The invention relates to the technical field of adsorbents and preparation thereof, in particular to a hydrophobic efficient VOC (volatile organic compound) molecular sieve adsorbent and a preparation method thereof, and provides the following scheme aiming at the problems that an existing adsorbent and a preparation technology thereof still have low regeneration efficiency and the adsorption capacity is obviously reduced after the adsorbent is repeatedly used for multiple times. The preparation method of the hydrophobic high-efficiency VOC molecular sieve adsorbent comprises the following steps: S1, raw material preparation, S2, mixing and stirring, and S3, roasting and desorption, and aims to prepare the hydrophobic high-efficiency VOC molecular sieve adsorbent by taking a ZSM-5 molecular sieve as a base material, adopting a physical mixing mode, adding molecular sieves of other models, regulating the silica-alumina ratio of the molecular sieves and the like. The high-efficiency VOC adsorbent is obtained, the adsorbability to benzene series is improved, the adsorbability to water is reduced, the adsorbent is very suitable for removing industrial organic waste gas, meanwhile, low-temperature desorption is adopted, the regeneration efficiency of the adsorbent is high, and the adsorption is not obviously reduced after the adsorbent is repeatedly used for multiple times.
