[0002] With the rapid development of the paint industry, various special paints for interior walls emerge in endlessly. Manufacturers attract the attention of consumers in terms of color, material and safety. , usually prone to the following problems: the wall is prone to mildew or oxidation, causing the paint to fall off, especially during the rainy season in the south, when the air is humid, it is more likely to have mildew on the interior wall, and the water resistance is poor.
