Preparation method of super absorbent polymer |
| abstract |
The present invention relates to a manufacturing method of a super absorbent polymer. The manufacturing method of a super absorbent polymer according to the present invention may include: carrying out a thermal polymerization or a photopolymerization of a monomer composition including a water-soluble ethylene-based unsaturated monomer and a polymerization initiator to form a hydrogel polymer; drying the hydrogel polymer; pulverizing the dried polymer; classifying the pulverized polymer into a fine powder having a particle diameter of less than 150 μm and a polymer having a particle diameter of 150 to 850 μm according to the particle diameter; performing reassembly by mixing and wetting the fine powder with 5 to 30° C. water in a content of 50 to 200 parts by weight with respect to 100 parts by weight of the fine powder having a particle size of 150 μm or less, to form a fine powder reassembly; and mixing the polymer having a particle diameter of 150 to 850 μm with the fine powder reassembly, followed by surface cross-linking, and may obtain a super absorbent polymer having a high fine aggregation strength. |
