Abstract

LA INVENCION PROPONE EL SIGUIENTE METODO PARA PRODUCIR MASAS DE FUSION REACTIVAS, LAS CUALES SON ESPECIALMENTE UTILES COMO ADHESIVOS DE FUSION EN CALIENTE: A) POLIMEROS O MEZCLAS DE POLIMEROS (A) APROPIADOS QUE PUEDEN FUNDIR, HIDROXI O AMINO-FUNCIONALES, QUE A TEMPERATURAS POR ENCIMA DE 40 (GRADOS) C PASAN AL ESTADO LIQUIDO, SON MEZCLADOS DE MODO NO HOMOGENEO CON B) POLIISOCIANATOS (B) EN FORMA DE POLVO, SOLIDOS, DESACTIVADOS SUPERFICIALMENTE, O UNA SUSPENSION DE TALES ISOCIANATOS (B) EN UN LIQUIDO PORTADOR DE BAJA VOLATILIDAD, C) EN PROPORCIONES APROXIMADAMENTE ESTEQUIOMETRICAS, A UNA TEMPERATURA DE AL MENOS 40 (GRADOS) C EN UN MEZCLADOR ESTATICO, DE TAL MODO QUE LA MEZCLA RESULTANTE DE SUSTANCIAS PRESENTA ZONAS PARCIALES EN LAS CUALES LA RELACION (1) DE POLIMERO (A) A (2) ISOCIANATO SOLIDO (B) Y AGENTE DESACTIVANTE (C), ES DIFERENTE DE LA RELACION MEDIA DE ESTAS SUSTANCIAS O MEZCLAS DE ELLAS EN LA MEZCLA TOTAL DE SUSTANCIAS. D) LA MEZCLA NO HOMOGENEA ES EXTRAIDA EN UNA FORMA APROPIADA PARA EL USO PRETENDIDO Y SOLIDIFICADA POR ENFRIAMIENTO HASTA POR DEBAJO DEL PUNTO DE ABLANDADO DE LA MEZCLA. ESTAS MASAS DE FUSION REACTIVAS PREFORMADAS O EN TODO CASO NO FORMADAS, SOLIDAS, SE PUEDEN ALMACENAR A TEMPERATURA AMBIENTE Y CONSERVAN SU TERMOREACTIVIDAD LATENTE.
