[0006] Composite waterproof membranes often have a three-layer or four-layer structure. The production process is more complicated than that of the homogeneous type, and the equipment forms are also quite different.

The existing composite process is often completed in a step-by-step composite method. The first layer is composited with the composite material layer (second layer), and then the second layer is composited with the third and fourth layers of materials after molding. And get the final product, increase the production process and cost of the product, and the composite ...

Abstract

The invention creates and provides a multilayer waterproof roll for a composite internal-enhancing fabric and a production process thereof. The multilayer waterproof roll comprises a surface layer, aninternal-enhancing fabric layer, a back layer and a back-lining layer which are sequentially adhered from top to bottom, wherein the surface layer and the back layer are high molecular material layers, the internal-enhancing fabric layer is polyester gridding cloth, and the back-lining layer is polyester fiber cloth. Multiple layers of the multilayer waterproof roll can be composited by virtue ofa three-roll calender through a synchronous composite process, so that the compositing strength among composite layers can be furthest guaranteed; and the strength of the multilayer waterproof roll is mainly supplied by the internal-enhancing polyester gridding cloth in the use process, and the applicability is supplied by the back-lining layer, so that the mutual complementation of the advantages and disadvantages of reinforcing ribs and back linings is realized.

Example Embodiment

[0031] Example 1 (coil)

[0032] Such as figure 1 As shown, this embodiment provides a multi-layer waterproof roll material 100 of composite inner reinforcing fabric, which includes a surface layer 101, an inner reinforcing fabric layer 102, a backing layer 103, and a backing layer 104 that are sequentially bonded from top to bottom. The surface layer 101 and the back layer 103 are both main material layers, and the main material can be a polymer material. Generally, resins are commonly used, such as thermoplastic resins such as chlorinated polyethylene and polyvinyl chloride.

[0033] Wherein, the inner reinforcing fabric layer 102 is a polyester mesh cloth.

[0034] Wherein, the backing layer 104 is polyester fiber cloth.

[0035] During use, the multi-layer waterproof membrane of the composite inner reinforced fabric mainly relies on the inner reinforcement mesh to provide strength, and the backing layer 104 provides applicability. Therefore, the multi-layer waterproof membrane 100 can be rolled in accordance with the national standard P type. The performance requirements of the material are evaluated. Taking the surface layer 101 and the back layer 103 using polyvinyl chloride as an example, the material performance of the multilayer waterproof membrane 100 in this embodiment meets the requirements shown in Table 1:

Example Embodiment

[0038] Example 2 (coil laying method)

[0039] According to the multi-layer waterproof coiled material 100 of composite inner reinforced fabric provided in embodiment 1, when laying the multi-layer waterproof coiled material 100 in this embodiment, the construction method of the backing type waterproof coiled material can be referred to: The waterproof coiled material of the backing is laid according to the full-adhesive construction method, which has the characteristics of fast construction, safety, and strong bonding. The concrete laying steps of the multilayer waterproof membrane 100 are as follows:

[0040] (1) Clean the surface of the base layer before construction, ensure that the surface is clean, and confirm that the surface of the base layer is smooth and free of oil and other pollution;

[0041] (2) When applying adhesive, the elastic line should be measured, and the adhesive should be applied according to the reference line, and the application should be even and smooth;

[0042] (3) The steel structure roof can be coated with adhesive and then the coil is laid. The coil backing layer 104 is directly bonded to the adhesive layer; for the concrete roof, the coil with the backing is directly laid on the uncured concrete surface , So that the backing layer 104 is embedded in the concrete to form full adhesion. It is best to measure the elastic line during installation and lay the construction according to the reference line;

[0043] When laying the coiled material, the backing layer 104 faces downwards. If a curing adhesive is used for coating, in order to prevent too fast curing, you can lay the coiled material while painting. Pay attention to the thickness of the coating; if you use a non-curing adhesive Adhesive can fold the coil in half, first paste half of the coil, pay attention to aligning the overlap edge, and then paste the other half of the coil;

[0044] (4) After construction, the large surface is compacted with a silicone pressure roller to ensure that the large surface is not hollowed or wrinkled.

[0045] After the laying is completed, in the process of the coiled material exerting its waterproof function, the external force will be affected by the wind, vibration and artificial application. At this time, the fully adhesive backing layer 104 is equivalent to having countless stress points to uniform the external force. Dispersed on the coil, reducing the possibility of coil damage. At the same time, there is a polyester mesh cloth as a reinforcing layer inside the coil, and the external force will be absorbed by the mesh cloth. The mesh cloth itself is much stronger than the main material, and it is wrapped by the main material, so it is not easy to deteriorate the mechanical properties due to aging. , So that the coil can achieve durability and long-term waterproof effect.

[0046] The following are further improvements to this embodiment:

[0047] In order to ensure the bonding effect when the coil is fully adhered to the concrete base surface, after the base layer is cleaned, you can also use the JS waterproof coating stock solution to mix with water, mix and stir at a ratio of 1:19, and then use the roller brush to perform on the base layer. Coat evenly to increase the adhesion of the base layer, then apply the adhesive and lay the waterproof membrane.

[0048] Example 3 (production process)

[0049] reference figure 2 The production process of the multi-layer waterproof coiled material of composite inner reinforced fabric provided by the present invention is as follows:

[0050] (1) The back layer 103 and the surface layer 101 of the product are respectively formed by the first molding die 201 and the second molding die 202, and the product back layer 103 and the surface layer 101 can be made of resin materials;

[0051] (2) The composite inner reinforcing fabric layer 102 (fiber material, such as polyester mesh cloth can be used) is inserted from the middle of the two forming molds through the first unwinding device 203 above the forming mold to form an intermediate layer, Under the traction force of the three-roll calender 205, the back layer 103, the surface layer 101 and the inserted intermediate layer formed from the molding die are compressed between the two rollers of the three-roll calender 205;

[0052] (3) The backing layer 104 is made of fiber material (may be polyester fiber cloth), which passes through the second unwinding device 204 and the first guide roller 206 and then enters between the two rollers of the three-roll calender 205, and the step (2 The process described in) simultaneously completes the compression, one-time composite molding, and then passes through the second guide roller 207 to cool naturally to become the final multilayer waterproof membrane 100.

[0053] When the resin melt flowing out of the forming mold enters the gap between the two rolls of the three-roll calender 205, the time it stays in the air is extremely short, and the temperature of the resin layer is basically close to the forming temperature in the forming mold. , The melt can maintain good viscoelasticity, the surface layer resin can be completely integrated with the back layer resin through the gap of the composite fiber material, and the composite strength is high.

[0054] For the products produced by the synchronous composite process in this embodiment, they have been tested in accordance with relevant waterproof membrane testing standards, and their material properties all meet the performance parameters of backing waterproof membranes using the same main material, and their tensile properties and connection The seam peel strength exceeds the requirements of national standards: the excellent interlayer composite strength improves the seam peel strength of the product.
