Description

Technical Field

[0001] The invention belongs to the field of building waterproofing, and in particular relates to a waterproofing coiled material suitable for side walls, top plates and roofs of underground projects. Background Art

[0002] During the construction of building waterproofing, after the waterproofing membrane is laid, it is usually necessary to apply a protective layer on the waterproofing membrane, such as a fine stone concrete protective layer, cement, etc., to prevent the subsequent construction of steel bars or backfill soil from squeezing, puncturing, and other damage to the waterproofing membrane, or to block the influence of the external environment such as direct sunlight, delay the aging of the waterproof layer during use, and extend the service life of the membrane. At the same time, in order to avoid the volume stress caused by deformation and cracking of the protective layer to damage the waterproofing membrane, it is also necessary to set up an isolation layer between the waterproofing membrane and the protective layer in flat parts such as the top plate of the basement, such as using geotextiles or mortar, etc., and the protective layer is constructed after the isolation layer is completed on the surface of the waterproofing membrane. The isolation layer will increase the waterproofing construction process and extend the construction period, increase the construction cost, and is often neglected by the construction unit during the construction process. The isolation layer is not made according to the requirements and specifications, which has a greater impact on the waterproofing performance in the later stage. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide a waterproof isolation protection integrated waterproof roll material with its own isolation layer, so that no additional isolation layer is required during construction.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A waterproof isolation protection integrated waterproof roll material comprises at least one intermediate tire base layer, rubber layers respectively compounded on both sides of the tire base layer, and isolation membranes respectively coated on the outermost sides of the rubber layers, wherein the isolation membrane on one side is a conventional isolation membrane, and the other side is a thickened isolation membrane, and the thickness of the thickened isolation membrane is greater than that of the conventional isolation membrane.

[0006] The outer surface of the thickened isolation membrane is coated with silicone oil.

[0007] Both sides of the thickened isolation film are coated with silicone oil.

[0008] The thickness of the thickened isolation film ranges from 0.3 mm to 0.6 mm.

[0009] The thickness of the thickened isolation film is preferably 0.4 mm.

[0010] The thickened isolation film can be made of PE, PET or PP plastic film.

[0011] The tire base layer is provided with two layers, and the rubber layer is provided with three layers. The rubber layers are respectively compounded on both sides of each tire base layer. The material of the tire base layer can be any one or two of PE film, PET film, TPO film, PVC film, EPDM film, polyethylene polypropylene film, woven cloth or metal aluminum foil.

[0012] After adopting the above technical solution, the present invention has the following advantages compared with the background technology:

[0013] 1. When the waterproofing membrane of the present invention is used on a flat surface such as a roof, the thickened isolation membrane can replace the original isolation layer. After the isolation membrane has a certain thickness, it can achieve the same impact resistance and puncture resistance. Therefore, there is no need to set up an additional isolation layer during construction. After the membrane is paved, a protective layer can be directly constructed on top, which reduces the structural layer, shortens the construction period, and reduces the overall cost.

[0014] 2. When the waterproof membrane of the present invention is constructed on the side wall, the silicone oil coated on the surface of the outermost thickened isolation membrane is relatively smooth and has a small friction resistance. Therefore, the destructive tension of the waterproof membrane caused by the sinking of backfill soil can be reduced, and the waterproof layer can be prevented from being pulled off. The thickened isolation membrane plays a certain isolation and protection role.

[0015] 3. Because the thickened isolation membrane is used as an isolation layer and a functional layer, the generation of construction waste is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Example 1

[0024] See also Figure 1 As shown, the present invention discloses an integrated waterproof membrane for isolation and protection, comprising a middle layer of a base layer 1, a rubber layer 2 compounded on both sides of the base layer 1, and isolation membranes respectively coated on the outermost layers on both sides.

[0025] The isolation membrane on one side is a conventional isolation membrane 3, and the other side is a thickened isolation membrane 4, that is, the thickness of the thickened isolation membrane 4 is greater than the thickness of the conventional isolation membrane 3 used on the other side.

[0026] The thickness of the conventional separator 3 is generally 0.02 mm, and the thickness of the thickened separator 4 of this embodiment is 0.6 mm, and a PE (polyethylene) plastic film is used. The tire base layer 1 can be made of a core-skin composite long fiber tear-resistant cloth.

[0027] The isolation film is used to protect the internal rubber layer 2 from being polluted by external dust and oil stains, and also prevents the coils from sticking to each other when they are packaged into rolls. The inner surface of the conventional isolation film 3 in contact with the rubber layer 2 is coated with a layer of silicone oil, while the thickened isolation film 4 is coated with a layer of silicone oil on both sides.

[0028] Silicone oil has good anti-stick properties and is used to prevent adhesion between coil layers during production, processing, storage and transportation. It also facilitates the peeling of the isolation film and the rubber layer during construction.

