초록 ▼

A water absorbing agent of the present invention has an internal crosslinking structure obtained by polymerization of a water-soluble unsaturated monomer. The agent satisfies conditions (a) to (d): (a) the agent contains water-insoluble inorganic particles at an amount of from 10 ppm to 1,900 ppm inclusive; (b) the agent contains 5 mass % or less particles which have such a size that they can pass through a sieve having a mesh opening size of 150 μm; (c) the agent has an absorbency against a pressure of 4.83 kPa (AAP) of 18 g/g or more; and (d) the water-insoluble inorganic particles reside on a surface of the water absorbing resin or near the surface.

대표청구항 ▼

1. A water absorbing agent containing water absorbing resin particles, the agent satisfying conditions (A) to (H) below: (A) the water absorbing resin particles are, on a surface thereof, either crosslinked or coated with a surface crosslinking agent which has at least one hydroxyl group;(B) the water absorbing resin particles contain, on a surface thereof, a trivalent water-soluble metal salt and water-insoluble inorganic particles that include silicon dioxide;(C) the water absorbing agent has a mass median particle size of 200 μm to 500 μm inclusive;(D) the water absorbing agent contains 0.001 to 0.4 mass % inclusive, of the water-insoluble inorganic particles;(E) the water absorbing resin particles have a size such that no more than 5 mass percent of such particles can pass through a sieve having a mesh opening size of 150 μm;(F) the water absorbing resin particles contain acid groups that are neutralized in a ratio from 50 mol% to 90 mol% inclusive; and(G) the water absorbing resin particles contain 0.001 to 5.0 mass % inclusive, of the trivalent water-soluble metal salt;(H) the water absorbing agent contains dust in an amount that is 355 ppm or less and that contains SiO2 in an amount which is 50 mass % or less. 2. The water absorbing agent of claim 1, wherein the water absorbing agent has a centrifuge retention capacity of 30 g/g inclusive to 50 g/g exclusive, and a saline flow conductivity (SFC) of 10 (10−7·cm3·s·g−1) or more. 3. A water absorbent core, comprising the water absorbing agent of claim 1. 4. A method of manufacturing a water absorbing agent containing water absorbing resin particles having a mass median particle size of 200 μm to 500 μm inclusive, comprising: (1) polymerizing a water soluble unsaturated monomer to obtain water absorbing resin particles;(2) either crosslinking or coating the water absorbing resin particles on a surface thereof with a surface crosslinking agent which has at least one hydroxyl group;(3) mechanically damaging the water absorbing resin particles, so as to irregularly pulverize such particles; and(4) mixing a trivalent water-soluble metal salt with the water absorbing resin particles;(5) further mechanically damaging the water absorbing resin particles mixed with the trivalent water-soluble metal salt; and(6) mixing the water absorbing resin particles with water-insoluble inorganic particles that include silicon dioxide, wherein the water absorbing agent contains dust in an amount that is 355 ppm or less and that such dust-contains SiO2 in an amount which is 50 mass % or less. 5. The method of claim 4, wherein the water absorbing agent has a centrifuge retention capacity of 30 g/g inclusive to 50 g/g exclusive, and a saline flow conductivity (SFC) of 10 (10−7·cm3·s·g−1) or more. 6. The method of claim 4, wherein the mixing the trivalent water-soluble metal salt comprises mixing the trivalent water-soluble metal salt as an aqueous solution with the water absorbing resin particles.
