A cold-curing binder; and a process for producing a phenolic resin molding with the binder. Also provided are: a porous ceramic molding obtained by curing the binder and a ceramic without heating the mixture and then burning the cured mixture obtained; and a process for producing the porous ceramic molding. The cold-curing binder comprises as major ingredients a tri- or tetrafunctional phenol compound having one or two electron-donating groups on the phenolic benzene ring, a crosslinking agent, and a catalyst.
La présente invention concerne un liant durcissant à température ambiante et un processus de production de moulage de résine phénolique avec ce liant. Cette invention concerne aussi un moulage de céramique poreuse obtenu par durcissement de ce liant et une céramique obtenue sans chauffer le mélange puis par cuisson du mélange durci obtenu et, un processus de production de moulage de céramique poreuse. Ce liant durcissant à température ambiante comprend comme substances principales un composé phénol tri ou tétrafonctionnel possédant un ou deux groupes donneurs d'électron sur le cycle benzène phénolique, un agent de réticulation et un catalyseur.
