El reactivo poliepóxido aromático comprende uno o más compuestos, cada uno de ellos que tiene una pluralidad de grupos funcionales epóxido. El reactivo poliepóxido aromático tiene al menos 2 grupos epóxido presentes en la molécula, y puede tener hasta 4 grupos epóxido presentes en la molécula.
Estos poliepóxidos se pueden obtener mediante la reacción de epiclorhidrina y alcoholes o aminas aromáticos poliméricos usando técnicas conocidas. Los alcoholes y aminas aromáticos adecuados son aquellos que contienen más de dos equivalentes de hidrógeno capaces de reaccionar con la epiclorhidrina.
Ejemplos de alcoholes aromáticos adecuados son resinas fenólicas de novolaca y poli(vinilfenoles). Ejemplos ilustrativos de fenoles polihídricos adecuados son 2,2-bis(4-hidroxifenil)propano, 2,2-bis(3-bromo-4-hidroxifenil)propano, 2,2-bis(3,5-dicloro-4-hidroxifenil)propano, 2,2-bis(3-cloro-4-hidroxifenil)propano, bis(4-hidroxifenil)-metano, bis(4-hidroxifenil)sulfona, bis(4-hidroxifenil)sulfuro, resorcinol, hidroquinona, resinas de novolaca de fenolformaldehído, y similares.
Ejemplos de aminas aromáticas adecuadas son 4,4-diaminodifenilenemetano, 4,4-diaminodifenilensulfona, 3aminobencilamina, 3-fenilendiamina y 4,4-diaminoazodifenileno. Una clase representativa de reactivo poliepóxido aromático de acuerdo conla invención tiene la fórmula estructural:
en la que R5 designa un radical orgánico aromático que tiene una valencia igual a la suma de "c" y "d", en la que la suma de "c" y "d" es igual o superior a 2 pero no superior o igual a 6 y en la que "d" es igual o superior a 2 pero inferior o igual a 6. El término "aromáticos" engloba grupos tales como fenilo, naftilo, quinolilo, piridilo, indoilo y similares en los que el anillo puede estar sustituido por grupos tales como alquilo C1 a C6, amino, nitro, halo, y similares y R6 representa una cadena divalente de polioxialquileno que tiene la fórmula estructural:
-O-(CH2-CH2-O)e-(CH2-CH(R7)-O)f
en la que R7 es un radical orgánico monovalente seleccionado entre hidrocarburos alifáticos C1 a C4, "e" designa un número de grupos etoxi (CH2-CH2-O), "f" designa un númerode grupos etoxi monosustituidos (CH2-CH(R7)-O) en los que la sustitución de un grupo etoxi monosustituido es independiente de la sustitución de cualquier otro grupo etoxi monosustituido en la cadena de polioxialquileno, la suma de"e" y "f" es igual o superior a 0 pero inferior o igual a 10, y en la que la secuencia de grupos etoxi y etoxi monosustituidos dentro de una cadena de polioxialquileno puede ser completamente aleatoria y/o puede haber bloques de grupos etoxi y/o etoxi monosustituidos. Normalmente, el peso molecular promedio dela cadena de polioxialquileno oscila entre 2000 y 10.000.
Los poliepóxidos aromáticos más preferidos son resinas de novolaca epoxi tales como Araldite EPN 1138 y 1139, resinas de novolaca epoxi cresol tales como Araldite ECN 1235, 1273, 1280 y 12 99, resinas de novolaca epoxi fenol tales como Araldite PV 720, resina epoxi 0510, Araldite MY 720 y 721, y Araldite PT 810 todas ellas que están disponibles en Ciba-Geigy. Las resinas Tetrad C y Tetrad X disponibles en Mitsubishi Gas Chemical Co. también son adecuadas para su uso en esta invención.
La preparación de algunas de las resinas epoxi curables autoemulsionantes de la invención tiene lugar a través de un aducto de amina-epoxi, en el que el aducto de amina-epoxi se hace reaccionar posteriormente con una resina epoxi y, opcionalmente, un fenol polihídrico. La estructura del aducto de amina-epoxi depende de las estructuras de la polioxialquilenamina y del poliepóxido aromático usado en la preparación del aducto de amina-epoxi, así como de la relación relativa de los reactivos. Un aducto formado mediante la reacción de 1,0 equivalente de un poliepóxido aromático y entre 0,3 y 0,9 equivalentes reactivos aproximadamente, preferentemente entre 0,6 y 0,8 equivalentes reactivos aproximadamente de una polioxialquilenamina producirá compuestos que tienen la fórmula estructural:
en la que "i" indica un número de unidades de repetición en la que "i" es igual o superior a cero (0) pero inferior o igual a 50 aproximadamente.

