新型纳米钒酸铋黄色颜料的制备与性能研究
|
摘要
本文采用前驱体煅烧法和粉末煅烧法制备了纳米钒酸铋黄色颜料,并在前驱体煅烧法的基础上,添加CaCO_3、CaF_2、Al(OH)_3、MgO制备复合型钒酸铋颜料。通过X射线衍射分析(XRD)、热分析、傅立叶变换红外光谱(FT-IR)、电子显微分析等对纳米钒酸铋黄色颜料及复合型钒酸铋黄色颜料进行了表征。
以Bi(NO_3)_3·5H_2O和NH_4VO_3为原料,利用前驱体煅烧法制备了BiVO_4黄色颜料,并系统地研究了不同反应条件如反应物浓度、溶液pH值、反应温度、反应时间、煅烧温度、煅烧时间对产物的影响,同时也研究了表面活性剂的种类和剂量对产物形貌、晶型结构、色相的影响。而在粉末煅烧法中主要研究了煅烧温度、煅烧时间、研磨、矿化剂的添加等制备工艺条件;并对两种方法制备的钒酸铋黄色颜料着色性能、热稳定性能和红外吸收性能进行了比较。研究结果表明:前驱体煅烧法可制备出颜色鲜亮、粒径分布均匀、平均粒径为15-30nm具有单斜晶系白钨矿结构的钒酸铋黄色颜料,加入表面活性剂DBS可改善颜料的分散性;粉末煅烧法制备的钒酸铋黄色颜料色泽偏暗,颗粒粒径要大,平均粒径大约在40-50nm左右,分散性较差。粉末煅烧法中CaF_2、H_3BO_3矿化剂的引入提高了产物的结晶度,产物的粒径也有所减小,颜料的色相也有所变化。两种方法制备的钒酸铋黄色颜料均有较好的热稳定性,红外吸收性能没有明显变化,但着色性能不同,前驱体煅烧法制备的钒酸铋黄色颜料着色力较强。
在复合型钒酸铋颜料的研究中,通过添加CaCO_3、CaF_2、Al(OH)_3、MgO对钒酸铋黄色颜料改性,研究了不同物质及同种物质不同浓度对钒酸铋黄色颜料的晶体结构、热稳定性能、着色性能和红外吸收性能的影响。研究表明:复合型钒酸铋黄色颜料仍为单斜晶系白钨矿结构,具有比较好的热稳定性;添加不同物质可制备色相不同的钒酸铋黄色颜料,颜色可从黄相偏绿到黄相偏红,并且在添加同种物质条件下,随着添加量的增加,着色力有一定的变化。
In this paper,nano-BiVO_4 yellow pigments were prepared by the method of precursor calcined and the ceramic method.On the basis of the method of precursor calcined,composite BiVO_4 yellow pigments were prepared by doping CaCO_3,CaF_2,Al(OH)_3,MgO respectively. Additionally,nano-BiVO_4 yellow pigments and composite BiVO_4 yellow pigments were charactered by using XRD,thermal analysis technology,FT-IR and electron microscopy analysis and so on.
Using Bi(NO_3)_3·5H_2O and NH_4VO_3 as raw materials,BiVO_4 yellow pigments were prepared by the method of precursor calcined.The influence of reaction concentration,the value of pH,reaction temperature,reaction time,calcining temperature and calcining time on the crystal morphology,particle size,color and distribution were investigated,including the kind of and the dose of surfactants.Furthermore,the preparation conditions of calcining temperature,calcining time,rubbing and mineralizations which including the categories and the dose were studied the ceramic method.For this two methods,the coloring,thermal stability and infrared absorption properties of BiVO_4 yellow pigments were discussed.The results show that the monoclinic BiVO_4 yellow pigments with bright color,uniform distribution and the average size between 15nm and 30nm were obtained by the method of precursor calcined.And the dispersion of BiVO_4 yellow pigments can be improved by adding surfactant DBS.However,the monoclinic BiVO_4 yellow pigments with dim color,poor distribution and the average size between 40nm and 50nm were obtained by the ceramic method.The degree of the monoclinic BiVO_4 yellow pigments' crystallization was improved, and the particle size was smaller,and the color was changed at a certain extent by adding the mineralizations such as CaF_2 and H_3BO_3 through the ceramic method.Compared to the ceramic method,the BiVO_4 yellow pigments which were prepared by the method of precursor calcined have a brighter color.The BiVO_4 yellow pigments which were prepared by the two methods have a better thermal stability and have unconspicuous change of infrared absorption. BiVO_4 yellow pigments were modified by doping CaCO_3,CaF_2,Al(OH)_3,and MgO.The effects of different substance and substance with different concentrations on the crystal structure,thermal stability,color performance and infrared absorption of BiVO_4 yellow pigments were investigated.The researches show that composite BiVO_4 yellow pigments have a monoclinic crystal structure and a better thermal stability.And the BiVO_4 yellow pigments with different hues were prepared by doping different substance.The pigment color can be changed from yellow with a little red to yellow with a little green.Moreover,with the doping dosage increasing,the color performance has changed under the condition of doping same substance.
