Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special modified acrylic resin coating for building exterior walls. Background technique [0002] Exterior wall coatings are used to paint the exterior walls of buildings. The application environment is relatively harsh. Ultraviolet rays, heat energy, microorganisms, water, and air pollutants can all cause the aging of polymers in the coatings. Therefore, coatings for building exterior walls UV aging resistance, water resistance and self-cleaning properties are required. The strength, aging resistance and water resistance of the existing coatings for building exterior walls are not very satisfactory, and need to be improved to meet the requirements of a rapidly developing society. Contents of the invention [0003] The invention provides a special modified acrylic resin coating for building exterior walls, which has high strength, good aging resistance and water resistance,...
