| 目的 研究中和度、交联剂用量、引发剂用量以及聚合单体丙烯酸钠含量等条件对其吸水吸湿性能的影响。初步探讨了同种材料的吸水和吸湿性能的关系。方法 以N，N′-2亚甲基双丙烯酰胺（MBAA）为交联剂，过硫酸钾为引发剂，采用水溶液聚合法合成了聚丙烯酸钠/凹凸棒石复合材料。结果由正交实验分别确定了吸水和吸湿用材料合成的最佳反应条件，其吸湿率最高达4.0g/ g、吸水倍率达到910倍。结论 凹凸棒石可以改良高吸水树脂的吸湿性能。 |

| Objective To study the effects of the neutralization degree, the amount of cross-linking agent and initiator agent, and the content of sodium acrylate monomer on the moisture-absorbing properties. Methods In this paper, the authors synthesized the dusty attapulgite mineral/ sodium polyacrylate superabsorbent composite material by the water solution polymerization using MBAA as the cross-linking agent and potassium persulfate as the initiator agent. ResultsThe optimal reaction conditions for the synthesis of moisture and water absorbent material were determined through the orthogonal experiments. The optimum moisture absorbency of the material reached4.0g/ g based on the orthogonal experiment results and the deionizing water absorption was910g/g.Conclusion Attapulgite mineral can change the properties of sodium polyacrylate superabsorbent. |
