【摘要】 本文运用各种仪器和测试方法,对α-和β-铜酞菁颜料的晶体性质、晶相调整和颜料化方法进行了研究.发现不同晶相铜酞菁色光的差别本质在于晶体中的分子堆积形式不同.本文考察了酸溶法制α-铜酞菁颜料中稀释温度与颜料质量的关系.并找到了一些不使α-铜酞菁转相的有机溶剂,用这类溶剂回流处理α-铜酞菁颜料能提高颜料的质量.本文还探索了国外新的β-铜酞菁颜料化方法——晶种法.更多还原

【Abstract】 The crystal phase adjustment and the after treatment of Copper Phthal-ocyanine pigments were studied experimentally by means of DTA, BET, X-ray diffraction, electro-microscopy, infra-red spectroscopy, trichromatic observation, wetting angle determination, particle size evaluation, etc. It was found that the color difference between the α-and β-Copper Phthalocyanine was mainly due to the different manners of the piling-up of the primary pigment crystals.The influence of dilution temperature on the properties of α-Copper Phthalocyanine by the sulphuric acid pasting process was studied. A series of organic solvents which did not convert α-to the β-Copper Phthalocyanine was listed. The pigment properties of β-Copper Phthalocyanine after re-fluxing with these solvents were found to be materially improved. A crystal seeding method for the preparation of β-Copper Phthalocyanine from α-Cop-per Phthalocyanine was demonstrated to be superior to the commercial kneading method, on account of less energy consumption.更多还原
