  • Patent number: 10773297
    Abstract: A moulding material mixture with at least one refractory material and water glass as an inorganic binding agent is used for producing casting moulds. The binding agent is cured with the aid of a carbonyl compound that has a molecular weight greater than 88 g/mol and less than 200 g/mol and a boiling point at 1013 hPa greater than 20° C. and less than 200° C. The at least one carbonyl compound is introduced into the gas phase, or carried with the gas phase. The at least one carbonyl compound has the formula R1R2C?O, where R1 is H or a C1 or C2 alkyl and R2 is a carboxyl group R—C(?O)—O— bonded via the oxygen atom, where R is a C1 to C3 hydrocarbon.

  • Publication number: 20170320128
    Abstract: The invention relates to a binder, which contains water glass and further a phosphate or a borate or both. The invention further relates to a method for constructing molds and cores layer by layer, the molds and cores comprising a construction material mixture, which at least comprises a refractory molding base material, and the binder. In order to produce the molds and cores layer by layer in 3-D printing, the refractory molding base material is applied layer by layer and is selectively printed with the binder layer by layer, and consequently a body corresponding to the molds or cores is constructed and the molds or cores are released after the unbonded construction material mixture has been removed.
