This invention has advantages such as high magnetization intensity, long saturation period, simple operation, and convenient maintenance.

The invention discloses a carbon fiber reinforced gypsum board with a broadband electromagnetic shielding function and a preparation method of the carbon fiber reinforced gypsum board. The gypsum board is prepared from the following components in percentage by mass: 74.0 to 89.0 weight percent of gypsum powder, 10.0 to 25.0 weight percent of iron-nickel oxide modified short carbon fibers, 0.3 to 0.5 weight percent of a water reducing agent and 0.3 to 0.5 weight percent of a retarder. The carbon fibers modified by the iron-nickel oxide nanoparticles are adopted to reinforce the gypsum board, a conductive network is constructed in a matrix, and magnetic eddy current loss and magnetic hysteresis loss are enhanced, so that the gypsum board can achieve high-efficiency wide-frequency-band electromagnetic shielding effectiveness while obtaining excellent mechanical properties. The gypsum board disclosed by the invention can be widely applied to internal and external walls of large-scale electronic and electrical equipment, supercomputers and electronic security facilities, and a security room with a good electromagnetic security effect can be quickly assembled and built.
