Description

Technical Field

[0001] This application relates to the technical field of waterproof material preparation, and particularly to a preparation method and a preparation system for a double-layer composite waterproof coiled material. Background Art

[0002] In the process of building houses or factories, waterproof coiled materials are often used to achieve the waterproof function of buildings. When manufacturing waterproof coiled materials, especially double-layer composite waterproof coiled materials, usually based on a certain waterproof material layer, other film layers, such as adhesive layers, reaction sand layers, other waterproof material layers, etc., are made on both sides of the waterproof material layer. Since the waterproof material layer is a flexible thin film, when manufacturing the waterproof coiled material, it is necessary to use multiple roller structures to conduct the waterproof material layer. Therefore, when manufacturing the waterproof coiled material, generally, other film layers are sequentially laminated on one side of the waterproof material layer first, and then other film layers are sequentially laminated on the other side of the waterproof material layer. Therefore, the preparation process of the double-layer composite waterproof coiled material is usually cumbersome and requires a relatively long preparation system, increasing the production cost.

[0046] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the following detailed description, many specific details are set forth in order to provide a comprehensive understanding of the present application. However, it will be apparent to those skilled in the art that the present application can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application.

[0047] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will describe the embodiments in detail with reference to the accompanying drawings.

[0048] Relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, the elements defined by the statement "comprising..." do not exclude the presence of additional identical elements in the process, method, article or device comprising the said elements.

[0049] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "above" or "over" another layer or another region, it may mean directly above the other layer or another region, or there may be other layers or regions between it and the other layer or another region. And if the component is turned over, this layer or region will be "below" or "beneath" the other layer or region.

[0050] In addition, the term "and / or" in this document is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally represents an "or" relationship between the associated objects before and after.

[0051] It should be understood that in the embodiments of the present application, "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0052] The applicant has found that when manufacturing a double-layer composite waterproof coil, two waterproof material layers and other related film layers (such as an adhesive layer, a reactive sand layer) are laminated together. During the manufacturing process of the double-layer composite waterproof coil, usually one of the waterproof material layers is selected as the basis, and it is passed through each device for manufacturing the coil, and the other film layers are successively formed on both sides of the waterproof material layer. When the waterproof coil passes through each device for manufacturing the coil, one side of the waterproof coil contacts the roller of the device, and the device processes the other side of the waterproof coil to form a certain film layer, such as applying glue to form an adhesive layer. Therefore, each device for manufacturing the double-layer composite waterproof coil needs to be arranged in sequence to form an assembly line for manufacturing the double-layer composite waterproof coil, which is more complex than the assembly line for manufacturing a single-layer waterproof coil and will significantly increase the equipment cost. Due to the single-thread preparation process of the double-layer composite waterproof coil, the production efficiency of the double-layer composite waterproof coil is reduced.

[0053] In view of the above analysis, the applicant has proposed a method and a preparation system for manufacturing a double-layer composite waterproof coil. In the method for manufacturing the double-layer composite waterproof coil, during the process of manufacturing the first intermediate, a first adhesive layer and a reactive sand layer are successively formed on the first surface of the first material layer. The second surface of the first material layer can be used to contact the roller of some mechanisms of the preparation system, without the need to turn over the first material layer, which can simplify the manufacturing process of the double-layer composite waterproof coil. At the same time, during the process of manufacturing the second intermediate, a second adhesive layer is formed on the third surface of the second material layer. The other surface of the second material layer can contact the roller of some mechanisms of the preparation system, without the need to turn over the second material layer, which can also simplify the manufacturing process of the double-layer composite waterproof coil. Then, the second surface of the first material layer is bonded to the second adhesive layer, that is, the first intermediate and the second intermediate are bonded together to form a double-layer composite waterproof coil. The side of the second material layer facing away from the first material layer can still be used to contact the roller of some mechanisms of the preparation system, and there is no need to turn over the double-layer composite waterproof coil, which also simplifies the manufacturing process of the double-layer composite waterproof coil. By simplifying the manufacturing process of the double-layer composite waterproof coil, the method for manufacturing the double-layer composite waterproof coil according to the embodiments of the present application can improve the manufacturing efficiency of the double-layer composite waterproof coil, and at the same time reduce the complexity of the preparation system of the double-layer composite waterproof coil, and can reduce the manufacturing cost of the double-layer composite waterproof coil.

Figure 2 It is a schematic flow chart of step S1 in the method for manufacturing a double-layer composite waterproof coil according to an embodiment of the present application. Figure 3 It is a schematic structural diagram corresponding to step S1 in the method for manufacturing a double-layer composite waterproof coil according to an embodiment of the present application. Figure 4 It is a schematic flow chart of step S2 in the method for manufacturing a double-layer composite waterproof coil according to an embodiment of the present application.Figure 5 It is a schematic structural diagram corresponding to step S2 in the manufacturing method of the double-layer composite waterproof coiled material according to an embodiment of the present application.

[0055] Figure 6 It is a schematic structural diagram corresponding to step S3 in the manufacturing method of the double-layer composite waterproof coiled material according to an embodiment of the present application.

