Abstract

LA PRESENTE PATENTE AFECTA A UN PROCESO DE PRODUCCION DE OBJETOS MOLDEADOS DOTADOS, A TRAVES DE UNA CAPA CON AL MENOS UNA ESTRUCTURA DE ESPUMA, DE UNA CAPA NO ESPUMADA, PRODUCIDA POR EL PROCESO "SLUSH - MOLDING", DE HOMO -, CO - O TERPOLIMERIZADO O POLIMERIZADO DE INJERTO DE CLORURO DE VINILO (CAPA COMPACTA). PARA PRODUCIR LA CAPA NO ESPUMADA SE PONE UN POLIMERIZADO DE CLORURO DE VINILO CON ABLANDADOR EN UN MOLDE POR PROCESO "SLUSH-MOLDING", Y SE GELATINIZA O SINTERIZA POR CALENTAMIENTO. TRAS LA FORMACION DE LA CAPA COMPACTA, SE SACA EVENTUALMENTE DEL MOLDE EL POLVO, PLASTISOL O PASTA USADO EN EXCESO Y QUE NO HA GELATINIZADO O SINTERIZADO. SEGUN LA PATENTE, TRAS LA SINTERIZACION O GELATINIZACION DE LA CAPA COMPACTA SE APLICA UN HOMO -, CO - O TERPOLIMERIZADO O POLIMERIZADO DE INJERTO DE CLORURO DE VINILO CON ABLANDADOR QUE CONTENGA AL MENOS UN PROPELENTE QUIMICO SINAGUA, POR EL PROCEDIMIENTO "SLUSH-MOLDING", USANDOSE PARA ESTA CAPA DE CIERRE UNA MEZCLA DE 100 PARTES DEL PESO DE POLIMERIZADO DE CLORURO DE VINILO, DETERMINADAS PARTES DE PESO DE AL MENOS UN ABLANDADOR (ABLANDADOR MONOMERO Y/O POLIMERO), AL MENOS UN ESTABILIZADOR Y/O KICKER PARA EL PROPELENTE (INCLUIDOS ANTIOXIDANTES), AL MENOS UN PROPELENTE O MEZCLA DE PROPELENTES QUIMICOS LIBRES DE AGUA Y AL MENOS UNA SUSTANCIA DE RELLENO O MEZCLA DE SUSTANCIAS DE RELLENO Y/O ADITIVOS
