Technical Field

[0001] This invention belongs to the field of waterproof membrane production, and particularly relates to a modified bitumen waterproof membrane and its production process. Background Technology

[0002] Waterproof membrane refers to a waterproof material product made by impregnating a base material with asphalt or polymer-based waterproofing materials. It is supplied in roll form and is called waterproof membrane. It is mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. It is a flexible building material that can be rolled up to prevent leakage between the foundation and the building, serving as the first line of defense for waterproofing the entire project and playing a crucial role. When installing waterproof membrane on prefabricated steel structures, workers need to align the membrane with the steel panels. Slight carelessness can result in misaligned application and damage. Therefore, a waterproof membrane with auxiliary functions is needed. Summary of the Invention

[0027] The present invention will be described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0028] A process for producing modified bitumen waterproof membrane includes the following steps:

[0029] Step 1: Add the auxiliary materials to the asphalt in a certain proportion and mix and heat to obtain the modified asphalt in a molten state;

[0030] Step 2: Add the modified asphalt to the production unit and cool and mold the modified asphalt to obtain the billet;

[0031] Step 3: Extrude multiple dashed grooves and two solid grooves onto the billet, and sprinkle fragmented aluminum foil onto the billet;

[0032] Step 4: Scrape off any loose aluminum foil from the billet and recycle the aluminum foil;

[0033] Step 5: Remove the blank, apply self-adhesive to the bottom surface of the blank and attach release paper to obtain the modified bitumen waterproof membrane;

[0034] Step Six: Roll up and package the modified bitumen waterproof membrane.

[0035] The auxiliary materials include asbestos and rubber powder.

[0036] The spacing between the multiple dashed grooves is equal.

[0037] See Figure 3-6 The diagram shows a schematic of how multiple dashed grooves and two solid grooves can be extruded onto modified asphalt according to the present invention. Further,

[0038] The production device includes a base 102, on which a forming roller 101 is rotatably connected via bearings. Two connecting pipes 103 are welded and fixedly connected to the forming roller 101. A rotating frame 201 is rotatably connected to the base 102 via bearings. A first pressure roller 204 and a second pressure roller 301 are rotatably connected to the rotating frame 201 via bearings. The second pressure roller 301 has multiple mounting holes 302, multiple strip-shaped protrusions 303, and multiple semi-circular protrusions 304. Two semi-circular protrusions 304 can be spliced ​​together to form an annular protrusion. Both the semi-circular protrusions 304 and the strip-shaped protrusions 303 can be fixed to the second pressure roller 301 by pins.

[0039] The base 102 is used to support the forming roller 101. The forming roller 101 is hollow inside. By connecting the two connecting pipes 103 to the cooling equipment, cooling oil can be introduced into the forming roller 101 to achieve the cooling function. The first pressure roller 204 and the second pressure roller 301 are both used to extrude the modified asphalt.

[0040] When using the production equipment, the operator first controls the rotating frame 201 to rotate so that the first pressure roller 204 is close to the forming roller 101. Then, the forming roller 101 is controlled to rotate clockwise, and molten modified asphalt is added between the forming roller 101 and the first pressure roller 204. The forming roller 101 and the first pressure roller 204 work together to squeeze the modified asphalt. Under the action of friction, the first pressure roller 204 rotates relative to the forming roller 101, thereby evenly spreading the modified asphalt on the surface of the forming roller 101.

[0041] After the modified asphalt on the forming roller 101 has cooled for a period of time, the operator controls the rotating frame 201 to rotate again. The first pressure roller 204 separates from the forming roller 101, causing the second pressure roller 301 to adhere to the surface of the modified asphalt. The forming roller 101 and the second pressure roller 301 rotate relative to each other. During the rotation of the second pressure roller 301, multiple strip-shaped protrusions 303 can extrude multiple dotted grooves on the modified asphalt. This makes it easier for construction workers to align the dotted grooves with the protrusions on the roof during the construction of the color steel roof, thereby avoiding the phenomenon of the waterproof membrane being skewed as a whole. The strip-shaped protrusions 303 can be pulled out and inserted into other installation holes 302 to realize the function of adjusting the position of the strip-shaped protrusions 303. By adjusting the spacing between multiple strip-shaped protrusions 303, the width between multiple dotted grooves is equal to the spacing between the protrusions of the color steel roof. Waterproof membranes suitable for different color steel roofs can be produced according to actual needs.

[0042] Two semi-circular protrusions of 304 stainless steel can be spliced ​​together to form a ring protrusion. The two ring protrusions press two solid grooves into the modified bitumen. The solid grooves make it easier for construction workers to cut the waterproof membrane according to actual needs, remove excess scraps, and cut along the solid grooves to avoid cutting the waterproof membrane crookedly.

