Description

Technical Field

[0001] This utility model belongs to the field of waterproof membrane technology, and in particular relates to a release membrane introduction device for producing pre-laid waterproof membranes. Background Technology

[0002] Currently, the production process of pre-laid waterproof membranes involves using polymer sheets as the surface material, laminating a layer of hot-melt butyl self-adhesive on one side of the surface material, sprinkling sand on the butyl self-adhesive according to product requirements, and finally rolling it up to form the finished pre-laid waterproof membrane. The following problems exist in the continuous production process: (1) Although the natural sand completely covers the surface of the butyl self-adhesive, some of the natural sand is unevenly distributed and has insufficient adhesion to the butyl self-adhesive, so the natural sand often falls off; (2) After the pre-laid waterproof membrane is rolled into a finished product, due to the stacking during storage and transportation, when it is opened for construction, the natural sand at the indentation point has completely penetrated into the butyl self-adhesive rubber, causing the membrane to stick together when it is unrolled for construction.

[0003] For the reasons mentioned above, the continuous production and product quality in the workshop are seriously affected: (1) After the pre-laid waterproof membrane is rolled up, the butyl self-adhesive is easy to stick to the back of the membrane, and pulling it can easily cause the butyl self-adhesive and natural sand to fall off; (2) The uneven distribution of natural sand affects the bonding ability between the pre-laid waterproof membrane and the concrete during construction; (3) The butyl self-adhesive and natural sand fall off after the slab is hardened, resulting in insufficient bonding strength between the pre-laid waterproof membrane and the concrete during construction, which increases the risk of waterproof failure in the later stage.

[0004] CN221028224U discloses a self-polymerized modified butyl rubber composite self-adhesive waterproof membrane with a metal mesh core, comprising a surface layer, a metal mesh core, a self-adhesive layer, and a release layer, which are sequentially laminated from top to bottom. The surface layer is composed of self-polymerized modified butyl rubber, and the metal mesh core is composed of metal mesh.

[0005] CN207274021U discloses a waterproof membrane comprising, from top to bottom, a gravel layer, an isolation layer, a first self-adhesive layer, a substrate, a second self-adhesive layer, and an isolation film. The lower surface of the isolation layer has several parallel, narrow channels, and small holes are spaced along these channels to connect them to the upper surface of the isolation layer. The lower surface of the first self-adhesive layer and the upper surface of the second self-adhesive layer are both covered with SBS modified bitumen. A fiberglass mesh is fixed near the bottom surface of the first self-adhesive layer. The area between the bottom surface of the fiberglass mesh and the bottom surface of the first self-adhesive layer forms a lower cover layer. The lower end of the lower cover layer has uniformly distributed adhesive protrusions.

[0021] To enable those skilled in the art to better understand and implement this patent, the markings in the accompanying drawings are explained in detail below.

[0023] Please see Figure 1 An improved pre-laid waterproof membrane comprises, from top to bottom, a release membrane layer 1, a sand layer 2, an adhesive layer 3, and a surface layer 4; in the sand layer 2, a portion of the sand is embedded within the adhesive layer 3; the improved pre-laid waterproof membrane is an integral structure.

[0024] The improved pre-laid waterproof membrane described above has a surface layer 4 made of polymer sheet.

[0025] The improved pre-laid waterproof membrane described above uses PVC, PE, EVA, TPR, or TPO as the polymer sheet.

[0026] The improved pre-laid waterproof membrane described above has an adhesive layer 3 made of butyl self-adhesive.

[0027] The improved pre-laid waterproof membrane described above has a sand layer 2 made of natural sand, manufactured sand, or a mixture of sand.

[0028] In the improved pre-laid waterproof membrane described above, the maximum dimension of the length, width, and height of the sand in the sand layer 2 is less than 0.45 mm.

[0029] The improved pre-laid waterproof membrane described above has an isolation membrane layer 1 made of PET, PTFE, or PE.

[0030] Implementation Example 1: Please see Figure 2A release liner guiding device for producing the aforementioned pre-laid waterproof membrane includes a winding machine motor, a winding machine, a traction machine motor, and upper and lower double-roller traction machines. Its features include: a release liner roll support device, an unwinding machine motor, and an automatic tensioning device; the release liner is wound onto rollers to form a release liner roll; one end of the roller is connected to the shaft of the unwinding machine motor and the automatic tensioning device; the other end of the roller is rotatably fixed to the release liner roll support device; the unwinding machine motor and the automatic tensioning device drive the release liner roll to rotate; the winding machine motor drives the winding machine to rotate; the traction machine motor drives the upper and lower double-roller traction machines to rotate; the winding machine is located in front of the upper and lower double-roller traction machines; the upper and lower double-roller traction machines are located in front of the release liner roll; the release liner roll is used to automatically unwind the release liner; the upper and lower double-roller traction machines are used to guide the release liner and the pre-laid waterproof membrane with sand, and to combine the two to form a finished pre-laid waterproof membrane; the winding machine is used to wind the finished pre-laid waterproof membrane into a roll.

[0031] In this application, an additional process is added before the pre-laid waterproof membrane is rolled up after the sand-spreading is completed. An automatic constant tension unwinding device is used to automatically unwind the rolled release film and introduce it into the pre-laid waterproof membrane, and then roll them up together to form the finished pre-laid waterproof membrane.

[0032] The unwinding machine of this device can be frequency-controlled to adjust the unwinding speed, synchronizing the supply speed of the release liner with the feed speed of the pre-laid waterproof membrane production line. A tension control system monitors and controls the tension of the release liner in real time, ensuring consistency with the tension requirements of the pre-laid waterproof membrane production process. This prevents the release liner from shrinking or folding due to tension inconsistencies between the two. With the release liner, the problem of unwinding and sticking of the pre-laid waterproof membrane is solved. Furthermore, because the tension of the release liner and the pre-laid waterproof membrane is consistent, the sand between them is evenly redistributed within their limited space during winding due to the winding force. This increases the bonding strength between the pre-laid waterproof membrane and concrete during subsequent construction, improving the product's waterproofing capability.

[0033] In summary, by using an automatic constant tension unwinding machine, the roll of release film can be automatically unwound and guided into the pre-laid waterproof membrane, which is then wound up to form the finished pre-laid waterproof membrane, effectively improving the product performance of the pre-laid waterproof membrane.