[0056] Please refer to Figures 1 to 6 , an embodiment of the present application provides a preparation method of a double-layer composite waterproof coiled material for manufacturing a double-layer composite waterproof coiled material. It should be noted that the double-layer composite coiled material should include a first material layer 11 and a second material layer 21. A first adhesive layer 13 is provided on the side of the first material layer 11 facing away from the second material layer 21 for bonding the reaction sand layer 15, and the first material layer 11 and the second material layer 21 are bonded through a second adhesive layer 23.

[0057] Continue to refer to Figure 1 , the preparation method of the double-layer composite waterproof coiled material according to an embodiment of the present application includes:

[0058] Step S1, manufacturing a first intermediate 1, including:

[0059] Continue to refer to Figure 2 and Figure 3 , step S11, releasing the first material layer 11.

[0060] The first material layer 11 is released in a strip form. Exemplarily, the first material layer 11 can be in a rolled state before being released, and the first material layer 11 is drawn out from the first material layer coil 12.

[0061] Continue to refer to Figure 2 and Figure 3 , step S12, manufacturing the first adhesive layer 13.

[0062] The released strip-shaped first material layer 11 has opposite first and second surfaces, and the first adhesive layer 13 is manufactured on the first surface of the first material layer 11. Exemplarily, the first adhesive layer 13 can be manufactured by applying glue. It can be understood that when manufacturing the first adhesive layer 13, the first material layer 11 can be horizontally arranged with the first surface facing vertically upward to reduce the possibility of the applied glue dripping from the first surface and to form a flat first adhesive layer 13.

[0063] Continue to refer to Figure 2 and Figure 3 , step S13, manufacturing the reaction sand layer 15.

[0064] Place the reactive sand on the side of the first adhesive layer 13 away from the first material layer 11. The first adhesive layer 13 bonds the reactive sand, and the bonded reactive sand will not easily peel off from the first adhesive layer 13, forming a reflective sand layer. It can be understood that when manufacturing the reactive sand layer 15, the first material layer 11 can be set horizontally with the first surface facing vertically upward to reduce the reactive sand from evenly covering the first surface to form a flat reactive sand layer 15.

[0065] Steps S11 to S13 are equivalent to sequentially manufacturing the first adhesive layer 13 and the reactive sand layer 15 on the first surface of the first material layer 11, which can be regarded as the processing process of the first material layer 11, that is, the manufacturing process of the first intermediate 1. During this process, no film layer is manufactured on the second surface of the first material layer 11, which can be used to contact the transfer rollers of each device used in steps S11 to S13 to facilitate the transfer of the first material layer 11.

[0066] Continue to refer to Figure 1 , the preparation method of the double-layer composite waterproof coiled material according to the embodiment of the present application further includes:

[0067] Step S2, manufacturing the second intermediate 2, includes:

[0068] Continue to refer to Figure 4 and Figure 5 , step S21, releasing the second material layer 21.

[0069] The second material layer 21 is released in a strip form. Exemplarily, the second material layer 21 can be in a rolled form before being released, and the second material layer 21 is drawn out from the second material layer coil 22.

[0070] Step S22, manufacturing the second adhesive layer 23.

[0071] The released strip-shaped second material layer 21 has opposite third and fourth surfaces, and the second adhesive layer 23 is manufactured on the third surface of the second material layer 21. Exemplarily, the second adhesive layer 23 can be manufactured by applying glue. It can be understood that when manufacturing the second adhesive layer 23, the second material layer 21 can be set horizontally with the third surface facing vertically upward to reduce the possibility of the applied glue dripping from the third surface to form a flat second adhesive layer 23.

[0072] Steps S21 to S22 can be regarded as the processing process of the second material layer 21, that is, the manufacturing process of the second intermediate 2. During the process of steps S21 to S22, no film layer is manufactured on the fourth surface of the second material layer 21, which can be used to contact the transfer rollers of each device used in steps S21 to S22 to facilitate the transfer of the second material layer 21.

[0073] Step S1 and step S2 are carried out synchronously, that is to say, the first intermediate 1 and the second intermediate 2 are produced simultaneously. It can be understood that at this time, the second surface of the first material layer 11 in the first intermediate 1 faces the second adhesive layer 23 in the second intermediate 2.

[0074] Continue to refer to Figure 1 and Figure 6 , the preparation method of the double-layer composite waterproof coiled material according to the embodiment of the present application further includes:

[0075] Step S3, bond the first intermediate 1 and the second intermediate 2.

[0076] In view of the fact that the second surface of the first material layer 11 in the first intermediate 1 faces the second adhesive layer 23 in the second intermediate 2, the first intermediate 1 and the second intermediate 2 can be directly pressed together to obtain the double-layer composite waterproof coiled material.

[0077] In the embodiment of the present application, since the first intermediate 1 and the second intermediate 2 are produced synchronously and then bonded together to form the double-layer composite waterproof coiled material, the production efficiency of the double-layer composite waterproof coiled material can be improved. In addition, the production of the first intermediate 1 and the production of the second intermediate 2 form a two-thread process, which reduces the production difficulty and saves the production cost of the double-layer composite waterproof coiled material.

