Abstract

The invention belongs to the field of coatings, and discloses an antifouling exterior wall glaze. The antifouling exterior wall glaze comprises organic silicon resin, inorganic nanoparticles, fluorine-containing resin and a drier, wherein the mass ratio of the organic silicon resin to the fluorine-containing resin to the drier is 1:(0.1-0.2):(0.6-0.9). The antifouling exterior wall glaze providedby the invention has good water resistance, mildew resistance, temperature change resistance and weather resistance. The exterior wall glaze has an excellent antifouling function, and the main reasonsare that emulsion particles of a nano core-shell composite emulsion are extremely small in particle size, arrangement is regular after film drying, film forming is compact and hardness is relativelyhigh, so that dirt such as dust and greasy dirt are unlikely to permeate into a coating film, dirt on the surface can be washed away by rainwater, and therefore, the coating is kept clean.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an antifouling exterior wall glaze and a preparation method thereof. Background technique [0002] In the building decoration industry, the existing general interior wall coatings have disadvantages such as poor hiding power, easy powder removal, and inability to scrub. With the development of society, these ordinary interior wall coatings can no longer meet people's requirements for building house decoration. Therefore, people hope that there will be new types of building interior and exterior wall coatings. [0003] Exterior wall paint is used to paint the exterior walls of buildings, so the most important indicator is anti-ultraviolet radiation, which requires long-term exposure without discoloration. Some exterior wall coatings also require water resistance and self-cleaning properties. The paint film should be hard and smooth, and the dirt will fall off as soon as it is washed. Ho...
