Abstract

Composite nanometer weather-proof waterproof coating and a preparing method thereof are disclosed. The coating comprises nanometer titanium nitride, nanometer magnesium carbonate, alkyd resin, polyvinylidene chloride resin, chlorosulfonated polyethylene, benzyl butyl phthalate, tung oil, n-butanol and amyl acetate. The preparing method includes (1) weighing the nanometer titanium nitride and nanometer magnesium carbonate, and fully mixing in a high-speed mixer; (2) adding the tung oil, the n-butanol and the amyl acetate into a stirring tank, and stirring in a sealed manner until the mixture is fully mixed; (3) adding the alkyd resin, the polyvinylidene chloride resin, the chlorosulfonated polyethylene and the benzyl butyl phthalate into the stirring tank, and mechanically stirring; and (4) adding the powder fully mixed in the step (1) into the stirring tank, and fully stirring to obtain the coating.

Description

technical field [0001] The invention belongs to the field of decorative coatings, and relates to a waterproof coating and a preparation method thereof, in particular to a composite nanometer weather-resistant waterproof coating and a preparation method thereof. Background technique [0002] Exterior wall paint is used to paint the facade of buildings, so the most important indicator is anti-ultraviolet radiation, which requires long-term exposure without discoloration. Exterior wall coatings also require water resistance and self-cleaning properties. Exterior wall paint is exposed to the outdoors for a long time, and is exposed to wind, rain and sun. After a period of time, the appearance of the finish will be powdered, discolored, faded, and lose light. There are many types of exterior wall coatings, which can be divided into strong acid and alkali resistant exterior wall coatings, silicone self-cleaning and water-resistant exterior wall coatings, tempered waterproof putty...
