摘要：采用 1，4-二氨基蒽醌作为发色体，与异佛尔酮二异氰酸酯反应生成紫色预聚物，与聚乙二醇 600 通过界
面聚合法制备了氨基蒽醌紫色聚氨酯微球。考察了乳化剂种类、用量、乳化速度、发色体用量对微球粒径的影
响。结果表明，与聚氧乙烯辛基苯酚醚-10、失水山梨醇单油酸酯聚氧乙烯醚（Tween80）和失水山梨糖醇单油
酸酯（Span80）相比，十二烷基苯磺酸钠（SDBS）乳化剂更适合用于聚氨酯球的制备。SDBS 质量分数 3.5%
（以油相为基准）的粒径分布最窄，微球粒径在 350 nm 左右。微球平均粒径随乳化速度增大而减小，在 8000 r/min
时粒径分布最集中。发色体在壳层体系中加入量为 1 mmol 时粒径分布系数最小，平均粒径 500 nm。通过 SEM
和 TEM 表征，结果显示，聚氨酯微球粒径在 500 nm 左右，呈表面光滑的球形，内部呈空心结构。氨基蒽醌聚
氨酯紫色微球印花织物颜色性能优异，且具有较高色牢度。

Abstract: 1,4-Diaminoanthraquinone (DA) as chromogen was reacted with isophorone diisocyanate (IPDI)
to form a purple prepolymer, followed by interfacially polymerized with polyethylene glycol 600 to prepare
amino-anthraquinone polyurethane microspheres (DAPM). The effects of emulsifier type, emulsifier dosage,
emulsifying speed and chromogen dosage on the particle size of microspheres were investigated. The
results showed that sodium dodecylbenzenesulphonate (SDBS) emulsifier was more suitable for the
preparation of polyurethane microspheres than octaphenyl polyoxyethyiene-10 (OP-10), polyoxyethylene
sorbitan monooleate (Tween80) and sorbitan monooleate (Span80). When SDBS mass fraction was 3.5%
(based on the oil phase), the particle sizes of the microspheres were all around 350 nm with the narrowest
particle size distribution. The average particle size decreased with the increase of emulsifying speed, when
the emulsifying speed was 8000 r/min, the particle size distribution was the most concentrated. When the
chromogen dosage was 1 mmol, the prepared microspheres exhibited the narrowest distribution with a
particle size of 500 nm. SEM and TEM observations revealed that the as-prepared amino-anthraquinone
polyurethane microspheres had a particle size of about 500 nm with smooth spherical surface and hollow
internal structure. The fabric printed with DAPM had excellent color properties and color fastness.
