Water-based two-component adhesive

The invention relates to a water-based two-component adhesive and application thereof, in particular to application of covering a rigid base material and a plastic film, a film-coated product containing the adhesive and a method for manufacturing the film-coated product. The aqueous two-component adhesive comprises a component A and a component B, wherein the component A comprises more than 50 wt% and not more than 99 wt% of an aqueous polyurethane dispersion; the component B comprises 1%-16% by weight of water dispersible modified polyisocyanate based on hexamethylene diisocyanate, and the weight percentage is based on 100% by weight of the amount of the adhesive; wherein the aqueous polyurethane dispersion comprises a polyurethane dispersed therein, the polyurethane having a melting enthalpy of 26 to 100 J/g, preferably 30 to 100 J/g, particularly preferably 30 to 60 J/g, at a first temperature rise curve of 20 DEG C to 100 DEG C, measured by DSC according to DIN 65467 (1999). The water-based two-component
