摘要
采用反相乳液法,以可溶性淀粉为原料,N,N'-亚甲基双丙烯酰胺(MBAA)为交联剂,过硫酸钾为引发剂,Span60为乳化剂制备交联淀粉微球,并对其进行了红外表征,表明淀粉微球进行了交联。扫描电镜观察显示微球比较圆整,表面粗糙,有凹陷,粘连较多,形状规则,表面致密。采用正交试验,以平均粒径为指标,对交联淀粉微球制备工艺进行了优化,确定了最佳制备工艺条件为:交联剂用量为0.8g,油水体积比为3∶1,乳化剂用量为0.4g。
With soluble starch as raw material,N,N＇-methylene-bis-acrylamide（MBAA）as crosslinking agent,potas- sium persulfate as initiator, Span60 as emulsifier, crosslinked starch microspheres were prepared by inverse emulsion meth- od,and characterization was carried by infrared spectrometer. The results showed that the microspheres was erosslinked. Scanning electron microscopy showed that microspheres was round,the surface was roughness, regular and dense, and had depression and more adhesions. Average particle size as evaluation index, the microspheres preparation process was opti- mized by orthogonal test,determined the best preparation conditions was：the amount of crosslinking agent 0. 8g, oil-water volume ratio 3 ： 1,emulsifieddosage 0. 4g.
