[0002] Home decoration ceiling is a common part of home decoration. The classification of ceiling varies according to the material of the decorative panels. It occupies a very important position in the entire room decoration. Proper decoration of the room ceiling can not only beautify the indoor environment, but also create a colorful indoor space artistic image.
[0003] Newly renovated buildings have high indoor humidity. The gypsum board ceiling seals the upper space, causing long-term accumulation of moisture in the upper space. Since the gypsum board has poor moisture resistance, it will expand and contract when exposed to moisture. Traditional caulking materials have poor moisture resistance and deformation resistance, resulting in cracking. This not only seriously affects the aesthetics of the ceiling, but also moisture seeps into the room through the seams for a long time, causing objects to mold and breed bacteria, and making people feel uncomfortable, affecting their health.
