The method of dispersing and blending with high-speed disperser was used to prepare acrylic waterprof coating modified with dfferent fluorocarbon content,and the influence of fluorocarbon emulsion on the adhesive strength,tensile strength,breaking elongation,impermeability and other properties of acrylic waterproof coating.The result manifest that with the increase of the fluorocarbon emulsion content,the breaking elongation of the coating reaches 676.29%,and the tensile strength of the coating gradually increases,with the maximum value reaching 0.802 MPa,indicating that the fluouocarbon emulsion can cenhnce the strength of the coating.
