苯乙烯-马来酸酐共聚物的部分酯化物在颜料分散中的应用

Application of Partial Esterified Esters of Styrene-Maleic Anhydride Copolymer in the Dispersion of Pigment

本文用苯乙烯-马来酸酐共聚物（SM）的部分酯化物（SME）对酞菁蓝颜料进行表面改性处理,发现（SME）钠盐的加入对酞菁蓝颜料临界润湿表面张力、表面自由能、粒径分布和(?)电位等表面性质有明显的影响,能有效的改善酞菁蓝颜料的润湿性、流动性和在水中的分散稳定性。

Partial esterfied esters of styrene-maleic anhydride(SME) were applied in the modification of phthalocyanine blue. It has been found that the sodium salt of SME has significant effects on the critical wetting surface tensions, the surface tensions, the distribution of partical size and (?)-potential of phthalocyanine blue. It has also effectively improved the wetting property, flowability and the dispersing extent and stability in water of phthalocyanine blue.
