Refractory heat insulation material and preparation method thereof
The invention relates to a refractory heat insulation material and a preparation method thereof. According to raw materials of the refractory heat insulation material, hole-closed perlite floating beads serve as heat insulation aggregate, bauxite, kaolin and pyrophyllite serve as refractory aggregate, potassium feldspar serves as a sintering agent and sodium-based bentonite serves as a forming agent. The preparation method includes the steps of stirring the raw materials, forming a blank through a mould, air-drying the blank, performing demoulding after low-temperature drying, and performing high-temperature ceramization and sintering forming on the blank. By fully utilizing the physicochemical characteristics of all the components, the overall performance of the refractory heat insulation material is optimized, and the prepared refractory heat insulation material has the advantages of being high in refractoriness and strength, small in bulk density, low in heat conductivity coefficient, good in heat insulation effect, environmentally friendly and the like and can be applied to heat insulation of heating furnaces or heat equipment in the machinery industry, the metallurgy industry, the chemical industry and the like and slow down heat energy diffusion to save energy.
