摘    要:2B酸重氮化与2,3酸偶合,30分钟后,填加阴离子表面活性剂,用氯化钙进行色淀化得标题颜料。分散剂MF、扩散剂NNO、聚丙烯酸、红油使颜料的鲜艳度、着色力和透明度提高,色光有所变化;MF、NNO和聚丙烯酸使颜料的流动性提高;红油、十二烷基磺酸钠使流动性下降;阴离子表面活性剂可提高颜料在二甲苯中的分散性。

关 键 词:C.I.颜料红48:2  表面改性  阴离子表面活性剂

Abstract:2B acid was diazotised and coupled with 2,3-acid, an anionic surfactant was added after 30 min., then laked with CaCl2 to give the title pigment. The brightness and color strength and transparency of the pigment were improved by adding dispersant MF, NNO, polyacrylic acid and Red Oil, and a slightly change in hue was observed; the flowability of the pigment was improved by adding dispersant MF, NNO and polyacrylic acid, but decreased by adding Red Oil and sodium dadecane sulfate; the dispersibility of the pigment in xylene was improved by adding anionic surfactant.
Keywords:C  I  Pigment Red 48:2  suface modification  anionic surfactant
