titleOfInvention | The manufacturing method of polyacrylic acid water-absorbent resin with low leachable object |
abstract | The invention discloses a kind of polyacrylic acid water-absorbent resins with low leachable object and its manufacturing method, manufacturing method to include the following steps:It obtains containing unsaturated acrylic monomer and cross-linking agent aqueous solution; unsaturated acrylic monomer will be contained and cross-linking agent aqueous solution monomer polymerize; obtain aqueous gel shape cross-linked polymer; aqueous gel shape cross-linked polymer is granulated into water content as 30~80wt% in the course of the polymerization process or after polymerization; number average bead diameter is 0.5~20 millimeter; and the gel particle that the mass fraction more than 2 millimeters is 30~100wt%, the gel particle after granulation is dried, grain refined and is sieved.Advantage:Under the conditions of dosage of crosslinking agent is not increased, by regulating and controlling gel particle size in drying process, a kind of water-absorbing resins with low leachable object can be efficiently obtained. |
