BINDER CONTAINING SUBSTITUTED BENZENES AND NAPHTHALENES FOR PRODUCING CORES AND MOLDS FOR METAL CASTING, MOLD MATERIAL MIXTURE, AND METHOD |
摘要 |
<p>A binder for mold material mixtures is a four-component material. It contains at least one phenolic resin component, at least one isocyanate component, at least one alkyl/alkenyl benzene and at least one dialkylated and/or dialkenylated naphthalene. The phenolic resin component acts as the polyol component and contains phenolic resin obtainable from the reaction between a phenol compound and an aldehyde compound. The isocyanate component contains at least one polyisocyanate with at least two NCO groups per molecule. The alkyl/alkenyl benzene has a boiling point above 250° C. The dialkylated and/or dialkenylated naphthalene has a boiling point above 270° C.</p> |
