[0012] Preferably, the support portion is in the form of a concave groove, which is conducive to the integral weaving of the flexible wire and avoids increasing the weight of the ventilation and noise reduction layer.

[0013] More preferably, the support portion is in the form of an inverted conical groove, which has stronger support force and is more stable in structure.

[0025] like Figure 1 As shown in the figure, this utility model embodiment provides a ventilation, noise reduction, drainage and waterproof integrated roll material, which is mainly used for laying on the roof or roof surface of a building. It includes, from bottom to top, an anti-adhesive layer 1, a waterproof layer 2, a self-healing layer 3, a ventilation and noise reduction layer 4 and a protective layer 5.

[0026] The waterproof layer 2 is used for waterproofing and can be made of polymer waterproof materials such as PVC, EVA, TPO or EPDM.

[0027] The anti-sticking layer 1 is coated on the lower surface of the waterproof layer 2, and is used to adhere to other objects such as steel plates, insulation boards or walls during the laying of the roll material, thereby fixing the roll material. The anti-sticking layer 1 is preferably made of polyurethane adhesive, epoxy resin adhesive or polyethylene adhesive.

[0028] The self-healing layer 3 is arranged on the upper surface of the waterproof layer 2 and is fixedly connected to the waterproof layer 2 by a melting or gluing process. The self-healing layer 3 is used to improve the puncture resistance of the roll material and to tightly bind the puncture object when the roll material is punctured, thereby improving the waterproof capability of the roll material when it is punctured. The material of the self-healing layer 3 can be one of pressure-sensitive adhesive, butyl adhesive or modified asphalt adhesive.

[0029] The ventilation and noise reduction layer 4 is arranged above the self-healing layer 3 and is fixedly connected to the self-healing layer 3 by a melting or gluing process. In this embodiment, the melting process is used to improve the connection strength between the ventilation and noise reduction layer 4 and the self-healing layer 3. The ventilation and noise reduction layer 4 has a three-dimensional net-like structure and is hollow. The ventilation and noise reduction layer 4 utilizes the property that sound is not easily transmitted in air to reduce noise. The hollow structure is beneficial to the circulation of air and the removal of water vapor, thereby avoiding the accumulation of water vapor on the waterproof layer 2 and causing the growth of mold or damage to the roof structure. In addition, the ventilation and noise reduction layer 4 can also play a role in preventing roots, thereby avoiding the growth of the roots of plants planted or growing in the wild on the roof into the waterproof layer 2 and damaging the waterproof layer 2.

[0030] The protection layer 5 is arranged above the ventilation and noise reduction layer 4 and is fixedly connected to the ventilation and noise reduction layer 4. The protection layer 5 is used to protect the hollow space of the ventilation and noise reduction layer 4, thereby preventing objects such as soil from entering the ventilation and noise reduction layer 4 and affecting the ventilation and noise reduction capability of the ventilation and noise reduction layer 4.

[0031] The protection layer 5 is a water-permeable cloth layer, which is preferably a polyester short fiber non-woven geotextile and is fixedly connected to the ventilation and noise reduction layer 4 by a needling process or a melting process, thereby improving the connection strength between the protection layer 5 and the ventilation and noise reduction layer 4. The water-permeable cloth layer can filter solid objects such as soil and dust, while allowing water to be removed. In addition, the polyester short fiber non-woven geotextile has a light weight and does not increase the overall weight of the roll material, thereby allowing the roll material to be applied to the laying of a lightweight roof.

[0032] More specifically, the ventilation and noise reduction layer 4 of this embodiment includes a planar connecting portion 41 for supporting and connecting the protection layer 5. The planar connecting portion 41 is arrayed with a plurality of vertical supporting portions 42, thereby supporting a hollow three-dimensional shape. The ventilation and noise reduction layer 4 has an increased ability to maintain the three-dimensional shape by the supporting portions 42, thereby providing stronger support and avoiding being flattened by the attachment of objects such as soil and plants on top and losing the ventilation and noise reduction capability. In addition, the supporting portions 42 are sunk into the self-healing layer 3 by a melting process and are connected to the self-healing layer 3, thereby improving the connection strength between the ventilation and noise reduction layer 4 and the self-healing layer 3.

[0033] The ventilation and noise reduction layer 4 is integrally and irregularly woven by flexible filaments made of polypropylene, polyester fiber or nylon material.

[0034] Preferably, the support part 42 is in the shape of a concave groove, which is conducive to the fact that the ventilation and noise reduction layer 4 is integrally woven by the flexible wire, while avoiding the increase of the weight of the ventilation and noise reduction layer 4.

[0035] More preferably, the support part 42 is in the shape of an inverted conical frustum groove, which has stronger support force and more stable structure.

[0036] In order to ensure that the support part 42 has better support force, the taper of the support part 42 is preferably between 2 / 3 and 1.

[0037] In order to ensure the three-dimensional structural strength of the ventilation and noise reduction whole, the diameter of the bottom surface of the support part 42 is preferably 0.4-0.6 cm, the height is preferably 1-1.5 cm, and the spacing between adjacent support parts 42 is preferably 0.5-1 cm.

[0038] The ventilation and noise reduction drainage waterproof integrated coiled material provided by the utility model can be integrally manufactured in advance, can integrate waterproof, ventilation and noise reduction, drainage, can improve the combination and connection performance between layers, can form an integrated whole, can improve the service life of the coiled material, can increase the structural strength after the roof is laid, and can greatly reduce the workload and difficulty of workers who directly lay the integrated coiled material instead of layer-by-layer laying operation, thereby improving the work efficiency.
