Abstract

PROCEDIMIENTO DE OBTENCION DE PLASTICOS EXPANDIDOS RESILIENTES A BASE DE UN PRODUCTO DE CONDENSACION DE MELAMINA-FORMALDEHIDO. CONSISTE EN ESPUMAR UNA SOLUCION O DISPERSION ACUOSA QUE CONTIENE UN PRECONDENSADO DE MELAMINA-FORMALDEHIDO, UN EMULSIONANTE, UN AGENTE DE EXPANSION VOLATIL Y UN ENDURECEDOR. EL PLASTICO ESPUMADO SE CALIENTA DE 1 A 180 MINUTOS A UNA TEMPERATURA COMPRENDIDA ENTRE 120 Y 300 GRADOS. ANTES O DESPUES DEL TRATAMIENTO TERMICO SE COMPRIME EL PLASTICO EXPANDIDO UNA O VARIAS VECES POR UN 40 HASTA 90 POR 100 DE ALTURA ORIGINAL Y SE DEJA RECUPERAR OTRA VEZ.
