VERFAHREN ZUM HERSTELLEN EINER SANDFORM |
摘要 |
An acid-hardenable binder system for producing a sandcasted mould by means of the generative 3D printing method is disclosed. According to the invention, a high mechanical strength and at the same time a low stripping behaviour of the sandcasted mould during the casting is due to the fact that the resin component of the binder system contains a nitrogen-containing compound comprising a nitrogen content of 4 wt.% in relation to the total amount of resin and an aryl sulfonic acid as a hardener having a proportion by weight of 30 to 50 % of the total amount of resin, an aromatic alcohol being provided for the cleaning of the printing nozzles of the resin. |
