High temperature resistant material and preparation method thereof

Abstract

The invention discloses a high temperature resistant material and a preparation method thereof, the material includes the following components by weight: 78-80wt% of Al3O3, 15-19.5wt% of MgO and 7.2-11.5wt% of CaO. The high temperature resistant material is prepared from a raw material of dolomite mineral with wide distribution and low price, and can effectively use the MgO and the CaO components in the dolomite, and the obtained high temperature material has the advantages of light weight, high anti alkali corrosion performance and low cost.

Description

technical field [0001] The application belongs to the technical field of materials, and in particular relates to a high temperature resistant material and a preparation method thereof. Background technique [0002] The use of high temperature resistant materials is one of the important factors for energy saving and consumption reduction of industrial furnaces. The heat storage loss of industrial kiln masonry and the heat loss of the furnace surface generally account for about 24-45% of fuel consumption. [0003] Existing high-temperature-resistant materials generally use mullite and alumina heat-insulating bricks, etc., but such high-temperature-resistant materials usually have technical defects of poor alkali corrosion resistance and high cost. Contents of the invention [0004] The object of the present invention is to provide a high temperature resistant material and its preparation method to overcome the deficiencies in the prior art. [0005] To achieve the above ob...
