Abstract

The invention belongs to the technical field of building paints, and provides a nano external wall paint and a preparation method thereof. The nano external wall paint comprises: a hollow glass bead composition, hydroxyethyl cellulose, quartz sand (20-40 meshes), rutile type titanium dioxide, a filling material, a fire retardant, a crosslinking agent, and an antifoaming agent. The components mentioned above are blended according to a certain weight ratio, primarily stirred, sand-grinded, blended, filtered and sieved to prepare the paint. After a wall is painted by the paint, the wall has weatherability and a waterproof function. At the same time, the paint has a good fire retardant performance and can enhance the fireproof performance of the wall.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and in particular relates to a nanometer exterior wall coating and a preparation method. Background technique [0002] As an important product category in home decoration materials, coatings for building wall decoration directly reflect and affect the effect and function of home decoration. According to the different functions and characteristics of coatings, multifunctional nano-exterior wall coatings with self-cleaning, anti-fouling, scrub resistance, weather resistance and long-lasting quality are very popular in the market and are gradually becoming an important leader in the coatings industry. Product Series. Among them, the nano-wall coating using nano-silica hydrophobic antifouling agent has been recognized as one of the wall coatings with excellent water resistance and weather resistance. However, the flame retardant performance of this kind of coating is not good. [00...
