In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0024] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0025] In order to solve the problems in the prior art, the embodiment of the present application provides an anti-ultraviolet waterproof board. The anti-ultraviolet waterproof board provided by the embodiment of the present application is first introduced below.

[0026] Figure 1 The structure diagram of the anti-ultraviolet waterproof board provided by one embodiment of the present application is shown. Figure 1 As shown, the anti-ultraviolet waterproof board comprises: a waterproof board 1, an aerogel layer 2, the aerogel layer 2 is arranged on a first side of the waterproof board 1 along its own thickness direction, the aerogel layer 2 and the waterproof board 1 are combined into an integrated structural board, the integrated structural board comprises a plurality of profiled portions 3 extending along a first direction L and spaced apart in a second direction W by connecting portions 5, the profiled portions 3 are formed by protruding from the first surface toward the second surface of the integrated structural board.

[0027] The anti-ultraviolet waterproof board in the embodiment of the present application provides an aerogel layer on the first side of the waterproof board along its thickness direction to wrap the waterproof board inside, so that the anti-ultraviolet waterproof board has an anti-ultraviolet structural layer, which can effectively protect the waterproof board and delay the aging rate of the waterproof membrane of the waterproof board under long-term ultraviolet radiation, thereby extending the service life of the waterproof membrane and even the anti-ultraviolet waterproof board.

[0028] In the embodiment of the present application, the integral structural plate is provided with profiled portions 3 on two opposite sides along the second direction W. Of the two anti-ultraviolet waterproof boards disposed adjacent to each other along the second direction W, the profiled portion 3 of one of the two boards disposed adjacent to each other along the second direction W is engaged with the profiled portion 3 of the other board, so that the two anti-ultraviolet waterproof boards disposed adjacent to each other along the second direction W are overlapped.

[0029] In some embodiments of the present application, the waterproof board 1 includes a metal layer 10 and a waterproof layer 11, the waterproof layer 11 is arranged on one side of the metal layer 10, and the aerogel layer 2 is arranged on the side of the waterproof layer 11 away from the metal layer 10. Figure 1 and 2 As shown, the metal layer 10, the waterproof layer 11 and the aerogel layer 2 are stacked in sequence from bottom to top to form the roof anti-ultraviolet waterproof board. The aerogel layer 2 contains the waterproof layer 11 and the metal layer 10 on the inner side to prevent the waterproof layer 11 from directly contacting the ultraviolet rays in the external environment, thereby reducing the aging rate of the waterproof layer 11 and preventing the waterproof layer 11 of the anti-ultraviolet waterproof board from aging under long-term ultraviolet rays, thereby preventing the performance of the waterproof board composed of the metal layer 10 and the waterproof layer 11 from being affected.

[0030] In the embodiment of the present application, the aerogel layer 2 can block rainwater from the outside. Due to the anti-ultraviolet and waterproof functions of the aerogel itself, the life and durability of the waterproof board are improved. At the same time, the aerogel layer does not absorb water, which avoids the aggregation of water molecules, and solves the problem that the slope roll felt has a high water absorption rate and the thermal conductivity of water molecules affects thermal insulation. When scattered and fine rainwater infiltrates from the top of the aerogel layer to the waterproof layer, the waterproof layer isolates the infiltrating rainwater to prevent the rainwater from infiltrating into the insulation layer under the waterproof board and taking away heat. The insulation layer with low thermal conductivity avoids the temperature loss of the factory building below the insulation layer, and has a heat preservation effect.

[0031] In an embodiment of the present application, the aerogel layer 2 is formed by coating a layer of aerogel coating on the first side of the waterproof board 1, that is, the upper surface of the waterproof board 1, and the aerogel coating and the waterproof board are completely formed into a whole through high temperature and high pressure, so that the waterproof board has its own UV protection function, thereby obtaining an anti-UV waterproof board.

[0032] In one embodiment of the present application, the aerogel coating is first produced as an aerogel roll felt, and then a layer of POE film is added between the aerogel roll felt and the waterproof board 1. The aerogel roll felt and the waterproof board are integrated at 130°C to 190°C by processing equipment in the factory to obtain an anti-ultraviolet waterproof board. The entire anti-ultraviolet waterproof board is then pressed into a roof panel type or a wall panel type by a tile press.

[0033] In some embodiments of the present application, the waterproof layer 11 is made of highly weather-resistant thermoplastic polyolefin TPO waterproofing membrane or polyvinyl chloride waterproofing membrane. The thermoplastic polyolefin TPO waterproofing membrane and polyvinyl chloride waterproofing membrane can be obtained through commercial channels. The metal layer 10 is made of stainless steel or aluminum alloy steel or aluminum plate.

