The invention discloses a multi-layer composite impact-resistant plate based on a high-strength polyethylene microporous membrane and a preparation method of the composite plate. The composite plate is prepared by gluing a plurality of coating membranes, an adhesive layer is arranged between two coating membranes, each coating membrane comprises a base material and a coating layer, and the number of the coating membranes is 700-1200. High-strength polyethylene microporous membranes are selected as a base material, the surfaces of the high-strength polyethylene microporous membranes are coated with aluminum oxide ceramic particles to prepare the coating membranes, and then the multiple layers of coating membranes are bonded through an adhesive to prepare the composite plate. The base material has high strength, a ceramic powder prepared from alumina has excellent wear resistance and high hardness, and micropores are formed in the base material in the preparation process, so that the prepared composite plate ca
