A preparation method of a ceramic plugboard with silicon carbide whiskers in theta-angle distribution is characterized in that silicon carbide whisker powder is distributed on a retainer plate through a whisker theta-angle distribution device according to the theta angle to form a silicon carbide whisker powder layer with a certain thickness, then silicon carbide micro powder, metal silicon powder and carbon micro powder are prepared into slurry with a certain viscosity, and the slurry is put into a mold for molding, so that the ceramic plugboard with the silicon carbide whiskers in theta-angle distribution is obtained. And uniformly spraying the slurry on a silicon carbide whisker powder layer, pressing into a plate after uniformly wetting, shaping into an arc shape to prepare a ceramic insertion plate blank with the silicon carbide whiskers distributed at the theta angle, and burying, sintering and siliconizing at a certain temperature to prepare the ceramic insertion plate with the silicon carbide whiskers distributed at the theta angle. According to the prepared ceramic plugboard, the silicon carbide whiskers are arranged in a plane according to the theta angle, the bending strength of the silicon carbide ceramic plugboard is remarkably improved, longitudinal kinetic energy can be dispersed to the transverse direction to the maximum extent, and the breakdown resistance of the silicon carbide whisker ceramic plugboard is improved.