[0078] Figure 7 It is another process schematic diagram of step S1 in the production method of the double-layer composite waterproof coiled material according to the embodiment of the present application. Figure 8 It is another process schematic diagram of step S2 in the production method of the double-layer composite waterproof coiled material according to the embodiment of the present application. Figure 9 It is another structural schematic diagram corresponding to step S3 in the production method of the double-layer composite waterproof coiled material according to the embodiment of the present application.

[0079] Further, please refer to Figures 7 to 9 , the second surface includes a first bonding area A11, the third surface includes a second bonding area A21, and the first bonding area A11 and the second bonding area A21 correspond to both sides of the second adhesive layer 23.

[0080] Step S22 includes: making the second adhesive layer 23 in the second bonding area A21 of the second material layer 21. Exemplarily, the second adhesive layer 23 can be made by means of coating. It should be noted that in the area outside the second bonding area A21, the adhesive liquid can be applied or not.

[0081] Step S3 includes: adjusting the relative positions of the first intermediate 1 and the second intermediate 2 so that the orthographic projection of the first bonding area A11 on the second surface overlaps with the orthographic projection of the second bonding area A21 on the second surface. That is to say, the first bonding area A11 and the second bonding area A21 are aligned. Press the first intermediate 1 and the second intermediate 2 together, bond the second surface of the first material layer 11 and the side of the second adhesive layer 23 facing away from the second material layer 21, and bond the first intermediate 1 and the second intermediate 2 together to form a double-layer composite waterproof coiled material.

[0082] Further, continue to refer to Figures 7 to 9 , the second surface further includes a first overlapping area A12. After the production of the double-layer composite waterproof coiled material is completed, the first overlapping area A12 corresponds to the overlapping edge of the double-layer composite waterproof, so as to facilitate overlapping multiple cut composite waterproof coiled materials together.

[0083] After step S13, step S1 further includes:

[0084] Step S14, producing a first overlapping adhesive layer 14.

[0085] In the first overlapping area A12, produce a first overlapping adhesive layer 14. Exemplarily, the second adhesive layer 23 can be produced by applying glue. It should be noted that after step S13, the side of the reaction sand layer 15 facing away from the first material layer 11 can bear a certain external force. Therefore, in step S14, the first overlapping adhesive layer 14 can be produced on the second surface of the first material layer 11. At this time, the side of the reaction sand layer 15 facing away from the first material layer 11 is in contact with the conveying roller of the equipment. In addition, after producing the first overlapping adhesive layer 14, on the side of the first overlapping adhesive layer 14 facing away from the first material layer 11, an isolation edge film should also be produced. The isolation edge film covers the first overlapping adhesive layer 14 to reduce the risk of the first overlapping adhesive layer 14 sticking back. When splicing multiple double-layer composite waterproof coiled materials, the isolation edge film can be removed so that the first overlapping adhesive layer 14 is in an exposed state for bonding with other double-layer composite waterproof coiled materials.

[0086] Step S3 further includes: adjusting the relative positions of the first intermediate 1 and the second intermediate 2 so that the orthographic projection of the first bonding area A11 on the second surface overlaps with the orthographic projection of the second bonding area A21 on the second surface. That is to say, the first bonding area A11 and the second bonding area A21 are aligned. At this time, it is also necessary to expose the first overlapping adhesive layer 14 to the second material layer 21. That is to say, the second intermediate 2 should not cover the position of the first overlapping area A12.

[0087] Further, continue to refer to Figures 7 to 9, the third surface further includes a second overlapping area A22. After the production of the double-layer composite waterproof coiled material is completed, the second overlapping area A22 corresponds to another overlapping edge of the double-layer composite waterproofing. When multiple cut composite waterproof coiled materials are overlapped, the overlapping edges corresponding to the first overlapping area A12 and the overlapping edges corresponding to the second overlapping area A22 can be bonded together.

[0088] Step S22 further includes: in the second overlapping area A22, a second overlapping adhesive layer 24 is made. The second overlapping adhesive layer 24 and the second adhesive layer 23 can be made synchronously. When making the second overlapping adhesive layer 24, an isolation edge film should also be made on the side of the second overlapping adhesive layer 24 away from the second material layer 21, and the second overlapping adhesive layer 24 is covered by the isolation edge film. When splicing multiple double-layer composite waterproof coiled materials, the isolation edge film needs to be removed so that the second overlapping adhesive layer 24 is in an exposed state for bonding with other double-layer composite waterproof coiled materials.

[0089] Step S3 includes: adjusting the relative positions of the first intermediate 1 and the second intermediate 2 so that the orthographic projection of the first bonding area A11 on the second surface overlaps with the orthographic projection of the second bonding area A21 on the second surface. That is to say, the first bonding area A11 and the second bonding area A21 are aligned. At this time, it is also necessary to expose the second overlapping adhesive layer 24 to the first material layer 11. That is to say, the first intermediate 1 should not cover the position of the second overlapping area A22.

[0090] Figure 10 It is a schematic flow diagram of step S13 in the manufacturing method of the double-layer composite waterproof coiled material according to the embodiment of the present application.

[0091] Further, please refer to Figure 10 , step S13 includes:

[0092] Step S131: Set reaction sand.

