酞菁蓝包覆氧化铁黄复合颜料的制备及其机理研究

Study on the preparation and mechanism of phthalocyanine blue coated with iron oxide yellow

用酞菁蓝包覆氧化铁黄制备出复合颜料,研究了酞菁蓝用量对复合颜料色彩的影响,并通过SEM、IR和UV-vis分析了复合颜料的颗粒形貌、界面相互作用和呈色机理。结果表明,随着酞菁蓝用量的增加,复合颜料的色彩可由黄绿色变为深绿色,直到酞菁蓝用量为12.62%时颜色达到饱和。光谱分析表明,酞菁蓝吸附在氧化铁黄表面,与氧化铁黄接触界面存在一定的物理化学作用,从而导致IR图谱中1608 cm-1和1708 cm-1吸收峰发生蓝移。复合颜料绿色的产生是酞菁蓝与氧化铁黄对可见光吸收作用叠加的结果。

Phthalocyanine blue and iron oxide yellow prepared complex pigment,the effect of the amount of phthaloeyanine blue to the color of complex pigment was studied,and particles morphology,surface interaction and visible region absorption spectra of complex pigment were explained via SEM,IR and UV-vis. The results show that,with the increase of the amount of phthaloeyanine blue,the color of complex pigment has turned from yellow green to dark green,and the color become saturated when the amount of phthalocyanine blue reaches 12.62%. The spectra analysis show that,phthalocyanine blue has absorbed on the surface of iron oxide yellow and occurred physico-ehemical reactions,which made the two absorption peak 1608 cm-l and 1708 cm-l blue shift in the IR spectra. The reflection of phthalocyanine blue and iron oxide yellow superposed, which brought about the green color of complex pigment.
