| titleOfInvention | The manufacturing method of polyacrylic acid water-absorbent resin with low leachable object |
| abstract | The invention discloses a kind of manufacturing methods of the polyacrylic acid water-absorbent resin with low leachable object, include the following steps：(a) it obtains containing unsaturated acrylic monomer and cross-linking agent aqueous solution, (b) unsaturated acrylic monomer will be contained and cross-linking agent aqueous solution monomer polymerize, the step of obtaining aqueous gel shape cross-linked polymer, (c) the step of aqueous gel shape cross-linked polymer is granulated into the gel particle that number average bead diameter is 0.5~10 millimeter in the course of the polymerization process or after polymerization, (d) temperature is used to be thermally dried for 80~170 DEG C of heat mediums to the gel particle after crushing, water content is obtained as 0.1~10wt%, the polymer that 16 hours stirring extractables are 1~20wt%, 16 hours stirring extractables of the polymer that heat drying obtains under the conditions of described reduce by 0~80%, advantage：Under the conditions of dosage of crosslinking agent is not increased, by regulating and controlling drying process temperature, a kind of water-absorbing resins with low leachable object can be efficiently obtained. |