[0093] Place an excessive amount of reaction sand on the side of the first adhesive layer 13 away from the first material layer 11. The amount of reaction sand used needs to exceed the amount of reaction sand required to cover the first adhesive layer 13 completely, so as to enable the reaction sand to cover all positions of the first adhesive layer 13.

[0094] Step S132: Lay the reaction sand.

[0095] The reaction sand can be evenly spread over the side of the first adhesive layer 13 away from the first material layer 11 by sweeping or scraping the reaction sand. Except for the excess reaction sand, the reaction sand covering the first adhesive layer 13 is initially bonded to the first adhesive layer 13.

[0096] Step S133: Recover the reaction sand.

[0097] Since an excessive amount of reaction sand is used in step S131, a part of the reaction sand is not bonded to the first adhesive layer 13. At this time, this excess reaction sand can be recycled, and the recycled reaction sand can be reused in step S131. Therefore, in the embodiments of the present application, the preparation cost of the double-layer composite waterproof coil can be reduced.

[0098] Step S134, sand kneading treatment.

[0099] After recycling the excess reaction sand, the remaining reaction sand is the reaction sand bonded to the first adhesive layer 13. Kneading this part of the reaction sand can make the bonding between the reaction sand and the first adhesive layer 13 more firm and form a flat reaction sand layer.

[0100] Figure 11 It is a schematic flow diagram of step S11 in the manufacturing method of the double-layer composite waterproof coil according to the embodiments of the present application.

[0101] Further, please refer to Figure 11 , step S11 includes:

[0102] Step S111, extracting the first material layer 11.

[0103] The first material layer 11 is loaded in the form of the first material layer coil 12, and the first material layer 11 can be extracted from the first material layer coil 12 through a conveyor roller or a traction device.

[0104] Step S112, temporarily storing the first material layer 11.

[0105] In step S111, an excessive amount of the first material layer 11 can be extracted from the first material layer coil 12, and this part of the first material layer 11 can be temporarily stored.

[0106] Step S113, replacing the first material layer coil 12.

[0107] When all the first material layer 11 in a coil of the first material layer 11 is extracted, the temporarily stored first material layer 11 can be released. At the same time, a new first material layer coil 12 is replaced. When the temporarily stored first material layer 11 is released, the first material layer 11 can continue to be extracted from the newly replaced first material layer coil 12. In the process of continuously manufacturing the double-layer composite waterproof coil, steps S111 to S113 can be repeated, so that in step S11, the state of releasing the first material layer 11 can always be maintained to adapt to the continuous production of the double-layer composite waterproof coil and improve the production efficiency.

[0108] Considering the equipment required to temporarily store the first material layer 11 in step S112, steps S111 to S113 are applicable to the preparation environment of the double-layer composite waterproof coil with sufficient space.

[0109] Figure 12 Another process schematic diagram of step S11 in the manufacturing method of the double-layer composite waterproof coiled material according to the embodiment of the present application.

[0110] Optionally, please refer to Figure 12 , step S11 includes:

[0111] Step S111: Set at least two coils 12 of the first material layer.

[0112] The axes of the at least two coils 12 of the first material layer are arranged in parallel and the ends are aligned. Any one of the multiple coils 12 of the first material layer can be used for feeding the first material layer 11.

[0113] Step S112: Extract the first material layer 11.

[0114] Extract the first material layer 11 from one of the coils 12 of the first material layer. The first material layer 11 can be extracted from the coil 12 of the first material layer by a conveying roller or a traction device.

[0115] Step S113: Replace the coil 12 of the first material layer.

[0116] When all the first material layer 11 in the coil 12 of the first material layer has been extracted, the first material layer 11 can continue to be extracted from the next coil 12 of the first material layer. At this time, the coil 12 of the first material layer from which the first material layer 11 has been completely extracted can be replaced. During the continuous manufacturing process of the double-layer composite waterproof coiled material, steps S112 to S113 can be repeated so that in step S11, the state of releasing the first material layer 11 can always be maintained to adapt to the continuous production and manufacturing of the double-layer composite waterproof coiled material and improve the manufacturing efficiency.

[0117] When replacing the coil 12 of the first material layer from which the first material layer 11 has been completely extracted, the coil 12 of the first material layer can be moved axially along the coil 12 of the first material layer to avoid interference with the extraction of the first material layer 11 when replacing the coil 12 of the first material layer. Considering that steps S111 to S113 do not require equipment for temporarily storing the first material layer 11, and when replacing the coil 12 of the first material layer, the coil 12 of the first material layer to be replaced moves along its axis to facilitate the replacement of the coil 12 of the first material layer, so steps S111 to S113 are applicable to the preparation environment of the double-layer composite waterproof coiled material with limited space.

[0118] Figure 13 A process schematic diagram of step S21 in the manufacturing method of the double-layer composite waterproof coiled material according to the embodiment of the present application.

[0119] Further, please refer to Figure 13, Step S21 is similar to Step S11. Step S21 includes:

[0120] Step S211, extract the second material layer 21.

