The invention discloses a PVC material composite water-based adhesive. The composite water-based adhesive is prepared from the following raw materials in parts by weight: 35-50 parts of polyurethane modified acrylic prepolymer, 15-20 parts of petroleum resin, 9-12 parts of rosin resin, 4-6 parts of a plasticizer, 6.5-8.5 parts of organosiloxane monomer, 1-5 parts of an initiator and 5-8 parts of an accelerant. The PVC material composite water-based adhesive prepared by the invention has good bonding strength, good leveling property, smooth surface after coating and no agglomeration, caking orwatermarks, and does not yellow after being placed for 30 days after being used.
