Description

Technical Field

[0001] The invention belongs to the technical field of waterproof coiled materials, and in particular relates to a production line of waterproof coiled materials. Background Art

[0002] Waterproofing membrane is a commonly used building material in construction. In the construction of roads, bridges, roofs or buildings that need waterproofing, waterproofing membranes need to be laid in advance. According to its main waterproofing components, it can be divided into three categories: asphalt waterproofing materials, polymer modified waterproofing membranes and synthetic polymer waterproofing membranes. Among them, asphalt waterproofing membranes are the most commonly used waterproofing membranes, accounting for 70% of the total market. This kind of membrane is a rollable sheet waterproofing material made by dipping asphalt on the base and then spreading powdered or flaky isolation materials on the surface. Traditional oxidized asphalt has many defects such as limited temperature range of use, which greatly limits the use of asphalt waterproofing membranes.

[0003] For example, the patent application number CN201510140604.0 discloses a production process of a polymer modified asphalt waterproofing membrane, which includes the following steps: Step 1: Mix the polymer modifier and antioxidant evenly and add them to the feeding device of the main extruder. The temperature of the feeding section of the main extruder is 140-185℃.

[0004] Step 2: Freeze and crush the asphalt, add plasticizer or add plasticizer, tackifying resin, interfacial reaction agent and asphalt to mix, gradually add filler after mixing evenly and stir again; add the mixture to the feeding device of the auxiliary extruder, and the temperature range of the auxiliary extruder is 60-185℃. Step 3: Start the main extruder. When the polymer modifier in the main extruder is plasticized and reaches the melting section of the main extruder, start the auxiliary extruder. The front end of the melting section is provided with a kneading block and a reverse thread, and the end of the melting section is provided with a vacuum exhaust. The auxiliary extruder extrude the plasticized asphalt molten blend into the end of the feeding section of the main extruder. Step 4: Cooling of polymer modified asphalt: The polymer modified asphalt passes through the cooling section of the main extruder, and the temperature gradually drops from 185-200°C to 80-120°C. A vacuum exhaust is provided at the end of the cooling section.

[0005] Step 5: The polymer modified asphalt enters the screen changing section and is coated onto the waterproof membrane substrate through a flat die head. Step 6: Compound the isolation protection layer on the surface of the polymer modified asphalt by means of a pressure roller.

[0006] For example, the patent with application number CN201120164038.4 discloses a one-time forming production line for wide self-adhesive polymer composite waterproofing membrane, which is composed of a screw, an extrusion die, two geotextile unwinding devices, three calendering rollers, two storage elastic racks, a modified asphalt coating device, a self-adhesive layer laminating roller, a separation film unwinding device, a rolling device, etc.; the arrangement and installation order of each production device on the production line is: screw, extrusion die, geotextile unwinding device, three calendering rollers, geotextile unwinding device, storage elastic rack, modified asphalt coating device, self-adhesive layer laminating roller, separation film unwinding device, storage elastic rack, rolling device. The separation film unwinding device is located above the self-adhesive layer laminating roller and after the modified asphalt coating device. The separation film is covered on the modified asphalt self-adhesive layer through the self-adhesive layer laminating roller, which is conducive to the subsequent rolling device to roll the product into a roll.
