Using aqueous solution polymerization method,using sodium alginate(SA),kaolin,acrylic acid (AA) and 2-acrylamide-2-methylpropanesulfonic acid (AMPS) as monomers to synthesize SA-P(AA/AMPS)-kaolin salt tolerant super absorbent resin (SRSAR).The microstructure and thermal stability of SRSAR were analyzed by FT-IR,SEM,TGA and other test methods,and tested water retention,salt resistance,repeated water absorption and smart expansion.The results shown that the water absorption rate and salt water absorption rate of the synthesized SRSAR under the optimal conditions were 641.5g·g-1 and 83.2g·g-1,respectively.Compared with the traditional super absorbent resin,the salt resistance and thermal stability were obvious Improved.It can keep water for a long time at room temperature,and after repeated water absorption for 5 times,the water absorption capacity only losed 2.7%,and the salt water absorption capacity losed 11.5%.It had good repeated use performance and intelligent expansion performance.
