[0030] The following details the specific implementation manners of the present application with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustrating and explaining the present application, and are not intended to limit the present application.

[0031] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0032] The first exemplary embodiment of the present application provides a roofing composite panel, as Figure 1 shown, the roofing composite panel 3 includes a waterproof coiled material 301, an insulation layer 302, and a metal plate 303 that are sequentially stacked from top to bottom. The waterproof coiled material 301, the insulation layer 302, and the metal plate 303 are formed into a whole by an adhesive, and the adhesive uses a polybutadiene rubber powder modified epoxy resin adhesive.

[0033] In this solution, by using a polybutadiene rubber powder toughened and modified epoxy resin adhesive as the adhesive for the roofing composite panel, the adhesive has high bonding strength, good toughness, and excellent high-temperature and high-humidity resistance performance. It can well meet the bonding between different materials of the composite panel, and is suitable for exposed environments, which can improve the overall weather resistance and wind resistance of the exposed roofing system.

[0034] Further, the binder is prepared by including bisphenol A epoxy resin, polybutadiene rubber powder, diisocyanate, epoxy soybean oil, maleic anhydride grafted asbestos fiber, and filler. Under the action of diisocyanate and catalyst, the terminal carboxyl groups on the polybutadiene rubber chemically bond with the modified epoxy resin to form a block copolymer containing flexible segments, increasing the high-temperature and high-humidity resistance and toughness of the binder; at the same time, epoxy soybean oil is used to surface-modify the maleic anhydride-modified asbestos fiber, thereby improving the hydrophobic property of the epoxy resin binder and also enhancing its toughness.

[0035] The transverse two ends of the roof composite panel 3 are respectively formed as a splicing male edge part 304 and a splicing female edge part 305. The part of the metal plate 303 located at the splicing female edge part 305 is formed as a female edge overlapping part 3031 extending out of the edge of the heat insulation layer 302. The heat insulation layer 302 includes a first heat insulation material layer 3021 and a second heat insulation material layer 3022 that circumferentially wraps the first heat insulation material layer 3021. At least the second heat insulation material layer 3022 is provided at the parts of the heat insulation layer 302 located at the splicing male edge part 304 and the splicing female edge part 305. In other words, the second heat insulation material layer 3022 is used to seal the edge of the first heat insulation material layer 3021.

[0036] In Figure 1 In the illustrated embodiment, the female edge overlapping part 3031 is formed as a female edge groove part, and the splicing male edge part 304 is formed as a male edge protruding part. When it is necessary to overlap one roof composite panel 3 on another roof composite panel 3, the protruding part of the male edge protruding part of one roof composite panel 3 can be inserted into the female edge groove part.

[0037] Further, the part of the metal plate 303 located at the splicing male edge part 304 extends to form an upturned part 3032, and the upturned part 3032 abuts against the side wall of the second heat insulation material layer 3022, thereby locally wrapping the bottom of the second heat insulation material layer 3022 to enhance the structural strength.

[0038] In an optional or preferred embodiment, the first heat insulation material layer 3021 is composed of a fiber material, such as rock wool material or glass wool material, and the second heat insulation material layer 3022 is composed of a polyurethane material.

[0039] In an optional or preferred embodiment, the waterproof coiled material 301 includes a first waterproof material layer, a fiber reinforcement layer, a second waterproof material layer, and a non-woven fiber layer that are sequentially stacked up and down. Among them, TPO material or PVC material can be selected as the first waterproof material layer and the second waterproof material layer. At the same time, one or more of polyester fiber, nylon fiber, and carbon fiber can be selected as the fiber reinforcement layer, thereby improving the tensile and tear resistance of the waterproof coiled material 301. In addition, polyester non-woven fabric or the like can be selected as the non-woven fiber layer, thereby enhancing the bonding strength between the waterproof coiled material 301 and the heat insulation layer 302.

[0040] The waterproof coiled material 301 in this embodiment is a special composite waterproof coiled material, which has high tensile and tear strength. And the non-woven fiber layer as the backing layer can have a better bonding effect with the thermal insulation layer 302, thereby improving the anti-peeling ability of the waterproof coiled material 301 and making the product itself have better bonding strength and wind resistance effect.

