The invention discloses a method for preparing a geranyl acetone sustained-release material. The method comprises the following steps of 1 surface activation, wherein an Hbeta molecular sieve is put into a tubular furnace, heating is conducted to reach a preset temperature, steam is introduced for a period of time for surface activation; 2, hydrogen reduction, wherein gas introduced into the tubular furnace is replaced with hydrogen, after gas is introduced for a period of time, gas introduced into the tubular furnace is replaced with nitrogen, and cooling is conducted to reach the room temperature; 3, impurity cleaning, wherein after an Hbeta molecular sieve mixture subjected to hydrogen reduction treatment is soaked with diluted hydrochloric acid, cleaning is conducted on distilled water, drying is conducted, and a required sample can be obtained. The method has the advantages that the prepared modified Hbeta molecular sieve can effectively weaken the adsorption capacity of the Hbeta molecular sieve to geranyl acetone while the adsorption quantity of the Hbeta molecular sieve to the geranyl acetone keeps essentially constant, and then the sustained-release performance of the Hbeta molecular sieve to the geranyl acetone can be effectively improved.
