In addition, the meaning of "and/or" appearing throughout includes three juxtapositions, exemplified by "A and/or B" including either A or B or both A and B. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

In view of this, the present invention provides a wallpaper, and aims to provide a wallpaper which is convenient to replace and not easy to damage a wall. Referring to fig. 1, the wallpaper provided by the present invention has an inner side close to a wall and an outer side away from the wall, and includes a first adhesive layer 1, a base layer 2, a second adhesive layer 3, and a surface layer 4, which are sequentially stacked from inside to outside, wherein the outer side of the base layer 2 is provided with a smooth surface 21, and the second adhesive layer 3 is a removable back adhesive layer. Glue basic unit 2 on the wall through first glue film 1, the outside of basic unit 2 sets up smooth surface 21, reuse second glue film 3 bonds top layer 4 on smooth surface 21, when changing the wall paper, only need to tear top layer 4 and second glue film 3 from smooth surface 21, top layer 4 and the second glue film 3 of renewal, because second glue film 3 is for can moving the gum layer, its adhesion dynamics is no longer inferior to ordinary gum, can freely tear and do not leave the vestige when tearing, make the wall paper bond firmly when using, change easily and do not leave the gum mark during the change, both realized pleasing to the eye effect, save manpower and materials when changing again.

Preferably, the smooth surface 21 of the base layer 2 can be set to be white, and since the wall surface is generally white, the base layer 2 does not need to be torn off after being adhered to the front surface through the first glue layer 1, so that the color consistency of the wall surface can be maintained.

The material of the first adhesive layer 1 is not limited in the invention, as long as the base layer 2 can be firmly adhered to the wall surface; preferably, in the embodiment of the present invention, the first glue layer 1 is a starch glue layer or a glutinous rice glue layer. Starch glue and glutinous rice glue are purely natural environment-friendly adhesives: the glutinous rice glue is a high-performance adhesive, takes pure natural edible glutinous rice as a main raw material, is also a pure natural glutinous rice adhesive which is convenient to use, can be used by adding water and stirring uniformly during glue opening, does not need to add thickening mucilage, and has more excellent performance when thick and heavy wallpaper is pasted; the starch glue is combined with the technical achievement of the Japanese advanced chemical research institute, and takes modified starch as a main raw material. The first adhesive layer 1 is made of starch glue or glutinous rice glue, and is non-toxic, odorless, environment-friendly, healthy and good in bonding effect.

In order to meet the diversified requirements of modern people on wallpaper, in the embodiment of the present invention, referring to fig. 2, the surface layer 4 includes an adsorption layer 41 and a decoration layer 42, which are sequentially stacked from inside to outside, and the adsorption layer 41 is a nano activated carbon adsorption layer. The nano activated carbon adsorption layer can absorb harmful substances such as indoor formaldehyde, suspended particles and the like, and purify air; the decorative layer 42 can be provided with diversified patterns to meet the needs of consumers.

Further, referring to fig. 2, the surface layer 4 further includes a flame retardant layer 43, and the flame retardant layer 43 is disposed between the absorption layer 41 and the decoration layer 42. In modern life, various fire risks exist, the flame-retardant layer 43 is arranged between the adsorption layer 41 and the decoration layer 42, once a fire happens, the fire can be effectively prevented from spreading, and personal and property safety of users is protected.

The connection manner between the adsorption layer 41 and the flame retardant layer 43 and between the flame retardant layer 43 and the decoration layer 42 is not limited in the present invention, and preferably, third adhesive layers are disposed between the adsorption layer 41 and the flame retardant layer 43 and between the flame retardant layer 43 and the decoration layer 42. The adsorption layer 41 and the flame-retardant layer 43, and the flame-retardant layer 43 and the decorative layer 42 are bonded through the third adhesive layer, so that the method is simple and convenient.

Preferably, the third adhesive layer is an aqueous polyurethane adhesive layer. The aqueous polyurethane adhesive is an adhesive in which polyurethane is dissolved or dispersed in water, and some also refers to aqueous polyurethane or aqueous polyurethane. When the adhesive is used for bonding each layer, because free isocyanate is not contained, the adhesive is non-toxic, has little smell, is convenient to operate, and residual adhesive is easy to clean.

The present invention is not limited to the specific form of the decoration layer 42, and preferably, referring to fig. 2, the decoration layer 42 includes a mesh layer 421 and a see-through layer 422 which are sequentially stacked from inside to outside, the mesh layer 421 has a plurality of meshes, and the meshes are filled with photochromic materials. Photochromic materials are materials that change color when excited by a light source. See through the photochromic material that fills in the mesh through perspective layer 422 for the wall paper can demonstrate different colours according to the change of indoor light luminance, has increased the variety of wall paper on the one hand, alleviates visual fatigue, and on the other hand, when light is stronger, protection sunlight shines, guarantees safety.

In addition, as another embodiment of the present invention, the decoration layer 42 includes a mesh layer 421 and a transparent layer 422 which are sequentially stacked from inside to outside, the mesh layer 421 has a plurality of meshes, and the meshes are filled with magnetic powder. For users with children at home, the magnetic powder is filled in the meshes, the children can draw various patterns on wallpaper by using a magnetic pen, and the drawn patterns can be erased and reused.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
