Abstract

L'INVENTION CONCERNE LA FONDERIE. LE LIANT POUR SABLE DE MOULAGE CONFORME A L'INVENTION EST DU TYPE A BASE DE RESINE UREE-FORMOL, AVEC UN MODIFICATEUR REGULATEUR DU POUVOIR LIANT, ET EST CARACTERISE EN CE QU'A TITRE DE MODIFICATEUR ON UTILISE UNE EMULSION CONTENANT UNE FRACTION LOURDE DE GOUDRON DE SCHISTES BITUMINEUX AYANT UNE MASSE VOLUMIQUE AU MOINS EGALE A 1,01GCM, UN SOLVANT ORGANIQUE CAPABLE DE DISSOUDRE LES COMPOSES DE CARBONE CONTENUS DANS LADITE FRACTION DE GOUDRON, UN EMULSIFIANT ET DE L'EAU, LESDITS CONSTITUANTS ETANT INTRODUITS DANS DES PROPORTIONS PERMETTANT D'OBTENIR UNE EMULSION HOMOGENE DU PREMIER GENRE, DU TYPE "HUILE DANS L'EAU". L'INVENTION PERMET NOTAMMENT DE CONFERER AU LIANT UNE HAUTE RESISTANCE A LA CHALEUR ET UNE HAUTE RESISTANCE MECANIQUE SANS ENTRAINER UNE AUGMENTATION SENSIBLE DE SON PRIX DE REVIENT.THE INVENTION CONCERNS THE FOUNDRY. THE BINDER FOR MOLDING SAND ACCORDING TO THE INVENTION IS OF THE UREE-FORMOL RESIN-BASED TYPE, WITH A BINDING POWER REGULATING MODIFIER, AND IS CHARACTERIZED AS A MODIFIER, AN EMULSION CONTAINING A HEAVY FRACTION OF BINDER IS USED. BITUMINOUS SHALE TAR HAVING A MASS BY VOLUME AT LEAST OF 1.01GCM, AN ORGANIC SOLVENT CAPABLE OF DISSOLVING THE CARBON COMPOUNDS CONTAINED IN THE SAID FRACTION OF TAR, AN EMULSIFIER AND WATER, THE SAID CONSTITUENTS MAY BE INTRODUCED INTO SUCH '' OBTAIN A HOMOGENEOUS EMULSION OF THE FIRST KIND, OF THE "OIL IN WATER" TYPE. THE INVENTION MAKES IN PARTICULAR ENABLING THE BINDER A HIGH HEAT RESISTANCE AND A HIGH MECHANICAL STRENGTH WITHOUT CAUSING A SIGNIFICANT INCREASE IN ITS COST PRICE.
