Description

Technical Field

[0001] The present disclosure relates to the technical field of waterproof coiled materials, and particularly to a self-adhesive super weather-resistant and super light-resistant composite waterproof coiled material and a construction structure for a light-transmitting roof. Background Art

[0002] The combined use of a metal roof and a daylighting tile is a relatively common roof construction structure at present. During use, due to the different shrinkage ratios of the daylighting tile and the metal plate in high and low temperature environments, the daylighting tile is prone to deformation, resulting in water leakage at the connection between the daylighting tile and the metal plate.

[0003] To solve the above water leakage problem, in practice, color steel plates are usually directly covered or waterproof glue is directly applied, so as to achieve a certain waterproof effect. However, both of the above two methods have the problem of poor daylighting inside the house.

[0004] For this reason, some new types of transparent waterproof glue have emerged on the market. For example, Chinese Patent Document No. CN115975551A discloses a transparent butyl hot melt adhesive and a preparation method thereof; another example is Chinese Patent Document No. CN112280498A which discloses a transparent butyl glue for photovoltaic use, which can effectively improve the light transmittance of traditional waterproof glue to solve the problem of poor daylighting inside the house.

[0005] However, in actual applications, since the transparent waterproof glue is directly exposed on the outer surface of the roof, the transparent waterproof glue is easily corroded by the outside air and ultraviolet rays, thus affecting its service life. At this time, many scholars also believe that the amount of anti-corrosion material used in the transparent waterproof glue can be increased, that is, the amount of antioxidant or anti-ultraviolet agent used can be increased. However, increasing a large amount of anti-corrosion material will affect the light transmittance of the transparent waterproof glue and cannot meet the application requirements of high daylighting in outdoor roofs. Utility Model Content

[0006] The purpose of the present disclosure is to overcome the deficiencies in the prior art, and to provide a self-adhesive super weather-resistant and super light-resistant composite waterproof coiled material and a construction structure for a light-transmitting roof that have super weather resistance, super light resistance and good initial adhesion performance without excessively increasing the amount of antioxidant or anti-ultraviolet agent, and are simple to construct, so as to better be applicable to the long-term application of roof construction structures with high daylighting requirements outdoors.

[0007] The purpose of the present disclosure is achieved through the following technical solutions:

[0008] A self-adhesive super weather-resistant and super light-resistant composite waterproof coiled material includes a release film layer, a butyl glue layer and a fluorocarbon film layer which are sequentially stacked.

[0009] The butyl glue layer is a transparent butyl glue layer, and the fluorocarbon film layer is a PVF layer.

[0010] In one embodiment, a plurality of scattering bumps are formed on one side of the PVF layer facing the transparent butyl rubber layer, and the scattering bumps are arranged at intervals.

[0011] A plurality of positioning grooves are correspondingly formed on one side of the transparent butyl rubber layer facing the PVF layer, and each of the scattering bumps is arranged in one-to-one correspondence with each of the positioning grooves.

[0012] In one embodiment, each of the scattering bumps is arranged in a matrix distribution.

[0013] In one embodiment, the height of the scattering bumps is 1 μm to 50 μm; and / or,

[0014] the diameter of the scattering bumps is 1 μm to 50 μm; and / or,

[0015] the distance between each of the scattering bumps is 50 μm to 1000 μm.

[0016] In one embodiment, each of the scattering bumps and the PVF layer are of an integrally formed structure.

[0017] In one embodiment, the scattering bumps are hemispherical.

[0018] In one embodiment, the thickness of the PVF layer is 80 μm to 100 μm.

[0019] In one embodiment, the thickness of the transparent butyl rubber layer is 600 μm to 900 μm.

[0020] In one embodiment, the thickness of the release film layer is 30 μm to 50 μm.

[0021] A light-transmitting roofing construction structure includes the self-adhesive ultra-weather-resistant and ultra-light-resistant composite waterproof coiled material described in any of the above embodiments.