[0043] The use of dashed and solid lines in the grooves helps staff distinguish their functions.

[0044] See Figure 5 A schematic diagram of an embodiment of the present invention capable of driving the rotating frame 201 to rotate is shown. Further,

[0045] A cylinder 202 is rotatably connected to the base 102 via a bearing, and the moving end of the cylinder 202 is rotatably connected to the rotating frame 201.

[0046] By controlling the extension and retraction of the moving end of the cylinder 202, the rotating frame 201 can be driven to rotate, which facilitates the control of the movement of the first pressure roller 204 and the second pressure roller 301.

[0047] See Figure 7-10 A schematic diagram of an embodiment of the present invention capable of uniformly laying aluminum foil is shown. Further,

[0048] A storage box 401 is fixedly connected to the base 102 by bolts. A turning roller 402 is rotatably connected to the storage box 401 through a bearing. An opening is provided at the lower end of the storage box 401. A baffle 403 is rotatably connected above the opening. A brush 406 is fixedly connected to the lower part of the opening by bolts. A pulley 104 is fixedly connected to the storage box 401 and one of the connecting pipes 103 by a key. The two pulleys 104 are connected by a synchronous belt.

[0049] With the combined action of two pulleys 104 and a synchronous belt, the forming roller 101 drives the turning roller 402 to rotate synchronously. The storage box 401 is used to store fragmented aluminum foil. While processing the dotted groove and the solid groove, the operator controls the baffle 403 to rotate upward and open. At the same time, the turning roller 402 rotates and pushes the aluminum foil in the storage box 401 out of the opening. The aluminum foil is scattered on the surface of the modified asphalt. As the forming roller 101 rotates, the brush 406 spreads the scattered aluminum foil evenly, making it evenly distributed on the surface of the modified asphalt. Finally, the second pressure roller 301 cooperates with the forming roller 101 to squeeze the aluminum foil, so that the aluminum foil adheres to the surface of the modified asphalt and in the dotted groove and the solid groove, achieving the effect of evenly laying the aluminum foil.

[0050] See Figure 9-10 A schematic diagram of an embodiment of the present invention that enables aluminum foil recycling is shown. Further,

[0051] A vacuum box 501 is welded and fixedly connected to the upper end of the storage box 401. Multiple vacuum pipes 502 are fixedly connected to the vacuum box 501 by bolts. A mesh 503 is installed between the vacuum box 501 and the storage box 401.

[0052] Multiple suction pipes 502 are connected to a suction pump. After the aluminum foil in the storage box 401 is laid out, the brush 406 can scrape off the loose aluminum foil on the surface of the modified asphalt. Then, the loose aluminum foil is sucked back into the storage box 401 through the multiple suction pipes 502, thus realizing the function of aluminum foil recycling. The mesh 503 plays a filtering role to prevent the aluminum foil from being sucked into the suction box 501.

[0053] See Figure 5 and Figure 10 A schematic diagram of an embodiment of the invention, which enables automatic control of the opening and closing of the baffle 403, is shown. Further,

[0054] A contact rod 404 is fixedly connected to the baffle 403 by bolts, a lever 203 is fixedly welded to the rotating frame 201, and a torsion spring 405 is fixedly welded between the contact rod 404 and the storage box 401.

[0055] The baffle 403 automatically blocks the opening under the action of the torsion spring 405, preventing the aluminum foil from being discharged. When the rotating frame 201 rotates and drives the second pressure roller 301 to approach the modified asphalt, the rotating frame 201 drives the contact rod 404 to contact the lever 203. The lever 203 drives the baffle 403 to rotate upward, thereby opening the opening and discharging the aluminum foil. When the lever 203 disengages from the contact rod 404, the baffle 403 automatically resets under the action of the torsion spring 405, blocking the opening again.

[0056] See Figure 3 A schematic diagram of an embodiment of the present invention capable of driving the forming roller 101 to rotate is shown. Further,

[0057] A drive motor 601 is fixedly connected to the base 102 by bolts. Gears 602 are fixedly connected to the output shaft of the drive motor 601 and one of the connecting pipes 103. The two gears 602 mesh and transmit power.

[0058] The drive motor 601 drives two gears 602 to mesh and transmit power, thereby driving one of the connecting pipes 103 to rotate, which in turn drives the forming roller 101 to rotate.

[0059] The surface of the waterproof membrane is provided with dotted grooves and solid grooves.