[0121] The second material layer 21 is loaded in the form of the second material layer coil 22. The second material layer 21 can be extracted from the second material layer coil 22 through conveying rollers or traction equipment.

[0122] Step S212, temporarily store the second material layer 21.

[0123] In Step S211, part of the second material layer 21 can be extracted excessively from the second material layer coil 22, and this part of the second material layer 21 is temporarily stored.

[0124] Step S213, replace the second material layer coil 22.

[0125] When all the second material layers 21 in a coil of the second material layer 21 are extracted, the temporarily stored second material layer 21 can be released. At the same time, a new second material layer coil 22 is replaced. After the temporarily stored second material layer 21 is released, the second material layer 21 can continue to be extracted from the newly replaced second material layer coil 22. During the continuous production of the double-layer composite waterproof coil, Steps S211 to S213 can be repeated, so that in Step S21, the state of releasing the second material layer 21 can always be maintained to adapt to the continuous production of the double-layer composite waterproof coil and improve the production efficiency.

[0126] Considering the equipment for temporarily storing the second material layer 21 in Step S212, Steps S211 to S213 are applicable to the preparation environment of the double-layer composite waterproof coil with sufficient space.

[0127] Figure 14 Another process schematic diagram of Step S21 in the manufacturing method of the double-layer composite waterproof coil according to the embodiment of the present application.

[0128] Optionally, please refer to Figure 14 , Step S21 includes:

[0129] Step S211, set at least two second material layer coils 22.

[0130] The axes of at least two second material layer coils 22 are arranged in parallel and the ends are aligned. Any one of the second material layer coils 22 among the multiple second material layer coils 22 can be used for loading the second material layer 21.

[0131] Step S212, extract the second material layer 21.

[0132] The second material layer 21 can be drawn out from one of the second material layer coils 22, and the second material layer 21 can be drawn out from the second material layer coil 22 by a conveying roller or a traction device.

[0133] Step S213: Replace the second material layer coil 22.

[0134] When all of the second material layer 21 in the second material layer coil 22 has been drawn out, the second material layer 21 can continue to be drawn out from the next second material layer coil 22. At this time, the second material layer coil 22 from which the second material layer 21 has been completely drawn out can be replaced. During the continuous production of the double-layer composite waterproof coiled material, steps S212 to S213 can be repeated so that in step S21, the state of releasing the second material layer 21 can always be maintained to adapt to the continuous production of the double-layer composite waterproof coiled material and improve the production efficiency.

[0135] When replacing the second material layer coil 22 from which the second material layer 21 has been completely drawn out, the second material layer coil 22 can be moved along the axial direction of the second material layer coil 22 to avoid interference with the drawing out of the second material layer 21 when replacing the second material layer coil 22. Considering that steps S211 to S213 do not require equipment for temporarily storing the second material layer 21, and when replacing the second material layer coil 22, the second material layer coil 22 to be replaced is moved along its axis to facilitate the replacement of the second material layer coil 22, so steps S211 to S213 are applicable to the preparation environment of the double-layer composite waterproof coiled material with limited space.

[0136] Figure 15 FIG. is a schematic structural diagram of a manufacturing system for the double-layer composite waterproof coiled material according to an embodiment of the present application. Figure 16 FIG. is another schematic structural diagram of a manufacturing system for the double-layer composite waterproof coiled material according to an embodiment of the present application.

[0137] Please refer to Figure 15 and Figure 16 . An embodiment of the present application also provides a preparation system for a double-layer composite waterproof coiled material, which uses the preparation method of the double-layer composite waterproof coiled material in the foregoing embodiment of the present application to prepare the double-layer composite waterproof coiled material.

[0138] The preparation system of the double-layer composite waterproof coiled material according to the embodiment of the present application includes: a first preparation mechanism 100 for preparing a first intermediate 1. The first preparation mechanism 100 includes a first unwinding and deviation rectifying component 110, a first gluing component 120, and a sand covering component 140.

The second unwinding and deviation rectifying component 210 is used to release a second material layer 21. The second gluing component 220 is arranged downstream of the second unwinding and deviation rectifying component 210, and the second gluing component 220 is used to make a second glue layer 23 on the third surface of the second material layer 21. A traction and deviation rectifying mechanism 300 is arranged downstream of the first preparation mechanism 100 and downstream of the second preparation mechanism 200. The traction and deviation rectifying mechanism 300 is used to bond the first intermediate 1 and the second intermediate 2.

[0139] The first preparation mechanism 100 is used to prepare the first intermediate 1. The first material layer 11 will be conveyed within the first preparation mechanism 100 to form an assembly line. Based on the conveying direction of the first material layer 11, the side closer to the initial direction of conveyance is the upstream, and the side closer to the destination direction of conveyance is the downstream. The first unwinding and deviation rectifying component 110 can release the first material layer 11. In addition, it can also adjust the position of the first material layer 11 so that the first material layer 11 can be conveyed to the first gluing component 120 at an accurate angle and direction. The first gluing component 120 is arranged downstream of the first unwinding and deviation rectifying component 110, and the first gluing component 120 is used to make the first glue layer 13 on the first surface of the first material layer 11. Exemplarily, the first gluing component 120 may include a gluing device. The sand covering component 140 is arranged downstream of the first gluing component 120, and the sand covering component 140 is used to make the reactive sand layer 15 on the side of the first glue layer 13 facing away from the first material layer 11. Exemplarily, the sand covering component 140 includes a sand covering device, a recovery device, and a sand kneading device. The sand covering device is used to place excessive reactive sand on the side of the first glue layer 13 facing away from the first material layer 11. The recovery device is used to recover the excess reactive sand. The sand kneading device is used to knead the reactive sand to make the bonding between the reactive sand and the first glue layer 13 more firm and form a flat reactive sand layer. After the reactive sand layer 15 is made, the first intermediate 1 can be obtained.

