[0002] Wallpaper, also known as wall paper, is an interior decoration material used for wall pasting. It is widely used in interior decoration of residences, offices, guesthouses, and hotels. The material is not limited to paper, but also includes other materials. Wallpaper is divided into many categories, such as laminated wallpaper, coated wallpaper, embossed wallpaper, etc. The base paper is usually produced from bleached chemical wood pulp, and then processed through different processes, such as coating, printing, embossing or surface coating, and finally cut and packaged before leaving the factory. It has certain strength, toughness, beautiful appearance and good water resistance.

[0003] In the prior art, after the wallpaper is laminated with PET aluminum-coated paper and PVC color-printed paper by a solvent-free laminating machine, the paper fastness, hiding rate, waterproof rate, and moisture resistance of the composite wallpaper can be effectively increased, so that it no longer needs to be torn by hand during use and can be used directly, thereby not only saving use time but also protecting the environment. However, the composite wallpaper has the following technical problems during use: (1) The existing wallpaper has poor elasticity during use, so that the pattern on the color paper will be wrinkled during the pasting process, which greatly affects the appearance of the wallpaper after pasting. (2) The existing wallpaper does not have a noise reduction effect, has a relatively single function, and has a poor practical effect.

[0004] Therefore, a non-adhesive composite wallpaper is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figure 1-4 , the utility model provides a technical solution: a non-adhesive composite wallpaper, comprising a PET aluminized paper 1, on which a PVC color printing paper 2 is installed;

[0024] The PVC color printing paper 2 includes a base layer 25, the bottom side of the base layer 25 is fixedly installed on the PET aluminized paper 1, a noise reduction layer 24 is fixedly installed on the base layer 25, a pattern layer 23 is fixedly installed on the noise reduction layer 24, an anti-wrinkle layer 22 is fixedly installed on the pattern layer 23, and a temperature-sensitive gradient layer 21 is fixedly installed on the anti-wrinkle layer 22. After the PET aluminized paper 1 and the PVC color printing paper 2 are compounded together by a solvent-free compounding machine, the paper fastness, hiding rate, waterproof rate, and moisture resistance of the wallpaper are increased, so that it is no longer necessary to tear it by hand when using it, and it can be used directly, thereby not only saving use time, but also protecting the environment. At the same time, the antibacterial layer 3, the temperature-sensitive gradient layer 21, the anti-wrinkle layer 22, the pattern layer 23, the noise reduction layer 24 and the base layer 25 work together to increase the use function of the wallpaper, thereby effectively supplementing the practicality of the wallpaper when in use.

[0025] Reference Figure 2In the utility model, an antibacterial layer 3 is fixedly installed on the bottom side of the PET aluminized paper 1. The antibacterial layer 3 is a coating made of a polymer quaternary ammonium salt, and its width ranges from 1 to 1.3 mm. In order to avoid that the PET aluminized paper 1 will be posted for a long time, due to the poor air permeability of existing wallpapers, after the wallpaper is posted for a long time, water vapor will be generated and unable to dissipate between the PET aluminized paper 1 and the wall, and then bacteria will be bred. Therefore, the characteristics of the antibacterial layer 3 can be used to effectively prevent bacteria from breeding on the composite wallpaper.

[0026] Reference Figure 3 In the utility model, the wrinkle-proof layer 22 includes a diene elastic fiber 222, the bottom side of the diene elastic fiber 222 is fixedly mounted on the upper surface of the pattern layer 23, a silicone high-elastic coating 221 is fixedly mounted on the diene elastic fiber 222, the upper surface of the silicone high-elastic coating 221 is fixedly mounted on the bottom side of the temperature-sensitive gradient layer 21, the width of the silicone high-elastic coating 221 ranges from 45 microns to 63 microns, and the width of the diene elastic fiber 222 ranges from 20 microns to 35 microns.

[0027] Reference Figure 4 In the utility model, the noise reduction layer 24 includes a sound-absorbing cotton 243, the bottom side of the sound-absorbing cotton 243 is fixedly installed on the upper surface of the base layer 25, a plurality of sound-absorbing holes 242 are fixedly opened on the upper surface of the sound-absorbing cotton 243, a glue sponge 241 is fixedly installed on the upper surface of the plurality of sound-absorbing holes 242, and the upper surface of the glue sponge 241 is fixedly installed on the bottom side of the pattern layer 23. The width of the glue sponge 241 is between 20 microns and 33 microns, and the width of the sound-absorbing cotton 243 is between 47 microns and 52 microns. When the noise in the PVC color printing paper 2 is large, the glue sponge 241 will absorb the sound in the air, and then transmit the sound from the cavity in the middle of the sound-absorbing hole 242 to the sound-absorbing cotton 243. After being transmitted to the sound-absorbing cotton 243, the sound is completely absorbed by the sound-absorbing cotton 243, thereby effectively reducing the noise in the room.

[0028] Reference Figure 2 In the present invention, the temperature-sensitive gradient layer 21 is made of diarylethene material, and its width is eight to ten microns. By setting the temperature-sensitive gradient layer 21, when the indoor temperature changes, the color of the pattern layer 23 will gradually change, thereby increasing the beauty of the pattern.

[0029] The working principle is as follows: after the PET aluminum-plated paper 1 and the PVC color-printed paper 2 are compounded together by a solvent-free compounding machine, the paper fastness, hiding rate, waterproof rate, and moisture resistance of the wallpaper are increased, so that it is no longer necessary to tear it by hand when using it, and it can be used directly, thereby not only saving use time, but also protecting the environment. After the composite wallpaper processed by the PET aluminum-plated paper 1 and the PVC color-printed paper 2 is pasted on the wall, the diene elastic fiber 222 is used to make the outer surface of the pattern layer 23 have a good elastic anti-wrinkle effect, and then the organic silicon high-elastic coating 221 is used to make the outer surface of the composite wallpaper have a good elastic anti-deformation effect. In summary, the above effects are combined, so that when the PVC color-printed paper 2 is pasted on the wall, the surface of the PVC color-printed paper 2 will not wrinkle, thereby affecting the beauty of the PVC color-printed paper 2 after pasting. It can also increase the fastness of the PET aluminized paper 1. At the same time, by using the setting of the temperature-sensitive gradient layer 21, when the indoor temperature changes, the color of the pattern layer 23 will gradually change, thereby increasing the beauty of the pattern. At the same time, when the noise is large in the PVC color-printed paper 2, the glue sponge 241 will absorb the sound in the air, and then transmit the sound from the hole in the middle of the sound-absorbing hole 242 to the sound-absorbing cotton 243. After being transmitted to the sound-absorbing cotton 243, the sound is completely absorbed by the sound-absorbing cotton 243, thereby effectively reducing the indoor noise. In order to avoid the PET aluminized paper 1 after being posted for a long time, due to the poor air permeability of the existing wallpaper, after the wallpaper is posted for a long time, water vapor will be generated and cannot dissipate between the PET aluminized paper 1 and the wall, and then bacteria will breed. The special properties of the antibacterial layer 3 can effectively prevent bacteria from breeding on the composite wallpaper.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
