[0002] In experiments on the production of non-woven asphalt roofing membranes, modified asphalt overlay is typically applied directly to a stress-free membrane, and then other membrane materials are placed on top of the overlay, resulting in relatively smooth experimental samples. However, in actual production, the membrane is usually stretched, generating stress and causing numerous wrinkles on the membrane surface. The experimental samples differ from the actual produced membranes, potentially leading to unreliable performance measurements. Therefore, a more realistic experimental setup for producing non-woven asphalt roofing membranes is needed. Utility Model Content

[0023] According to some embodiments of this utility model, a tireless asphalt discharge experimental device is provided, such as... Figure 1As shown, the system includes: a base 1, suitable for supporting a release membrane (not shown) and an upper surface membrane (not shown), with an upwardly extending support 11 formed at the first end of the base 1 for supporting the upper surface membrane; a first fixing mechanism 23, disposed at the second end of the base 1 opposite to the first end, configured to fix the release membrane laid on the base 1 and the upper surface membrane laid on the release membrane, with non-tire bitumen coated between the release membrane and the upper surface membrane; a second fixing mechanism 22 and a third fixing mechanism 21, respectively installed at the lower and upper parts of the support 11, configured to fix the release membrane and the upper surface membrane respectively; a rolling mechanism 3, installed on the base 1, configured to roll the upper surface membrane located at the second end onto the non-tire bitumen; and a first traction mechanism 41 connected to the first fixing mechanism 23, configured to apply stress to the upper surface membrane and the release membrane by traction of the first fixing mechanism 23.

[0024] Specifically, according to some embodiments of this utility model, when the above-mentioned device is working, the isolation membrane is first laid on the base 1, and the two ends of the isolation membrane are fixed by the first fixing mechanism 23 and the third fixing mechanism 21 respectively. The first traction mechanism 41 is adjusted so that the first fixing mechanism 23 moves while the isolation membrane is fixed, thereby applying a certain amount of stress to the isolation membrane. Then, the tireless asphalt is coated on the isolation membrane by scraping. Next, the two ends of the upper surface membrane are fixed by the first fixing mechanism 23 and the second fixing mechanism 22 respectively, and the upper surface membrane is rolled onto the tireless asphalt by the rolling mechanism 3. The first traction mechanism 41 is then adjusted so that the first fixing mechanism 23 moves while the upper surface membrane and the isolation membrane are fixed, thereby applying a certain amount of stress to the upper surface membrane and the isolation membrane. This makes the tireless asphalt discharge experiment more closely resemble the actual production situation and improves the accuracy of the experimental test.

[0025] According to some embodiments of the present invention, the bracket 11 includes a frame 111 perpendicular to the base 1 and a platform 112 disposed on the frame 111 and parallel to the base 1, and a third fixing mechanism 21 is installed on the platform 112.

[0026] According to some embodiments of the present invention, the above-mentioned tireless asphalt discharge test device further includes a second traction mechanism 42, which is installed on the platform 112 and connected to the third fixing mechanism 21. The third fixing mechanism 21 can be moved while fixing the upper surface film by traction of the third fixing mechanism 21, thereby applying stress to the upper surface film.

[0027] According to some embodiments of the present invention, each of the first fixing mechanism 23, the second fixing mechanism 22 and the third fixing mechanism 21 includes a pressure block 211, which is configured to move away from or towards the upper surface film and / or the isolation film by means of a first bolt 212 to fix or release the upper surface film and / or the isolation film. Specifically, after the release membrane is laid on the base 1, the first bolt 212 on the first fixing mechanism 23 and the second fixing mechanism 22 is rotated, causing the pressure block 211 to move closer to the release membrane to press the release membrane onto the base 1; after the release membrane is coated with non-tire asphalt, the first bolt 212 on the first fixing mechanism 23 is rotated, causing the pressure block 211 to move away from the release membrane to release the release membrane; then the first bolt 212 on the first fixing mechanism 23 is rotated again, causing the pressure block 211 to move closer to the upper surface membrane and the release membrane to press the upper surface membrane and the release membrane onto the base 1; at the same time, the first bolt 212 on the third fixing mechanism 21 is rotated, causing the pressure block 211 to move closer to the upper surface membrane to press the upper surface membrane onto the platform 112.

[0028] According to some embodiments of the present invention, each of the first traction mechanism 41 and the second traction mechanism 42 includes: a fixed block 411, configured to be fixed relative to the base 1; a slider 412, slidably disposed relative to the fixed block 411 via a first slide rail (not shown), wherein a first bolt 212 on the first fixing mechanism 23 and / or the third fixing mechanism 21 is threadedly connected to the slider 412, such that the first fixing mechanism 23 and / or the third fixing mechanism 21 moves with the slider 412 to tighten the upper surface film and / or the isolation film; and a spring 413, with its two ends connected to the slider 412 and the fixed block 411 respectively, configured to deform when the slider 412 moves relative to the fixed block 411 to change the tension applied to the upper surface film and the isolation film. A second bolt 414 is fixedly connected to the slider 412 and can move with the rotation of the second bolt 414 to deform the spring 413.

[0029] Specifically, according to some embodiments of this utility model, the first traction mechanism 41 and the second traction mechanism 42 are fixedly connected to the first fixing mechanism 23 and the third fixing mechanism respectively via a slider 412. When adjusting the first traction mechanism 41, rotating the second bolt 414 on the first traction mechanism 41 causes the slider 412 to move with the rotation of the second bolt 414, thereby driving the first fixing mechanism 23 to move and applying tension to the upper surface film and / or the isolation film fixed on the first fixing mechanism 23. At this time, the spring 413 is compressed, and at the same time, it generates elastic force on the slider 412, causing the tension of the first fixing mechanism 23 on the upper surface film and / or the isolation film to change. Thus, the magnitude of the stress in the film material can be calculated by measuring the deformation of the spring, further improving the accuracy of subsequent experiments. The working process of the second traction mechanism 42 is similar and will not be described in detail here.

[0030] According to some embodiments of the present invention, the compaction mechanism 3 includes: a second slide rail 31, mounted on the frame 111; and a pressure roller 32, mounted on the frame 111 via the second slide rail 31, configured to move along the second slide rail 31 on the frame, so that the pressure roller 32 presses the upper surface film onto the asphalt. Specifically, after the first fixing mechanism 23 and the third fixing mechanism 21 fix the upper surface film, the pressure roller 32 moves towards the base 1 via the second slide rail 31, thereby pressing the upper surface film onto the asphalt.

[0031] According to some embodiments of this utility model, the above-mentioned tireless asphalt discharge test device further includes a cooling mechanism 5, disposed inside the base 1, including a cooling channel 51 formed inside the base 1 for condensate to pass through. Figure 2 As shown, condensate is introduced into the cooling channel 51 during discharge to cool the upper surface film and the isolation film.

[0032] In some embodiments, the release film is a transparent PET silicone-coated release film, for example, with a thickness of 40 μm and a width of 1040 mm; the upper surface film is a PET film, for example, with a thickness of 45 μm and a width of 970 mm; and the non-woven asphalt is a general self-adhesive modified asphalt.

However, these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Although various embodiments have been described above, this does not mean that the measures in the various embodiments cannot be used advantageously in combination. The scope of the present invention is defined by the appended claims and their equivalents. Various substitutions and modifications can be made by those skilled in the art without departing from the scope of the present invention, and all such substitutions and modifications should fall within the scope of the present invention.
