Abstract: The super water absorbing composites of calcined kaolin-sodium polyacrylate based on was prepared by solution polymerization using calcined kaolin and polyacrylate as raw materials. A study was made to discuss the influence of the amount of acrylamide, initiation, cross-linker, the extent of neutralization and the addition of calcined kaolin on the water absorbing property. The results show that when the content of acrylamide is 15%, the content of initiation and cross-linker is 0.25% and 0.08% respectively, the extent of neutralization is 80%, the content of calcined kaolin is 50%, the water absorption performance of the composites is the best that the distilled water absorbency is 890 g/g, the physiological saline absorbency is 70 g/g. The calcined kaolin is even dispersed in the composites.
