Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of waterproof building materials, in particular to a waterproof coiled material for pipeline sealing. Background Art
[0002] Waterproof membranes have many uses, such as walls, roofs, bathroom floors, etc. In addition, they are also used for vertical or pipe waterproofing. However, since the construction site is often dusty, when the workers stick the self-adhesive tape on the waterproof membrane, it is not easy to stick firmly due to the adsorption of dust; in addition, since the construction site is generally uneven, it is not easy to flatten the self-adhesive tape on the waterproof membrane, so it is not beautiful after construction; in addition, for larger diameter pipes, such as the main outdoor tap water pipes and gas pipes, a larger overlap is required. There is basically no wide self-adhesive tape on the market, so it needs to be pasted multiple times. Even for generally used pipes, due to their long length, the speed of pasting the self-adhesive tape on site is very slow, which affects the construction efficiency. For this reason, construction workers and users hope to have a new type of waterproof membrane for pipe sealing that can be quickly constructed. Utility Model Content

[0026] The above-mentioned waterproof roll material for pipeline sealing is characterized in that the width of the second anti-adhesion layer 7 is 20mm-100mm.
[0027] Please see Figure 5 , and refer to Figures 1 to 4 The above-mentioned waterproof membrane for sealing pipes is used, for example, to seal pipes at indoor corners, usually PVC pipes, etc., which are vertical, such as sewage outlet pipes, water pipes, etc. Although they have a certain thickness, they are relatively brittle. When hard objects collide intentionally or unintentionally, they will break or crack the pipes, which will cause unnecessary troubles. For this reason, objects are usually used to protect the pipes during or after decoration. When the waterproof membrane of the present application is used, the required length can be cut from the waterproof membrane that is several tens of meters long. The first adhesive layer 5 and the second adhesive layer 7 are torn off, so that the second adhesive layer 4 and the third adhesive layer 6 are bonded to each other. This bonding is more firm. At the same time, since the first adhesive layer 5, the second adhesive layer 7, the second adhesive layer 4 and the third adhesive layer 6 are produced at the time of production, they match the corresponding widths and are flatly shaped during production. Therefore, compared with the construction of items such as self-adhesive tapes, the construction speed is improved and the product is flatter and smoother; the overlap 8 formed at the bonding point is more beautiful, Figure 5 The figure is only for illustration, and the actual overlap is inside, which effectively protects. In the implementation example, the two separated third bonding outer layers 61 and third bonding inner layers 62 make the bonding at the overlap more reliable after bonding. If liquid or gas penetrates, it can also be buffered in the gap between the third bonding outer layer 61 and the third bonding inner layer 62, which has a better sealing seal. Generally, after the waterproof roll is bonded, some impact and collision-proof buffer materials are additionally coated on the outside, so that better protection can be obtained. In addition, there are also rectangular or square partitions formed on the outside, which can better protect.
[0028] In this application, it can also be used for the external sealing of horizontal pipelines. Whether it is vertical sealing or horizontal sealing, it can effectively and further protect the pipeline, and it can also be used as a temporary pipeline when liquid or gas penetrates.
[0029] In the present application, after production is completed, the first anti-adhesive layer 5 completely covers the second adhesive layer 4 , and similarly, the second anti-adhesive layer 7 completely covers the third adhesive layer 6 .
[0030] Compared with the prior art, in the present application, the second adhesive layer 4, the first anti-adhesive layer 5, the third adhesive layer 6, and the second anti-adhesive layer 7 are integrated on the waterproof membrane, which solves the problems of uneven and irregular self-adhesive tape at the construction site, slow construction speed, and low efficiency. At the same time, it avoids the problem that the self-adhesive is not firmly adhered or easily falls off after the waterproof membrane is filled with dust or is covered with dust at the construction site with a lot of dust.
[0031] Therefore, the present application has the following main beneficial technical effects: simple structure, easy manufacturing, beautiful appearance after being coated on the pipeline, smoother and firmer bonding, and higher construction efficiency.
[0032] The above embodiments are only preferred technical solutions of the present utility model and should not be regarded as limitations of the present utility model. The protection scope of the present utility model shall be the technical solution recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solution recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present utility model.
