Description

technical field [0001] The invention relates to a recycling process of ceramic fiber cotton, in particular to a composite refractory material based on waste inorganic fiber materials and a preparation method thereof. Background technique [0002] Inorganic fiber materials, such as ceramic fiber cotton, aluminum magnesium silicate insulation cotton, etc., are necessary insulation materials for modern industrial furnaces. They have the advantages of good thermal insulation performance, lightness and durability, and easy construction. However, with the maintenance and renewal of industrial furnaces, a large amount of broken ceramic fibers and magnesium aluminum silicate wastes are produced, which cannot be naturally degraded in nature. At the same time, this waste will drift to Air, soil and water have caused great pollution to the environment. Contents of the invention [0003] The purpose of the present invention is to provide a composite refractory material based on waste...
