Abstract

Manufacturing process of artificial stone elements, characterized essentially because it consists in the succession of the following operative phases: A) kneading a polyester resin together with fillers in the form of aggregate elements at a temperature between 15 degrees and 35 degrees centigrade, until obtaining a pasty mass, with an approximate density of 1.5 to 4, with previous incorporation of an accelerant, such as cobalt naphthene or similar, B) obtain another paste-like mass based on polyester resin and an accelerant such as cobalt naphthene or similar, C) include, in a proportion of 0.2 to 3%, a catalyst, such as methyl ethyl ketone peroxide in each of the two masses described above and immediately before casting or pouring into the corresponding mold, D) pouring the dough described in a) into the mold directly or above the dough described in b) previously deposited in the mold, E) deposit, on the mass described in a) and before this mass has gelled, a layer that is intimately linked to it, then proceeding to clean this layer of small remnants, F) pour over the layer described in e) a layer of mortar, G) proceed to set the mortar, with a waiting time of 2 hours at room temperature, then sip it dry from 30 degrees to 100 degrees celsius last 8 hours and finally 12 hours at room temperature or, subjecting it from the beginning of the water vapor setting process for one hour at 100 degrees centigrade.
