In modern interior decoration, in order to keep warm in winter, people have come up with heating floors, and even wall panels that can heat themselves. However, traditional heating wall panels generally assemble keels, heating elements, tiles and other components on the wall. In this way, the integration level of heating wall panels is low, the installation is troublesome, the manufacturing and installation costs are high, and the heating is slow and uneven. The service life is short, it is not durable, and it is easy to damage. At the same time, there are also some heating wall panels on the market, which use PVC sheets or composite wooden sheets, which contain some substances harmful to the human body during the heating process. In terms of functionality, most of them only have the function of heating, not the role of heat preservation, and they are heavy and easy to deform.

[0020] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] like Figure 1 to Figure 2 The heating wall panel shown includes, from top to bottom, a surface decoration layer 1, an upper PPF composite fiber sheet 2, a graphene heating film 3, a pure aluminum reflective film 4, and a lower PPF composite fiber sheet 5. The graphene heating film 3 has two connection points, and the lower PPF composite fiber sheet 5 has two openings directly opposite to the connection points. The surface decoration layer 1 is selected from any one of cloth, PVC decorative film, PET decorative film, PETG decorative film, and PP decorative film. The surface decoration layer 1 covers the top surface and all sides of the upper PPF composite fiber sheet 2, and covers all sides and part of the bottom surface of the lower PPF composite fiber sheet 5, which plays a decorative role on the surface of the heating wall panel and has good stain resistance and heat resistance.

[0024] The PPF composite fiber material board is a board formed by a composite of polyester fiber, polypropylene fiber and glass fiber. It has the characteristics of environmental protection, light weight, waterproof, stable physical properties, and heat resistance and heat preservation. Using the PPF composite fiber material board as the main board of the heating wall panel has a good thermal insulation effect, and the wall panel has mild heat transfer and long-lasting heat preservation. The upper layer of the PPF composite fiber board 2 can be 3mm thick. The 3mm thickness can avoid the problem of slow heat transfer of the wall panel due to the excessive heat resistance of the PPF composite fiber material board itself. The lower layer of the PPF composite fiber board 5 is 7mm thick, so the thickness of the overall heating wall panel is about 10mm, which avoids the heavy feeling of the heating wall panel and will not occupy too much indoor space. While having good thermal insulation performance, the heating wall panel as a whole has an appropriate weight, and the wall panel installation has reliable safety. The thickness of the upper PPF composite fiber board 2 and the lower PPF composite fiber board 5 of the heating wall panel can be adjusted according to user needs or usage environment. However, the thickness of the upper PPF composite fiber board 2 should generally not be greater than the thickness of the lower PPF composite fiber board 5. The PPF composite fiber board should not be too thin. When the PPF composite fiber board is thin, it may experience slight thermal expansion after heating, resulting in slight undulations on the surface. At the same time, a thin PPF composite fiber board is not conducive to the thermal insulation of the heating wall panel, which increases the user's electricity energy consumption.

[0025] Below is the material testing of the 3mm upper PPF composite fiber sheet 2 and the 7mm lower PPF composite fiber sheet 5:

[0026]

[0027] At least one of the left side wall, the right side wall, the upper side wall and the lower side wall of the heating wall panel is provided with a splicing notch 8. The splicing notch 8 adopts an I-shaped groove or a spherical groove, which can meet a variety of different installation methods. The heating wall panel designed by the utility model can be directly closely spliced ​​on the wall surface, or a frame can be pre-installed on the wall surface and the heating wall panel can be installed on the frame. If the installation wall surface is not very flat, the surface decoration layer on the reserved splicing notch can be cut open, and an I-shaped fastener or a spherical fastener can be used to assist in the installation.

[0028] The heating wall panels designed by the present invention can be directly glued together by gluing each other. The size of the pure aluminum reflective film 4 is larger than that of the graphene heating film 3, and the size of the pure aluminum reflective film 4 is smaller than that of the lower PPF composite fiber board 5. The graphene heating film 3 and the pure aluminum reflective film 4 are directly bonded in the middle of the PPF composite fiber board. This method is easy to process and has low cost. In order to make the heating wall panels have a smaller thickness, a more precise fit, and a greater processing accuracy, the graphene heating film 3 can be embedded in the upper PPF composite fiber board 2, and the pure aluminum reflective film 4 can be embedded in the lower PPF composite fiber board 5. The method of embedding first and then bonding has better tightness, especially avoiding the problems of cracking of the internal glue layer and widening of the gaps that may be caused by long-term use of the heating wall panels.

[0029] As a further improvement of the present invention, two copper strips 9 are further provided on the bottom surface of the heating wall panel, and the copper strips 9 are parallel to the side of the heating wall panel and pass through the openings respectively.

[0032] S2. Evenly apply PUR glue on the surface of the pure aluminum reflective film 4 of the lower PPF composite fiber material plate 5 with holes, and then fit it with the graphene heating film 3.

Use a pressure roller to make it fit firmly, and wait for the glue to solidify before use;

[0033] S3, evenly apply PUR glue on one surface of the upper PPF composite fiber material plate 2, and fit it with the back plate with the graphene heating film 3, use a pressure roller to make it fit firmly, and after the glue is cured, set two copper strips 9 at the bottom of the wallboard, the copper strips 9 are parallel to the side of the wallboard and pass through the two lower openings 7 respectively, and according to user needs, splicing notches 8 are opened in the upper, lower, left and right side walls to obtain a semi-finished heating wallboard;

[0034] S4, using a coating machine to laminate and coat the surface decoration layer 1 on the surface of the semi-finished heating wall panel to obtain a finished heating wall panel.

Use a pressure roller to make it fit firmly. After the glue is cured, set two copper strips 9 at the bottom of the wallboard. The copper strips 9 are parallel to the side of the wallboard and pass through the two lower openings 7 respectively. According to user needs, splicing notches 8 are opened in the upper, lower, left and right walls to obtain a semi-finished heating wallboard;
