摘要主要通过液相沉积法制备由镍离子掺杂在云母钛珠光颜料中，重点研究了沉淀剂NaOH、尿素、尿素和NaOH及用量对珠光颜料珠光效果的影响。并且通过改变包覆离子的包覆率、钛镍锑配比等一系列反应条件制备前驱体。通过XRD、湿膜制备测着色力、TG-DSC分析、热重分析、摄影生物显微镜等技术，确定制备的云母钛镍黄颜料具有较好的着色力、较均匀的表面分布、光亮的表面光泽并保证其前驱体在煅烧后可充分转化为金红石型。最终确定了制备云母钛镍黄的最优制备工艺为在尿素和NaOH沉淀剂作用下，选用Ti：Ni：Sb摩尔比为83：6：11的工艺条件，在95℃水浴中反应制备的前驱体。并在马弗炉中加热到950℃，加热过程中在200℃、350℃与550℃间保温30min以让杂质充分分解或挥发。以此制备具有良好珠光效果的云母钛镍黄颜料。63747

Title Preparation of colored ion doping pearlescent Mica titanium pigment
Abstract Mainly through the liquid phase deposition of the nickel ion doping on titania mica pearlescent pigment, focus on the effects of precipitation agent NaOH, urea, urea and NaOH and dosage of pearlescent pearlescent effect. And through the preparation of precursor change coated ion coating ratio, titanium nickel antimony ratio and a series of reaction conditions. Through XRD, the wet film preparation the tinting strength, TG-DSC analysis, thermogravimetric analysis, biological microscope photography technology, surface gloss to determine the preparation of mica titanium nickel yellow pigment with tinting strength, better than the uniform surface distribution, bright and ensure the precursor can be transformed to rutile fully in the calcined. Final preparation of mica titanium nickel yellow optimal preparation process as precipitating agent role in urea and NaOH, choose Ti:Ni:Sb molar ratio of process conditions for 83:6:11 at 95 ℃, the precursor was prepared by the reaction of the. And in a muffle furnace heated to 950 ℃, the heating process at 200 ℃, 350 ℃ and 550 ℃ between insulation 30min to let the full decomposition or volatile impurities. This preparation has a good effect of mica pearlescent titanium-nickel yellow pigment.
