摘要
以十二烷基苯磺酸钠(SDBS)作为结构导向剂,液相法制备钒酸铋黄色颜料纳米粉体,探究了SDBS对钒酸铋颜料形貌结构、物相以及色度值的影响.结果表明,SDBS可以在钒酸铋制备过程中促进钒酸铋(121)晶面的生长,同时,有效地降低钒酸铋颗粒尺寸,提高钒酸铋颗粒的分散稳定性,实现对钒酸铋色调的调控.SDBS添加量为1.0 mmol时,制备的钒酸铋为单斜晶系白钨矿结构,颗粒无明显团聚,平均尺寸为115.21 nm,且分布集中,89％的颗粒尺寸在50～150nm.实现了钒酸铋由红色调黄到绿色调黄的转变,同时提高了钒酸铋的亮度L*.粉体色度参数 L*=89.10,a=-2.54,b*=71.82.
Abstract
In this paper,sodium dodecylbenzene sulfonate(SDBS)was used as structure directing agent to prepare bismuth vanadate pigment nanopowder by liquid phase method.The influence of SDBS on the morphology,phase,and chromaticity value of bismuth vanadate was investigated.The results show that SDBS can promote the growth of bismuth vanadate 121 crystal plane during the preparation of bis-muth vanadate.At the same time,it effectively reduces the particle size of bismuth vanadate,improves the dispersion stability of bismuth vanadate particles and achieves the regulation of the color tone of bis-muth vanadate.When the amount of SDBS added is 1.0,the prepared bismuth vanadate has a monoclin-ic scheelite structure.The particles show no obvious agglomeration,with an average size of 115.21 nm and a concentrated distribution,with 89％ of the particles ranging in the size from 50 to 150 nm.The transformation of bismuth vanadate from red to yellow to green was achieved,while the brightness L of bismuth vanadate was improved,with a chromaticity value of L*=89.10,a*=-2.54 and b*=71.82.
