Abstract

PROCEDIMIENTO PARA LA OBTENCION DE ESPUMAS DE POLIURETANO. PROCEDIMIENTO PARA LA OBTENCION DE ESPUMAS DE POLIURETANO A PARTIR DEL POLIOL E ISOCIANATO Y EN PRESENCIA DE UN CATALIZADOR, UN AGENTE DE SOPLADO Y OPCIONALMENTE DE ADITIVOS CARACTERIZADO PORQUE SE SUSTITUYE HASTA UN 60 POR CIENTO DEL POLIOL NECESARIO POR UNA RESINA NATURAL TAL COMO COLOFONIA O MIERA PREVIAMENTE LICUADA POR ADICION DE UN DISOLVENTE ADECUADO TAL COMO DIETILENGLICOL O ESENCIA DE TREMENTINA. EL PROCEDIMIENTO COMPRENDE BASICAMENTE LAS ETAPAS DE LICUAR EN CALIENTE UNA RESINA NATURAL POR ADICION DE UN DISOLVENTE ADECUADO Y MEZCLARLA CON POLIOL AL OBJETO DE OBTENER UNA MEZCLA "POLIOL-COLOFONIA LICUADA" QUE CONTIENE PREFERENTEMENTE UN 60 POR CIENTO DE COLOFONIA Y UN 40 POR CIENTO DE POLIOL. POSTERIORMENTE DICHA MEZCLA REACCIONA CON UN ISOCIANATO EN PRESENCIA DEL CATALIZADOR, EL AGENTE DE SOPLADO Y LOS ADITIVOS CORRESPONDIENTES. COMO AGENTE DE SOPLADO PUEDE UTILIZARSE AGUA PARA EVITAR LOS PROBLEMAS MEDIOAMBIENTALES ASOCIADOSCON UN CFC''S, AGENTES DE SOPLADO HABITUALMENTE UTILIZADOS EN ESTE TIPO DE PROCEDIMIENTOS. LA ESPUMA DE POLIURETANO PUEDE UTILIZARSE COMO AISLANTE TERMICO O ACUSTICO Y EN LA FABRICACION DE SILLONES Y COMPONENTES DE AUTOMOVILES.PROCEDURE FOR OBTAINING POLYURETHANE FOAMS. PROCEDURE FOR THE OBTAINING OF FOAMS OF POLYURETHANE FROM POLIOL AND ISOCIANATO AND IN THE PRESENCE OF A CATALYST, A BLOWING AGENT AND OPTIONALLY OF ADDITIVES CHARACTERIZED BY UP TO 60 PERCENT OF THE NECESSARY POLYOL BY A NATURAL RESIN PREVIOUSLY LIQUEFIED BY ADDITION OF A SUITABLE SOLVENT SUCH AS DIETHYLENE GLYCOL OR TREMENTINE ESSENCE. THE PROCEDURE BASICALLY UNDERSTANDS THE STAGES OF HOT BLENDING A NATURAL RESIN BY ADDITION OF A SUITABLE SOLVENT AND MIXING IT WITH POLIOL IN ORDER TO OBTAIN A MIX "POLIOL-COLOPHONY LIQUEFIED BY 40 PERCENT OF 40 PERCENT POLYOL. LATER THESE MIXTURES REACT WITH AN ISOCYANATE IN THE PRESENCE OF THE CATALYST, THE BLOWING AGENT AND THE CORRESPONDING ADDITIVES. AS A BLOWING AGENT WATER CAN BE USED TO AVOID THE ENVIRONMENTAL PROBLEMS ASSOCIATED WITH A CFC''S, BLOWING AGENTS USUALLY USED IN THIS TYPE OF PROCEDURES. POLYURETHANE FOAM CAN BE USED AS A THERMAL OR ACOUSTIC INSULATOR AND IN THE MANUFACTURE OF ARMCHAIRS AND COMPONENTS OF AUTOMOBILES.
