Description
Technical Field
The invention relates to the technical field of exterior wall building coatings, in particular to a water-resistant light-weight anticorrosive exterior wall building coating.
Background
Architectural coatings are materials which when applied to the surface of an architectural object adhere well to a substrate material and form a complete, tough protective film. The effect of the coating can be summarized in three aspects: protection, decoration and special functions. General composition of the coating: comprises film forming matter, pigment and filler, solvent and auxiliary agent. The application environment of the building coating, especially the exterior wall building coating, is relatively severe, ultraviolet rays, heat energy, microorganisms, pollutants in water and air and the like all affect the performance of polymers in the coating, and the destructiveness of ultraviolet rays for aging, rain erosion corrosion and the like is the greatest. Therefore, the development of the exterior wall building coating with good weather resistance, water resistance and corrosion resistance has profound significance.
The Chinese invention patent CN104327657B discloses a special energy-saving heat-insulating water-resistant anticorrosive paint for building exterior walls, and specifically discloses the following contents: the coating comprises the following raw materials in parts by weight: 100 parts of fluorine-silicon modified acrylate emulsion, 5-9 parts of epoxy resin, 10-15 parts of waterborne polyurethane, 10-26 parts of foaming polyurethane, 5-9 parts of vitrified micro bubbles, 15-30 parts of mineral wool, 8-15 parts of rutile titanium dioxide, 5-15 parts of talcum powder, 3-6 parts of silane coupling agent, 3-9 parts of pH regulator and 5-10 parts of infrared radiation composite powder, 10-20 parts of hollow silica microspheres, 5-10 parts of composite iron titanium powder, 10-15 parts of modified zinc phosphate, 3-7 parts of zinc oxide, 0.2-0.6 part of 2-amino-2-methyl-1-propanol, 0.2-2.5 parts of defoaming agent, 10-18 parts of film-forming additive, 5-8 parts of thickening agent, 1-3 parts of wetting agent and 50-70 parts of water. The raw materials of the patent are selected and used in a complex way, the components are more, and the produced exterior wall building coating has more functions but not strong comprehensive performance. Based on the statement, the invention provides a water-resistant light-weight anticorrosive exterior wall building coating.
