The Effect of Clay Kind on Properties of Corresponding Poly（Acrylic Acid/Acrylamide/Clay） Superabsorbents
英文摘要
A series of poly（acrylic acid/acrylamide/clay） superabsorbents with 10% different kinds clay,which including calcined kaolin,montmorillonite,attapulgite,bentonite,sepiolite and diatomite,were prepared by inverse suspension polymerization method.The effects of clay kinds on structure,equilibrium water absorbency,equilibrium 0.9% NaCl absorbency,the water-retention capability and thermal stability of the superabsorbent composites were also systematically investigated in the same condition.It is found that the superabsorbent incorporated with bentonite has the best equilibrium water absorbency（450 g/g） and equilibrium 0.9% NaCl absorbency（92 g/g）.Moreover,bentonite and calcined kaolin ones show the best capability of maintenancewater.Besides,the calcined kaolin can enhance the thermal stability of corresponding superabsorbent to the highest degree.
