摘要： As water-absorbing resin materials used, for example, as water-absorbing materials of paper diapers, the present invention realizes a water-absorbing resin composition whose basic water-absorbing performances, productivity, etc. are not spoiled but whose liquid diffusibility that is a practically important characteristic is improved drastically. A method for manufacturing the water-absorbing resin composition of the present invention includes the step of mixing the water-absorbing resin A and the inorganic fine particle B, which has been irradiated with ultraviolet rays, on condition that the amount of the inorganic fine particle B is from 0.01 part by weight to 10 parts by weight when the amount of the water-absorbing resin A is 100 parts by weight. Thus, it is possible to manufacture the water-absorbing resin composition whose liquid distribution velocity (LDV) is from 2.0 mm/s to 10 mm/s.

摘要： A method for surface crosslinking water-absorbing resin of the present invention includes a step (1) of obtaining a wet mixture, a step (2) of obtaining a dried particulate composition, and a step (3) of carrying out a surface crosslinking reaction. With this, since a processing time of each step becomes short, it is possible to mass produce the water-absorbing resin having excellent physical properties. Moreover, a method for manufacturing the water-absorbing resin of the present invention includes a modifying step and a cooling step. The modifying step and/or the cooling step are/is carried out by using stirring means including a rotation axis having a plurality of stirring boards, and the stirring means includes the stirring board having a specific thickness and/or a scraping blade having a specific shape. With this, it is possible to suppress the generation of the fine powder in the modifying step and/or the cooling step.
