[0041] In some embodiments of the present invention, refer to Figure 2 and Figure 3 The middle layer 32 is integrally formed, including a thin plate 321 and a plurality of spaced pillars 322. The pillars 322 are vertical hollow cavity structures formed by the thin plate 321 through blistering. Specifically, after the mixed material is extruded into a cast film, a blistering cavity is formed by a blister roller. The pillars 322 are not penetrated at one end toward the second flame retardant layer 33, but penetrated toward the side of the thin plate 321. The pillars 322 are evenly spaced. The height ratio of the thin plate 321 to the pillars 322 is 1:3.5. The height ratio of the thin plate 321 to the pillars 322 is adjusted to further improve the supporting performance of the supporting layer. The middle layer 32 is formed by the thin plate 321 and the pillars 322 cooperating with each other to form a hollow layer. The pillars 322 are cavity structures, and two adjacent pillars 322 are spaced apart. Therefore, the middle layer 32 uses air as the heat transfer medium. The air heat transfer rate is low, which is convenient for reducing the heat conduction rate, thereby improving the thermal insulation performance of the reinforcing plate.

[0042] In some embodiments of the present utility model, referring to Figure 3 , the shape of the strut member 322 is any one of cylindrical, prismatic, and pyramidal. Preferably, the strut member 322 is cylindrical. The cylindrical strut member 322 has a lower production cost, is easy to manufacture a mold, has a higher support strength, is convenient for improving the support performance of the strut member 322, is convenient for improving the support performance of the central support layer 3, and further improves the support performance of the reinforcing plate.

[0043] In some embodiments of the present utility model, referring to Figure 3 , a heat-insulating material is filled between two adjacent strut members 322. The heat-insulating material is selected from any one or more of polypropylene foam material, polystyrene foam material, polyurethane foam material, aerogel, aluminum silicate, and silicon-based foam material. Specifically, the heat-insulating material is selected from polyurethane foam material.

[0044] In some embodiments of the present utility model, referring to Figure 1 and Figure 2 , the upper surface of the intermediate layer 32 is thermally melt-bonded to the first flame-retardant layer 31, and the lower surface of the intermediate layer 32 is thermally melt-bonded to the second flame-retardant layer 33. At least part of the edges of the first flame-retardant layer 31 and the second flame-retardant layer 33 protrude outward from the intermediate layer 32. The overlapping portion 4 is formed by thermally melt-bonding the parts of the second flame-retardant layer 33 and the first flame-retardant layer 31 that protrude outward from the intermediate layer 32.

[0045] In some embodiments of the present utility model, the main body A of the reinforcing plate is a polygon. Specifically, it can be a triangle, a quadrilateral, a pentagon, etc. In this embodiment, the main body A of the reinforcing plate is a quadrilateral. The overlapping portion 4 is formed on one side or multiple sides of the main body A of the reinforcing plate, and can be one side (linear), two sides (L-shaped), or three sides (匚). In this embodiment, it is two sides. Specifically, the adjacent two side edges of the first flame-retardant layer 31 and the second flame-retardant layer 33 protrude outward from the intermediate layer 32. The overlapping portion 4 is formed by thermally melt-bonding the parts of the second flame-retardant layer 33 and the first flame-retardant layer 31 that protrude outward from the intermediate layer 32. The overlapping portion 4 is formed on two adjacent sides of the main body A of the reinforcing plate. The overlapping portion 4 is specifically an L-shaped overlapping wing thin sheet formed by bonding the parts of the second flame-retardant layer 33 and the flame-retardant layer 31 that exceed the main body A of the reinforcing plate, which is convenient for better splicing of adjacent waterproof aluminum heat-insulating fiber reinforcing plates. In addition, since the overlapping portion 4 is relatively thin and easy to cut, in actual use, the user can cut off the unnecessary part of the overlapping wing of the overlapping portion 4 as needed.

[0046] In some embodiments of the present invention, the upper and lower surfaces of the middle layer 32 are respectively completely covered by the flame retardant layer 1 31 and the flame retardant layer 2 33. In some specific embodiments of the present invention, the flame retardant layer 1 31, the middle layer 32, and the flame retardant layer 2 33 are all rectangular, and the edges are vertically aligned.

