Abstract
The invention discloses a preparation method of a poly-(acrylic acid-acrylamide)/ hydrotalcite super water absorbent resin, wherein, the method utilizes hydrotalcite with organic modification as an inorganic filler, cyclohexane as a solvent, the crylic acid and the acrylamide as monomers; by adopting the principle of in-situ polymerization, the hydrotalcite is peeled off from a polymer matrix to prepare a nano composite super water absorbent salt-resistant resin. The super water absorbent salt-resistant resin obtained by the preparation method has the maximum water absorption rate of 1100g/g, the maximum salt-resistant rate of 145g/g, the artificial-blood absorption rate reaching 72.8g/g and the artificial-urine absorption rate reaching 80.7g/g.
