[0041] The present invention will be further described in detail below with reference to the accompanying drawings.

[0042] As Figures 1 to 4 shown, the steps and functions of a preparation process for a high-temperature resistant composite waterproof coiled material will be described in detail below;

[0043] A preparation process for a high-temperature resistant composite waterproof coiled material, the process comprising the following steps:

[0044] Step 1: Drive the base film cylinder I80 between the two tapered wheels II37 to rotate, and the rotation of the base film cylinder I80 drives the base film 10 to pass through the lower ends of the two coating cavities 43;

[0045] Step 2: The two coating cavities 43 are arranged in a staggered manner, and thus two staggered waterproof layers 20 are sprayed on the base film 10;

[0046] Step 3: The two waterproof layers 20 respectively pass through the two shaping wheels 74, and the two shaping wheels 74 press and cast the two waterproof layers 20 to form inclined protrusions 21;

[0047] Step 4: The base film 10 on the base film cylinder II90 passes through the two limiting wheels II35 and is pressed on the upper waterproof layer 20, and is received on the base film cylinder I80 between the two tapered wheels II37.

[0048] A high-temperature resistant composite waterproof coiled material, comprising a base film 10 and two waterproof layers 20 provided on the base film 10, the two waterproof layers 20 are arranged in a staggered manner, the upper waterproof layer 20 is covered with the base film 10, and a plurality of inclined protrusions 21 are provided on the staggered protruding parts of the two waterproof layers 20;

[0049] When in use, lay the first waterproof coiled material on the building, as Figure 4As shown in the figure, the two waterproof layers 20 are arranged in a staggered manner. Each side of the waterproof layer 20 has a certain protruding part. Then, the protruding part of the waterproof layer 20 of the second waterproof coil is pressed on the protruding part of the side of the first waterproof layer 20, thereby completing the overlapping laying between the two waterproof coils. In this way, it can be ensured that there is no protrusion at the connection position between the waterproof coils, ensuring the waterproof performance while also ensuring the connection between the waterproof coils;

[0050] Furthermore, as Figure 4 shown in the figure, a plurality of inclined protrusions 21 are provided on the staggered protruding parts of the two waterproof layers 20. The plurality of inclined protrusions 21 of the waterproof layer 20 on the second waterproof coil are inserted into the plurality of inclined protrusions 21 of the waterproof layer 20 on the first waterproof coil, thereby completing the connection between the waterproof coils. In this way, not only is the waterproof performance of the connection position between the waterproof coils further increased, but also the connection between the waterproof coils is more stable, that is, the waterproof coils are more firmly connected;

[0051] Furthermore, the inclination direction and inclination angle of the inclined protrusion 21 can be adjusted according to different usage requirements by setting the shape of the pressing wheel 74. That is, the inclined convex teeth on the pressing wheel 74 can be set with different inclination angles and inclination directions according to different usage requirements, and do not have to be the same as Figure 13 the inclination direction;

[0052] As Figures 5 to 15 shown in the figure, in order to facilitate the implementation of a preparation process for a high-temperature resistant composite waterproof coil, a preparation device for a high-temperature resistant composite waterproof coil is designed. The structure and function of the preparation device for a high-temperature resistant composite waterproof coil will be described in detail below;

[0053] A preparation device for a high-temperature resistant composite waterproof coil includes a device bracket 31. The rear end of the device bracket 31 is rotatably connected with a limiting wheel I 32. The front end of the device bracket 31 is rotatably connected with two limiting wheels II 35. The rear end of the device bracket 31 is fixedly connected with two telescopic mechanisms I 33. The telescopic ends of the two telescopic mechanisms I 33 are rotatably connected with a conical wheel I 34. The front end of the device bracket 31 is fixedly connected with two telescopic mechanisms II 36. The telescopic ends of the two telescopic mechanisms II 36 are rotatably connected with a conical wheel II 37. A power mechanism for driving the conical wheel II 37 to rotate is fixedly connected to the telescopic end of the telescopic mechanism II 36. The power mechanism is preferably a servo motor;

[0054] A base film cylinder I 80 is clamped between the two conical wheels I 34. A base film cylinder I 80 is clamped between the two conical wheels II 37. A base film 10 is wound between the two base film cylinders I 80;

