Abstract

La presente se refiere a sistemas aglutinantes para fundición, que forman un poliuretano curable con una cantidad cataliticamente eficaz de un catalizador de curado, que comprende al menos un componente de resma fenólica que comprende al menos: una resina fenólica y un solvente de tipo triacetina para la resina fenólica y un componente de poliisocianato. La presente también se refiere a mezclas para fundición preparadas a partir del aglutinante y un árido, a formas para fundición tales como machos y moldes preparados a través de procesos sin horneado o de caja fría, y también a los procedimientos respectivos. Las formas para fundición obtenidas a través de la presente se utilizan especialmente para la fabricación de componentes metálicos, en especial, para moldear componentes metálicos.This refers to smelter binder systems, which form a curable polyurethane with a catalytically effective amount of a curing catalyst, comprising at least one phenolic ream component comprising at least: a phenolic resin and a triacetin type solvent for the phenolic resin and a polyisocyanate component. This also refers to foundry mixes prepared from the binder and an aggregate, to foundry forms such as males and molds prepared through unbaked or cold box processes, and also to the respective procedures. The forms for casting obtained herein are especially used for the manufacture of metal components, especially for molding metal components.
