The invention relates to a high-temperature-resistant composite material missile wing and a preparation method thereof, wherein the high-temperature-resistant composite material missile wing mainly comprises a structural layer, a heat insulation layer and an anti-ablation layer, and the heat insulation layer exists on the surface except a front edge, a wingtip and a rear edge; and only the front edge, the wingtip and the rear edge are provided with anti-ablation layers. The preparation method comprises the steps: preparing a prepreg from phthalonitrile resin, a carbon fiber fabric, a glass fiber fabric, a high-silica fabric and the like by using a wet prepreg machine, preparing a premix from phthalonitrile resin and high-silica chopped fibers by using a stirring kettle, manually paving a heat-insulating layer on the lower surface into a female die, paving a structural layer, and then paving a heat-insulating layer to the upper surface; and finally, manually spreading an anti-ablation layer, closing a male mol
