摘要
以玉米淀粉为原料,与丙烯酸发生接枝共聚反应,以过硫酸钾为引发剂,N,N-亚甲基双丙烯酰胺为交联剂,制得玉米淀粉/聚丙烯酸钠高保水复合材料;通过干燥粉碎,进行性能测定,研究引发剂添加量、玉米淀粉添加量、丙烯酸和NaOH的中和度和交联剂添加量等因素对吸水倍率和耐盐倍率的影响。结果表明:在丙烯酸单体为50.00 g时,玉米淀粉添加量为10.00 g,引发剂添加量为0.15 g,交联剂添加量为0.02 g,中和度为90%时,生成的高保水材料性能最好,吸水倍率可达到240倍左右,耐盐倍率达到40倍左右。
A novel kind of superabsorbent composite was synthesized used corn starch as monomer,K2SO4 as initiator,and N,N-methylene-bis-acrylamide as crosslinking agent by means of graftcopolymerization with acrylic.After drying,grinding,this material of the performance of water and salt resistance was measured.Base on the result,the influence of initiator,corn asylum,acrylic,NaOH in degree and cross linking agent additive on quantity of water preserving rate and salt resistance rate were studied.The result showed that when the acrylic monomers was 50.00 g and corn asylum was 10.00 g,initiator additives was 0.15 g,cross linking agent additives was 0.02 g,neutralization degree was 90%,the performance of the material was best.Bibulous rate was increased by 240 times,salt tolerance rate was increased by 40 times.
