【摘要】：为提升有机颜料在水中的分散浸润性,以有机颜料酞菁蓝干滤饼为代表性着色剂,通过超声均质过程依次将其分散到苯丙单体及其亚微液滴中,再通过细乳液聚合制得包裹颜料颗粒在苯丙乳胶粒中的颜料亚微胶囊,并研究胶囊成膜性能。结果表明:超声均质过程可有效解离干滤饼中的颜料聚集体,进而实现颜料颗粒在单体及其亚微液滴中初级粒子形式的均匀稳定分散;颜料含量显著影响单体分散液的黏度及其可细乳化性;软硬单体比是决定胶囊成膜性能的最关键因素;当单体分散液中颜料含量为12%,软硬单体丙烯酸丁酯与苯乙烯质量比为6∶4时,细乳化体系和聚合过程稳定,所制亚微胶囊在水中有较好的分散性和浸润性,结构清晰,成膜性好,可直接用于织物涂料印花与涂料染色。
[Abstract]:In order to improve the dispersion and wettability of organic pigments in water, organic pigment phthalocyanine blue dry filter cake was used as the representative colorant. The encapsulated pigment particles in styrene-acrylic latex particles were prepared by microemulsion polymerization, and the film forming properties of the capsules were studied. The results show that the ultrasonic homogenization process can effectively dissociate pigment aggregates from dry filter cake, and then realize the uniform and stable dispersion of pigment particles in the form of primary particles in monomers and submicron droplets. Pigment content significantly affected the viscosity of monomer dispersion and its fine emulsification, and the ratio of soft to hard monomer was the most important factor to determine the film forming performance of the capsule. When the pigment content in the monomer dispersion is 12 and the mass ratio of butyl acrylate to styrene is 6:4, the fine emulsification system and polymerization process are stable, the microcapsules have better dispersity and wettability in water, and the structure is clear. Good film-forming property, can be directly used in pigment printing and dyeing of fabrics.