[0034] In the embodiment of the present application, the first surface of the anti-ultraviolet waterproof board is the surface of the metal layer 10 facing away from the waterproof layer 11 , and the second surface is the surface of the aerogel layer 2 facing away from the waterproof layer 11 .

[0035] In some embodiments of the present application, Figure 2 As shown, an anti-ultraviolet particle layer 4 is provided on the surface of the aerogel layer 2 facing away from the waterproof board 1 .

[0036] In some embodiments of the present application, Figure 2 As shown, the anti-ultraviolet particle layer 4 includes anti-ultraviolet particles 40 distributed on the surface of the aerogel layer 2 away from the waterproof board 1. In the actual manufactured product, there is no obvious structural interface between the anti-ultraviolet particle layer 4 and the aerogel layer 2. For ease of understanding, Figure 2 The structure of the anti-ultraviolet particle layer 4 is shown in FIG. 4 , and the anti-ultraviolet particle layer 4 is represented as a different structural layer having a clear interface with the aerogel layer 2 .

[0037] In some embodiments of the present application, the particle size of the anti-ultraviolet particles 40 is 55nm-290nm and 400nm-1000nm, and the distance between the anti-ultraviolet particles 40 is 1μm-200μm. Exemplarily, the particle size of the anti-ultraviolet particles is 60, 70, 75, 80, 90, 100, 110, 120, 125, 130, 140, 150, 160, 175, 180, 190, 200, 220, 230, 240, 255, 260, 275, 280nm, and the particle size of the anti-ultraviolet particles is 410, 425, 430, 440, 450, 480, 500, 520, 550, 575, 590, 600, 650, 680, 700, 720, 750, 760, 780, 800, 820, 850, 900, 930, 980nm, the spacing of the UV-resistant particles is 1, 3, 4, 6, 9, 10, 12, 20, 25, 30, 40, 45, 50, 55, 60, 70, 75, 80, 90, 100, 110, 120, 125, 130, 140, 150, 160, 175, 180, 190, 200μm.

[0038] In some embodiments, the anti-ultraviolet particles 40 with a particle size of 55 nm to 290 nm account for 55 wt.% to 90 wt.%, and the anti-ultraviolet particles 40 with a particle size of 400 nm to 1000 nm account for 10 wt.% to 45 wt.%.

[0039] In the embodiment of the present application, the anti-ultraviolet particles 40 can be formed by spraying aerogel on the aerogel layer 2, and the anti-ultraviolet particles 40 distributed on the surface of the aerogel layer 2 away from the waterproof layer form the anti-ultraviolet particle layer 4, forming an uneven diffuse reflection surface, which diffusely reflects the ultraviolet light to the outside of the aerogel layer 2 to protect the waterproof board. The aerogel coating can be an aerogel coating with a product model of YTAC-001-A purchased from Hunan Yantuo New Materials Technology Co., Ltd.

[0040] In some embodiments of the present application, Figure 3 and Figure 4 As shown, grooves 41 distributed in an array are provided on one side of the aerogel layer 2 away from the waterproof board 1, and anti-ultraviolet particles 40 are filled in the grooves 41 to form an anti-ultraviolet particle layer 4. It can be understood that the depth of the grooves 41 can partially or completely penetrate the aerogel layer 2, and then the anti-ultraviolet particles 40 are filled in the grooves 41. The anti-ultraviolet particles 40 can use their own surface to reflect or refract ultraviolet rays, and at the same time, the anti-ultraviolet particles 40 in the grooves 41 can also block ultraviolet rays.

[0041] In some embodiments of the present application, the grooves 41 are arranged at intervals of ≤1 mm. It is understandable that the grooves 41 are arranged at intervals of 50 μm, 100 μm, 200 μm, 300 μm, 500 μm, 600 μm, 750 μm, 800 μm, 900 μm, and 1 mm on the upper surface of the aerogel layer 2, that is, on the side of the aerogel layer 2 facing away from the waterproof layer 11.

[0042] In the anti-ultraviolet waterproof board of the embodiment of the present application, the aerogel layer can effectively block ultraviolet rays from entering the waterproof layer of the anti-ultraviolet waterproof board, thereby preventing ultraviolet rays from damaging the waterproof layer. In combination with the anti-ultraviolet particle layer of the anti-ultraviolet waterproof board, the ultraviolet rays are scattered or diffusely reflected, further reducing the amount of ultraviolet rays incident on the waterproof board, reducing the aging rate of the waterproof layer, and increasing the service life of the waterproof layer and even the internal steel plate, thereby increasing the service life of the anti-ultraviolet waterproof board. After the anti-ultraviolet waterproof board is applied to the roof system, the waterproof life of the entire roof system is increased.

