摘要
淀粉接枝改性是将淀粉与某种特殊性能的单体聚合在一起,提高淀粉使用价值的一种方法。实验以丙烯酰胺为聚合单体,对豌豆淀粉进行改性,以过硫酸钾和亚硫酸钠组成的氧化还原体系为引发剂、尿素为抗交联剂、乙二胺四乙酸二钠为抗阻聚剂,以水溶液聚合法制备淀粉接枝丙烯酰胺聚合物絮凝剂,采用三元二次回归正交旋转组合实验,分析反应温度、引发剂浓度、原料配比对产物絮凝性能的影响。结果表明,反应温度为60℃、引发剂为5.00mL和原料配比为2.25时絮凝效果最好。
Starch graft modification, which was polymerization of starch and some pecial monomer, was a practicable way to improve the starch＇s value - inuse. Pea starch and aerylamide were used as the raw materials, potassium peroxodisuffate and sodium sulfite were used as the initiator, EDTA （ Ethylene Diamine Tetraaeetic Acid） and urea were used as the auxiliaries to make starch grafting aerylamide polymer flocculating agent by the method of aqueous solution polymerization. The influence of reaction temperature, concentration of initiator and raw material ratio on the flocculating performance products was analyzed by ternary quadratic orthogonal regression rotational combination experiment. The results showed that the flocculation effect would be the best when the reaction temperature was 60℃ , the initiator was 5.00mL, and the raw material ratio was 2.25.
