吸水吸油双功能树脂的制备与表征

Preparation and characterization of bifunctional resin with water and oil absorption

以可溶性淀粉和甲基丙烯酸丁酯(MBA)为单体,硝酸铈(主要作用离子为Ce4+)和偶氮二异丁腈(AIBN)为复合引发剂,N,N-亚甲基双丙烯酰胺(BIS)和二乙烯基苯(DVB)为复合交联剂,制备出吸水吸油双功能树脂.结果表明:当可溶性淀粉和MBA的质量配比为3:2,Ce4+与AIBN的质量配比为1:1,BIS和DVB的质量配比为1:1时,制备的双功能树脂的吸水吸油达到最大值,分别为6 g/g和5.5 g/g.红外光谱和热失重分析表征显示单体进行了很好的交联,聚合物的热稳定性良好.

Bifunctional resin with water and oil absorption was prepared by using soluble starch and butyl methacrylate（MBA） as monomers,cerium nitrate（Ce4＋） and azobisisobutyronitrile（AIBN） as combined initiators,N,N-methylene acrylamide（BIS） and divinylbenzene（DVB）as cross-linking agents.The results show that the optimum monomer ratio,initiators ratio and crosslinking ratio values were：m（soluble starch）：m（MBA）=3：2;m（Ce4＋）：m（AIBN）=1：1;m（BIS）：m（DVB）=1：1.At this point,the water and oil absorption rates of bifunctional resin reach their maximum of 6g/g and 5.5g/g.The monomers are well cross-linked and the thermal stability of the polymer is excellent by using infrared spectrograph and thermogravimetry to characterize the structure and thermal stability of the bifunctional resin.
