Abstract

The invention discloses a high-temperature-resistant thermal-insulation material prepared with industrial tailings, which includes following components, by weight: 30-49% of the industrial tailings, 5-8% of perlite, 10-15% of asbestos wool, 10-15% of bentonite, 15-22% of a solidifying system, 1-5% of a penetrant, and 10-20% of water. The thermal-insulation material is low in thermal conductivity coefficient, is not liable to crack and fall off, and is good in sealing performance. 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 a thermal insulation material, 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 metals can improve high-temperature strength, 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 is high, which is not conducive to low-cost and industrial development, and it is inevitable to seek other preparation raw materials. [0003] With economic development, a large number of mineral resources have been developed and utilized, and ore has become increasingly scarce. As a secondary resource, tailings ...
