Abstract

PROCEDIMIENTO PARA LA OBTENCION DE PLASTICOS CELULARES O COMPACTOS A PARTIR DE DOS O MAS COMPONENTES QUE REACCIONAN ENTRE SI. EN UNA PRIMERA ETAPA SE HACEN REACCIONAR ENTRE SI LOS SIGUIENTES COMPONENTES: A) POLIISOCIANATOS ORGANICOS; B) COMPUESTOS POLIHIDROXILO DE ALTO PESO MOLECULAR; C) ALARGADORES DE CADENA DE BAJO PESO MOLECULAR, RETICULANTES TALES COMO DIOLES ALIFATICOS Y/O ALCANOLAMINAS DE PESO MOLECULAR ENTRE 60 Y 300, PRESENCIA DE CATALIZADORES; D) DISOLVENTES AROMATICOS (BENCENO, TOLUENO, XILENOS O ETERES Y SUS MEZCLAS) Y E) PRODUCTOS AUXILIARES Y/O ADITIVOS, TALES COMO TENSIOACTIVOS, COLORANTES IGNIFUGOS, BACTERIOSTATICOS, ETC. ESTOS COMPONENTES SE INTRODUCEN EN UNA ZONA DE MEZCLADO Y A LA SALIDA SE LES AGREGA AIRE CALENTADO A UNA TEMPERATURA ENTRE 280 Y 320GC Y A UNA PRESION ENTRE 2,5 Y 3,2 BARES. SE OBTIENE UN RECUBRIMIENTO UNIFORME, IMPIDIENDOSE EL ESCURRIMIENTO EN SUPERFICIES VERTICALES.