[0041] In an alternative or preferred embodiment, as Figure 1 shown, the metal plate 303 is a profiled metal plate, and the metal plate 303 protrudes downward to form a plurality of grooves, and the second thermal insulation material layer 3022 is filled in the grooves.

[0042] In an alternative or preferred embodiment, as Figure 1 shown, the thermal insulation layer 302 includes a first thermal insulation material layer 3021 and a second thermal insulation material layer 3022 that circumferentially wraps the first thermal insulation material layer 3021. The part of the thermal insulation layer 302 located at the splicing male edge part 304 and the splicing female edge part 305 is at least provided with the second thermal insulation material layer 3022. In this way, the second thermal insulation material layer 3022 is used to seal the edge of the first thermal insulation material layer 3021. On the one hand, it can enhance the overall structural strength of the entire roof composite panel 3. For example, using a relatively rigid material as the second thermal insulation material layer 3022 is beneficial to reducing the damage risk during transportation and construction. On the other hand, the second thermal insulation material layer 3022 can isolate rainwater or water vapor in the air from entering the first thermal insulation material layer 3021 to prevent the reduction of the thermal insulation effect.

[0043] It should be noted that in this embodiment, fiber materials such as rock wool and glass wool can be used as the first thermal insulation material layer 3021, which has an ideal thermal insulation effect and low cost. At the same time, foaming materials such as polyurethane can be used as the second thermal insulation material layer 3022, which has low preparation difficulty and good sealing effect and is suitable for the integrated production of the thermal insulation layer 302.

[0044] As Figures 2 to 4As shown in the figure, the second exemplary embodiment of the present application provides a roofing system, which includes a first connecting component 1, a second connecting component 2, and a plurality of roofing composite panels 3 for splicing and laying on the roof. Among them, the roofing composite panel 3 includes a waterproof coiled material 301, a thermal insulation layer 302, and a metal plate 303 that are sequentially stacked up and down. The transverse ends of the roofing composite panel 3 are respectively formed into a splicing male edge portion 304 and a splicing female edge portion 305. The part of the metal plate 303 located in the splicing female edge portion 305 is formed into a female edge overlapping portion 3031 that extends out of the edge of the thermal insulation layer 302. The splicing male edge portion 304 of one of the two mutually spliced roofing composite panels 3 overlaps on the female edge overlapping portion 3031 of the other. The first connecting component 1 is used to connect the female edge overlapping portion 3031 and the roof purlin 5, so as to lock the splicing female edge portion 305 of the roofing composite panel 3 on the roof purlin 5. The second connecting component 2 is used to sequentially connect the splicing male edge portion 304 and the female edge overlapping portion 3031, so as to lock the two roofing composite panels 3 to each other on the roof purlin 5. When the second connecting component 2 connects the splicing male edge portion 304, it can sequentially connect the waterproof coiled material 301, the thermal insulation layer 302, and the metal plate 303 located in the splicing male edge portion 304, so as to lock the waterproof coiled material 301 on the thermal insulation layer 302.

[0045] It can be seen that in the roofing system of this exemplary embodiment, for two mutually spliced roofing composite panels 3, by overlapping the splicing male edge portion 304 of one of them on the female edge overlapping portion 3031 of the other, using the first connecting component 1 to connect the female edge overlapping portion 3031 and the roof purlin 5, and using the second connecting component 2 to sequentially connect the splicing male edge portion 304 and the female edge overlapping portion 3031, the two mutually spliced roofing composite panels 3 can be firmly locked together. In this way, for the roofing system spliced by a plurality of roofing composite panels 3, the overall structural strength and structural stability of the roofing system can be greatly improved. In addition, in the state where the second connecting component 2 connects the splicing male edge portion 304, the waterproof coiled material 301 located on the top layer of the splicing male edge portion 304 can be pressed on the thermal insulation layer 302, thereby effectively improving the anti-peeling ability of the waterproof coiled material 301, and the wind resistance of the roofing composite panel 3 and even the entire roofing system is improved accordingly, effectively avoiding damage to the roof due to the influence of wind force.

