Classification: CPC B  C  Y | IPC B  C

Claim 5:
6. The preparation method for a hydrate energy-storage temperature-control material according to claim 1, wherein the electrostatic spraying device in step 3 comprises: a storage bin (1), a coating propulsion device (2), a DC power supply (3), a nozzle (4), a conveyor belt (5) and a collection device (6), wherein the storage bin (1) is configured to internally store a spraying material, i.e. polytetrafluoroethylene suspended ultrafine powder; the coating propulsion device (2) is connected with a spraying device of the storage bin (1) and the nozzle (4) respectively; the nozzle (4) is made of a conductive material, configured to spray the polytetrafluoroethylene suspended ultrafine powder and connected with a negative electrode of the DC power supply (3), and dense negative charges are produced on the nozzle; the conveyor belt (5) of the spraying device is made of a conductive resin-based material and configured to place the hydrate particles (7), the conveyor belt (5) faces the nozzle, so that the suspended particles sprayed out from the nozzle (4) come into contact with the hydrate particles (7) to be sprayed; the conveyor belt (5) is connected with a positive electrode of the DC power supply (3), so that the hydrate particles carry positive charges, and then an electric field required for spraying is formed between the nozzle (4) and the conveyor belt (5).
