Abstract
Description
Technical Field
[0001] The utility model relates to the field of building waterproof coiled materials, in particular to a bendable weather-resistant building waterproof coiled material. Background Art
[0002] Waterproof membrane is mainly used for building walls, roofs, tunnels, roads, landfills, etc. It is a kind of flexible building material product that can be rolled into a roll to resist the leakage of external rainwater and groundwater. As a leakage-free connection between the engineering foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project. Fluorinated butyl waterproof membrane is a self-adhesive membrane, which has good weather resistance and a long service life.
[0003] However, when the roll material is laid, the width of each laying is certain, so there will be a certain gap between adjacent roll materials. After the entire paving is completed, in order to improve the overall waterproof performance, the construction workers need to lay another layer between adjacent roll materials. The sticky layer of the roll material sticks to the protective layer on the surface, affecting the waterproof effect. Utility Model Content
[0004] The main purpose of the utility model is to provide a bendable weather-resistant building waterproofing membrane, which can effectively solve the problems in the background technology.
[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a flexible weather-resistant building waterproof membrane, including a first adhesive layer and a second adhesive layer, the first adhesive layer is compounded on the upper surface of the second adhesive layer, an isolation layer is arranged between the first adhesive layer and the second adhesive layer near the edge, and a protective layer is compounded on the upper surface of the first adhesive layer.
[0006] The isolation layer comprises a support layer, the upper surface of the support layer is compounded with a high-strength adhesive layer, and the lower surface of the support layer is compounded with a low-strength adhesive layer.
[0007] The edge of the isolation layer protrudes from the edges of the first adhesive layer, the second adhesive layer and the protective layer.
[0008] The end of the isolation layer is tilted close to the protection layer.
[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] In the utility model, an isolation layer, a first adhesive layer and a second adhesive layer are provided. When the first row is laid, the first adhesive layer and the second adhesive layer are torn apart along the position of the isolation layer, and a portion of the coiled material to be laid again is pressed onto the upper surface of the second adhesive layer. At this time, the connection between the two second adhesive layers has a very good waterproof effect at the connection position because the two have great viscosity. When the row position is laid, the first adhesive layer is pressed and adhered to the surface of the protective layer. At this time, a secondary seal is performed to further improve the waterproof performance.
[0011] In the utility model, a high-strength adhesive layer and a low-strength adhesive layer are provided, and the viscosity of the high-strength adhesive layer is greater than that of the low-strength adhesive layer. Therefore, the second adhesive layer is easier to tear off from the surface of the isolation layer. When the second row of coils is laid, it is necessary to ensure that the isolation layer is adhered to the surface of the first adhesive layer to prevent it from sticking to the wrong position during the laying process.

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0016] like Figure 1-2 As shown, a flexible weather-resistant building waterproof membrane comprises a first adhesive layer 1 and a second adhesive layer 2, both of which are fluorinated butyl adhesive and are an integrally formed structure, wherein the first adhesive layer 1 is compounded on the upper surface of the second adhesive layer 2, an isolation layer 3 is arranged between the first adhesive layer 1 and the second adhesive layer 2 near the edge, the isolation layer 3 has weak adhesion to the first adhesive layer 1 and the second adhesive layer 2, and is easy to tear off, and a protective layer 4 is compounded on the upper surface of the first adhesive layer 1, the protective layer 4 has strong adhesion to the first adhesive layer 1, and the surface has a reflective effect, thereby reducing aging caused by the sun.
[0017] When laying the roll material, after the first row is laid, the first adhesive layer 1 and the second adhesive layer 2 are torn apart along the position of the isolation layer 3, and then a portion of the roll material that needs to be laid again is pressed onto the upper surface of the second adhesive layer 2. At this time, the connection between the two second adhesive layers 2 has a very good waterproof effect at the connection position because the two have great viscosity. When the row position is laid, the first adhesive layer 1 is pressed and adhered to the surface of the protective layer 4. At this time, secondary sealing is performed to further improve the waterproof performance.
[0018] The isolation layer 3 includes a support layer 5, the upper surface of the support layer 5 is compounded with a high-strength adhesive layer 6, the high-strength adhesive layer 6 is connected to the first adhesive layer 2, and the lower surface of the support layer 5 is compounded with a low-strength adhesive layer 7, the low-strength adhesive layer 7 is connected to the second adhesive layer 2, the high-strength adhesive layer 6 has greater viscosity than the low-strength adhesive layer 7, so the second adhesive layer 1 is easier to tear off from the surface of the isolation layer 3. When laying the second row of rolls, it is necessary to ensure that the isolation layer 3 is adhered to the surface of the first adhesive layer 1 to prevent it from sticking to the wrong position during laying.
[0019] The edge of the isolation layer 3 protrudes from the edges of the first adhesive layer 1 , the second adhesive layer 2 and the protective layer 4 , so that it is convenient to pick up the isolation layer 3 for tearing.
[0020] The end of the isolation layer 3 is tilted close to the protective layer 4 , so that when the isolation layer 3 is pulled up, it is easier to separate the second adhesive layer 2 from the isolation layer 3 .
[0021] It should be noted that the utility model is a flexible weather-resistant building waterproof membrane. When in use, when the membrane is laid, after the first row is laid, the first adhesive layer 1 and the second adhesive layer 2 are torn apart along the position of the isolation layer 3. Since the viscosity of the high-strength adhesive layer 6 is greater than that of the low-strength adhesive layer 7, the second adhesive layer 2 is more easily torn apart from the surface of the isolation layer 3. The isolation layer 3 is adhered to the surface of the first adhesive layer 1, and then a part of the membrane that needs to be laid again is pressed onto the upper surface of the second adhesive layer 2. At this time, the connection between the two second adhesive layers 2 has a very good waterproof effect at the connection position because the two have great viscosity. When the row position is laid, the isolation layer 3 is torn off the surface of the first adhesive layer 1, and then the first adhesive layer 1 is pressed and adhered to the surface of the protective layer 4. At this time, secondary sealing is performed to further improve the waterproof performance.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
