Description

Technical Field

[0001] The utility model relates to the technical field of wall panels, in particular to a bonding type lightweight wall panel. Background Art

[0002] Lightweight wall panels, also often called lightweight partition panels or lightweight walls, are a type of interior and exterior wall partition material widely used in the construction industry. Its main features are light weight, high strength, easy installation and good functionality.

[0003] There are two ways to connect adhesive lightweight wall panels: one is to bond them on site with adhesives, and the other is to use adhesives set on the back of the wall panels at the factory. Adhesives cannot be guaranteed during on-site construction, and formaldehyde is likely to exceed the standard. However, wall panels with self-adhesive adhesives are inconvenient during actual construction. When the protective layer of the wall panel adhesive is torn off, the protective layer will accumulate below, so that the bottom of the wall panel needs to be lifted up for construction, so the protective layer needs to be separated in the middle. To this end, we provide an adhesive lightweight wall panel to solve the above problems. Utility Model Content

[0004] 1) Technical issues solved

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a bonding type lightweight wallboard.

[0006] 2) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adhesive lightweight wall panel, comprising a wall panel, an adhesive layer is provided on the back of the wall panel, a protective layer is provided on the side of the adhesive layer away from the wall panel, the protective layer protrudes outward on all sides and covers the outer circle of the adhesive layer, a tear groove penetrating the protective layer is provided on the surface of the protective layer, and the number of the tear grooves is equidistantly distributed.

[0008] Furthermore, the rear side of the protective layer is covered with a secondary connection film, and the secondary connection film covers the rear end of the tear groove.

[0009] Furthermore, the bonding strength between the secondary connection film and the protective layer is divided into two types, and the bonding strength close to the first-torn side is greater than the bonding strength of the last-torn side.

[0010] Furthermore, the protective layer is provided with protrusions on both sides of the tearing groove, and two adjacent protrusions are symmetrically arranged with respect to a vertical line of the tearing groove.

[0011] Furthermore, a groove is provided at the rear end of the wall panel, and the adhesive layer fills the inside of the groove and extends out of the groove to cover the entire wall panel.

[0012] Furthermore, the cross-sectional shape of the groove is an isosceles trapezoid and a notch is provided in the middle of the short side of the parallel sides, and the distance between the two parallel sides is equal to the thickness of the adhesive layer located on the rear side of the wallboard.

[0013] Furthermore, the protective layer and the secondary connection film are both made of opaque plastic film.

[0014] Three beneficial effects:

[0015] Compared with the prior art, the adhesive lightweight wallboard has the following beneficial effects:

[0016] 1. The utility model separates the topmost protective layer, tilts the wall panel so that the bottom end contacts the wall surface, and the wall panel is bonded to the wall surface through the adhesive layer. At this time, the protective layer at the bottom of the top protective layer is broken through the tearing groove, so that the protective layers can be separated, and the tilt angle of the wall panel is changed. The multiple protective layers are separated in sequence by repeating the action, thereby reducing the accumulation of the protective layer to be separated when the protective layer is separated from the wall panel, which hinders the separation of the protective layer.

[0017] 2. The utility model covers the rear side of the protective layer with a secondary connection film, and the secondary connection film covers the rear end of the tear groove. The tear groove will cause the adhesive layer to contact with the air, which will cause part of the adhesive layer to oxidize and fail. The secondary connection film can prevent the adhesive layer from contacting with the air. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] 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.

[0024] like Figure 1-4 As shown, the utility model provides a technical solution: an adhesive lightweight wall panel, comprising a wall panel 1, an adhesive layer 2 is provided on the back of the wall panel 1, a protective layer 3 is provided on the side of the adhesive layer 2 away from the wall panel 1, the protective layer 3 protrudes outward on all sides and covers the outer circle of the adhesive layer 2, and a tear groove 4 penetrating the protective layer 3 is provided on the surface of the protective layer 3. The number of the tear grooves 4 is multiple, and the multiple tear grooves 4 are equidistantly distributed. Tearing the protective layer 3 can break along the tear grooves 4, so that the entire protective layer 3 can be divided into multiple pieces, thereby avoiding the accumulation of the protective layer and causing inconvenience in installation.

[0025] The rear side of the protective layer 3 is covered with a secondary connecting film 5, which covers the rear end of the tear groove 4. The tear groove 4 will cause the adhesive layer 2 to contact with the air, which will cause part of the adhesive layer 2 to oxidize and fail. By setting the secondary connecting film 5, the adhesive layer 2 can be prevented from contacting with the air.

[0026] There are two types of bonding strength between the secondary connecting film 5 and the protective layer 3. The bonding strength on the side that is torn first is greater than the bonding strength on the side that is torn later. With this arrangement, the secondary connecting film 5 can be torn apart together with the protective layer 3 to avoid the need to tear the secondary connecting film repeatedly.

[0027] The protective layer 3 is provided with protrusions 6 on both sides of the tearing groove 4, and the two adjacent protrusions 6 are symmetrically arranged about the vertical line of the tearing groove 4. By setting the protrusions 6, it is convenient to tear the protective layer 3. By setting the symmetrical arrangement, after separating one layer of protective layer 3, the next layer of protective layer 3 can be continuously separated from this side, thereby reducing operating actions and improving work efficiency.

[0028] A groove 7 is provided at the rear end of the wall panel 1, and the adhesive layer 2 is filled in the groove 7 and extends out of the groove 7 to cover the entire wall panel 1. This arrangement can increase the strength between the wall panel 1 and the adhesive layer 2.

[0029] The cross-sectional shape of the groove 7 is an isosceles trapezoid with a notch in the middle of the short parallel sides. The distance between the two parallel sides is equal to the thickness of the adhesive layer 2 at the rear side of the wallboard 1. This arrangement can increase the thickness of the adhesive layer 2.

[0030] The materials of the protective layer 3 and the secondary connection film 5 are both opaque plastic films, and such a configuration can prevent the adhesive layer from being ineffective due to light.

[0031] Working principle: Separate the topmost protective layer 3, tilt the wall panel 1 so that the bottom end contacts the wall, and the wall panel 1 is bonded to the wall through the adhesive layer 2. At this time, the protective layer 3 at the bottom of the top protective layer 3 is broken through the tear groove 4, so that the protective layer 3 can be separated, and the tilt angle of the wall panel 1 is changed. Repeat the action to separate multiple protective layers 3 in sequence, thereby reducing the accumulation of the protective layer 3 that is separated first when the protective layer 3 is separated from the wall panel 1 at the protective layer 3 to be separated, which hinders the separation of the protective layer 3.
