XG-g-P(AA-co-AM)/AC复合高吸水性树脂的制备与性能
Preparation and characterization of XG-g-P(AA-co-AM)/AC composite super absorbent resin
摘要
Abstract
The composite super absorbent resin, xanthan gum-g-poly (acrylic acid-co-cryl amide) / attapulgite clay with good salt tolerance was synthesized through inverse suspension copolymerization. The influence factors of preparing composite super absorbent resin were studied. FT-IR, XRD and TGA were used on characterization of the super absorbent resin. The results showed that: Si-OH and AM/AA participated in graft polymerization reaction with xanthan gum. The preparation of super absorbent resin under optimum conditions has good properties of water absorption and salt resistance, with the highest water absorption up to 871.2 g/g and 0.9% NaCl solution absorption up to 119.8 g/g. Degradation tests showed that super absorbent resin could be degraded by microbes, and the degradation degree was up to 26.1% within 90 days.关键词