[0022] Compared with the prior art, the present disclosure has at least the following advantages:

[0023] Since the self-adhesive super weather-resistant and super light-resistant composite waterproof coil includes a release film layer, a butyl rubber layer, and a fluorocarbon film layer that are sequentially stacked; and the butyl rubber layer is a transparent butyl rubber layer and the fluorocarbon film layer is a PVF layer. During use, the construction worker first peels off the release film layer to expose the transparent butyl rubber layer, and then adheres the transparent butyl rubber layer to the roof, realizing the connection and fixation of the self-adhesive super weather-resistant and super light-resistant composite waterproof coil to the roof. In this way, using the PVF layer as the protective layer of the transparent butyl rubber layer enables the PVF layer to effectively isolate most of the ultraviolet rays and moisture from the outside world, thus effectively preventing the outside air and ultraviolet rays from entering the transparent butyl rubber layer, and further providing a good protective effect for the transparent butyl rubber layer, effectively avoiding the damage of most of the ultraviolet rays from the outside world to the amorphous polyolefin elastomer. Also, due to the high light transmittance and light weight characteristics of the PVF layer itself, the added PVF layer does not affect the light transmittance of the self-adhesive super weather-resistant and super light-resistant composite waterproof coil, enabling the self-adhesive super weather-resistant and super light-resistant composite waterproof coil of the present disclosure to have super weather resistance, super light resistance, and good initial adhesion performance without excessive use of antioxidants or ultraviolet agents, and the construction is simple, so as to be better applicable to the long-term application of the roof construction structure with high lighting requirements outdoors.

Detailed implementation mode

[0031] To facilitate the understanding of the present disclosure, the present disclosure will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present disclosure are shown in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure content of the present disclosure more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only embodiments.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present disclosure belongs. The terms used in the description of the present disclosure in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0034] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with reference to specific embodiments:

[0035] As Figures 1 to 3 shown, the self-adhesive super weather-resistant and super light-resistant composite waterproof coiled material 10 of an embodiment includes a release film layer 100, a butyl rubber layer and a fluorocarbon film layer stacked in sequence. The butyl rubber layer is a transparent butyl rubber layer 200, and the fluorocarbon film layer is a PVF layer 300.

[0036] It can be understood that since the self-adhesive super weather-resistant and super light-resistant composite waterproof coil 10 includes a release film layer 100, a butyl rubber layer, and a fluorocarbon film layer that are sequentially stacked; and the butyl rubber layer is a transparent butyl rubber layer 200, and the fluorocarbon film layer is a PVF layer 300. During use, the construction personnel first peel off the release film layer 100 to expose the transparent butyl rubber layer 200, and then adhere the transparent butyl rubber layer 200 to the roof, realizing the connection and fixation of the self-adhesive super weather-resistant and super light-resistant composite waterproof coil 10 to the roof. In this way, using the PVF layer 300 as a protective layer for the transparent butyl rubber layer 200 enables the PVF layer 300 to effectively isolate most of the ultraviolet rays and moisture from the outside world, thereby effectively preventing the outside air and ultraviolet rays from entering the transparent butyl rubber layer 200, and further providing a good protective effect for the transparent butyl rubber layer 200, effectively avoiding the damage of most of the ultraviolet rays from the outside world to the amorphous polyolefin elastomer. Also, due to the high light transmittance and light weight characteristics of the PVF layer 300 itself, the added PVF layer 300 does not affect the light transmittance of the self-adhesive super weather-resistant and super light-resistant composite waterproof coil 10, enabling the self-adhesive super weather-resistant and super light-resistant composite waterproof coil 10 of the present disclosure to have super weather resistance, super light resistance, and good initial adhesion performance without excessive use of antioxidants or ultraviolet resistant agents, and the construction is simple, so as to be better applicable to the long-term application of the roof construction structure with high daylighting requirements outdoors.

[0037] It should be noted that the transparent butyl rubber layer 200 and the PVF layer 300 of the present disclosure are both existing technologies, and the present disclosure only protects the connection relationship between the release film layer 100, the butyl rubber layer, and the fluorocarbon film layer.

[0038] As Figure 4 and Figure 5 shown, in one embodiment, a plurality of spaced-apart scattering bumps 310 are formed on the surface of the PVF layer 300 facing the transparent butyl rubber layer 200, and a plurality of positioning grooves 210 are correspondingly formed on the surface of the transparent butyl rubber layer 200 facing the PVF layer 300, and each of the scattering bumps 310 is arranged in one-to-one correspondence with each of the positioning grooves 210.

[0039] It can be understood that since the added plurality of spaced-apart scattering bumps 310 not only increase the light emission area from the PVF layer 300, realizing the relatively comprehensive emission of light in the PVF layer 300, which is beneficial to the scattering of light in the transparent butyl rubber layer 200, thereby increasing the light emission area of the transparent butyl rubber layer 200, and further increasing the light scattering area of the self-adhesive super weather-resistant and super light-resistant composite waterproof coil 10, and further increasing the indoor daylighting area; at the same time, each of the scattering bumps 310 is arranged in one-to-one correspondence with each of the positioning grooves 210, thereby improving the connection firmness between the transparent butyl rubber layer 200 and the PVF layer 300, effectively avoiding the problem that the self-adhesive super weather-resistant and super light-resistant composite waterproof coil 10 is prone to falling off in the relatively harsh outdoor environment of wind and rain.

