Abstract
Process for obtaining a binder that allows the quick setting at will of the melting cores within their boxes, consisting essentially of a chemically prepared drying oil, to which is added, at the time of preparation of the mixture, an appropriate catalyst, which will cause the setting, whose speed can be varied at will, thus obtaining with the drying oil used a binder that, mixed with sand, allows to regulate the duration of setting of the cores, which can be accelerated to less 40 minutes, and this procedure is carried out by preparing a mixture of sand in which this, of siliceous nature and in a dry state, is poured into a current mixer, adding 1 to 2% of drying oil, which is it adds from 5 to 30% of catalyst in relation to the indicated oil, filling with the resulting sand the boxes of cores or mold chassis, which are left in i hold the time necessary for the setting of the mixture, the mixing duration having a great influence on the setting time, so that the longer the material is in the mixer, the faster the cured will result.
