METHOD OF PRODUCING POROUS MATERIAL HAVING OPEN PORES |
摘要 |
A method of producing a porous material having open pores comprises stirring a mixture comprising (i) an epoxy compound having at least one epoxy ring in a molecule, (ii) a hardener capable of reacting with the epoxy compount to harden the epoxy compound, (iii) a filler and (iv) water to form an emulsion slurry having a low viscosity and containing the soluble salts uniformly dispersed therein, casting the resulting emulsion slurry in a water impermeable mold and then hardening the slurry while maintaining the water content thereof, and wherein the soluble salts are added to the mixture. The method makes it possible to produce a large scale porous material having open pores and a complicated shape whose shrinkage factor during hardening and water and air permeabilities are controlled to desired levels respectively while scattering thereof is reduced.
