积和孔容增加,结晶度降低。球磨后颜料的亮度和反射率上升,粒度变化是其主要影响因素。在一定研磨时间内粒度变小使处在长波段的红光的反射受到干扰,颗粒在a*轴色品上产生由红色向绿色漂移的呈色效果;在一定研磨时间后颗粒结晶度变小使蓝紫波段可见光的反射受到削弱,颗粒在b*轴色品上产生由蓝色向黄色漂移的呈色效果。
Mineral pigment is the material basis of traditional paintings. Lapis lazuli pigment has long been used in historical paints. In order to study the effect of ball milling on the structure and pigment properties of the lapis lazuli,which was processed by using a planetary ball mill, then samples of processed lapis lazuli material were analyzed and characterized by using scanning electron microscope, transmission electron microscope, laser particle size analyzer, BET analyzer, X-ray diffractometer, and X-ray photoelectron spectroscopy. Color difference analysis was performed on the silica gel-based pigment samples using a spectrocolorimeter. The results show that components of particles of the milled samples are unchanged, but the morphology of the surface was destroyed surface lamellar furrow morphology of them was destroyed comparing to particles of the raw material. The particle size, pore size, particle size distribution range, and crystallinity of the milled samples are decreased while the specific surface area and pore volume of particles of the milled samples are increased comparing to the raw material. The brightness and reflectivity of the milled pigment samples are increased, mainly due to the change of particle size. The reduction of particle size of the milled samples within a certain milling time has interfered with the reflection of red light in the long wavelength range, resulting in the chromaticity changing from red to green on the a* axis of particle, while after a certain long milling time, the reduction of crystallinity of the milled samples has weaken the reflection of visible light in blue-violet wavelength range, resulting in the chromaticity changes from blue to yellow on the b* axis of particle.
