Problems solved by technology

[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

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...

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; ...

Example Embodiment

[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 lay...

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.

Description

technical field [0001] The invention belongs to the field of building material industry, and in particular relates to an improved waterproof coiled material. Background technique [0002] At present, the more common waterproof membranes in polymer waterproof membranes are classified according to the material composition: H type (homogeneous), P type (reinforced), L type (backing), G type (glass fiber), GL type Class (glass fiber backing), among which Class H, Class P and Class L have a high usage rate due to their outstanding advantages. [0003] The P-type membrane is the reinforced internally reinforced waterproof membrane, which uses polyester fiber fabric (grid type) as the reinforcement layer. Through a special extrusion process, the main material such as double-sided PVC or TPO and the middle polyester fiber The fabric reinforcement layer is combined into one polymer waterproof membrane. During the production process, the reinforcing rib is fully bonded to the membra...
