The invention discloses a single-component water-based adhesive for an evaporative cooling wet curtain and a preparation method thereof. The method comprises the following steps of: firstly preparing kettle bottom liquid and adding into a polymerization reaction kettle; then respectively preparing nuclear layer pre-emulsion, transition layer pre-emulsion and shell layer pre-emulsion; removing possibly-caused free formaldehyde through carrying out nuclear layer-transition layer-shell layer gradient emulsion polymerization, by adopting an environmentally-friendly and highly-efficient reactive emulsifier and through replacing hydroxymethyl acrylamide with a novel self-crosslinking monomer and replacing sodium formaldehyde sulphoxylate with a macromolecule polymerization type reducing agent; and introducing carbamido or nitrogen heterocycle into an acrylate structure to provide a higher intermolecular hydrogen bond and an intermolecular acting force and improve the wet adhesive force and the scrub resistance of an adhesive layer. The invention has the beneficial effects that the adhesive force and the water resistance of the adhesive layer are ensured through ion crosslinking and in cooperation with diacetone acrylamide / adipic dihydrazide crosslinking; and by adopting an adjusting agent with the super-strong defoaming and wetting functions, the adhesive is ensured to satisfy higher coating rate in the gluing process and not to generate tiny bubble residues.
