Abstract

METODO PARA PREPARAR UN ELASTOMERO MOLDEADO POR INYECCION EN REACCION.CONSISTE EN INYECTAR DOS CORRIENTES; LA PRIMERA LLEVA POLIETERES CON AMINOS TERMINALES, UN EXTENSOR DE CADENA CON AMINOS TERMINALES Y UN AGENTE DE SEPARACION DE MOLDE, Y LA SEGUNDA LLEVA POLIISOCIANATO AROMATICO, A TRAVES DE UNA MAQUINA MIR A UNA CAVIDAD DE MOLDE, PARA OBTENER UN ELASTOMERO (MIR) QUE SE SACARA DEL MOLDE SIN AGENTE DE SEPARACION APLICADO EXTERNAMENTE. LOS POLIETERES CON AMINOS TERMINALES SON POLIETERES POLIOLES CON AMINOS TERMINALES PRIMARIOS O SECUNDARIOS CON UN PESO MOLECULARPROMEDIO MAYOR DE 1.500 QUE TIENEN UNA FUNCIONALIDAD DE 2 A 6 Y UN PESO EQUIVALENTE DE AMINO DE 750 A 4.000, LOS EXTENSORES DE CADENA SON DIAMINAS AROMATICAS 1-METIL-3,5-DIETIL-2,4- DIAMINOBENCENO, 1-METIL-3,5-DIETIL-2,6-DIAMINOBENCENO Y OTROS, LOS POLIISOCIANATOS SON DIISOCIANATOS DE 1-FENILO, DIISOCIANATO DE 2,6-TOLUENO Y OTROS Y EL AGENTE DE SEPARACION UN DIMETILSILOZANO CON GRUPOS ACIDOS ORGANICOS.
