The invention relates to the field of building materials and particularly relates to a rice husk composite wood-imitated sheet. The sheet comprises, by weight, 20-23 parts of rice husks dried and crushed into powder having a particle diameter of 120-160 meshes, 20-25 parts of bentonite crushed into powder having a particle diameter of 240-270 meshes, 0.7-1.2 parts of an AC foaming agent, 1.5-1.8 parts of a foaming adjuster, 145-151 parts of PVC resin, 4-7 parts of a stabilizer, 0.4-0.6 part of N,N'-ethylenebis(stearamide), 0.2-0.5 part of glycerol monostearate, 0.3-0.6 part of a coupling agent and 5-7 parts of chlorinated polyethylene. The rice husks are adopted as a main raw material of the sheet, avoid destroy caused by sawdust to the environment, and do not contain formaldehyde or other harmful compounds. The prepared sheet does not have cracks, bubbles, swells, mark wrinkles, tenons or corner defects, and has high surface gluing strength.
