High-temperature-resistant organic silicon material

The invention relates to a high-temperature-resistant organic silicon material which is prepared by the following steps of: quickly stirring gamma-glycidoxy-propyltrimethoxy silane and ethanol in a mass ratio of 2: (1-2), and slowly heating for 2-3 hours to obtain a mixed solution; putting the mixed solution, 50-60 parts of an organic silicon copper complex and an organic silicon aluminum complex, 8-20 parts of a silane coupling agent (kh550) and 2-5 parts of an inhibitor into a dispersion machine, and stirring well; and after the reaction is finished and the material is cooled to 70-75 DEG C, adding a platinum catalyst, vacuumizing, stirring and reacting for 30-45 minutes, and then cooling to room temperature to obtain the high-temperature-resistant modified organic silicon material. The novel organic silicon copper complex and organic silicon aluminum complex combination and the catalyst are adopted, so that the prepared material is high in stability and long in storage time and further has good heat resist
