Abstract
(EN)
It is intended to provide a water-absorbing resin composition in which the liquid diffusion properties (i.e., meaningful characteristics in practice) have been largely improved without worsening the fundamental water-absorbing performance, productivity and so on as a water-absorbing resin material to be used as a water-absorbing material in paper diapers, etc. A method of producing a water-absorbing resin composition which involves the step of mixing a water-absorbing resin A with inorganic microparticles B having been irradiated with ultraviolet light so that the amount of the inorganic microparticles B is controlled to from 0.01 to 10 parts by weight per 100 parts by weight of the water-absorbing resin A. Thus, a water-absorbing resin composition having a liquid diffusion velocity (LDV) of from 2.0 to 10 mm/s can be produced.

La présente invention concerne une composition de résine hydro-absorbante dans laquelle les propriétés de diffusion dans un liquide (à savoir, les caractéristiques significatives dans la pratique) ont été en grande partie améliorées sans altérer la performance hydro-absorbante fondamentale, la productivité et ainsi de suite en tant que matériau en résine hydro-absorbant utilisé en tant que matériau hydro-absorbant dans les couches-culottes en papier, etc. La présente invention concerne un procédé de production d'une composition de résine hydro-absorbante qui implique l'étape de mélanger une résine hydro-absorbante A à des microparticules inorganiques B ayant été irradiées par des rayons UV de sorte que la quantité de microparticules inorganiques B soit régulées dans une gamme de 0,01 à 10 parties en poids pour 100 parties en poids de la résine hydro-absorbante A. Ainsi, on peut produire une composition de résine hydro-absorbante ayant une vitesse de diffusion dans un liquide (VDL) dans la gamme de 2,0 à 10 mm/s.
