More Information
Summary:The invention belongs to the technical field of ceramic fiber materials, and discloses a preparation method of an alumina fiber-based rigid thermal insulation material. The preparation method of the alumina fiber-based rigid thermal insulation material adopts a fiberboard re-dipping method to prepare the alumina fiber-based rigid thermal insulation material, and specifically comprises the following steps: dipping an alumina fiberboard in a dipping solution with a certain proportion in vacuum, and drying and carrying out heat treatment after dipping to obtain the alumina fiber-based rigid thermal insulation material. The rigid heat insulation material prepared by the invention can effectively solve the problems of short service life, low strength, loose structure and the like of an aluminum oxide fiberboard in a high-temperature use process, and has the characteristics of light weight, high strength, high temperature resistance, erosion resistance, good heat insulation performance, long service life and the li
