Antibacterial and deodorant super absorbent resin and preparation method thereof

The preparation method comprises the following steps: (1) uniformly mixing deionized water and acrylic acid, adding a sodium hydroxide aqueous solution for neutralization, controlling the neutralization degree of the acrylic acid to be 50%-90%, then adding a functional monomer and a cross-linking agent into the acrylic acid neutralization solution, uniformly stirring, then adding an initiator, heating to 30-50 DEG C, and reacting for 1-2 hours; cutting, drying, crushing and screening the water-absorbent resin colloid to obtain water-absorbent resin particles; and (2) condensing the aminated cellulose nanocrystals and water-absorbent resin particles to obtain modified water-absorbent resin, then loading the antibacterial component and the deodorizing component into the modified water-absorbent resin under the physical action of the aminated cellulose nanocrystals and the antibacterial component and the deodorizing component, and drying at 100-120 DEG C to obtain the antibacterial and deodorizing super absorben