[0043] In some embodiments of the present application, the side of the aerogel layer 2 facing away from the waterproof board 1 is provided with array-distributed concave holes 42, the pore size of the concave holes 42 is 30nm to 300nm, and the density of the concave holes 42 in the aerogel layer 2 is 1000 to 10000 / cm2 The recessed holes 42 provided on the aerogel layer 2 can block ultraviolet rays outside the aerogel layer, thereby preventing the ultraviolet rays from directly irradiating the waterproof layer 11 and causing aging of the waterproof layer 11. For example, the pore size of the concave holes 42 is 30, 40, 45, 50, 60, 70, 80, 95, 100, 110, 130, 150, 160, 175, 180, 190, 200, 210, 220, 230, 240, 255, 260, 270, 280, 290 nm, and the density distribution of the concave holes 42 is 1200, 1500, 1560, 1600, 1650, 1750, 1800, 2000, 2200, 2400, 2500, 3000, 3500, 3600, 4200, 4500, 4800, 5000, 6000, 7000, 7500, 8000, 9000, 9100, 9600 pcs / cm 2 The above-mentioned aperture (i.e., 15% to 90% of the wavelength of ultraviolet light) and distribution density of the concave holes can effectively block ultraviolet light outside the concave holes, preventing direct irradiation to the waterproof layer 11 and causing aging of the waterproof layer 11. The aperture of the concave holes 42 can be 20%, 25%, 28%, or 30% of the wavelength of ultraviolet light.

[0044] In some embodiments of the present application, the bottom surface of the aerogel layer 2 forms an angle α with the central axis of the concave hole 42, satisfying 10°≤α<90°, so that after the anti-ultraviolet waterproof board is installed on the roof or side wall, water can not easily penetrate through the concave hole, and can be discharged through the concave hole 42. Exemplarily, the bottom surface of the aerogel layer 2 forms an angle α with the central axis M of the concave hole 42, and the value of α is 15°, 20°, 25°, 30°, 45°, 50°, 60°, 63°, 75°, 80°, 85°. Among them, the angle α can be designed according to the setting inclination angle of the anti-ultraviolet waterproof board.

[0045] In some embodiments, the depth of the concave hole 42 partially extends into the interior of the aerogel layer 2, or completely penetrates the waterproof layer 11. Exemplarily, for a flat anti-ultraviolet waterproof board, the depth of the concave hole 42 partially extends into the aerogel layer 2, but does not penetrate the waterproof layer 11. Optionally, in some embodiments, the central axis M of the concave hole 42 is bent or arc-shaped in the concave hole, that is, the concave hole is in a bent hole shape, or an arc-shaped hole, so as to block ultraviolet rays outside the concave hole by using the aperture and shape of the concave hole.

[0046] like Figure 5 As shown, when the anti-ultraviolet waterproof sheet is applied to the roof, the angle α formed between the central axis M of the concave hole 42 of the aerogel layer 2 of the anti-ultraviolet waterproof sheet and the bottom surface of the aerogel layer is 35°.

[0047] In some embodiments of the present application, the open end of the concave hole 42 on the outer side of the aerogel layer 2 may be covered with a tough adhesive film to form a closed concave hole 42 .

[0048] In some embodiments of the present application, the groove 41 or the concave hole 42 may be partially or completely filled with zinc or zinc alloy powder, metal oxide ceramic powder, or amorphous silicon dioxide powder.

[0049] In some embodiments of the present application, the cross-sectional opening of the groove 41 or the concave hole 42 is gradually reduced from the aerogel layer 2 to the direction away from the waterproof layer 11. For example, the cross-sectional opening may be triangular, trumpet-shaped, trapezoidal, semicircular, or semi-elliptical. Figure 6 As shown, the cross-sectional opening of the concave hole 42 is in a gradually decreasing triangular shape. After the anti-ultraviolet particles 40 are filled therein, the anti-ultraviolet particles 40 can be used to block ultraviolet rays from entering the waterproof layer, and the anti-ultraviolet particles 40 can reflect ultraviolet rays through the plane formed by the aerogel layer 2 in the triangular concave hole 42 away from the waterproof layer 11, or the curved surface formed by the concave holes 42 of other shapes, thereby further playing an anti-ultraviolet role.
