摘要（英）：

The invention provides a weather-resistant insulating material for an electric furnace lining and a preparation method of the weather-resistant insulating material, and relates to the technical fieldof weather-resistant insulating materials. The weather-resistant insulating material for the electric furnace lining is prepared from modified attapulgite, silicon carbide, glass beads, hollow acetatefibers, magnesium-zirconium alloy, needle coke, bauxite and nano silicon oxide. The weather-resistant insulating material for the electric furnace lining has excellent electrical insulation performance, heat resistance, flame retardancy and heat and humidity resistance, the preparation method is simple, low in cost, safe and free of pollution, and the service life of an electric furnace can be remarkably prolonged.
