The invention provides an epoxy modified silicon-contained waterborne acrylic resin which is prepared by the following steps of: carrying out addition reaction on epoxy resin and acrylic acid to produce epoxy monoacrylate resin; and then carrying out free-base co-polymerization by taking the epoxy monoacrylate resin as a monomer and matching an acrylic acid monomer and an amio silicone monomer toobtain a product. The method overcomes the defects of overlarge viscosity, inconvenient operation, and the like during reaction caused by the fact that the epoxy resin is directly inoculated with theacrylic acid in the past; the resin is matched with soluble amino resin to form a film forming matter, then the resin is matched with relevant pigment and assistants to obtain a waterborne coating which can form a film after solidified at 70-80 DEG C for 20 min when used for the surface of glass; and epoxy amino can obtain excellent adhesive force through solidification and has excellent acid-alkali resistance. The amio silicone monomer has the performance of being baked and solidified at low temperature and achieves fine flexibility, and still has higher hardness and better adhesive force after being water-tolerant, thereby overcoming the defect of being scratched by hard matters in damp and hot environments.
