A method of preparing a water-based adhesive with high binding property based on polymer composites is provided, belonging to the technical field of preparation of water-based adhesives. The present invention specifically relates to a method of forming a polymer composite by blending solutions and then preparing the water-based adhesive with high binding property. The preparation method of the present invention is simple, obtaining the composite polymer hydrogel merely by blending solutions, with the dense water-based adhesive produced by centrifugation. This water-based adhesive is formed based on multiple weak interactions among the polymers, with the forming process simple and efficient and involving no sophisticated instruments and equipment; no organic solvent needs to be added in the preparation process, odor free, non-toxic and environment-protective, and common raw materials are used that are inexpensive. This water-based adhesive can be used for bonding glass, metal, wood, plastic and other various materials, and has high binding strength, allowing the materials (except plastic) to be bonded directly without surface pretreatment or modification. It is expected that the water-based adhesive prepared by the present invention will be applied in a wide range of fields.
