The invention discloses a fluidized crosslinking method for microcapsules, and relates to the microcapsules and provides the fluidized crosslinking method for the microcapsules, which can remarkably improve the crosslinking efficiency and the quality of a product. The fluidized crosslinking method comprises the following steps: preheating a fluidized bed; adding formed to-be-crosslinked microcapsules into the preheated fluidized bed; adjusting the temperature and the humidity of gas fluid introduced into the fluidized bed, and enabling the microcapsules to enter a quick crosslinking reaction stage; after crosslinking is completed, cooling the microcapsules to normal temperature, thus obtaining water-repellent microcapsules. The water of the microcapsules can be controlled at water content when the speed of a crosslinking reaction is highest by controlling the temperature of the crosslinking reaction and the humidity of the gas fluid, so that the aim of quickly crosslinking is achieved. Compared with a traditional wall-dividing heating and crosslinking process, the fluidized crosslinking process has the advantages of uniformity in heating, high crosslinking speed, high microencapsulation yield, low surface oil, long shelf life of a product and the like. The crosslinking efficiency and the quality of the product can be remarkably improved by researching influence factors of the crosslinking process and controlling the water of the microcapsules in the reaction process.