[0040] As Figure 4 and Figure 5 shown, in one embodiment, a recessed groove 320 is formed between every two adjacent scattering bumps 310, and a plurality of formed inserts 220 are formed in the transparent butyl rubber layer 200. Each of the formed inserts 220 is arranged in one-to-one correspondence with each of the recessed grooves 320 to realize the two-way fitting connection between the PVF layer 300 and the transparent butyl rubber layer 200, and better improve the connection firmness between the PVF layer 300 and the transparent butyl rubber layer 200.

[0041] In one embodiment, the scattering bumps 310 are arranged in a matrix. In this way, on the premise of ensuring that the self-adhesive super weather and light resistant composite waterproof coil 10 has a relatively large emission area, it is ensured that the self-adhesive super weather and light resistant composite waterproof coil 10 has a relatively large lighting area and good lighting effect, and also better ensures the connection firmness of the self-adhesive super weather and light resistant composite waterproof coil 10 in a relatively harsh outdoor environment of windy and rainy weather.

[0042] It can be understood that although the added plurality of scattering bumps 310 can improve the lighting effect and connection firmness of the self-adhesive super weather and light resistant composite waterproof coil 10, they will affect the fluidity of the butyl colloid on the coating surface of the PVF layer 300. Therefore, in one embodiment, the height of the scattering bumps 310 is 1 μm to 50 μm; especially in combination with the diameter of the scattering bumps 310 being 1 μm to 50 μm and the spacing between the scattering bumps 310 being 50 μm to 1000 μm; the height of the plurality of scattering bumps 310 on the coating surface of the PVF layer 300 is appropriate, which is beneficial to the flow of the butyl colloid on each scattering bump 310, and also improves the lighting effect and connection firmness of the self-adhesive super weather and light resistant composite waterproof coil 10.

[0043] In one embodiment, each of the scattering bumps 310 and the PVF layer 300 are of an integrally formed structure to ensure the connection firmness between the PVF layer 300 and the plurality of scattering bumps 310, thereby improving the service life of the self-adhesive super weather and light resistant composite waterproof coil 10.

[0044] In one embodiment, the scattering bumps 310 are hemispherical. It can be understood that since the hemispherical scattering bumps 310 can scatter light better, the light emission area of the transparent butyl rubber layer 200 is better improved, and the hemispherical scattering bumps 310 are more conducive to the flow of the transparent butyl colloid, which is beneficial to the formation of a uniform transparent butyl rubber layer 200.

[0045] In one embodiment, the thickness of the PVF layer 300 is 80 μm to 100 μm to ensure that the thickness of the PVF layer 300 is more appropriate. On the premise that the PVF layer 300 has good light transmittance, it is also ensured that the PVF layer 300 can well isolate external ultraviolet light and moisture, thereby achieving a more comprehensive protection effect on the transparent butyl rubber layer 200, effectively preventing external ultraviolet light and moisture from entering the transparent butyl rubber layer 200 and affecting the service life of the self-adhesive super weather-resistant and super light-resistant composite waterproof membrane 10; it also ensures the lightness of the PVF layer 300, which is conducive to the installation and transportation of outdoor roofs with high heights.

[0046] In one embodiment, the transparent butyl rubber layer 200 has a thickness of 600 μm to 900 μm.

[0047] It can be understood that if the thickness of the transparent butyl rubber layer 200 is less than 600μm, it cannot be ensured that the transparent butyl rubber layer 200 can provide a firm connection for the PVF layer 300; if the thickness of the transparent butyl rubber layer 200 is greater than 900μm, the overall thickness of the self-adhesive super weather-resistant and super light-resistant composite waterproof membrane 10 is thicker, resulting in the overall weight of the self-adhesive super weather-resistant and super light-resistant composite waterproof membrane 10 becoming higher. For some outdoor roofs with higher heights, if the weight of the self-adhesive super weather-resistant and super light-resistant composite waterproof membrane 10 is heavier, it is not conducive to the installation and transportation of outdoor roofs with higher heights; thereby causing the problem of low construction efficiency; and the thickened self-adhesive super weather-resistant and super light-resistant composite waterproof membrane 10 will also affect the light transmittance of the self-adhesive super weather-resistant and super light-resistant composite waterproof membrane 10. Therefore, in the present disclosure, by controlling the thickness of the transparent butyl rubber layer 200 to be 600μm to 900μm, the thickness of the butyl rubber layer is made more appropriate. In this way, on the premise that the transparent butyl rubber layer 200 can provide a firm connection between the roof and the PVF layer 300, it is also ensured that a lightweight self-adhesive super weather-resistant and super light-resistant composite waterproof membrane 10 is obtained, which is conducive to construction and installation; especially when the thickness of the transparent butyl rubber layer 200 is less than 600μm, the light transmittance and lightness of the self-adhesive super weather-resistant and super light-resistant composite waterproof membrane 10 are better guaranteed, so that it is better suitable for the application of roof construction structures with high outdoor height and light intensity.