[0140] The second preparation mechanism 200 is used to prepare the first intermediate 1. The second material layer 21 is conveyed within the second preparation mechanism 200 to form an assembly line. Based on the conveying direction of the second material layer 21, the side closer to the initial direction of conveyance is the upstream, and the side closer to the destination direction of conveyance is the downstream. The second unwinding and deviation rectifying assembly 210 can release the second material layer 21 and, in addition, can adjust the position of the second material layer 21 so that the second material layer 21 can be conveyed to the second gluing assembly 220 at an accurate angle and direction. The second gluing assembly 220 is arranged downstream of the second unwinding and deviation rectifying assembly 210, and the second gluing assembly 220 is used to form the second glue layer 23 on the third surface of the second material layer 21. Exemplarily, the second gluing assembly 220 may include a gluing device. After the second glue layer 23 is formed, the second intermediate 2 can be obtained.

[0141] The traction and deviation rectifying mechanism 300 is simultaneously arranged downstream of the first preparation mechanism 100 and downstream of the second preparation mechanism 200. By traction of the first intermediate 1 and the second intermediate 2, the first intermediate 1 and the second intermediate 2 are bonded together. During this process, the traction and deviation rectifying mechanism 300 can also adjust the relative positions and angles of the first intermediate 1 and the second intermediate 2 so that the first intermediate 1 and the second intermediate 2 can be aligned and bonded to form a double-layer composite waterproof coiled material. It can be understood that the obtained double-layer composite waterproof coiled material can be wound into a coil by the winding mechanism 400.

[0142] By simplifying the preparation method of the double-layer composite waterproof coiled material, the preparation system of the double-layer composite waterproof coiled material in the embodiments of the present application can be simplified, thereby reducing the production cost of the double-layer composite waterproof coiled material.

[0143] Figure 17 It is another structural schematic diagram of the manufacturing system of the double-layer composite waterproof coiled material in the embodiments of the present application. Figure 18 It is another structural schematic diagram of the manufacturing system of the double-layer composite waterproof coiled material in the embodiments of the present application.

[0144] It should be noted that please refer to Figure 17 and Figure 18, for the preparation system of single-layer waterproof coiled materials in the related art, it includes various devices of the first preparation mechanism 100, and in addition, it will also include other devices. It is possible to use the preparation system of single-layer waterproof coiled materials as part of the preparation system of the double-layer composite waterproof coiled materials in the embodiments of the present application, so as to reduce the construction cost of the preparation system of the double-layer composite waterproof coiled materials in the embodiments of the present application. When using the preparation system of the double-layer composite waterproof coiled materials in the embodiments of the present application, the redundant devices in the original preparation system of single-layer waterproof coiled materials can be suspended, that is, which devices are required by the preparation system of the double-layer composite waterproof coiled materials in the embodiments of the present application will operate. Exemplarily, when the preparation system of the double-layer composite waterproof coiled materials in the embodiments of the present application uses a set of preparation system of single-layer waterproof coiled materials, the first preparation mechanism 100 and the traction and deviation correction mechanism 300 can continue to use some devices in the preparation system of single-layer waterproof coiled materials. Among them, the film covering device in the preparation system of single-layer waterproof coiled materials can be suspended. When building the preparation system of the double-layer composite waterproof coiled materials in the embodiments of the present application, only the second preparation mechanism 200 needs to be additionally set; or, when the preparation system of the double-layer composite waterproof coiled materials in the embodiments of the present application uses two sets of preparation systems of single-layer waterproof coiled materials, the first preparation mechanism 100 can continue to use some devices in a set of preparation system of single-layer waterproof coiled materials. Among them, the film covering device, the traction device and the winding device in the preparation system of single-layer waterproof coiled materials can be suspended. The second preparation mechanism 200 and the traction and deviation correction mechanism 300 can continue to use some devices in a set of preparation system of single-layer waterproof coiled materials. Among them, the film covering device, the sand covering device and the sand kneading device in the preparation system of single-layer waterproof coiled materials can be suspended. When building the preparation system of the double-layer composite waterproof coiled materials in the embodiments of the present application, the two sets of preparation systems of single-layer waterproof coiled materials can be respectively arranged on two floors. By continuing to use the preparation system of single-layer waterproof coiled materials, even in the case of partial redundancy of devices, the construction cost of the preparation system of the double-layer composite waterproof coiled materials in the embodiments of the present application can be greatly reduced, thereby reducing the production cost of the double-layer composite waterproof coiled materials.

