Problems solved by technology

At the same time, the mechanism of compounding the modified material on the tire cloth based on the tire cloth is also the focus of affecting the quality of the waterproof membrane, that is, the production line for processing the waterproof membrane directly affects the quality of the waterproof membrane. It is relatively large, and the tire cloth needs to be processed into waterproof membranes through the above-mentioned multiple processes, but the existing production line has certain defects: on the input side of the production line, the tire cloth is generally in place on the tire cloth integrated frame and is on standby , there is a structure capable of conveying the tire cloth through the motor drive connection, such as a storage round roller, the tire cloth will generally be wound on the storage round roller, and then driven by the motor to drive the storage round roller to rotate, thereby conveying to the production line In the process of transporting the tire cloth with the above-mentioned round roller and other mechanisms, the tire cloth is often torn or piled up due to the abnormal operation of the round roller. It is caused by working according to the preset ratio, which directly affects the production efficiency and production quality; in addition, the existing production line is used to dry the waterproof membrane after the waterproof membrane is processed. , although it can play a certain role in drying, but due to the influence of the structure of the waterproof membrane itself, the simple use of the conveyor belt cannot fully dry the processed waterproof membrane, which also leads to a large amount of moisture in the final rolled waterproof membrane and oil, etc., which is not conducive to later storage and transportation

Embodiment 1

[0077] see Figure 7 as shown, Figure 7 Show the production process of the modified material of embodiment one and the process flow diagram of the modified material after production when processing the waterproof coiled material; Raw material 90# asphalt is first driven into the asphalt storage tank by the pump (with a heat-conducting oil coil pipe inside) ), after the temperature rises from 90°C to 120°C, pump it into the mixing tank, then add the engine oil into the tank, heat up to 180°C, add SBS, grind and self-circulate through the colloid mill, after 0.5 hours. Continue to maintain temperature control at 185°C to 195°C for a sufficient time of 2 hours after the addition of SBS, continue to add polypropylene or polyethylene particles, maintain the temperature at 185°C to 195°C for sufficient time for 2 hours, and then put in powder. After fully stirring for 2 hours, it can be kept warm and stirred. At this time, samples can be taken for analysis. When the test result ...

Embodiment 2

[0080] see Figure 8 as shown, Figure 8 Show the production process of the modified material of embodiment two and the process flow diagram of the modified material after production when processing waterproof coiled material; Raw material 100# asphalt, at first squeezed into asphalt storage tank by pump (set heat-conducting oil pan inside tube), after the temperature rises to 90℃~120℃, pump it into the mixing tank, then add the engine oil into the tank, heat up to 185-195℃, mix the rubber powder fully for 2 hours, and then continue to keep the temperature at 185- 195°C, add polyethylene material and polypropylene granules, stir well for 2 hours, while keeping the temperature at 185-195°C, put the powder into the mixing tank. Keep the temperature controlled at 185-195°C, stir well for 2 hours, and take samples for analysis. After passing the inspection, the material can be supplied to the molding machine. That is, it is introduced into the dip coating tank 3 of the producti...

Embodiment 3

[0083] see Figure 9 as shown, Figure 9 Show the production process of the modified material of embodiment three and the process flow diagram of the modified material after production when processing the waterproof coiled material; Raw material 90# asphalt is first driven into the asphalt storage tank by the pump (with heat-conducting oil coil pipe inside) ), after the temperature rises from 90°C to 120°C, pump it into the mixing tank, then add engine oil into the tank, heat up to 180°C, add SBS and SBR, grind and self-circulate through the colloid mill, after 0.5 hours. Continue to maintain the temperature control at 185°C to 195°C, and ensure that the time is sufficient for 2 hours after the SBS is added, and then put in the powder. After fully stirring for 2 hours, it can be kept warm and stirred. At this time, samples can be taken for analysis. Keep the temperature controlled at 160-170°C. When the test result is qualified, the material can be discharged to the moldin...

Abstract

The invention discloses a modified material capable of improving the structural strength of a waterproof sheet and a waterproof sheet production line capable of improving the production efficiency andthe production quality. The production line comprises a reinforcement fabric collection and storage device, a pre-impregnation device, a dip tank, a laminating device and a cooling and drying device,wherein a reinforcement fabric offset adjustment mechanism is formed on the reinforcement fabric collection and storage device through two groups of round reinforcement fabric conveying rolls, two groups of round reinforcement fabric conveying rolls on the reinforcement fabric collection and storage device comprise a round conveying roll group and a round adjusting roll group, the round conveyingroll group comprises two round conveying rolls, the round adjusting roll group comprises multiple staggered round adjusting rolls, and the diameter of each round conveying roll is larger than that ofeach round adjusting roll. The reinforcement fabric collection and storage device of the modified bituminous waterproof sheet production line is provided with a reinforcement fabric offset adjustmentrack capable of adjusting the levelness of reinforcement fabric, multiple staggered round adjusting rolls are arranged on the reinforcement fabric collection and storage device, the reinforcement fabric can be pulled up through vertically staggered and serially connected round adjusting rolls, and flatter transportation of the reinforcement fabric is ensured.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled material processing, in particular to a production process of a modified material covered on a waterproof coiled material cloth, and a production line for processing the waterproof coiled material with the modified material. Background technique [0002] Waterproof membrane is a common building material in building construction. In underground engineering and water conservancy projects, waterproof membrane can reduce leakage and withstand high water pressure; usually waterproof membrane is tire cloth (that is, waterproof membrane Structural basic fabric) is a coiled material processed by covering some other materials, and finally covered with a film (similar to a protective film) on the surface; the existing waterproof coiled material generally needs to be soaked in oil, modified Non-volatile material coating, granular material or other material coating, lamination, compaction, winding a...
