    摘要： A method of preparing foundry shapes, e.g. molds and cores, by mixing a foundry aggregate with a foundry binder, shaping the mixture in a pattern, curing the mixture, and removing the mixture from the pattern. The foundry binder is a phenolic urethane binder that utilizes a phenolic resin prepared by reacting a phenol, an aldehyde, bisphenol-A-tar, and a divalent metal catalyst.

    摘要： 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.

    摘要： The invention relates to a molding mixture for producing casting molds for metalworking, a process for producing casting molds, casting molds obtained by the process and also their use. To produce the casting molds, a refractory mold raw material and a binder based on water glass are used. A proportion of a particulate metal oxide selected from the group consisting of silicon dioxide, aluminum oxide, titanium oxide and zinc oxide is added to the binder, particular preference being given to using synthetic amorphous silicon dioxide. The molding mixture contains a phosphate as essential constituent. The use of phosphate can improve the mechanical strength of casting molds at high thermal load.
