【摘要】：分散染料可以分子状态溶于溶剂中,将含有染料单体的溶液进行微乳化,乳液形成的胶束可以达到纳米级别,形成液状纳米分散染料微乳。采用半连续预乳化种子微乳液聚合法,制备三种微乳液状纳米分散染料。对制备的微乳液状纳米分散染料进行表征,并研究了微乳液状纳米分散染料微乳液粒径、Zeta电位、粘度、表面张力、粒子形貌、体系流变性及染色印花性能。结果表明,三种微乳液状纳米分散染料微乳液的胶粒粒径均在50~150 nm,固体胶粒粒径在50~70 nm,Zeta电位在-50 m V左右、表面张力在45 m N/m左右、粘度在2.5m Pa·s左右,体系接近牛顿流体。在SEM图中,微乳液粒子均为规则的球形,微乳液对涤纶有较高的上染率及印花转移率。
[Abstract]:Disperse dyes can be dissolved in solvent in molecular state, and the solution containing dye monomer can be microemulsified. The micelles formed by emulsion can reach nanometer level and form liquid nano-disperse dye microemulsion. Three kinds of microemulsion nano-disperse dyes were prepared by semi-continuous pre-emulsified seed microemulsion polymerization. The microemulsion nano-disperse dyes were characterized and the Zeta potential, viscosity, surface tension, particle morphology, rheological properties and dyeing printing properties of microemulsion nano-disperse dyes were studied. The results show that the particle size of the three microemulsions is 50 ~ 150 nm, the Zeta potential of solid particles is about -50 MV, the surface tension is about 45 mm / m, the viscosity is about 2.5 MPA / s, and the system is close to Newtonian fluid. In the SEM diagram, the microemulsion particles are regular spherical, and the microemulsion has higher dye uptake and printing transfer rate.
