The invention belongs to the field of polyurethane synthesis and concretely relates to a self-skinning compound material for a heat-resistant polyurethane foaming tyre and a preparation method thereof. The self-skinning compound material is prepared from a component A and a component B according to a mass ratio of 100: 80-90. The component A comprises polyether polyol, polymer polyol, a cross-linking agent and/or chain extender, a pore forming agent, a foam stabilizer, a catalyst and a foaming agent. The component B comprises polyester polyol and isocyanate. The self-skinning compound material can improve polyurethane heat resistance. The prepared tyre has excellent performances and can be used for a long time under conditions of loading and a high rate. The invention also provides a preparation method of the self-skinning compound material. The preparation method has reasonable processes.
