摘　　要：利用鱼蛋白与丙烯酸通过水溶液聚合法接枝共聚制备鱼蛋白高吸水剂,以N,N-亚甲基双丙烯酰胺为交联剂,过硫酸钾为引发剂,对配方进行优化,合成了鱼蛋白相对丙烯酸质量分数分别为10%、20%、30%的吸水剂,通过对产品的测试,比较了不同鱼蛋白用量下的吸水剂性能.结果表明,3种最佳产物在人工尿液中的吸液倍率分别达77.59 g/g、73.64 g/g和65.43 g/g,质量分数为10%的鱼蛋白吸水剂吸(盐)水性能、吸人工尿液倍率、不同pH下的溶胀能力和耐热、耐光、耐寒性能都优于质量分数为20%或30%的,而保水能力均相当.The superabsorbent was synthesized with acrylic aid and its natrium salt grated on fish protein. Three different superabsorbents were synthesized in the suitable condition with N, N- methylene-bis-aerylamide as crosslinker, potassium persulfate as initiator, and fraetio of 10%, 20%, 30% of fish protein content respectively. Through testing, the properties of superabsorbent were compared. The experimental results show that three products＇ absorbency for manpower liquid was 77.59 g/g,73.64 g/g and 65.43 g/g respectively. The 10% product has good capability in the distilled water,salt water and swelling in different pH to the 20% ＇ s or 30% ＇ s, and also excels in its capability of enduring heat,ray and cold. But the capability of restraining water all equal .