[0046] During the construction of the roofing system, when using the second connecting component 2 to sequentially connect the splicing male edge portion 304 and the female edge overlapping portion 3031, the second connecting component 2 can connect the second thermal insulation material layer 3022 in the splicing male edge portion 304. Since a relatively rigid material such as polyurethane can be used as the second thermal insulation material layer 3022, the second thermal insulation material layer 3022 can provide sufficient fixing support force and enhance the connection strength.

[0047] In an optional or preferred embodiment, asFigure 3 and Figure 4 As shown, the female side lapping portion 3031 is formed as a female side groove portion, and the splicing male side portion 304 is formed as a male side protruding portion. In the two roof composite panels 3 that are spliced with each other, the male side protruding portion is embedded in the female side groove portion, so that the two roof composite panels 3 can be limited to each other, effectively avoiding the deviation of the unfixed roof composite panel 3 in the case where the second connecting component 2 is not passed through and connected.

[0048] Furthermore, referring to Figure 1 , the part of the metal plate 303 located at the splicing male side portion 304 can extend to form an upturned portion 3032. The upturned portion 3032 abuts against the side wall of the thermal insulation layer 302, so that a rigid edge wrapping formed by the metal plate 303 is formed at the bottom of the splicing male side portion 304. Under the partial wrapping of the metal plate 303, the thermal insulation layer 302 can be effectively protected to a certain extent, and the structural strength of the roof composite panel 3 is effectively enhanced.

[0049] In an alternative or preferred embodiment, as Figure 3 shown, the roof system includes a splicing joint 4. The splicing joint 4 is defined by the bottom wall of the male side protruding portion embedded in the female side groove portion and the top wall of the female side groove portion. The first connecting component 1 includes a first screw. When the first screw passes through the female side groove portion and the roof purlin 5, the screw head of the first screw is located in the splicing joint 4. In Figure 3 the shown embodiment, the cross-sections of the male side protruding portion and the female side groove portion are both conical. Among them, the outward expansion angle of the male side protruding portion is greater than the outward expansion angle of the female side groove portion, so that when the male side protruding portion is embedded in the female side groove portion, the bottom wall of the male side protruding portion is spaced from the top wall of the female side groove portion, avoiding damage caused by the bottom wall of the male side protruding portion pressing on the screw head of the first screw.

[0050] In an alternative or preferred embodiment, referring to Figure 4 , the second connecting component 2 includes a second screw and a screw gasket. The second screw is used to sequentially pass through the screw gasket, the splicing male side portion 304 and the female side lapping portion 3031. In this embodiment, a C-shaped gasket can be used as the screw gasket. By using the second screw in cooperation with the C-shaped gasket, the part of the waterproof coiled material 301 located at the splicing male side portion 304 can be effectively pressed against the thermal insulation layer 302, so that it firmly adheres to the thermal insulation layer 302, thus avoiding the peeling of the waterproof coiled material 301 under the influence of wind force and greatly enhancing the wind resistance of the roof composite panel 3. It should be noted that the connecting positions of the second connecting component 2 and the first connecting component 1 are staggered from each other to avoid damaging the connecting holes of each other.

[0051] In other embodiments, after the second threading component 2 is used to thread and splice the male edge portion 304 and the female edge overlapping portion 3031, the roof purlin 5 can be continuously threaded, so that the second threading component 2 simultaneously threads and fixes the two roof composite panels 3 and the roof purlin 5, thereby further enhancing the stability of the two mutually spliced roof composite panels 3.

[0052] Further, referring to Figures 2 to 4 , the part of the waterproof coiled material 301 located at the spliced female edge portion 305 is formed into a coiled material overlapping portion 3011 extending from the edge of the thermal insulation layer 302. Among the two mutually spliced roof composite panels 3, the coiled material overlapping portion 3011 of one roof composite panel 3 covers the top of the second threading component 2 and is welded to the top surface of the waterproof coiled material 301 of the other roof composite panel 3, so that the coiled material overlapping portion 3011 can seal the joint seam of the two roof composite panels 3, especially can completely seal the wound formed after the second threading component 2 threads and splices the male edge portion 304. In this way, the overall sealing performance of the roof system can be ensured, making it achieve excellent waterproof and heat insulation effects.
