Abstract (en)

[origin: WO2019002452A1] A description is given of a method for producing a moulding material mixture or for producing a moulding material mixture and a moulded body thereof, preferably casting moulds or cores, for use in the casting industry, wherein the moulding material mixture comprises a moulding base material and a solution or dispersion comprising lithium-containing sodium silicate, comprising the steps of: (1) producing or providing a kit at least comprising as separate components: (K1) an aqueous solution or dispersion comprising sodium silicate and (K2a) a first sodium-silicate-free solution or dispersion comprising lithium ions dissolved in water and preferably (K2b) a second sodium-silicate-free solution or dispersion, preferably comprising lithium ions dissolved in water of a lower concentration than in component (K2a), and then (2) producing a mixture of the moulding base material with a proportion of the component (K1) and with a proportion of the component (K2a) and also optionally with a proportion of the component (K2b). Also described is an aforementioned kit, in particular for use in the method according to the invention. Also specified is an installation for producing an intermediary solution or dispersion, comprising lithium-containing sodium silicate for use in the production of a moulding material mixture or for the production of a moulding material mixture and a moulded body thereof.
