Abstract

LE SYSTEME DE LIANT A BASE DE POLYURETHANE POUR DES MELANGES DE MATIERES DE MOULAGE POUR LA FABRICATION DE MOULES ET DE NOYAUX, COMPREND UN POLYISOCYANATE AVEC AU MOINS DEUX GROUPES NCO PAR MOLECULE ET POLYOL AVEC AU MOINS DEUX GROUPES OH PAR MOLECULE, PAR EXEMPLE UNE RESINE DE CONDENSATION COMPORTANT DES GROUPES OH, FORMANT LES PARTICIPANTS A LA REACTION, UNE AMINE TERTIAIRE OU UN LIANT ORGANOMETALLIQUE, FORMANT L'ACCELERATEUR, AINSI QU'UN DISSOLVANT. DANS CES ESTERS, LA COMPOSANTE ACIDE EST UN ACIDE DICARBOXYLIQUE ALIPHATIQUE COMPORTANT DE 6 A 12ATOMES DE CARBONE OU UN ACIDE BENZOLPOLYCARBOXYLIQUE COMPORTANT 3GROUPES COOH OU PLUS, ET LA COMPOSANTE ALCOOL EST UN ALCOOL ALIPHATIQUE, CYCLOALIPHATIQUE, ARYLALIPHATIQUE OU AROMATIQUE COMPORTANT DE 6 A 13ATOMES DE CARBONE.
