摘要: 以可生物解聚丁二酸丁二酯(PBS)为基材,用乳液蒸发法制备不同负量荧光颜料/PBS 胶。用粒度仪扫电电表征胶粒径和形貌用测色计和荧光光谱仪测定胶色度及荧光性能。结果表明,在颜料与PBS质量比例为1:1、2:1、3:1时,所得胶M1、M2、M3平均粒径分别为12.3μm、10.5μm、12.5μm 粒外形规,分性好。相比于纯颜料,颜料胶M1、M2、M3在塑料中分后,度(AC)均增加,荧光性能得到保持。

Abstract: Poly(butylene succinate)(PBS)microcapsules were prepared via emulsion solvent evapora- tion process, with different amount of pigment loading. The dian meters and morphology of microcapsules were characterized uisng SEM, TEM and particle size distributio in analyzer. Colorimeter and fluorescent photometer were used to measure the chroma and fluorescence. It was found that microcapsules showed regular morphology and dispersibility, when the ratios of pigmen t to PBS were 1:1, 2:1 and 3 :1( due to product M,M2,M3). The mean diameter of M1, M2, M3 was 12.3 μm, 10.5 μm and 12.5 μm, respectively. The pigment in microcapsules( M1, M2, and M3) was more vivider than pure powder of pigment, and their fluorescence was still maintained.

Key words: poly(butylene succinate);microcapsule, fluorescent pigment, dispersibility, chroma
