Description

Technical Field

[0001] The utility model relates to the technical field of indoor decoration materials, in particular to a wall self-adhesive composite material which is convenient for removing adhesive. Background Art

[0002] With the development of the times, wall decoration materials such as wallpaper, wall cloth, wall stickers, etc., which are installed on the wall by various adhesives, are becoming more and more popular. These adhesives used to install wallpaper, wall cloth, and wall stickers, such as glutinous rice glue, water-based glue, solvent glue, or self-adhesive glue, will penetrate into the wall base. For walls with putty powder as the base, before installing wallpaper, wall cloth, and wall stickers, a curing agent, that is, "wallpaper base film" paint, is generally used to cure the wall base to a certain extent. Although this enhances the adhesive strength of the wallpaper, wall cloth; but when removing wallpaper, wall cloth, or wall stickers, the wall base will be hardened. When applying decorative materials, the base wall is often damaged, resulting in large areas of potholes or peeling of the wall. If wallpaper or wall cloth or wall stickers need to be pasted again, the base wall needs to be filled and polished with putty powder again. A large amount of decorative dust and garbage is generated in the process, which pollutes the environment and is time-consuming and labor-intensive. In order to solve the limitations of the wall curing agent commonly used for wallpaper, wall cloth and wall stickers, the applicant is committed to developing a self-adhesive composite material for walls that is easy to remove adhesives, so as to solve the problem that the wall base will fall off when removing wall materials, thereby protecting the wall base.