Como se ha indicado anteriormente, preferentemente se usa la sal orgánica de cinc, pero en su lugar también se pueden usar otras sales metálicas, tales como magnesio, calcio, y similares.
Preferentemente, el al menos un inhibidor de la corrosión, cuando se proporciona en forma de partículas sólidas y/o líquidas, tienen un tamaño de partícula que es inferior al espesor de la capa de imprimación de un revestimiento y proporciona menos superficie de corrosión. Dichos inhibidores de la corrosión preferentemente son pigmentos anticorrosivos.
Los pigmentos corrosivos de este tipo preferentemente son pigmentos anticorrosivos o pigmentos que contienen plomo, por ejemplo, Ca2PbO4, PbSiO3*3 PbO/SiO2, 2 PbO*PbHPO3 * 0,5 H2O, pigmentos que contienen fosfatos, tales como fosfatos de cinc Zn3(PO4)2* x H2O, polifosfatos, tales como Al(H2PO4)3, fosfatos de cromo tales como CrPO4*3H2O, pigmentos que contienen wolframato o circonato o hierro, tales como 2CaO*Fe2O3, CaO*Fe2O3, Zn(Mg)O*Fe2O3 u otros pigmentos tales como Zn(Ca,Al)-polifosfato/Ba(Zn,Mg,Al)-metaborato o mezclas de Ca/Zn/fosfato/fosfito/borato, molibdato de cerio, wolframato de estroncio o Wayncor® 204, y similares. Además, el pigmento molido puede ser cualquier pigmento, tal como pigmentos amarillos como DCC1202 Diarilide Yellow, que está disponible en el mercado en Dominion Colour Corp.
El inhibidor de la corrosión anódico lleva una carga negativa, y cuando se pone en una celda electroquímica migra hacia el ánodo. El inhibidor de la corrosión de acuerdo con la presente invención preferentemente se selecciona entre óxidos de vanadio, molibdeno, wolframio, y circonio. Naturalmente, también se puede usar como inhibidor dela corrosión anódico combinaciones de estos óxidos.
El inhibidor de la corrosión catódico lleva una carga positiva, y cuando se pone en una celda electroquímica migra hacia el cátodo. El inhibidor de la corrosión catódico preferentemente es un catión de un elemento de las tierras raras, cuyos ejemplos incluyen compuestos de neodimio, cerio y lantano, tales como fosfato de cerio. Naturalmente, como inhibidor de la corrosión catódico también se puede usar combinaciones de estos elementos de las tierras raras.
El inhibidor de la corrosión anódico normalmente se usa en una cantidad dentro del intervalo del 1 aproximadamente al 15 % en peso aproximadamente en base al peso total del contenido en sólidos de la composición deimprimación.
El inhibidor de la corrosión catódico normalmente se usa en una cantidad dentro del intervalo del 1 aproximadamente al 10% en peso aproximadamente en base al peso total del contenido en sólidos de la composición deimprimación.
Cuando el inhibidor de la corrosión anódico y el inhibidor de la corrosión catódico se combinan, con frecuencia el vanadio, molibdeno, circonio y wolframio del inhibidor de la corrosión anódico y los elementos de las tierras raras del inhibidor de la corrosión catódico se pueden disociar de sus respectivos contraiones y se pueden asociar entre sí. Así, dentro del ámbito de la presente invención se contempla la combinación del inhibidor de la corrosión anódico y el inhibidor dela corrosión catódico como compuestoiónico individual, tal como, por ejemplo, molibdato de cerio.
El componente inhibidor de la corrosión preferido además comprende una o más de una sal orgánica de cinc, una sal de alquilamonio o una sal de cicloalquilamonio de un mercapto y/o tiocompuesto o uno de sus derivados sustituidos con alquilo, uno de cuyos ejemplos está disponible en el mercado con el nombre comercial WAYNCOR
204.
