Abstract

The invention discloses a high-elasticity external wall coating with enhanced anti-corrosive performance of composite epoxy resin emulsion. The high-elasticity external wall coating is prepared from, by weight, 20-22 parts of methyl methacrylate, 29-31 parts of butyl acrylate, 8.5-9.5 parts of hexafluorobutyl acrylate, 4-5 parts of vinyl triethoxy silane, 0.1-0.12 part of ammonium persulfate, 2-3 parts of OP-1, proper amount of deionized water, proper amount of amino water, 1.5-2 parts of n-dodecanol ester, 8-10 parts of superfine kaoline, 3-4 parts of polyether polyol, 2-3 parts of epoxy resin, 7-8 parts of epoxy resin emulsion, and 1-2 parts of boron trifluoride diethyl etherate. The high-elasticity coating has water-based formula and is free from toxic and pollution, high in ductility, excellent in weather fastness, convenient to construct; the coating is especially suitable for the waterproof use of the external wall of the building engineering; the coating film is smooth and beautiful.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-elastic exterior wall coating with enhanced anticorrosion performance of a composite epoxy resin emulsion. Background technique [0002] At present, an important development direction of building exterior wall coatings is energy-saving and thermal insulation. The performance of the emulsion used for the facing layer has a direct impact on the water resistance, stain resistance, durability and temperature resistance of the external wall thermal insulation system, and the wall Body cracks will cause rainwater and carbon dioxide gas intrusion, cause steel bar corrosion, and accelerate wall carbonization speed. Building wall cracks have become one of the common problems that affect the quality of construction projects. Due to the good extensibility of the coating, elastic architectural coatings can resist and cover the cracks in the base layer to a certain extent, and are fav...