[0055] Two telescopic mechanisms IX41 are fixedly connected to the device bracket 31. Telescopic mechanisms III42 are fixedly connected to the telescopic ends of the two telescopic mechanisms IX41. Coating cavities 43 are fixedly connected to the telescopic ends of the two telescopic mechanisms III42. Injection pipes 44 are fixedly connected to the two coating cavities 43. Telescopic mechanisms IV45 are fixedly connected to each coating cavity 43. Push plates 46 are fixedly connected to the telescopic ends of each telescopic mechanism IV45. The push plates 46 are slidably connected within the coating cavities 43;

[0056] Two telescopic mechanisms V51 are fixedly connected to the device bracket 31. Telescopic mechanisms VI52 are fixedly connected to the telescopic ends of the two telescopic mechanisms V51. Support plates I53 are fixedly connected to the telescopic ends of the two telescopic mechanisms VI52. Rotating wheels 54 are rotatably connected to the front and rear ends of each support plate I53. A support film is wound between the two rotating wheels 54. The support film passes through the upper side of the support plate I53. The support film can be a plastic film or other films in the prior art, mainly for supporting the formation of the extended part of the waterproof layer 20;

[0057] Two telescopic mechanisms VII61 are fixedly connected to the device bracket 31. Tapered wheels III62 are fixedly connected to the telescopic ends of the two telescopic mechanisms VII61. A base film cylinder II90 is clamped between the two tapered wheels III62. A base film 10 is wound on the base film cylinder II90;

[0058] Two telescopic mechanisms VIII71 are fixedly connected to the device bracket 31. Hydraulic cylinders I72 are fixedly connected to the telescopic ends of each telescopic mechanism VIII71. Rotating cylinders 73 are rotatably connected to the telescopic ends of the two hydraulic cylinders I72. Pressure forming wheels 74 are fixedly connected to each rotating cylinder 73. Hydraulic cylinders II75 are fixedly connected to the telescopic ends of the two hydraulic cylinders I72. Support plates II76 are fixedly connected to the telescopic ends of the two hydraulic cylinders II75. One support plate II76 is located above the pressure forming wheel 74, and the other support plate II76 is located below the pressure forming wheel 74. Communication holes 77 are provided on the rotating cylinder 73. Injection ring cavities 78 are fixedly connected to the telescopic ends of the hydraulic cylinders I72. The injection ring cavities 78 are communicated with the rotating cylinder 73 through the communication holes 77. The rotating cylinder 73 is communicated with the pressure forming wheel 74;

[0059] During use, place the base film cylinder I80 wound with the base film 10 between the two tapered wheels I34. Start the telescopic mechanism I33. The telescopic mechanism I33 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I33 drives the tapered wheel I34 to move. The two tapered wheels I34 move closer to each other. The two tapered wheels I34 clamp the base film cylinder I80. The two tapered wheels I34 can clamp the base film cylinder I80 with different diameters and lengths according to different usage requirements;

[0060] Extend the base film 10 on the base film cylinder I 80, pass it through the upper side of the limit wheel I 32, and then through between the two limit wheels II 35, and wind it around the base film cylinder I 80 located between the two conical wheels II 37. Pre-start the telescopic mechanism II 36. The telescopic mechanism II 36 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 36 drives the conical wheel II 37 to move. The two conical wheels II 37 move closer to each other, and the two conical wheels II 37 clamp the base film cylinder I 80. The two conical wheels II 37 can clamp the base film cylinder I 80 with different diameters and lengths according to different usage requirements;

[0061] Start the power mechanism. The output shaft of the power mechanism starts to rotate. The output shaft of the power mechanism drives the conical wheel II 37 to rotate. The conical wheel II 37 drives the base film cylinder I 80 to rotate. The rotation of the base film cylinder I 80 continuously winds the base film 10 onto the base film cylinder I 80, and thus the base film 10 continuously passes through between the limit wheel I 32 and the limit wheel II 35;

[0062] Pre-place the base film cylinder II 90 between the two conical wheels III 62. Start the telescopic mechanism VII 61. The telescopic mechanism VII 61 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism VII 61 drives the conical wheel III 62 to move. The two conical wheels III 62 move closer to clamp the base film cylinder II 90. The base film 10 on the base film cylinder II 90 passes through between the two limit wheels II 35 and winds around the base film cylinder I 80 located between the two conical wheels II 37;

[0063] Furthermore, start the telescopic mechanism VII 61 to adjust the lateral position of the base film cylinder II 90, so that the base film 10 on the base film cylinder II 90 and the base film 10 on the base film cylinder I 80 are offset by a certain width, which corresponds to the protruding part of the waterproof layer 20;

