Abstract

PROCEDIMIENTO PARA PREPARAR CUERPOS DE MOLDEO A BASE DE POLIMERIZADOS DE ESTIRENO, EN PARTICULAR A BASE DE POLIMERIZADOS DE ESTIRENO PARTICULADOS MODIFICADOS, QUE CONTIENEN UN AGENTE EXPANSIVO. COMPRENDE LAS SIGUIENTES ETAPAS: PRIMERA, SE MODIFICA UN POLIMERIZADO DE ESTIRENO EN FORMA DE PARTICULAS DE 0,1 A 6 MM. DE DIAMETRO, QUE CONTIEN UN AGENTE EXPANSIVO, MEDIANTE RECUBRIMIENTO SUPERFICIAL DE DICHAS PARTICULAS CON 0,05 A 1 POR 100 EN PESO DE UN ETER DIALQUILO DE GLICERINA; SEGUNDA, SE PRE-ESPUMAN LAS PARTICULAS DE POLIESTIRENO MODIFICADAS MEDIANTE APLICACION DE UNA CORRIENTE DE VAPOR, CON AGITACION CONTINUA; Y POR ULTIMO, SE UNEN LAS PARTICULAS EN UN MOLDE DE BLOQUE MEDIANTE TRATAMIENTO CON VAPOR, DURANTE UN TIEMPO DE VEINTE A CINCUENTA SEGUNDOS APROXIMADAMENTE.
