Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE MONTAJE POR ADHESION DE PIEZAS DE MATERIAL SINTETICO PIROLIZABLE, PARA CONSTITUIR UN MOLDE QUE SIRVE DE MODELO PERDIDO PARA EL MOLDEADO DE METALES DEL TIPO CON MODELO PERDIDO. SE PULVERIZA UNA COLA EN EMULSION ACUOSA SOBRE LAS PARTES QUE HAY QUE ADHERIR. SE PULVERIZA UNA COLA A BASE DE POLIURETANO EN EMULSION ACUOSA, Y A CONTINUACION SE SECA LA COLA EVAPORANDO EL AGUA POR CALENTAMIENTO. EL MATERIAL SINTETICO PIROLIZABLE ES POLIESTIRENO EXPANSIONADO Y LA COLA COMPRENDE 100 PARTES EN PESO DE UNA EMULSION ACUOSA DE POLIURETANO, OCASIONALMENTE HASTA EL 50 % EN PESO DE UNA EMULSION ACUOSA DE UN COPOLIMERO ETILENO/ACETATO DE VINILO O DE UN COPOLIMERO VINILICO, ACRILICO O VINILACRILICO. SE SECA LA COLA A UNA TEMPERATURA COMPRENDIDA ENTRE APROXIMADAMENTE 50õC Y 80õC, DURANTE UNA DURACION DE APROXIMADAMENTE 8 Y 3 MINUTOS. APLICACION EN LA FABRICACION DE PIEZAS METALICAS MOLDEADAS.THE INVENTION REFERS TO A MOUNTING PROCEDURE FOR THE ADHESION OF PIECES OF SYNTHETIC MATERIAL, TO CONSTITUTE A MOLD THAT IS SERVED OF LOST MODEL FOR MOLDING METALS OF THE TYPE WITH LOST MODEL. A TAIL IN WATER EMULSION IS SPRAYED ON THE PARTS TO BE ADHERED. A POLYURETHANE-BASED TAIL IN SPRAY EMULSION IS SPRAYED, AND THEN THE TAIL IS DRIED EVAPORATING THE WATER BY HEATING. THE POTENTIAL SYNTHETIC MATERIAL IS EXPANSIONED POLYSTYRENE AND THE TAIL INCLUDES 100 PARTS BY WEIGHT OF A WATERPROOF EMULSION OF POLYURETHANE, OCCASIONALLY UP TO 50% BY WEIGHT OF A WATERY EMULSION OF AN ETHYLENE VINYL OIL VINYL ACRYLINIC COPYLIMINUM . THE TAIL IS DRIED AT A TEMPERATURE INCLUDED BETWEEN APPROXIMATELY 50ºC AND 80ºC, DURING A DURATION OF APPROXIMATELY 8 AND 3 MINUTES. APPLICATION IN THE MANUFACTURE OF MOLDED METAL PARTS.
