▎ 摘　　要

NOVELTY - Super-absorbent salt-resistant potassium ion-based polymer water-absorbent resin comprises 25-75% anionic monomer, 1-45% cationic monomer, 0.005-5% crosslinking agent, 0-50% neutralizing agent, 0.01-5% initiator and 0.005-5% catalyst. USE - The super-absorbent salt-resistant potassium ion-based polymer water-absorbent resin is useful in the fields of sewage treatment, agriculture, medical and health, flexible sensors or construction (claimed). ADVANTAGE - The super-absorbent salt-resistant potassium ion-based polymer water-absorbent resin uses rice particles as cross-linking agent, introduces cationic monomers as counter ions, adjusts the degree of neutralization of anionic monomers and the ion type of water-absorbent resin by neutralizing agent, and improves the water absorption and salt resistance of water absorbent resin. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of the super-absorbent salt-resistant potassium ion-based polymer water-absorbent resin, comprising neutralizing the anionic monomer with a neutralizing agent, adding crosslinking agent, introducing initiator and catalyst and carrying out free radical copolymerization.
