Abstract
Disclosed are a superabsorbent polymer having improved anti-caking properties and a method of preparing the same, and the superabsorbent polymer having improved anti-caking properties includes a superabsorbent polymer, microparticles, and water, and to improve anti-caking properties of the superabsorbent polymer, the temperature of the superabsorbent polymer or water upon addition of water or the aging time upon stirring is adjusted, thereby preventing caking of the particles.
Claims24
A method of preparing a superabsorbent polymer having improved anti-caking properties, comprising:
- performing heating treatment on at least one of a superabsorbent polymer, particles, or water to form heated components, wherein the superabsorbent polymer, the particles, and the water are components;
- and
- mixing the heated components together, or mixing the heated components with the remaining unheated components, to prepare a superabsorbent polymer having improved anti-caking properties,
- wherein the particles are present in an amount of 0.0001 15.0 parts by weight, based on 100 parts by weight of the superabsorbent polymer, and wherein the particles have a BET specific surface area of 300 1500 m2/g and a porosity of 50% or more, and
- wherein the water is present in an amount of 0.1 20.0 parts by weight based on 100 parts by weight of the superabsorbent polymer and the particles.
