Super absorbent resin with high absorbent velocity and preparation method

Provided are a super absorbent resin with a high absorbent velocity and a preparation method. A polymer and monomer aqueous solution composed of, by weight, 2-10 wt% of PVA, 18-26 wt% of PAAS and 3-9 wt% of AMPS is heated and dissolved. Copolymer gel is synthesized through electron beam radiation crosslinking and grafting. The copolymer gel is then subjected to swelling and immersion cleaning by an immersion cleaning liquid, and then subjected to extraction freezing and freeze-drying to obtain a super absorbent resin. The pH value, normal saline absorbent amount and centrifugal preservation amount of the super absorbent resin have reached international level, and the super absorbent resin is remarkably superior to famous super absorbent resin products (P is less than 0.01) at home and abroad especially in the absorbent amount and the absorbent velocity of triple-distilled water and is in international advanced level. The super absorbent resin has advantages of simple technology, good biocompatibility and safe usage. The super absorbent resin can be widely used in a plurality of fields of medical and health supplies such as uracratia mattresses, infant diapers, woman sanitary napkins and the like, water retention and moisture preservation of agriculture and forestry and the like. The super absorbent resin has great application and development values.
