| 摘 要： | 以糯小麦淀粉为原料,丙烯酸、丙烯酰胺、丙烯酸甲酯为单体,过硫酸铵为引发剂,N,N’-亚甲基双丙烯酰胺为交联剂,采用接枝共聚法制备耐盐性高吸水性树脂.研究了在氮气保护的情况下,丙烯酸中和度、丙烯酰胺用量、丙烯酸甲酯用量、反应温度,引发剂用量和交联剂用量对高吸水性树脂吸盐水性能的影响.得到的较优工艺条件为:丙烯酸中和度/pH5.8,丙烯酰胺14g,丙烯酸甲酯1mL,反应温度75℃,引发剂4％过硫酸铵溶液5mL,交联剂2％N,N’-亚甲基双丙烯酰胺溶液0.5mL.此条件下制备的高吸水性树脂吸盐水倍率达到62.1g·g-1. |
| 关 键 词： | 耐盐性 糯小麦淀粉 高吸水性树脂 吸水率 |

| Abstract: | A salt-resistance superabsorbent resin was prepared from graft copolymer by using the waxy wheat starch as the material,acrylic acid,acrylic amide and methyl acrylate as the monomer,ammonium persulfate as the initiator,N,N’-methylene-bisacrylamide as cross-linking agent.In the protection of nitrogen,the influence of neutralization degree of acrylic acid,the usage of acrylic amide and methyl acrylate,reaction temperature,amount of initiator,amount of cross-linking agent on salt water absorbing performance was studied.The superior preparatory processing conditions of waxy wheat starch superabsorbent resin with salt-resistance obtained were neutralization degree of acrylic acid/pH 5.8,acrylic amide 14 g,methyl acrylate 1 mL,reaction temperature 75 ℃,initiator 4% ammonium persulfate solution 5 mL,cross-linking agent 2% N,N’-methylene-bisacrylamide solution 0.5 mL.The salt water absorbency of prepared superabsorbent resin reached 62.1 g·g-1. |
| Keywords: | salt-resistance waxy wheat starch superabsorbent resin water absorbency |
