摘要
采用细乳液聚合法制备了纳米乳胶荧光颜料,研究了溶剂黄43用量,乳化剂、助乳化剂种类和用量,引发剂用量和超声波处理时间对纳米乳胶荧光颜料性能的影响。结果表明,纳米乳胶荧光颜料较佳的制备工艺为:溶剂黄43、十六烷(HD)和过硫酸铵(APS)的质量分数分别为1.5%、1.5%和0.8%(以单体质量计),乳化剂1-烯丙氧基-3-(4-壬基苯酚)-2-丙醇聚氧乙烯(10)醚硫酸铵(DNS-86)用量为0.019 11 mol/L,超声波处理时间9 min,在该条件下制备的纳米乳胶荧光颜料的粒径为162.1 nm,具有较高的耐热和离心稳定性,纳米乳胶荧光颜料的最大荧光发射波长517 nm,最大吸收波长425 nm。
The nanoscale latex fluorescent pigment was prepared by miniemulsion polymerization method. The effects of solvent yellow 43 dosage,kinds and amount of emulsifier and co-emulsifier,amount of initiator and ultrasound treatment time on its performance were investigated. The results indicate that the optimized synthesis conditions were that the mass fraction of solvent yellow 43,hexadecane and initiator based on the weight of monomers was 1. 5%,1. 5% and 0. 8%,respectively,the concentration of DNS-86 was 0. 019 11 mol / L,and the ultrasound treatment time was 9 min. The nanoscale latex fluorescent pigment prepared under the optimal conditions showed excellent stability with a particle size of 162. 1 nm. The maximum fluorescence emission wavelength of the nanoscale latex fluorescent pigment was 517 nm,and the maximum absorption wavelength was 425 nm.
