溶胶／凝胶法制备改性彩色银浆油墨的研究

摘要

Cibacron Red 4G-E pigments or pigments phthalocyanine blue are deposited on the sur-face of aluminum powder first,then tetramethyl orthosilicate (TMOS)and methyl trimethoxysi-lane (MTES)are chosen as precursors to form an inorganic film or inorganic/organic hybrid film in the presence of catalytic ammonia through modified sol-gel method in this paper.Hence the colored aluminum pigments and the optimized preparation conditions of magenta silver ink and blue silver ink are obtained.By the characterization of scanning electron microscopy (SEM),X-ray energy dispersive spectroscopy (EDS)and Color Difference analysis of the samples prepared under the optimized conditions,the results show that the two colored aluminum pigments ob-tained in this experiment present bright color,smooth and dense surface,the acquired coloring silver ink comply with printing standards,and the effect of two different coloring methods are discussed respectively.%本文采用改进的溶胶/凝胶法，先将颜料Cibacron Red 4G-E或酞菁蓝沉积在铝粉表面，再以正硅酸甲酯（TMOS）和甲基三乙氧基硅烷（MTES）为前驱体，在氨水的催化作用下于铝粉表面包覆一层无机膜层或无机/有机杂化膜层实现着色，并得出制备品红色银浆油墨和蓝色银浆油墨的最佳工艺条件。通过扫描电镜（SEM）、X射线能谱仪（EDS）、色差分析对最佳工艺条件下制备的样品进行分析与表征，结果表明本实验得到的两种着色铝粉色泽鲜艳、表面包覆致密完整，调配而成的彩色银浆油墨符合印刷标准，并分别对两种有机颜料采用不同着色方法的着色效果进行了探讨。
