In the description of the present invention, it is to be understood that the terms "mounted," "connected," and "connected" are used broadly and are defined as, for example, either fixedly connected, detachably connected, or integrally connected, unless otherwise explicitly stated or limited; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in a specific case to those of ordinary skill in the art.

In the description of the present invention, it should be further understood that the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the machine or element so referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention.

Referring to fig. 1, the foam carbon soundproof door according to the embodiment of the present invention includes a foam carbon door core 1, four frame strips 2 and two facing plates 3, the four frame strips 2 are connected to each other to form a frame surrounding the foam carbon door core 1, the two facing plates 3 are respectively located on the front and rear sides of the foam carbon door core 1, the facing plates 3 are bonded to the foam carbon door core 1 and the frame strips 2 through polyurethane foam, the foam carbon door core 1 has better sound insulation performance than a conventional shaving board door core, and has improved fire resistance, less deformation, aging and shrinkage, better stability, moisture resistance, mold resistance, and low water absorption, no formaldehyde release due to the use of polyurethane foam, environmental protection, no influence of moisture, good drought resistance and good heat retention effects, and the frame strips 2 can be used as an outer skeleton structure around the door core, so that the soundproof door is easy to install and use, also has a good structure.

Referring to fig. 1 and 2, for example, the frame material strip 2 on the lower side of the foam carbon door core 1 is provided with a groove 21 on the bottom side, a smoke barrier strip 22 is connected in the groove 21, and the smoke barrier strip 22 made of rubber, silica gel and other materials can prevent dense smoke from entering from a gap below a door body in case of fire, so as to ensure the safety of the fire.

Referring to fig. 1, exemplarily, the frame material strips 2 on the left and right sides of the foam carbon door core 1 are respectively provided with a hinge 23 and a door lock 24, the two frame material strips 2 respectively bear the door lock 24 and the hinge 23, the door core structure is not required to be stressed, the door core is more durable, the connection between the hinge 23 and the door lock 24 is the same as that of the existing door body, a special mode is not required to be adopted for installation, the installation is convenient, and the veneer 3 is provided with an installation hole corresponding to the door lock 24.