[0029] The construction diagram of the present invention used in the side wall 10 is shown in FIG. Figure 2 As shown, the waterproof membrane is wet-laid on the outer side of the concrete side wall 10. During construction, a layer of cement slurry is sprayed on the surface of the side wall 1, and the conventional isolation membrane 3 on one side of the waterproof membrane is removed. The rubber layer 2 on the inner side contacts and reacts with the cement slurry. During the cement curing process, a tight bonding interface layer 6 is formed through the synergistic effect of chemical crosslinking and physical mortise and tenon (Chemical Bonding and Physical Crosslinking Synergism, referred to as CPS, see the applicant's previously authorized patent ZL200910114456.X for details).

[0030] After the waterproofing membrane is laid, backfilling is performed, and the outer side of the thickened isolation membrane 4 is backfilled with soil 7 or sand.

[0031] Since the outer surface of the thickened isolation membrane 4 is coated with a layer of silicone oil, which is hydrophobic and has a small surface tension, and the silicone oil coating is relatively slippery, it can prevent the transmission of the downward pulling force of the backfill soil, avoid the cracking of the waterproof membrane caused by the downward pulling force, and play a protective role on the waterproof membrane.

[0032] The construction diagram of the present invention used in the top plate 8 is shown in Figure 3 As shown, the waterproofing membrane is wet-laid on the top plate 8, that is, a layer of cement slurry is sprayed first, the conventional isolation membrane 3 of the waterproofing membrane is removed, and the rubber layer 2 on the inner side contacts the cement slurry to produce a CPS reaction to form a bonding interface layer 6. After the paving is completed, a protective layer 9 is constructed on the upper surface of the waterproofing membrane. The thickened isolation membrane 4 on the uppermost surface of the membrane is equivalent to the isolation layer originally provided between the protective layer 9 and the membrane, so there is no need to provide an additional isolation layer.

[0033] Example 2

[0034] The waterproof isolation protection integrated waterproof coiled material provided in this embodiment includes a middle layer of a base layer 1, a rubber layer 2 compounded on both sides of the base layer 1, and an isolation membrane respectively coated on the outermost layers on both sides.

[0035] The isolation film on one side is a conventional isolation film 3, and the other side is a thickened isolation film 4. The thickened isolation film 4 of this embodiment is made of PET (polyethylene terephthalate) plastic film with a thickness of 0.4 mm.

[0036] Example 3

[0037] The waterproof isolation protection integrated waterproof coiled material provided in this embodiment includes a middle layer of a base layer 1, a rubber layer 2 compounded on both sides of the base layer 1, and an isolation membrane respectively coated on the outermost layers on both sides.

[0038] The isolation film on one side is a conventional isolation film 3, and the other side is a thickened isolation film 4. The thickened isolation film 4 of this embodiment is made of PP (polypropylene) plastic film with a thickness of 0.3 mm.

[0039] The present invention selects waterproof rolls with thickened isolation membranes of 0.2 mm, 0.7 mm, and 0.8 mm in thickness as comparative examples 1 to 3. The performance test results of the waterproof roll samples of embodiments 1 to 3 and comparative examples 1 to 3 are as follows:

[0040]

[0041]

[0042] Considering the comprehensive protection effect and product construction conformability, the preferred thickness of the thick isolation film is 0.4 mm.

[0043] In addition to the above embodiments, the present invention also provides another form of waterproof roll material, wherein the thickened isolation film 4 is the same as the conventional isolation film 3, and during the production process, the silicone oil 5 is only applied on the inner surface in contact with the rubber layer 2. During construction, the thickened isolation film 4 is peeled off from the outer side of the rubber layer 2 and then reversely adhered, so that the silicone oil originally on the inner surface is turned to the outside, forming a Figure 4 Of course, it is also possible not to perform anti-sticking, and the friction of the backfill soil can be reduced by using the smooth nature of the isolation membrane itself, but the isolation and protection effect is not as good as the form of coating the surface with silicone oil.

[0044] Figure 4 The structure can be formed by bonding the thickened isolation film 4 in reverse during construction, or it can be directly produced and prepared. Figure 4 The thickened isolation film 4 is in the form of a coil, that is, only the outer surface of the thickened isolation film 4 in the production process is coated with silicone oil, and there is no silicone oil on the inner surface of the side in contact with the rubber layer 2. The thickened isolation film 4 is directly compounded with the rubber layer 2 to form an inseparable whole.

[0045] The present invention also provides another form of waterproof roll material, see Figure 5 As shown, the waterproof coiled material is provided with two layers of tread base layers 1 and three layers of rubber layers 2, the rubber layers 2 are respectively compounded on both sides of the tread base layer 1, the conventional isolation film 3 and the thickened isolation film 4 are respectively coated on the outermost layers on both sides, the material of the tread base layer 1 can be one of PE film, PET film, TPO film, PVC film, EPDM film, polyethylene polypropylene film, woven cloth or metal aluminum foil, and the two layers of tread base layers 1 can be selected from the above different materials or the same material.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
