The results show that, with the increase of the amount of phthalocya-nine blue, the color of complex pigment has tumed from yellow green to dark green, and the color become saturated when theamount of phthalocyanine blue reaches 12.62%. The spectra analysis show that, phthalocyanine blue has absorbed on the surface ofiron oxide yellow and occurred physico-chemical reactions, which made the two absorption peak 1608 cm and 1708 cm blue shiftin the IR spectra. The reflection of phthalocyanine blue and iron oxide yellow superposed, which brought about the green color ofcomplex pigmentKey words: phthalocyanine blue; iron oxide yellow; composite pigments; surface coating technology0前金属元素,相继被禁止使用。1963年,杜邦公司首先以云母作为核心,在其表面包覆1层或多层不同的金属氧化物,成功合无机颜料具有优良的耐酸碱性和耐候性能,被广泛用于成出云母钛、云母铁等复合颜料。随后又出现了一系列以二建筑材料、涂料、塑料以及橡胶等的着色。20世纪40年代以氧化硅、碳酸钙和二氧化钛为核,用无机颜色或有机染料进行来,针对无机颜料颜色单调、色彩不够鲜艳等问题,国外开展包膜复合的新型复合颜料,从而丰富了无机颜料的品种。了用化学方法对无机颜料进行包膜以制备新型无机复合颜料本文以氧化铁黄为核心,在其表面包覆酞菁蓝金属配合的研究,出现以碱式碳酸铅、氯化亚汞、砷酸氢铅、碱式磷酸铅物制备出氧化铁基金属化合物复合颜料,研究了复合颜料的等为原料合成的多种复合珠光颜料。但其大部分因含有重性能,并探讨了其机理。实验收稿日期:2011-04-05;修订日期:2011-05-05作者简介:郭丽萍,女,1960年生,山西大同人,教授。地址:武汉理工1.1原材料大学南湖校区化学楼102实验室,E-mail;cactus(l63.com酞菁蓝,化学纯;氧化铁黄,化学纯;Nal,分析纯;乙醇,NEW BUILDING MATERIALS45
