摘要
采用自制的具有聚合物结构的端羟基聚醚型3-羟基-2-萘甲酸衍生物作为合成C.I.颜料红57∶1的第二偶合组分,采用共偶合工艺对C.I.颜料红57∶1进行了水性化改性。研究了衍生物在颜料合成中的最佳添加量,着重讨论了改性后的C.I.颜料红57∶1在水介质中的分散性能。结果表明:衍生物的最佳添加量为理论生成颜料质量的5%;与未改性的颜料相比,改性后颜料粒径缩小一半;离心分散100 min后所得水性色浆比吸光度为0.166,色浆黏度下降至102.7 mPa·s,即改性后的颜料分散稳定性得到了明显提高。
An in-house prepared hydroxyl-terminated polyether 3-hydroxy-2-naphthoic acid deriwltive was used as the second coupling composition of C.I. pigment red 57 ： 1, which was then modified fbr preparation of waterborne C.I. pigment red 57 ： 1 by co-coupling technol- ogy. The best dosage of derivative was studied, fbcusing on the dispersibility of modified C.I. pigment red 57 ： 1 in water. The results showed that the best dosage of derivation was 5% of the pigment theoretically, and the particle size of the waterborne C.I. pigment red 57：1 was only half of the unmodified pigment. The dispersibility of the modified pigment has been significantly improved.
