Abstract

The invention belongs to the technical field of exterior wall building coatings, particularly relates to a water-resistant and light-corrosion-resistant exterior wall building coating, and solves the problems that an exterior wall building coating in the prior art is poor in weather resistance, insufficient in water resistance and corrosion resistance and short in service life, and the problems of complex raw material selection, multiple components, multiple functions and poor comprehensive performance of the existing water-resistant anticorrosive coatings. The water-resistant and light-corrosion-resistant exterior wall building paint comprises an acrylic emulsion, natural mineral sand, titanium dioxide, an organosilicon waterproofing agent, a preservative, paraffin oil, 4-carboxyl cinnamic acid, an auxiliary agent and water. The raw materials are easy to select, the preparation method is simple, the preparation conditions are mild, the preparation process is green and friendly, and the obtained exterior wall building coating has good flame-retardant, aging-resistant, hydrolysis-resistant, corrosion-resistant, antibacterial, mildew-proof and other effects, is high in hardness, good in wear resistance and excellent in comprehensive performance, can be widely applied to decoration and protection of building exterior walls and is long in service life.

Description

technical field [0001] The invention relates to the technical field of exterior wall architectural coatings, in particular to a water-resistant light anti-corrosion exterior wall architectural coating. Background technique [0002] Architectural coatings refer to materials that are coated on the surface of building objects and can be well bonded to the base material and form a complete and tough protective film. The role of coatings can be summarized into three aspects: protection, decoration, and special functions. The general composition of coatings: including film-forming substances, pigments and fillers, solvents, and additives. The application environment of architectural coatings, especially exterior wall architectural coatings, is relatively harsh. Ultraviolet rays, heat energy, microorganisms, water, and air pollutants all have an impact on the properties of polymers in coatings, and among them, ultraviolet aging, rain erosion and corrosion are destructive maximum....
