Patent number: 12187860Abstract: The present invention addresses the problem of providing; a water absorbent resin powder having a reduced amount of fine powder generated and a reduced amount of fine powder recovered; and a production method for the water absorbent resin. The production method of the present invention includes a drying step and a fine powder granulation step. The drying step is for obtaining a dried polymer by drying a particulate water-containing gel crosslinked polymer which is obtained using an acid group-containing unsaturated monomer as a main component. The fine powder granulation step is for obtaining a fine powder granulated product by adding a binder and an adhesion control agent to a fine powder made of a water absorbent resin. In this production method, the obtained fine powder granulated product is recovered in the drying step or in any step before the drying step.Type: GrantFiled: May 16, 2019Date of Patent: January 7, 2025Assignee: NIPPON SHOKUBAI CO., LTD.Inventors: Tsuyoshi Yorino, Naoki Katakura, Hiroki Hayashi, Sumito Kumagai, Masahumi Inoue, Tomoyuki Arake, Mai Sato, Ryota Wakabayashi, Yoshihiro Shobo, Shin-ya Katsube, Yoshifumi Adachi, Satoshi Matsumoto
