Abstract
Un procedimiento para cerrar herméticamente un dispositivo eléctrico aislado, que comprende las etapas de introducir en dicho dispositivo una composición que comprende aceite mineral, un precursor de poliuretano y agentes de copulación, a) siendo preparado dicho poliuretano haciendo reaccionar: i) un compuesto de poliisocianato que contiene al menos aproximadamente 0,25 equivalentes de un poliisocianato alifático de cadena larga, y ii) un poliol seleccionado entre el grupo que consta de aceite de ricino, polieter- polioles, homopolímeros de dienos que poseen grupos hidroxilo, copolimeros de dienos que poseen grupos hidroxilo, y combinaciones de los mismos, y b) estando caracterizado dicho agente de copulación por i) ser miscible en todas proporciones con dicho aceite mineral, ii) tener un parámetro de solubilidad total comprendido entre aproximadamente 7,0 y aproximadamente 9,5, iii) tener un número de índice de unión de hidrógeno comprendido entre aproximadamente 6,0 y aproximadamente 12,00 y iv) ser substancialmente no reactivo con dicho prepolímero de poliisocianato y dicho poliol; hacer reaccionar dicho poliol con dicho prepolímero de poliisocianato en presencia de dicho aceite mineral y dicho agente de copulación para obtener un poliuretano extendido con aceite mineral, reticulado, curado, compatible con grasa, que no sufre segregación, y que esta caracterizado por la presencia de un resto polidiénico en la estructura de poliuretano, y que comprende entre aproximadamente 8 y aproximadamente 45 partes de poliuretano, entre aproximadamente 20 y aproximadamente 10 y aproximadamente 47 partes de agentes de copulación, expresadas todas las partes sobre la base de peso.
