The invention discloses a silicon aluminum binary hybrid modified rubber powder nanocomposite and a preparation method of the nanocomposite, which is characterized in that: firstly, water, anhydrous alcohol and a precursor containing silicon are added into a vessel, ammonia is also added into the vessel to regulate the pH value in the range of 7.0 to 9.0 and the solution are agitated for 0.5 to 2 hours at 30 to 60 degrees; secondly, rubber powder is added into the vessel and agitated for 2 to 10 hours at 30 to 60 hours; thirdly, a precursor containing aluminum is added into the vessel, hydrochloric acid is added to regulate the pH value to be 7.0, and then the solution are agitated for 2 to 10 hours at 30 to 60 degrees; at last, pumping filtration and drying are carried out till the constant weight of the product is obtained. The silicon aluminum binary hybrid modified rubber powder nanocomposite has the advantages that: the preparation method has s simple technique, mild conditions and easy practice, and the
