Preparation and Characterization of LPAAM Superabsorbent Composite

Abstract:

Article Preview

Kaolin/sodium lignosulfonate graft acrylic acid and acrylamide superabsorbents composites(LPAAM) were prepared by solution polymerization using sodium lignosulfonate, acrylic acid and acrylamide as raw materials, kaolin as inorganic filler, potassium peroxydisulfate as initiator, N,N’-methylene-bis-acrylamide as crosslinker and by saponifying 2h under 90 , 0.10mol/L NaOH solution. Its equilibrium absorbencies in distilled water and 0.9%NaCl solution are 1003g/g and 89g/g, respectively. The structure, morphology and thermal property are testing by FTIR, SEM and TG, respectively.