[0047] In some embodiments of the present invention, refer to Figure 1 and Figure 4 The overlap width d is 95-105mm, specifically, the overlap width d is 100mm. The width of the overlap 4 is adjusted to facilitate better splicing of adjacent reinforcing plates without affecting the supporting strength of the central supporting layer 3 on the reinforcing plate. The thickness of the overlap 4 is 0.3-2mm, specifically, the thickness of the overlap 4 is 1mm. The thickness of the overlap 4 is adjusted. When the thickness of the overlap 4 is too large, adjacent reinforcing plates are not easy to overlap. When the thickness of the overlap 4 is too small, adjacent reinforcing plates are not firmly connected. With the thickness of the overlap 4, on the one hand, the reinforcing plates are easy to overlap and the overlap is relatively firm.

[0048] In some embodiments of the present invention, refer to Figure 1 and Figure 2 The flame retardant layer 1 31 is selected from any one of flame retardant fiber-added polypropylene sheet and flame retardant fiber-added polyvinyl chloride sheet, specifically flame retardant fiber-added polyvinyl chloride sheet; the flame retardant layer 2 33 is selected from any one of flame retardant fiber-added polypropylene sheet and flame retardant fiber-added polyvinyl chloride sheet, specifically flame retardant fiber-added polyvinyl chloride sheet, and the flame retardant fiber-added polyvinyl chloride sheet is a flame retardant fiber-added polyvinyl chloride mixed material extruded cast film; the flame retardant fiber-added polyvinyl chloride has good waterproof performance, which is convenient for providing the waterproofness of the flame retardant layer 1 31, thereby improving the waterproofness of the central support layer 3. At the same time, the flame retardant fiber-added polyvinyl chloride contains fibers, which is convenient for cooperating with the middle layer 32 to further improve the strength of the central support layer 3.

[0049] In some embodiments of the present invention, refer to Figure 1 and Figure 2 The thickness ratio of the flame retardant layer 1 31, the middle layer 32, and the flame retardant layer 2 33 is (0.8-1):(4-4.5):(0.8-1), specifically 0.8:4.5:0.8. The thickness ratio of the flame retardant layer 1 31, the middle layer 32, and the flame retardant layer 2 33 is adjusted to take into account the three aspects of cost, heat preservation, and support, thereby better playing the role of the central support layer 3 in the composite material board.

[0050] In some embodiments of the present invention, refer to Figure 1 and Figure 2The upper surface of the central support layer 3 is bonded to the insulation layer 1, and the lower surface of the central support layer 3 is bonded to the insulation layer 2.

The insulation layer 1 is aluminum foil, and the emissivity of the aluminum foil is 95-99%, specifically, the emissivity of the aluminum foil is 99%; the insulation layer 2 is aluminum foil, and the emissivity of the aluminum foil is 95-99%, specifically, the emissivity of the aluminum foil is 99%. The insulation layer 1 and the insulation layer 2 are convenient for reflecting radiant heat, forming a reflective cavity, which helps to block the reflection of thermal radiation, block the heat transmission path, and provide thermal insulation of the reinforcement plate. Aluminum foil is a metal material, and its surface reacts quickly to changes in room temperature, which can reduce condensation on the surface.

[0051] In some embodiments of the present invention, refer to Figure 1 and Figure 2 The height of the middle layer 32 can be adjusted according to the thermal resistance requirements. The thickness of the reinforcing plate is greater than or equal to 4 mm. The thickness ratio of the thermal insulation layer 1, the central support layer 3, and the thermal insulation layer 2 is (0.1-0.2): (5.6-6.5): (0.1-0.2), specifically 0.1: 6.1: 0.1; specifically, the thickness of the reinforcing plate is 6.3 mm, the thickness of the thermal insulation layer 1 is 0.1 mm, and the thickness of the thermal insulation layer 2 is 0.1 mm; the thickness of the flame retardant layer 1 31 is 0.8 mm; the thickness of the middle layer 32 is 4.5 mm; and the thickness of the flame retardant layer 2 33 is 0.8 mm.
