Abstract (en)

[origin: WO2018002129A1] The invention relates to an aqueous alkaline binder composition for curing with carbon dioxide gas, comprising a phenol group with negatively charged or uncharged phenol-aldehyde resin which is selected from the group consisting of resols and mixtures comprising one or more resols and one or more novolaks, an oxyanion, selected from the group consisting of borate ions, aluminate ions, stannate ions, zirconate ions, titanium ions and mixtures thereof, for forming a stable complex with the resol phenol-aldehyde resin, wherein the total molar weight of the phenol group of the phenol-aldehyde resin in the aqueous alkaline binder composition is in the region of 1 - 3 mol/kg with respect to the total mass of the aqueous alkaline binder composition and wherein the phenol-aldehyde resin has an average molecular weight (mw) in the region of 750 - 1200g/mol, determined by the gel permeation chromatography. The invention also relates to a corresponding use, a moulding mixture for producing a foundry shape and to a corresponding method for producing a foundry shape and a corresponding foundry shape.