[0145] Further, continue to refer to Figures 15 to 18 , the second surface includes a first overlapping area A12 and a first bonding area A11; the first preparation mechanism 100 further includes a first side film assembly 130. The first side film assembly 130 is arranged downstream of the sand covering assembly 140, and the first side film assembly 130 is used to make a first overlapping adhesive layer 14 in the first overlapping area A12.

[0146] The first side film assembly 130 is disposed downstream of the sand-covered assembly 140. The first side film assembly 130 is used to fabricate a first lap adhesive layer 14 in the first lap zone A12 and fabricate an isolation side film on the side of the first lap adhesive layer 14 away from the first adhesive layer 13. The second glue coating assembly 220 is used to fabricate a second adhesive layer 23 in the second bonding zone A21. When bonding the second adhesive layer 23 and the second surface, align the first bonding zone A11 and the second bonding zone A21 so that the first bonding zone A11 and the second bonding zone A21 are bonded through the second adhesive layer 23. Meanwhile, the first lap adhesive layer 14 is covered by the isolation side film and is relatively exposed together with the second adhesive layer 23. When splicing multiple double-layer composite waterproof coiled materials, the first lap adhesive layer 14 can be used for bonding. During bonding, the isolation side film needs to be removed so that the first lap adhesive layer 14 is exposed for bonding with other double-layer composite waterproof coiled materials.

[0147] Further, continue to refer to Figures 15 to 18 , the third surface includes a second lap zone A22 and a second bonding zone A21; the second glue coating assembly 220 is further used to fabricate a second lap adhesive layer 24 in the second lap zone A22.

[0148] The second glue coating assembly 220 simultaneously applies glue in the second lap zone A22 and the second bonding zone A21 to form a second adhesive layer 23 and a second lap adhesive layer 24, and fabricates an isolation side film on the side of the second lap adhesive layer 24 away from the second material layer 21. When bonding the second adhesive layer 23 and the second surface, align the first bonding zone A11 and the second bonding zone A21 so that the first bonding zone A11 and the second bonding zone A21 are bonded through the second adhesive layer 23. Meanwhile, the second lap adhesive layer 24 is covered by the isolation side film and the two are relatively exposed together with the second adhesive layer 23. When splicing multiple double-layer composite waterproof coiled materials, the second lap adhesive layer 24 can be used for bonding. During bonding, the isolation side film needs to be removed so that the second lap adhesive layer 24 is exposed for bonding with other double-layer composite waterproof coiled materials.

[0149] It can be understood that the double-layer composite waterproof coiled materials fabricated by the preparation system of the double-layer composite waterproof coiled materials in the embodiments of the present application can simultaneously have a first lap adhesive layer 14 and a second lap adhesive layer 24. When splicing multiple double-layer composite waterproof coiled materials, after removing the isolation side films of the first lap adhesive layer 14 and the second lap adhesive layer 24 respectively, the first lap adhesive layer 14 and the second lap adhesive layer 24 can be bonded together.

[0150] Figure 19 It is a schematic structural diagram of a first unwinding and deviation rectifying component of the manufacturing system of the double-layer composite waterproof coiled materials in the embodiments of the present application.

[0151] Further, please refer to Figure 19, the first unwind deviation rectifying assembly 110 includes a first unwind discharging device 111 and a first storage device 112. The first unwind discharging device 111 is used for detachably installing the first material layer coil 12. The first storage device 112 is arranged downstream of the first storage device 112, and the first storage device 112 can store a part of the first material layer 11.

[0152] The first unwind discharging device 111 can be a hydraulic lifting unwinder to extract the first material layer 11 from the first material layer coil 12. A part of the extracted first material layer 11 will be temporarily stored in the first storage device 112. The first storage device 112 can be an unwind storage rack. The first material layer 11 is conveyed in a serpentine manner in the unwind storage rack. By lengthening or shortening the length of the serpentine shape, the temporary storage or release of the first material layer 11 is achieved. When all the first material layer 11 in the first material layer coil 12 is extracted, the first storage device 112 releases the first material layer 11 temporarily stored therein. During this process, the first material layer coil 12 in the first unwind discharging device 111 can be replaced, so that the unwind discharging device can always maintain the state of releasing the first material layer 11, thereby replacing the first material layer coil 12 without pausing the preparation system of the double-layer composite waterproof coiled material in the embodiment of the present application, which is beneficial to the continuous production of the double-layer composite waterproof coiled material and improves the preparation efficiency.

[0153] Figure 20 It is another structural schematic diagram of the first unwind deviation rectifying assembly of the double-layer composite waterproof coiled material manufacturing system in the embodiment of the present application.

[0154] Optionally, please refer to Figure 20 , the first unwind deviation rectifying assembly 110 includes at least two first unwind discharging devices 111. The first unwind discharging devices 111 are used for detachably installing the first material layer coils 12. The first unwind discharging devices 111 are movably arranged along a direction parallel to their own axes. The axes of at least two first unwind discharging devices 111 are parallel and the ends are aligned.

