▎ 摘　　要

NOVELTY - A superabsorbent resin comprises polyacrylate superabsorbent resin having predetermined degree of crosslinking as matrix resin. Tea saponin intercalated graphene antimicrobial composition is bonded between network molecular chains in superabsorbent polymer. The superabsorbent resin composition comprises 100 pts. wt. acrylic acid, 35-45 pts. wt. basic compound, 0.06-1.8 pts. wt. primary crosslinking agent, 0.05-2 pts. wt. initiator, 0.3-4 pts. wt. composite crosslinking agent and 0.01-10 pts. wt. tea saponin intercalated graphene antimicrobial composition. USE - Superabsorbent resin is used for medical supplies and disposable hygienic product (all claimed). ADVANTAGE - The superabsorbent resin has excellent antibacterial characteristics and salt resistance. DETAILED DESCRIPTION - A superabsorbent resin comprises polyacrylate superabsorbent resin having predetermined degree of crosslinking as matrix resin. Tea saponin intercalated graphene antimicrobial composition is bonded between network molecular chains in superabsorbent polymer and/or three-dimensional crosslinked network structure on surface of superabsorbent polymer. The superabsorbent resin composition comprises 100 pts. wt. acrylic acid, 35-45 pts. wt. basic compound, 0.06-1.8 pts. wt. primary crosslinking agent, 0.05-2 pts. wt. initiator, 0.3-4 pts. wt. composite crosslinking agent and 0.01-10 pts. wt. tea saponin intercalated graphene antimicrobial composition. An INDEPENDENT CLAIM is included for preparation of superabsorbent resin, which involves diluting mixture of acrylic acid/acrylic acid salt with deionized water and neutralizing with acrylic monomer solution from basic compound, adding primary crosslinking agent and evenly stirring mixture, adding 0-45% tea saponin intercalated graphene antibacterial composition, ultrasonically dispersing mixture for 30-240 minutes, heating mixture at 35-70 degrees C, adding polymerization initiator, granulating and drying mixture and surface treating dried product with composite crosslinking agent at 110-180 degrees C.
