The invention discloses a quick-cooling sticker which comprises a heat preservation layer (1), a sealing layer (2), water (3), a non-setting adhesive (4), a protecting layer (5), nitrate (6) and the like. The quick-cooling sticker works based on the principle that the nitrate is dissolved in the water and can absorb heat from the outer world. When the quick-cooling sticker is in use, heat of an object to be cooled can be taken away only by mixing the water and the nitrate in the sealing layer, uncovering the protecting layer and sticking the non-setting adhesive to the surface of the object to be cooled.
