[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] Reference Figures 1 to 3A thermal insulation clean board according to an embodiment of the utility model comprises a substrate 100 and two layers of panels 200, the two layers of panels 200 are symmetrically arranged on both sides of the substrate 100, and a heat reflection layer 300 is arranged between the substrate 100 and the panels 200; wherein the heat reflection layer 300 comprises an EPP board 310 and thermal insulation particles 320, in the cross section of the EPP board 310, the EPP board 310 is wavy and fixedly connected between the substrate 100 and the panels 200, a cavity 330 is provided between the EPP board 310 and the substrate 100 and the panels 200, the thermal insulation particles 320 are built in the cavity 330, and the interior of the cavity 330 is vacuum, specifically, the two layers of EPP boards 310 are symmetrically arranged with the substrate 100 as the center.

[0030] Reference Figure 1 The EPP board 310 of the heat reflective layer 300 in the thermal insulation clean board in the present technical solution has the property of low thermal conductivity, which can effectively reduce the heat transfer efficiency. At the same time, the wavy EPP board 310 also reflects the heat radiation, so that the heat radiation radiated to the concave position of the EPP board 310 can be reflected back. Specifically, the heat radiation from the room is reflected to the room, and the heat radiation from the outside is reflected to the outside, thereby reducing the heat exchange between the indoor and outdoor areas, avoiding the external heat from affecting the indoor temperature, and avoiding the indoor heat from being lost to the outdoors. In addition, the thermal insulation particles 320 hidden in the cavity 330 can also hinder the transfer of heat, reduce the efficiency of heat transfer to the other side, and cooperate with the EPP board 310 to achieve the purpose of reducing the indoor and outdoor heat exchange efficiency. On the other hand, ensuring a high vacuum state in the cavity 330 can also well reduce heat transfer.

[0031] In summary, by utilizing the low thermal conductivity of the EPP board 310 and the vacuum cavity 330 formed by the corrugated EPP board 310, the heat reflection layer 300 close to the indoor side can effectively block the heat in the room from dissipating to the outdoors. At the same time, the heat reflection layer 300 close to the outdoor side can effectively block the heat outside from transferring to the indoor room, thereby improving the stability of the indoor temperature and improving the thermal insulation effect.

[0032] In order to further improve the reflection effect of thermal radiation, refer to Figure 1 In cross section, the cross-sectional curve of the arc-shaped area of ​​the EPP board 310 is in a parabolic shape. The arc-shaped area in a parabolic shape can constitute a heat radiation reflection surface, which can better reflect heat radiation and improve the heat preservation effect.

[0033] Furthermore, in order to improve the thermal insulation effect, the thermal insulation particles 320 are made of EPP material with low thermal conductivity. Preferably, in order to effectively utilize the space in the cavity 330 , the thermal insulation particles 320 are spherical so that more thermal insulation particles 320 can be added to the cavity 330 .

[0034] In the production of the thermal insulation clean board, it is necessary to cut it according to the actual size requirements, and then seal the edges after cutting to make the internal cavity 330 a closed space. Figure 1 The heat-insulating clean board further comprises an edge banding strip 500, which is bonded and fixed to the edges of the substrate 100, the panel 200 and the heat-reflecting layer 300 to seal the space between the two panels 200. Figure 2 In some embodiments, a plurality of through holes 340 are provided on the EPP board 310, and a plurality of cavities 330 are connected through the through holes 340. An air extraction hole 210 is provided on the panel 200, and the air extraction hole 210 penetrates and is connected to the cavity 330. A rubber gas plug 211 is detachably installed on the air extraction hole 210. After the processing is completed according to the actual size, the cavity 330 is evacuated by connecting a vacuum pump at the air extraction hole 210. Specifically, the air extraction hole 210, the plurality of cavities 330 and the through holes 340 are connected. The cavities 330 on both sides of the substrate 100 are relatively independent. The cavities 330 on both sides of the substrate 100 are evacuated from the air extraction holes 210 on the two layers of the panel 200, respectively, so that the vacuum degree of the cavity 330 is improved, and the heat preservation effect is improved. After the vacuuming is completed, the rubber gas plug 211 can be directly inserted to ensure the airtightness of the cavity 330.

[0035] It is worth mentioning that, refer to Figure 1 and Figure 2 In the two-layer panel 200, one layer of the panel 200 is detachably connected with the decorative plate 400, and the other layer of the panel 200 is fixedly connected to the surface of the wall, and the side of the panel 200 away from the substrate 100 is provided with a plurality of slots 220, and the plurality of slots 220 are arranged at intervals along the edge of the panel 200, and the decorative plate 400 is provided with a plurality of elastic buckles 410 on the side facing the panel 200, and the elastic buckles 410 and the slots 220 correspond one to one, and the elastic buckles 410 and the slots 220 are snap-fitted. In the actual assembly process, the construction personnel can arbitrarily select one side of the panel 200 to be fixedly connected to the surface of the wall, and the connection method can be selected according to actual needs, and the panel 200 away from the wall is installed with the decorative plate 400 by snap-fitting, which improves the aesthetics. At the same time, the detachable installation method can also provide users with decorative plates 400 of different styles for installation. In addition, to facilitate installation, the elastic deformation of the elastic buckle 410 makes it easy to insert the elastic buckle 410 into the slot 220 or to remove it from the slot 220 .

[0036] The side of the decorative plate 400 facing the panel 200 is covered with a foam plastic layer 420, and the foam plastic layer 420 is in contact with the surface of the panel 200. The foam plastic layer 420 has a certain sound insulation effect and can also provide a sound insulation effect for the heat preservation clean board in the embodiment of the utility model.

[0037] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
