MODIFIED WATER-ABSORBENT RESIN PARTICLES |
摘要 |
Modified water-absorbent resin particles produced by treating particles of a substantially water-insoluble water-absorbent resin (A) comprising a cross-linked polymer of an ethylenically unsaturated monomer containing acrylic acid and/or acrylate salt as the principal constituent with an organopolysiloxane (B) which is liquid at ordinary temperature, wherein: (1) components (A) and (B) are in a state mixed or reacted with each other; (2) at least 95 wt.% of the particles of component (A) have diameters of 10-1,000 mu m; and (3) the weight ratio of component (A) to component (B) is 100/(0.001-5). As compared with conventional water-absorbent resins, the invention resin particles are improved in blocking resistance after moisture absorption and prevention of dusting, and at least retain the absorption characteristics of water-absorbent resins, such as absorption under normal pressure, absorption under applied pressure, and surface dryness after moisture absorption. Therefore the particles are suitable for various uses wherein water-absorbent resin particles are utilized, especially for hygienic articles, such as paper diaper, sanitary napkin and pad for incontinence, and absorbent patch. |
