3 PRODUCTION METHOD FOR POROUS BODY THREE-DIMENSIONAL MESH-LIKE POROUS BODY LIQUID FILTER AND LIQUID-ABSORBING SPONGE

摘要

The present invention relates to a method for producing a three-dimensional networked porous body made of a thermoplastic elastomer, which is capable of producing a homogeneous porous body safely and easily stably with less problems such as an influence on the working environment and an increase in cost, , A liquid filter having excellent filtration performance using the three-dimensional network porous body, and a liquid-absorbing sponge having excellent liquid-absorbing properties, wherein a kneaded product of a thermoplastic elastomer, inorganic salt particles and polyhydric alcohol is defoamed And a step of solidifying the obtained molded product and then extracting the inorganic salt particles by water extraction and drying the mixture, wherein the blending amount of the polyhydric alcohol in the composition is uniformly mixed with the thermoplastic elastomer during thermal melting of the thermoplastic elastomer A process for producing a porous material having a maximum amount of alcohols of 55% by mass or more, To provide a three-dimensional network porous body, and a liquid filter, the liquid-absorbing sponge using this three-dimensional network porous body is produced.
