摘　　要：为了提高C.I.颜料橙68的应用性能,以萘酚聚氧乙烯醚、烷基二苯醚双磺酸钠以及两者的复配溶液为表面活性剂,对C.I.颜料橙68粗品进行了表面改性。对改性前后颜料的颜色、粒径和表面极性以及在水中的分散稳定性进行了测试。结果表明:表面活性剂的添加对颜料粒径及其分布起到较好的调控作用,用5%萘酚聚氧乙烯醚(EO=20)改性的颜料颗粒粒径最小,粒径分布较为集中。且萘酚聚氧乙烯醚和烷基二苯醚双磺酸钠复配改性能显著增强改性颜料的表面极性。此外,表面活性剂改性后C.I.颜料橙68的鲜艳度提高(△c最高为0.84),着色力达114.9%,接触角由79°减小至61°,亲水性显著增加,在水中的分散稳定性明显提高。In order to improve the application performance of C.I.Pigment Orange 68.Naphthol polyoxyethylene ether,alkyl diphenyl ether disulfonates and their mixtures were employed as the surfactant to modify C.I.Pigment Orange 68 crude.The color performance,particle sizes and distribution,together with surface polarity of modified pigments were measured,In addition,the dispersion stability of modified pigment in water was evaluated.The results showed that the incorporation of surfactant mixture presented a regulatory effect on the particle sizes and distribution of pigment.The pigment modified by 5%naphthol polyoxyethylene ether(EO=20)displayed the smallest particle diameter and the more concentrated particle size distribution.The combined action of naphthol polyoxyethylene ether and alkyl diphenyl ether disulfonates significantly intensified the surface polarity of modified pigment.In addition,the color performance of C.I.Pigment Orange 68 had been obviously improved through incorporating the surfactant.The brightness of the modified pigment was increased(Δc=0.84),the maximum color strength reached 114.9%,the contact angle was reduced from 79°to 61°,and the hydrophilicity was significantly enhanced.The dispersion stability of modified pigment in water was significantly increased.
