[0026] A process for preparing a crack-resistant waterproof roll material, the process comprising the following steps:

[0027] Step 1: After drying the carcass, immerse it in asphalt rubber so that the asphalt rubber is coated on the upper and lower surfaces of the carcass;

[0028] Step 2: Laminating the lower surface of the carcass with a film, and sealing the asphalt rubber under the carcass with the film;

[0029] Step 3: using a preparation device to press a strip groove pattern on the asphalt rubber material on the upper surface of the carcass;

[0030] Step 4: Cover the asphalt rubber material with the pattern pressed on the upper surface of the carcass with a protective film and air-cool it to obtain a waterproof roll;

[0031] Step 5: Cut, roll and pack the waterproof membrane after air cooling.

[0032] By observation Figure 1 According to the process of preparing waterproofing coiled material, the process of drying the carcass and immersing it in asphalt rubber so that the asphalt rubber is coated on the upper and lower surfaces of the carcass; then the lower surface of the carcass is coated with a film to seal the asphalt rubber under the carcass; then a preparation device is used to press a strip groove pattern on the asphalt rubber on the upper surface of the carcass; then a protective film is covered on the asphalt rubber with the pattern pressed on the upper surface of the carcass and air-cooled to solidify the strip groove pattern to obtain a waterproofing coiled material; finally, the air-cooled waterproofing coiled material is cut, rolled and packaged to complete the preparation;

[0033] Through the above process, multiple strip groove patterns can be evenly distributed along the length direction of the carcass, so that the waterproof membrane can be used to pull adjacent waterproof membranes to complete splicing when laying the waterproof membrane, solving the problem that the traditional waterproof membrane is difficult to move horizontally for splicing due to its smooth surface when laying;

[0034] At the same time, after being laid, the multiple strip groove patterns can be used to divert rainwater in rainy weather, so that the rainwater flows out along the multiple strip groove patterns to avoid rainwater accumulation. At the same time, it can be easy to step on in rainy weather, and the raised parts between the multiple strip groove patterns can contact the sole to avoid slipping directly in the rain.

[0035] By observation Figures 5 to 8 According to the figure, an exemplary working process of pressing out a plurality of strip groove patterns is:

[0036] The preparation device comprises a shaft 01 which can rotate around its own axis, a groove 02 on the shaft 01 along the axis direction of the shaft 01, both ends of the groove 02 are open, a plurality of pressing rings 03 are evenly spaced on the shaft 01, a rectangular block is formed on the inner wall of each pressing ring 03, the rectangular block slides in the groove 02, a threaded hole is formed on the rectangular block, a bolt is connected in the threaded hole, and the pressing ring 03 can be locked in the groove 02 by tightening the bolt; during use, the number of pressing rings 03 can be selected according to the number of strip groove patterns pressed on the asphalt rubber material as needed, and then the plurality of pressing rings 03 can be sequentially sleeved on the shaft 01, and the pressing rings 03 can be tightened. The rectangular block slides into the groove 02, and then the bolt is tightened so that the bolt passes through the rectangular block and presses into the groove 02 to lock the position of the pressure ring 03 on the shaft 01, and then the end of the shaft 01 is connected to the output shaft of the motor through a coupling. When the surface of the tire body is covered with a sufficient amount of asphalt rubber, the upper surface of the tire body moves under the shaft 01. At this time, the motor is used to drive the shaft 01 to rotate, so that the shaft 01 drives multiple pressure rings 03 to press on the asphalt rubber on the upper surface of the tire body, and multiple pressure rings 03 are used to press out multiple strip groove patterns on the asphalt rubber on the upper surface of the tire body, thereby realizing continuous processing of strip groove patterns during the continuous movement of the tire body.

[0037] By observation Figures 4 to 9 An exemplary working process that can be flexibly used according to the figure is:

[0038] The preparation device also includes two side rings 04, the inner walls of the two side rings 04 are installed with bearings, both sides of the shaft 01 are installed on the bearings for rotation, the gantry 06 is fixedly connected with a cylinder 07, the lifting and retracting rod of the cylinder 07 is fixedly connected with a hook 08, the two side rings 04 are installed on the hook 08 by bolts, the cylinder 07 can drive the hook 08 to rise and fall, thereby driving the shaft 01 to rise and fall; during use, the cylinder 07 can drive the hook 08 to rise and fall to adjust the distance between the shaft 01 and the asphalt rubber covering the tire body, thereby realizing the distance between multiple pressure rings 03 and the asphalt rubber, and multiple strip groove patterns of different depths can be pressed out by pressing multiple pressure rings 03 into different depths of the asphalt rubber, thereby flexibly preparing waterproof membranes with multiple strip groove patterns of different depths.

[0045] By observation Figures 9 to 11 According to the figure, an exemplary working process for recycling water resources is:

[0046] The lower end of the cover 16 is open, and after the water sprayed on the outer wall of the roller 15 drops down, it can flow out from the lower end of the cover 16, so that it is easy to be collected and reused, avoiding wasting water resources.
