Stereoscopic drawing board

The invention relates to a stereoscopic drawing board, which consists of hexahedron and is characterized in that the drawing board is a columnar body and is formed by mixing, pressure casting and heating fly ash and 1 to 10 percent of polyvinyl chloride (PVC) or polythene (PE) film tapes; the front surface consists of a cambered surface or an inclined surface and the cambered surface; the width of the cambered surface is 8 to 18 times of the depth of the cambered surface; the outer surface of the drawing board is provided with a picture and text layer; the two-dimensional picture and text layer and the cambered surface are combined to form the stereoscopic characteristic of the drawing board; and a drawing frame is not used, and picture lines are more fluent. The stereoscopic drawing board has the following advantages that: 1, the manufacturing cost is low and the construction period is short; 2, the stereoscopic impression is strong, and picture materials are abundant; 3, the materials can be waste material, and be energy-saving and environment-friendly; 4, the drawing frame is not arranged, and the application range is wide; and 5, the products have a plurality of specifications and can be industrially produced in batch.