[0155] The first unwind deviation rectifying component 110 can be a multi-station unwind deviation rectifying device, and each station corresponds to a first unwind discharging device 111. In this embodiment of the application, the case where the first unwind deviation rectifying component 110 is a double-station unwind deviation rectifying device is taken as an example for illustration. When the first material layer 11 of the first material layer 11 coil of one station is completely drawn out, the first material layer 11 can continue to be drawn out from the first material layer 11 coil of another station. At this time, move the first unwind discharging device 111 along the axial direction of the first material layer coil 12, and replace the first material layer coil 12 in the first unwind discharging device 111 without affecting the release of the first material layer 11 of another station, so as to replace the first material layer coil 12 without pausing the preparation system of the double-layer composite waterproof coil in this embodiment of the application, which is beneficial to the continuous production of the double-layer composite waterproof coil and improves the preparation efficiency.

[0156] Figure 21 It is a schematic structural diagram of a second unwind deviation rectifying component of the production system of the double-layer composite waterproof coil in this embodiment of the application.

[0157] Further, please refer to Figure 21 , the second unwind deviation rectifying component 210 includes a second unwind discharging device 211 and a second storage device 212. The second unwind discharging device 211 is used for detachably installing the second material layer coil 22. The second storage device 212 is arranged downstream of the second storage device 212, and the second storage device 212 can store a part of the second material layer 21.

[0158] The second unwind discharging device 211 can be a hydraulic lifting unwind machine to draw out the second material layer 21 from the second material layer coil 22. A part of the drawn second material layer 21 will be temporarily stored in the second storage device 212. The second storage device 212 can be an unwind storage rack, and the second material layer 21 is conveyed in the unwind storage rack in a snake shape. By lengthening or shortening the length of the snake shape, the temporary storage or release of the second material layer 21 is realized. When all the second material layer 21 in the second material layer coil 22 is drawn out, the second storage device 212 releases the second material layer 21 temporarily stored therein. During this process, the second material layer coil 22 in the second unwind discharging device 211 can be replaced, so that the unwind discharging device can always keep the state of releasing the second material layer 21, thereby replacing the second material layer coil 22 without pausing the preparation system of the double-layer composite waterproof coil in this embodiment of the application, which is beneficial to the continuous production of the double-layer composite waterproof coil and improves the preparation efficiency.

[0159] Figure 22 It is another schematic structural diagram of a second unwind deviation rectifying component of the production system of the double-layer composite waterproof coil in this embodiment of the application.

[0160] Optionally, please refer to Figure 22, the second unwind deviation rectifying assembly 210 includes at least two second unwind discharging devices 211. The second unwind discharging device 211 is used for detachably installing the second material layer coil 22. The second unwind discharging device 211 is movably arranged along a direction parallel to its own axis. The axes of at least two second unwind discharging devices 211 are arranged in parallel and the ends are aligned.

[0161] The second unwind deviation rectifying assembly 210 can be a multi-station unwind deviation rectifying device, and each station corresponds to a second unwind discharging device 211. In the embodiment of the present application, the second unwind deviation rectifying assembly 210 is taken as an example of a two-station unwind deviation rectifying device for illustration. When the second material layer 21 of the second material layer coil 22 at one station is completely drawn out, the second material layer 21 can continue to be drawn out from the second material layer coil 22 at another station. At this time, move the second unwind discharging device 211 along the axial direction of the second material layer coil 22, and replace the second material layer coil 22 in the second unwind discharging device 211 on the premise of not affecting the release of the second material layer 21 at another station, so as to replace the second material layer coil 22 without pausing the preparation system of the double-layer composite waterproof coil in the embodiment of the present application, which is beneficial to the continuous production of the double-layer composite waterproof coil and improves the preparation efficiency.

[0162] In summary, there is provided a method and a preparation system for a double-layer composite waterproof coil according to an embodiment of the present application. In the method for preparing the double-layer composite waterproof coil, during the process of manufacturing the first intermediate body, a first adhesive layer and a reflective sand layer are sequentially formed on the first surface of the first material layer. The second surface of the first material layer can be used to contact the rollers of some mechanisms of the preparation system, and there is no need to turn over the first material layer, which can simplify the preparation process of the double-layer composite waterproof coil. At the same time, during the process of manufacturing the second intermediate body, a second adhesive layer is formed on the third surface of the second material layer. The other surface of the second material layer can contact the rollers of some mechanisms of the preparation system, and there is no need to turn over the second material layer, which can also simplify the preparation process of the double-layer composite waterproof coil. Then, bond the second surface of the first material layer to the second adhesive layer, that is, bond the first intermediate body and the second intermediate body to form a double-layer composite waterproof coil. The side of the second material layer facing away from the first material layer can still be used to contact the rollers of some mechanisms of the preparation system, and there is no need to turn over the double-layer composite waterproof coil, which also simplifies the preparation process of the double-layer composite waterproof coil. By simplifying the preparation process of the double-layer composite waterproof coil, the method for preparing the double-layer composite waterproof coil according to the embodiment of the present application can improve the preparation efficiency of the double-layer composite waterproof coil, and at the same time reduce the complexity of the preparation system of the double-layer composite waterproof coil, and can reduce the preparation cost of the double-layer composite waterproof coil.
