摘要
以改性羽毛蛋白(MFP)、丙烯酸(AA)和丙烯酰胺(AM)为主要原料,N,N′-亚甲基双丙烯酰胺为交联剂,硫酸钾-亚硫酸氢钠为引发剂,采用溶液聚合法制备了羽毛蛋白接枝聚丙烯酸-丙烯酰胺高吸水树脂[P(MFP-g-AA/AM)],并对其吸水性能及其影响因素进行了考察。结果表明,P(MFP-g-AA/AM)制备的最适宜工艺条件为WAA∶WAM=70∶30,丙烯酸的中和度为90%,WMFP∶WAA+AM=10%,Winitiator∶WAA+AM=0.8%,Wcrosslinker∶WAA+AM=0.10%,反应温度为60℃,反应时间为2h。在此条件下合成的P(MFP-g-AA/AM)树脂在去离子水中的饱和吸水倍率为578.0g.g-1,吸盐水(0.9%NaCl)倍率为78.6g.g-1,吸人工尿液倍率为75.1g.g-1,均高于羽毛蛋白接枝丙烯酸树脂。
Modified feather protein grafted poly（acrylic acid-acrylamide）superabsorbents [P（MFP-g-AA/AM）] were synthesized by using modified feather protein（MFP）,acrylic acid（AA）and acrylamide（AM）as start materials,N,N＇-methylenebisacrylamide（NMBA）as crosslinker and K2S2O8-NaHSO3 as initiator.The water absorbency performance and its influence factors of the P（MFP-g-AA/AM）superabsorbents were investigated.The results showed that the preferable synthesis conditions for P（MFP-g-AA/AM）were as follows：WAA∶WAM=70∶30,WMFP∶WAA＋AM=10%,Wcrosslinker∶WAA＋AM=0.10%,Winitiator∶WAA＋AM=0.8%,neutralization degree of the acrylic acid 90%,reaction temperature 60℃ and reaction time 2 h.The absorbency of the P（MFP-g-AA/AM）superabsorbents was 578.0 g·g^-1 in the case of de-ionized water,78.6 g·g^-1 in the case of 0.9% NaCl solution and 75.1 g·g^-1 in the case of artificial urine,higher than the absorbency of modified feather protein grafted acrylic acid superabsorbents.
