The invention relates to paint composite and a preparation method thereof, in particular to fingerprint-resisting paint for manufacturing galvanized fingerprint-resisting plates and a preparation method thereof. The water base fingerprint-resisting paint which is used for the galvanized plates is characterized by being prepared from raw materials comprising waterborne resin, inorganic salt, silicasol, auxiliary agent A, auxiliary agent B and water, wherein the weight percentage of each raw material is as follows: the waterborne resin accounts for 15 to 30 percent, the inorganic salt accounts for 0.3 to 1.0 percent, the silicasol accounts for 5 to 10 percent, the auxiliary agent A accounts for 10 to 20 percent, the auxiliary agent B accounts for 4 to 10 percent and the water accounts for 50 to 65.7 percent, and the sum of weight percentage of the raw materials is 100 percent. The invention has the advantages of environmental protection and simple process. The paint composite can be sprayed on the surface of a hot galvanized steel plate, an electrogalvanized steel plate, an aluminum plated zinc plate or a cold-roll steel plate by the modes of dip-coating, spraying, roller painting, and the like, and the curing time is short and only lasts for 20 seconds to 1 minute; after the steel plates are sprayed, the requirements of the steel plates on corrosion resistance, alkali resistance, high temperature resistance, electrical conductivity, paintability, and the like can be met, and the fingerprint resistance of the steel plates can be greatly improved.
