Abstract
Liants thermodurcissables à base de résines phénol-formaldéhyde pour matières à mouler à base de sable ou d'autres matières de charge inertes. Les liants, à l'état de solution hydroorganique à une teneur en matières sèches de 50 à 75 %, contiennent en outre une huile végétale hydroxylée du type de l'huile de ricin ou un ester hydroxylé analogue préparé par synthèse et/ou un acide gras contenant des groupes hydroxy libres. Les liants selon l'invention servent à revêtir des sables ou autres matières de charge inertes qu'on utilise ensuite pour des moulages, par exemple dans la préparation de noyaux et coquilles de fonderie.Thermosetting binders based on phenol-formaldehyde resins for molding materials based on sand or other inert fillers. The binders, in the form of a hydroorganic solution with a dry matter content of 50 to 75%, additionally contain a hydroxylated vegetable oil of the castor oil type or a similar hydroxylated ester prepared by synthesis and / or an acid fatty containing free hydroxy groups. The binders according to the invention are used to coat sands or other inert fillers which are then used for moldings, for example in the preparation of foundry cores and shells.
