| 摘 要： | 以改性麦秸秆、丙烯酸类单体为原料,与季铵盐改性的蒙脱土(OMMT)原位溶液聚合制备高吸水性树脂,其吸水能力、耐盐性均有较大提高。考察了改性麦秸秆用量、OMMT掺量、引发剂含量等对复合树脂吸(盐)水能力的影响,并用傅利叶变换红外光谱(FT-IR)、X射线衍射(XRD)、透射电镜(TEM)等方法表征了高吸水性树脂的结构及内部形貌。结果表明,聚合后蒙脱土片层剥离,在复合材料中达到纳米级分散;蒙脱土的含量越大,树脂的网孔越小,交联程度越大。

| Abstract: | A series of super absorbent resins were synthesized by in-situ polymerization with modified wheat straw,acrylic monomers and OMMT as raw materials.Its water absorption capacity and salt-tolerance were improved greatly.The influences of the amount of the modified wheat straw,OMMT and initiator on the water(salt) absorbency were studied.The structure and component of super absorbent resin were characterized by Fourier transform infrared ray(FT-IR),X-ray diffraction(XRD) and transmission electron microscope(TE... |
