Abstract (en)
[origin: US2004238156A1] A water-dispersible casting mould, particularly a core, for the manufacture of castings is proposed. The mould contains a water-insoluble, particulate material, such as moulding sand, a binder, which has a first binder component based on a condensed phosphate, and optionally a flux. In order to ensure an increased flexural strength and abrasion resistance, there is a second binder component based on polyamines. It is also possible to provide a flux based on alkali metal carbonate, which gives the mould an increased thermal stability. The invention also relates to a method for the manufacture of such a mould, in that the aforementioned components are mixed, accompanied by the addition of water, the mixture is moulded and at least part of the added free water is removed.
