Description

Technical Field

[0001] The utility model relates to a hot-melt self-adhesive waterproof coiled material, in particular to a heating and melting structure thereof, and belongs to the technical field of waterproof coiled materials. Background Art

[0002] The waterproofing membrane made of butyl rubber has the advantages of being small and easy to construct. It is especially suitable for people without construction experience. It is widely used in utensils, pipes, and building surfaces. Butyl rubber has the characteristic of slow flow, which can penetrate deep into the gap, fill the gap, and prevent rainwater from entering the gap. The flow speed is positively correlated with the temperature. The higher the temperature, the faster the gap is filled, and the lower the temperature, the slower the flow, until it condenses and cannot fill the gap, loses the waterproof effect, and rainwater leaks through the gap. Therefore, how to increase the temperature and promote the penetration of high-butyl rubber into the gap is a technical problem that technicians in this field need to solve urgently.

[0016] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0017] See attached Figure 1-2 As shown, a hot-melt self-adhesive waterproof coiled material in this embodiment includes an aluminum foil layer 2 and a waterproof layer 9. The aluminum foil layer 2 is superimposed and bonded to the waterproof layer 9, and both ends of the aluminum foil layer 2 are connected to electric heating devices.

[0018] Aluminum foil is used as an attachment material for the waterproof layer, and it can also reflect sunlight and reduce the temperature of the building. Electric heating devices are connected to both ends of the aluminum foil layer 2. Current is formed in the aluminum foil layer 2, generating heat to heat the waterproof layer 9. After being heated, the waterproof layer 9 melts, has stronger fluidity, and is easier to penetrate into the gap, fill the gap, and prevent rainwater from passing through the gap. Thus, a waterproof effect is achieved. It utilizes the property of the aluminum foil layer 2 that it conducts electricity and generates heat, and solves the defects of the waterproof layer 9 condensing and having poor fluidity in a low-temperature environment. It is particularly suitable for construction work in cold weather.

[0019] In order to facilitate the packaging and transportation of the hot-melt self-adhesive waterproof coiled material, the utility model is further configured as follows: the two ends of the aluminum foil layer 2 are detachably connected to the electric heating device. When packaging and transporting, the electric heating device is removed and packaged and transported separately. During construction, the two ends of the aluminum foil layer 2 are connected to the electric heating device until the waterproof layer 9 melts, and then the electric heating device is removed.

[0020] The utility model is further configured as follows: the electric heating device includes a power supply 13, a transformer 12, a pair of wires 11 and a pair of electric clamps 10, the power supply 13 supplies power to the transformer 12, the transformer 12 is respectively connected to a pair of electric clamps 10 through a pair of wires 11, and the pair of electric clamps 10 respectively clamp the two ends of the aluminum foil layer 2. The power supply 13 supplies power to the transformer 12, converts high voltage electricity into safe low voltage electricity, and is electrically connected to the two ends of the aluminum foil layer 2 through a pair of wires 11 and a pair of electric clamps 10, so as to form an electric path in the aluminum foil layer 2 and generate heat. Since the aluminum foil layer 2 is superimposed on the waterproof layer 9, the heat is transferred to the waterproof layer 9, the waterproof layer 9 melts and penetrates into the gap. Preferably, the transformer 12 is a multi-speed adjustable transformer.

[0021] In order to facilitate the connection of the two ends of the aluminum foil layer 2 by the electric clamp 10, the utility model is further configured as follows: the waterproof layer 9 is superimposed on the middle section of the aluminum foil layer 2; the aluminum foil layer 2 is longer than the waterproof layer 9, and the two ends of the aluminum foil layer 2 are clamped by a pair of electric clamps 10. The two ends of the aluminum foil layer 2 are exposed separately beyond the waterproof layer 9, and the electric clamp 10 only clamps the two ends of the aluminum foil layer 2 without contacting the waterproof layer 9. The molten waterproof layer 9 will not contaminate the electric clamp 10.

[0022] In order to enhance the tensile strength of the waterproof layer 9, the utility model is further configured as follows: the waterproof layer 9 comprises a first butyl rubber layer 3, a non-woven fabric layer 4 and a second butyl rubber layer 5 which are sequentially stacked and bonded, and the aluminum foil layer 2 is bonded to the first butyl rubber layer 3. The non-woven fabric layer 4 is difficult to stretch, thereby increasing the overall tensile strength of the waterproof layer 9.

[0023] The utility model is further configured as follows: an isolation film layer 6 is bonded onto the second butyl rubber layer 5 .

[0024] In order to prevent the aluminum foil layer 2 from oxidation and deterioration, the utility model is further configured as follows: the aluminum foil layer 2 is coated with an anti-oxidation coating 1 on the side facing away from the waterproof layer 9. The side of the aluminum foil layer 2 facing the waterproof layer 9 is still conductive and electrically connected to the electrical clamp 10.

[0025] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
