Abstract

SE DESCRIBE UNA PIEZA DE ALIMENTADOR EVENTUALMENTE A BASE DE UNA MEZCLA DE COMPONENTES CON ACCION AISLANTE Y/O EXOTERMICA ASI COMO ADITIVOS HABITUALES UNIDOS MEDIANTE UN AGLUTINANTE A UN ARTICULO MOLDEADO. PARA ELLO SE UTILIZA COMO AGLUTINANTE UN POLIURETANO, ENTRE CUYOS COMPONENTES SE ENCUENTRAN UNA RESINA FENOLICA CON GRUPOS OH LIBRES Y UN POLIISOCIANATO, DE LOS QUE COMO MINIMO UNO ESTA DISUELTO EN UN DISOLVENTE COMPUESTO EN SU TOTALIDAD O EN SU MAYOR PARTE POR UN ESTER METILICO DE ACEITE VEGETAL. ES ACONSEJABLE QUE AMBOS COMPONENTES DEL AGLUTINANTE ESTEN DISUELTOS EN ESTER METILICO DEL ACEITE VEGETAL, PREFERENTEMENTE ESTER METILICO DE ACEITE DE COLZA. PARA FABRICAR ESTAS PIEZAS DE ALIMENTADOR SE MEZCLAN LA MEZCLA DE COMPONENTES CON ACCION AISLANTE Y/O EXOTERMICA Y EVENTUALMENTE ADITIVOS HABITUALES CON LA RESINA FENOLICA DISUELTA Y EL POLIISOCIANATO DISUELTO, SE MOLDEAN Y SE ENDURECEN MEDIANTE GASIFICACION CON UNA AMINA TERCIARIA.
