The invention also discloses a preparation method of the high-temperature-resistant thermal-insulation material with the industrial tailings, which comprises steps of: weighing the raw materials, mixing the raw materials and sealing and storing the mixed raw materials. The preparation method is simple and convenient to carry out, is low in cost and is suitable for industrial production.

Description

technical field [0001] The invention relates to thermal insulation materials, in particular to a high-temperature-resistant thermal insulation material made from industrial tailings and a preparation method thereof. Background technique [0002] In the prior art, adding a small amount of rare earth metal can increase the high-temperature strength, improve metal strength, elongation, heat resistance and oxidation resistance. Based on the above characteristics of rare earths, rare earths are used to prepare heat insulation materials. However, rare earth metals are rarely enriched to the extent that they can be mined, and the degree of utilization is not high, and the cost of obtaining them is high, which is not conducive to low-cost and industrial development. It is inevitable to seek other raw materials for preparation. [0003] With the development of the economy, a large number of mineral resources have been developed and utilized, and the ore has become increasingly scarc...
