The invention belongs to the field of high-temperature alloy materials, and particularly discloses a high-strength platinum-based high-temperature alloy material and a preparation method and application thereof.The high-strength platinum-based high-temperature alloy material comprises a platinum matrix, an oxide skeleton and a pure platinum layer, and the pure platinum layer covers the lower portion of a material formed by compounding the platinum matrix and the oxide skeleton. An oxide dispersion strengthening phase is the basis of platinum-based alloy reinforcement, a powder metallurgy liquid phase sintering technology is adopted, a composite material of a platinum matrix and a high-temperature-resistant oxide framework is manufactured, oxide powder is directly adopted as a dispersion phase, the defects of an internal oxidation process are overcome, the mass fraction of oxide in the material reaches 22% to the maximum, and the material is high in mechanical strength and high in mechanical strength.
