NOVELTY - Aqueous double-component graphene varnish comprises components A comprising 70-85 wt.% hydroxyacrylic acid dispersion, 10-25 wt.% graphene slurry, 0.2-2 wt.% multifunctional amine auxiliary agent, 0.3-2 wt.% wetting agent, 0.3-2 wt.% leveling agent and 0.3-2 wt.% thickener, and component B comprising 60-80 wt.% polydiisocyanate, 0-20 wt.% polyisophorone diisocyanate and 10-30 wt.% propylene glycol diacetate. USE - The varnish is useful for wooden ware (claimed). ADVANTAGE - The varnish: has high fullness, high permeability, high gloss and high surface resistance; solves the problem that the existing water-based wood coating has poor fullness, poor surface resistance and low gloss compared with the solvent-based wood coating; improves the drying speed of the aqueous wood coating; and improves the coating efficiency of the wood coating. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing the aqueous double-component graphene varnish, comprising (i) preparing component A by (ia) uniformly mixing hydroxyacrylic acid dispersion and aqueous substrate wetting agent, (ib) mixing and stirring the mixture, simultaneously adding multifunctional amine adjuvant, and adjusting the pH of the mixture to 8-9, (ic)uniformly stirring the mixture, slowly adding graphene slurry, and continuously stirring and mixing, (id) continuously adding leveling agent in the mixture, and continuously stirring and mixing, and (ie) continuously adding thickener to adjust the viscosity, uniformly stirring, and filtering, and (ii) preparing component B by mixing and dispersing propylene glycol diacetate and polydiisocyanate; and (2) use method of the aqueous double-component graphene varnish, comprising mixing component A and component B in a mass ratio of 5:1-2, and uniformly stirring.