[0048] In one embodiment, the thickness of the release film layer 100 is 30 μm to 50 μm to ensure that the thickness of the release film layer 100 is appropriate, effectively avoiding the self-adhesive super weather-resistant and super light-resistant composite waterproof membrane 10 becoming heavier due to the thickness of the release film layer 100, thereby affecting installation and transportation.

[0049] The present disclosure also provides a light-transmitting roofing construction structure, including the self-adhesive super weather-resistant and super light-resistant composite waterproofing membrane 10 described in any of the above embodiments. The above light-transmitting roofing construction structure, due to the adoption of the self-adhesive super weather-resistant and super light-resistant composite waterproofing membrane 10 of the present disclosure, is not only convenient for construction and installation, but also improves the weather resistance, light resistance and adhesiveness of the light-transmitting roofing construction structure, so as to better apply to the long-term application of roofing construction structures with high daylighting requirements outdoors, and can achieve the effects of light transmission, waterproofing and anti-corrosion with the same service life as the building roof.

[0050] In one embodiment, the light-transmitting roofing construction structure further includes a roofing body, and the transparent butyl rubber layer 200 of the self-adhesive super weather-resistant and super light-resistant composite waterproofing membrane 10 is attached to the outer surface of the roofing body, realizing the firm connection with the roofing body.

[0051] In a preferred embodiment, the roofing body is a metal roofing body. The metal roofing body includes a first metal roofing component and a second metal roofing component, and a light-transmitting gap is formed between the first metal roofing component and the second metal roofing component. The self-adhesive super weather-resistant and super light-resistant composite waterproofing membrane covers the outer surfaces of the first metal roofing component and the second metal roofing component, so that the self-adhesive super weather-resistant and super light-resistant composite waterproofing membrane 10 is located in the light-transmitting gap, so as to achieve the high light transmission, waterproofing and anti-corrosion effects of the self-adhesive super weather-resistant and super light-resistant composite waterproofing membrane 10 on the metal roofing body, thereby ensuring the long-term light transmission requirements of the light-transmitting roofing construction structure.

[0052] Compared with the prior art, the present disclosure has at least the following advantages:

[0053] Since the self-adhesive super weather-resistant and super light-resistant composite waterproofing membrane includes a release film layer, a butyl rubber layer and a fluorocarbon film layer which are sequentially laminated; and the butyl rubber layer is a transparent butyl rubber layer and the fluorocarbon film layer is a PVF layer. During use, the construction worker first peels off the release film layer to expose the transparent butyl rubber layer, and then adheres the transparent butyl rubber layer to the roof, realizing the connection and fixation of the self-adhesive super weather-resistant and super light-resistant composite waterproofing membrane and the roof. In this way, the PVF layer is used as the protective layer of the transparent butyl rubber layer, so that the PVF layer can effectively isolate most of the ultraviolet rays and moisture from the outside world, thereby effectively preventing the outside air and ultraviolet rays from entering the transparent butyl rubber layer, and further can provide a good protective effect for the transparent butyl rubber layer, effectively avoiding the damage of most of the ultraviolet rays from the outside world to the amorphous polyolefin elastomer. Also, due to the high light transmission and light weight characteristics of the PVF layer itself, the added PVF layer does not affect the light transmission of the self-adhesive super weather-resistant and super light-resistant composite waterproofing membrane, so that the self-adhesive super weather-resistant and super light-resistant composite waterproofing membrane of the present disclosure has super weather resistance, super light resistance and good initial adhesion performance without using too much antioxidant or anti-ultraviolet agent, and the construction is simple, so as to better apply to the long-term application of roofing construction structures with high daylighting requirements outdoors.

[0054] The above-described embodiments merely represent several implementation manners of the present disclosure. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the disclosed patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several variations and improvements can still be made, and these all fall within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
