| 摘 要： | 采用聚合物包覆颜料可以阻止颜料粒子之间的聚集,提高颜料的耐候性,增强使用性能.通过细乳液聚合法实现聚苯乙烯和聚丙烯酸酯对偶氮结构有机颜料的表面包覆.研究了颜料P.Y.65、P.Y.73、P.Y.14、P.Y.83在水中和单体中超声乳化后的分散性能.随着超声时间的延长,颜料在水中的分散粒径减小;超声30 min时,颜料P.Y.14、83的分散粒径比颜料P.Y.65、P.Y.73的小.颜料在苯乙烯中的分散粒径较小.颜料P.Y.83分散于单体中形成的分散液稳定性较好,而颜料P.Y.65/单体分散液的稳定性最差.聚合物对颜料P.Y.83的包覆率和包覆效率均高于颜料P.Y.65,聚丙烯酸酯(PMA、PBA)对颜料的包覆率高于聚甲基丙烯酸酯(PMMA、PBMA).

| Abstract: | Encapsulation of pigments with polymers can protect them from agglomeration,improve weathering resistance of pigments and increase the application properties.The organic pigments with azo structure were encapsulated with polystyrene and polyacrylates via miniemulsion polymerization.The dispensability of organic pigments(P.Y.65,P.Y.73,P.Y.14 and P.Y.83) in water and monomers after ultrasonic emulsification were evaluated.With ultrasonication time prolonging,the particle size of pigment dispersions decreased.... |
