Zusammenfassung:	The invention provides a wear-resistant wheat straw composite board and a preparation method thereof, and belongs to the technical field of biomass utilization. The preparation method comprises the following steps: by taking wheat straw as a raw material, respectively carrying out acylation modification on the wheat straw, introducing an active group acryloyl group to the wheat straw, then carrying out esterification reaction with chloroacetic acid to further introduce an active group carboxymethyl group to the wheat straw, compounding the modified wheat straw with modified attapulgite, and carrying out a hot-pressing process under the action of an initiator to prepare the wear-resistant wheat straw composite board. Due to the fact that the modified attapulgite forms a thin self-lubricating two-dimensional structure in the friction process, spreading on a friction interface of the composite board is easier, loads are evenly transmitted, and a uniform and compact lubricating film is formed on the surface of a
