    摘要: The present invention relates to foundry binder systems forming a curable polyurethane with a catalytically effective amount of a curing catalyst, comprising at least one phenolic resin component comprising at least: a phenolic resin and a solvent of triacetin type and a polyisocyanate component. The invention also relates to foundry mixtures prepared from the binder and an aggregate, to foundry forms such as cores and molds prepared via the no-bake or cold-box processes, and also to the respective processes. The foundry forms obtained by the present invention are especially used for manufacturing metallic components, especially for the casting of metallic components.

    摘要: The present invention relates to a production process for a phenols novolac resin obtained by reacting phenols with formaldehydes, wherein they are reacted in the presence of a metal compound used as a catalyst for the reaction described above, and a chelating agent is further added in order to deactivate a catalytic action of the metal compound and a resin-coated sand prepared by using the above phenols novolac resin. It is possible to provide a process for producing a phenols novolac resin having an ortho rate of 30 to 60%, suitably 40 to 55% at a good yield (70% or more) and a resin-coated sand having a high curing property prepared by using the above phenols novolac resin.

    摘要: The binder coated refractories comprises the refractory aggregates and the solid-form coating layer which comprises the sugar group as the binder and which is provided to the surface of the refractory aggregates. According to this, the sugar group is used as the binder for bonding the refractory aggregates. Further, even if the sugar group is thermally decomposed, the sugar group emits the carbon dioxide and the water. Therefore, there is little likelihood of emitting the harmful gas. Therefore, it is possible to reduce the environmental pollution. Further, the sugar group is thermally decomposed easily. Therefore, it is possible to manufacture the casting mold having the good breaking property.
