Waterborne acrylic acid waterproof coating and preparation method thereof

The invention relates to the technical field of coatings, in particular to a water-based acrylic acid waterproof coating and a preparation method thereof. The water-based acrylic waterproof coating is prepared from the following raw materials in parts by weight: 15-20 parts of water-based silicone oil acrylic emulsion, 50-65 parts of pure acrylic emulsion, 20-30 parts of filler, 5-9 parts of amino resin, 5-10 parts of a coalescing agent, 3-5 parts of a thickening agent, 0.3-1 part of a defoaming agent and 15-20 parts of deionized water. Wherein the water-based silicone oil acrylic emulsion is obtained by polymerizing a silicone oil monomer, methyl methacrylate, methyl acrylate, hydroxyethyl methylacrylate and styrene emulsion. The water-based acrylic acid waterproof coating provided by the invention has excellent mechanical properties and waterproof performance, and most importantly, the water-based acrylic acid waterproof coating has relatively high adhesive force and relatively high bonding strength, is not
