【摘要】 介绍了由腈纶丝常压皂化水解,Al³⁺交联制备高吸水树脂的新工艺。研究了水解工艺条件对水解产物的影响及水解产物粘度、交联剂用量、吸收的水质等对吸水率的影响。制得的高吸水树脂吸收蒸馏水可达477g/g,吸收生理盐水可达55g/g。更多还原

【Abstract】 Super absorbent resin was prepared by the process of alkaline hydrolyzation of PAN waste fibers,and then by cross-linking with Al³⁺.The influence of the technological conditions on hydrolyzation product,and the influence of the viscosity of hydrolyzed PAN,the amount of cross-linking agent,the quality of water on the absorbing ratio were stud- ied.The obtained super absorbent resin can absorbe distilled water 477 g/g,physiological saline 55 g/g.更多还原
