摘要随着办公自动化与信息化的发展，对快速输出高清晰的彩色图像和文字提出了更高的要求，传统熔融粉碎法制备的墨粉粒径较大，粒形不规则，导致打印质量下降。因此，通过化学聚合法制备彩色墨粉已成为研究的主要方向。本文利用细乳液聚合制备彩色墨粉用乳胶粒子，并通过凝聚技术和微胶囊技术，最终制备符合打印机实际需要的粒径及粒径分布的彩色墨粉。

通过纳米乳胶粒子凝聚复合制备微米复合粒子的实验研究，研究纳米乳胶粒子凝聚复合、粒径控制及固结成型的原理及工艺方法，掌握乳液聚合法彩色墨粉复合粒子的制备方法，实现各功能组分粒子的复合包覆及粒径的稳定控制；了解彩色墨粉复合粒子粒径、形貌、性能表征方法。实验发现：当絮凝剂用氯化铝，体系浓度20mmol/L，搅拌速度为200r/min，熟化时间30min，温度为95度时凝聚效果比较好。64133

Title   The cohesion of color toner used nano latex particles  prepared by mini-emulsion polymerization

Abstract With the development of office automation and information technology, fast output high-definition color images and text put forward higher requirements, traditional melt crushed prepared toner particle size, grain shape is irregular, resulting in deterioration in print quality. By chemical polymerization method color toner has become the main direction of the study In this paper, the fine emulsion polymerization color toner latex particle, and by cohesion technology and microencapsulation technology, the final preparation of the actual needs of the particle size of the composite printer, the color toner particle size distribution.

Experimental study through the latex nanoparticles cohesion composite prepared micron composite particles, the nano-latex particles to agglomerate composite, particle size control and consolidation molding principle and process of the master color toner of the composite particles of the emulsion polymerization method, preparation method thereof, realizing the functions component composite coated particles and particle size stability control; understand the composite color toner particle size, morphology, Characterization method.

It was found that: When using aluminum chloride as flocculants, system concentration 20mmol / L, stirring speed 200r/min, aging time 30min, aging temperature 95 degrees ,the cohesion results were better.
