Abstract

The invention provides an exterior wall protecting coating and a preparation method thereof. The exterior wall protecting coating comprises the following components in part by mass: 11.5-24 parts of silicone acrylic resin, 3-6.5 parts of organic silicone oil, 0.5-1.5 parts of protective glue, 1-4 parts of polyoxyethylene stearate, 0.7-1.5 parts of sodium dodecyl benzene sulfonate, 0.2-0.45 part of lauroyl peroxide, 0.08-0.13 part of sodium bicarbonate, 1.5-3.5 parts of low-wax asphalt, 0.1-0.3 part of dodecanol ester, 0.5-1 part of ethyl acetate and 15-29 parts of deionized water. The exterior wall protecting coating provided by the invention has high weather resistance, strong adhesion and high water resistance, is suitable for coating an exterior wall of a building, has an excellent building beautifying effect, and can protect the building from invasion of outside air, ultraviolet light, rainwater and chemical substances so as to prolong the service life of the exterior wall.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a coating for protecting exterior walls and a preparation method thereof. Background technique [0002] Silicone acrylic resin is a copolymer emulsion of organosiloxane and acrylate. It is an environmentally friendly paint base resin and can be compounded with various organic resins in a certain proportion. Silicone acrylic resin is environmentally friendly and safe, has excellent weather resistance and gloss, and the coating surface of the prepared coating is easy to clean and has high stability. [0003] The currently used exterior wall coatings have low weather resistance, adhesion, and anti-aging properties, and the service life of the coatings is short, and they are easily damaged by ultraviolet rays, rain and chemical substances. Contents of the invention [0004] Technical problem to be solved: Aiming at the shortcomings of existing exterior wall coatings, the invention provide...
