Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coiled materials, in particular to a butyl self-adhesive TPO polymer waterproof coiled material. Background Art

[0002] The butyl coiled material is a synthetic polymer waterproof sheet made of butyl rubber as the main material, supplemented by a variety of additives, through processes such as mixing, refining, and calendering, and processed by an advanced domestic fully automated production line. The butyl coiled material can be applied on any dry and firm base surface. It is suitable for the waterproofing, moisture-proofing, and anti-seepage of the roofs, basements, toilets and bathrooms of industrial and civil buildings, subway projects, bridge culverts, and water conservancy projects in various climatic environments, the waterproofing of color steel tiles and color steel plates, and the repair projects of various old roofs.

[0003] At present, most butyl coiled materials are laid outdoors and use low-molecular butyl or polyisobutylene materials. These materials are close to liquid state itself and have strong initial adhesion, and can achieve good bonding effects in the initial stage.

[0004] However, due to the relatively small molecular weight of traditional butyl coiled materials, they are easily degraded and aged in outdoor ultraviolet environments and high-temperature and high-humidity environments, and it is difficult to achieve long-term sealing and water-blocking effects. Summary of the Utility Model

[0005] This application provides a butyl self-adhesive TPO polymer waterproof coiled material, which is convenient for improving the waterproofness and anti-aging property of the butyl coiled material.

[0006] A butyl self-adhesive TPO polymer waterproof coiled material provided by this application adopts the following technical solutions:

[0007] A butyl self-adhesive TPO polymer waterproof coiled material includes a TPO polymer layer. The TPO polymer layer is divided into three layers, namely an upper TPO layer, a middle TPO layer, and a lower TPO layer. A first isolation layer is arranged between the upper TPO layer and the middle TPO layer, a second isolation layer is arranged between the middle TPO layer and the lower TPO layer. Isolation membranes are arranged in both the first isolation layer and the second isolation layer. A composite butyl raw rubber is bonded to the surface of the isolation membrane. An upper waterproof layer is arranged at the top of the upper TPO layer, and a lower waterproof layer is arranged at the bottom of the lower TPO layer.

[0008] By adopting the above technical solution, a butyl self-adhesive TPO polymer waterproof coiled material designed by the utility model has high flexibility during use. The TPO polymer will not become brittle due to the migration of plasticizers and maintains long-term waterproof function. Therefore, the waterproof coiled material composed of the TPO polymer has stronger waterproof property. By setting three layers of TPO layers, good waterproof property is ensured for each part of the coiled material. Secondly, an isolation layer is arranged between each TPO layer, and an isolation film made of composite butyl raw rubber is arranged in the isolation layer, which can ensure that each TPO layer is more firmly bonded. Finally, waterproof layers are arranged at the top of the upper TPO layer and the bottom of the lower TPO layer to better enhance the waterproof effect of the TPO polymer layer.

[0009] Preferably, corrosion prevention layers are arranged at the top of the upper waterproof layer and the bottom of the lower waterproof layer, and the corrosion prevention layer adopts PVDF.

[0010] By adopting the above technical solution, the arranged corrosion prevention layer is convenient for improving the corrosion resistance of the coiled material; the arranged PVDF layer has strong resistance to chemical substances such as acids, alkalis, and salts, so the corrosion resistance is better.

[0011] Preferably, a non-woven fabric is adhesively bonded to the surface of the composite butyl raw rubber, and the non-woven fabric is made of polyester fiber.

[0012] By adopting the above technical solution, the arranged non-woven fabric is made of polyester fiber and is composed of 100% fibers with porosity and good air permeability.

[0013] Preferably, an anti-aging layer is arranged at the top of the corrosion prevention layer, the anti-aging layer is composed of epoxy resin, and a protective layer is arranged at the top of the anti-aging layer.

[0014] By adopting the above technical solution, the arranged anti-aging layer is convenient for improving the anti-aging property of the coiled material. The specially treated epoxy resin can resist oxidation and aging in the environment. The arranged protective layer is convenient for preventing damage to the coiled material during processing or contact with the outside world. It is composed of fine sand and adhesive, which better improves the protection effect of the protective layer.

[0015] Preferably, nylon threads for fixation are arranged between the anti-aging layer and the corrosion prevention layer.

[0016] By adopting the above technical solution, the arranged nylon threads are convenient for fixing the anti-aging layer and the corrosion prevention layer by stretching the nylon threads to prevent the anti-aging layer and the corrosion prevention layer from separating.

[0017] Preferably, an aluminum film is attached to the lower surface of the lower TPO layer.

[0018] By adopting the above technical solution, the arranged aluminum film is convenient for improving the oxidation resistance and heat resistance of the coiled material.

[0019] Preferably, a thin film is provided on the bottom surface of the corrosion prevention layer at the bottom of the lower waterproof layer.

[0020] By adopting the above technical solution, the provided thin film has better ductility when the coil needs to be rolled up for use or transportation, and prevents the coil from being damaged when it is placed on the transportation device in a curled state.

[0021] By adopting the above technical solution,

[0022] In summary, the present application has the following beneficial effects:

[0023] 1. An isolation layer is provided between each TPO layer, and an isolation film made of composite butyl raw rubber is provided inside the isolation layer, which can ensure that each TPO layer is bonded more firmly;

The non-woven fabric 12 is made of polyester fiber. An upper waterproof layer 9 is provided on the top of the upper TPO layer 2, and a lower waterproof layer 10 is provided on the bottom of the lower TPO layer 4. The upper waterproof layer 9 and the lower waterproof layer 10 are used to enhance the waterproof performance of the TPO polymer layer 1. An aluminum film 15 is attached to the lower surface of the lower TPO layer 4. The aluminum film 15 includes the bottom surface and the side surface of the lower TPO, and the aluminum film 15 can prevent the lower TPO layer 4 from being oxidized.