[0064] Furthermore, pre-connect the injection pipe to the injection pipeline 44. The injection pipe can introduce materials such as asphalt for the waterproof layer 20 into the injection pipeline 44, or other conventional waterproof materials in the field. Start the telescopic mechanism IX 41 and the telescopic mechanism III 42. The telescopic mechanism IX 41 and the telescopic mechanism III 42 can be hydraulic cylinders or electric push rods. The telescopic ends of the telescopic mechanism IX 41 and the telescopic mechanism III 42 drive the coating cavity 43 to move, and thus adjust the height and lateral position of the coating cavity 43, and adjust the position where the coating cavity 43 sprays the waterproof layer 20 on the base film 10. As Figure 5 shown, there are two coating cavities 43. The two coating cavities 43 are offset by a certain position, that is, the position of the first coating cavity 43 is the same as that of the base film 10, and the second coating cavity 43 is laterally offset by a certain width. The offset distance of the coating cavity 43 can be adjusted according to different usage requirements;

[0065] Further, according to the width of the base film 10, the telescopic mechanism Ⅳ 45 is activated. The telescopic mechanism Ⅳ 45 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism Ⅳ 45 drives the push plate 46 to move, so that the push plate 46 slides in the coating cavity 43, thereby adjusting the width of the waterproof layer 20 sprayed from the coating cavity 43;

[0066] Further, in order to ensure that the staggered waterproof layer 20 can be successfully formed, a support plate Ⅰ 53 is provided. As Figure 10 shown, the telescopic mechanism Ⅴ 51 and the telescopic mechanism Ⅵ 52 are activated. The telescopic mechanism Ⅴ 51 and the telescopic mechanism Ⅵ 52 can be hydraulic cylinders or electric push rods. The telescopic ends of the telescopic mechanism Ⅴ 51 and the telescopic mechanism Ⅵ 52 drive the support plate Ⅰ 53 to move, adjusting the position of the support plate Ⅰ 53. A plastic film is wound between the two rotating wheels 54. Then, the extended part of the waterproof layer 20 sprayed from the staggered coating cavity 43 falls on the plastic film. The rotating wheels 54 are driven to rotate continuously. The speed of the plastic film is the same as the speed of the base film 10. Then, after the extended part of the waterproof layer 20 is formed, the waterproof layer 20 is separated from the plastic film, and the spraying of the extended part of the waterproof layer 20 is completed;

[0067] Further, in order to provide inclined protrusions 21 on the extended part of the waterproof layer 20, a profiling wheel 74 is also provided. The telescopic mechanism Ⅷ 71 and the hydraulic cylinder Ⅰ 72 are activated. The telescopic mechanism Ⅷ 71 can be a hydraulic cylinder or an electric push rod. The telescopic ends of the telescopic mechanism Ⅷ 71 and the hydraulic cylinder Ⅰ 72 start to move, driving the profiling wheel 74 to move. There are two profiling wheels 74. One profiling wheel 74 contacts the upper side of the extended part of the lower waterproof layer 20, and the other profiling wheel 74 contacts the lower side of the extended part of the upper waterproof layer 20. Then, when the waterproof layer 20 passes through the profiling wheel 74, the profiling wheel 74 presses inclined protrusions 21 on the waterproof layer 20;

[0068] Further, in order to ensure smooth pressing, a support plate Ⅱ 76 is provided. The two support plates Ⅱ 76 are respectively in contact with the base film 10 and the extended part of the waterproof layer 20. Similar plastic films to those on the rotating wheels 54 can also be provided on the two support plates Ⅱ 76, that is, the lower ends of the two support plates Ⅱ 76 also continuously pass through the plastic film, and the plastic film supports the passing base film 10 and waterproof layer 20. The speed of the plastic film is the same as the speed of the base film 10. Then, the waterproof layer 20 is supported by the support plate Ⅱ 76 to ensure that the profiling wheel 74 completes the extrusion forming of the inclined protrusions 21;

[0069] Further, a material injection ring cavity 78 is also provided. The material injection ring cavity 78 is pre-connected to an injection molding material pipeline, and the injection molding material pipeline continuously feeds asphalt into the material injection ring cavity 78, and then into the profiling wheel 74. During the rotation of the profiling wheel 74, the asphalt continuously flows out from the communication holes 77 provided on the profiling wheel 74, so as to repair and form the inclined protrusions 21 on the waterproof layer 20.
