Abstract: Using acrylic acid and soluble starch as the main raw materials, ammonium persulfate as the initiator, N-N′-methylenebisacrylamide as the crosslinking agent, and acrylamide as the monomer,the super absorbent resin (SAR) is synthesized by aqueous solution polymerization. The L25(55) orthogonal test was designed to determine the SAR preparation conditions, and appropriate amounts of kaolin, montmorillonite, and laponite were respectively added to prepare composite super absorbent resin. Use FT-IR, SEM-EDS, TG, etc. to characterize the composite super absorbent resin. The liquid absorption and water retention of the composite super absorbent resin were investigated. The SAR experiment conditions were following: the mass ratio of acrylamide starch was 5∶4, the synthesis temperature was 45 ℃, the initiator was 0.13 g, the crosslinking agent was 0.01 g, and the sodium hydroxide was 9 g. The results showed that under this condition, the maximum water absorption rate of SAR was 179.5 g/g, and the salt absorption rate was 70.75 g/g. FT-IR and SEM-EDS results show that the resin has been successfully prepared. The addition of inorganic kaolin, montmorillonite, and laponite improves the liquid absorption performance and thermal stability of SAR. The water absorption rate and salt absorption rate of SAR containing kaolin both reach the maximum, while the water absorption rate is 245.0 g/g and salt absorption rate is 83.3 g/g.
