High-temperature-resistant inorganic label paper

The invention relates to high-temperature-resistant inorganic label paper. An inorganic fire-resistant surface material layer of the high-temperature-resistant inorganic label paper comprises hydroxyapatite ultra-long nanometer lines and inorganic fiber. Compared with a conventional high-temperature-resistant label, the novel high-temperature-resistant inorganic label paper does not contain any organic matter, has higher temperature-resistant performance, can be used for a long time in high-temperature environment, and has incombustibility and good heat insulation performance.
