摘要:
在高岭土存在下,以 N,N-亚甲基双丙烯酰胺作交联剂,以过硫酸钾作引发剂,部分中和的丙烯酸单体进行聚合交联反应,合成高聚物 /无机杂化高吸水性材料 .采用正交设计法,研究中和度、单体用量、引发剂量、交联剂量、高岭土加入量及反应温度对吸水率的影响 .结果表明,高岭土的复合,可显著提高材料的吸水率,达 980 m L· g-1.对生理盐水溶液的吸水率达 95m L· g-1.
Abstract:
A hybridized material consisting of polyacrylic acid and kaolin is found to have high water absorbent performance.This polymer/inorganically hybridized material is synthesized by polymerization and cross linking reaction.The partially neutralised acrylic acid as the monomers are polymerized and cross linked to kaolin,with potassium persulfate as initiator and N.N methylene bis acrylamide as cross linking agent.Regarding water absorption of this material,a study is made on such influencing factors as degree of neutralization,consumption of monomer,amount of initiator and cross linking agent,amount of kaolin addition,and reaction temperature.As indicated by experimental results,water absorption can be greatly increased.The water absorption of this material will approach 980 mL·g -1,while its water absorption from normal saline will approach 95 mL·g -1 .
