The invention relates to the technical field of composite floor preparation, in particular to a light high-strength composite floor and a preparation method thereof. The preparation method of the light high-strength composite floor comprises the following steps: step 1, uniformly mixing wood chips, fibers and silicon dioxide aerosol to obtain a solid mixture; uniformly mixing the polyurethane adhesive A with epoxy resin and a curing agent to obtain a mixed solution; adding polyether polyurethane into the mixed solution, and uniformly mixing to obtain mixed glue A; uniformly mixing the mixed glue A with the solid mixture to obtain a glue A mixture; uniformly mixing the polyurethane adhesive B and the adhesive A mixture to obtain a pressed mixture; and 2, the pressed mixture is subjected to forming and heat treatment, and the light high-strength composite floor is obtained. The method is simple, raw materials are easy to obtain, and large-scale industrial preparation is easy; the composite floor prepared by the method has the properties of light weight and high strength, and can be used as a railway flatcar floor.
