The invention discloses a high-temperature-resistant heat insulation material containing high-boron calcium borate. The material is prepared from the following ingredients in parts by weight: 23 to 27 parts of high-boron calcium borate, 28 to 32 parts of crushed crude pearlite, 25 to 30 parts of silicate, 11 to 14 parts of iron trioxide powder, 15 to 19 parts of sandstone powder, 17 to 18 parts of gypsum powder, 3 to 5 parts of phosphate ester starch and 63 to 69 parts of water. The prepared high-temperature-resistant heat insulation material containing high-boron calcium borate has good high-temperature-resistant and heat insulation effects; the resistance to the heating at 600 DEG C for 25 to 30h can be realized, and no shape change occurs; the heat conduction coefficient of the prepared heat insulation material is 0.022 to 0.027W/(m.K).
