Abstract

La presente invención se refiere a tecnologías químicas, específicamente a nanopartículas de hidróxido de magnesio retardante de llama, y un procedimiento para la preparación de las mismas; las presentes nanopartículas de hidróxido de magnesio retardante de llama, incluyendo nanopartícula con superficie procesada, tienen una estructura tipo placa hexagonal con un área de superficie específica de hasta 20 m2/g, un diámetro promedio de las partículas secundarias de hasta 2 µm, un diámetro deI 10 % de las partículas secundarias de hasta 0.8 µm, un diámetro del 90 % de las partículas secundarias de 5 µm, con un tamaño longitudinal de las partículas primarias de 150 a 900 nm, y un espesor de 15 a 150 nm; el presente procedimiento para la preparación de nanopartículas de hidróxido de magnesio retardante de llama, incluyendo nanopartículas de superficie procesada, consiste en dos pasos, en donde el primer paso consiste en la interacción de una solución acuosa de cloruro de magnesio con un componente alcalino a una temperatura de hasta 100 °C y presión atmosférica, con una relación molar de iones OH- : Mg++ en la escala de 1.9÷2.1 : 1, y el segundo paso consiste en la recristalización hidrotérmica de las partículas de hidróxido de magnesio a una temperatura de 120 - 220 °C, una presión de 0.18 a 2.3 MPa y una duración de 2 a 24 horas, en donde, durante la recristalización hidrotérmica, para evitar un crecimiento adicional de las partículas primarias y el engrosamiento por agregación de las partículas secundarias, la masa de reacción es sometida a impactos hidráulicos periódicos con vapor supercaliente a una temperatura de 160 - 240 °C y una presión de 0.6 a 3.3 MPa; las nanopaitículas de hidróxido de magnesio retardante de llama, obtenidas de acuerdo con el presente procedimiento, tienen tamaños controlables de las partículas primarias y secundarias y un área de superficie específica, lo que permite utilizarlas en un retardante de LLAMA no tóxico, supresor de humo, sin una reducción en las propiedades mecánicas y la efectividad tecnológica en matrices poliméricas orgánicas, comprendiendo polietileno, polipropileno, copolímero de etileno propileno, copolímero de etileno acrilato, poliestireno, polímero a base de etileno-co-vinilacetato, poliamida, poliimida, policarbonato, tereftalato de polietileno, tereftalato de polibutileno, plástico ABS.
