[0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist the seepage of external rainwater and groundwater. As a leak-free connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project.

[0003] After the waterproofing membranes are laid, the bonding points between the waterproofing membranes need to be heated and bonded. Currently, the bonding points between the waterproofing membranes are heated and bonded by workers holding a baking device, which is dangerous, unsafe, and unevenly heated, resulting in poor bonding effect. Summary of the invention

[0004] In view of this, the present invention provides a waterproof membrane and a construction method thereof, aiming to improve the problems of poor bonding effect and unsafe construction of existing waterproof membranes.

[0006] The first connection portion is connected to the second connection portion of the adjacent waterproof coiled material, and the second connection portion is connected to the first connection portion of the adjacent waterproof coiled material;

[0007] The first connecting portion comprises a first substrate, at least two slots provided on the first substrate, and a groove provided between two adjacent slots; the second connecting portion comprises a second substrate, at least two plug-in portions provided on the second substrate, and a protrusion provided between two adjacent plug-in portions; the slots and the grooves have depth directions parallel to the thickness direction of the coil body; the slots are matched and connected with the stopper of the plug-in portion, and the grooves are matched and connected with the stopper of the protrusion;

[0008] An adhesive layer is provided between the bottom of the groove and the top surface of the protrusion, and the adhesive layer is a structural layer formed by electromagnetic induction welding of a metal dense mesh and an adhesive.

[0014] In a second aspect, the present invention provides a construction method of a waterproof roll material, which is applied to the waterproof roll material provided in the first aspect of the present invention, comprising the following steps:

[0015] Step 1: Clean and pre-treat the laying base surface;

[0016] Step 2: laying a plurality of the waterproof rolls and attaching them to the laying base surface, wherein epoxy resin adhesive and curing agent are poured into the groove in a weight ratio of 10:3 and stirred to mix, the plug-in portion is inserted into the slot and the protrusion is inserted into the groove, so that the first connection portion of the waterproof roll is connected to the second connection portion of the adjacent waterproof roll;

[0017] Step three: using a magnetic field transformer to heat the connection between the groove and the protrusion, so that the first connection part and the second connection part are bonded together.

[0039] Please refer to Figures 1 to 4The embodiment of the present invention provides a waterproof coiled material, including a coiled material body 1, wherein the coiled material body 1 is provided with a first connection portion and / or a second connection portion; the first connection portion is connected to the second connection portion of an adjacent waterproof coiled material, and the second connection portion is connected to the first connection portion of an adjacent waterproof coiled material; the first connection portion includes a first substrate 4, at least two slots 5 provided on the first substrate 4, and a groove 6 provided between two adjacent slots 5, the second connection portion includes a second substrate 7, at least two plug-in portions 8 provided on the second substrate 7, and a protrusion 9 provided between two adjacent plug-in portions 8, the groove depth directions of the slots 5 and the grooves 6 are both parallel to the thickness direction of the coiled material body 1, the slots 5 are matched with the stoppers of the plug-in portions 8, and the grooves 6 are matched with the stoppers of the protrusions 9; an adhesive layer 11 is provided between the bottom of the groove 6 and the top surface of the protrusion 9, and the adhesive layer 11 is a structural layer formed by electromagnetic induction welding of a metal dense mesh 10 and an adhesive.

[0040] It should be understood that the coil body 1 can be a polygonal shape such as a rectangle or a triangle, or a circular, annular or other shape with a curved edge structure, and the embodiment of the present application is not limited to the shape of the waterproof coil. In addition, the waterproof coil is a planar structural member, that is, the waterproof coil is a structural member whose thickness dimension is much smaller than its surface dimension. In general, the first connecting portion and the second connecting portion are both located at a position of the coil body 1 close to the edge of one side of the adjacent coil body 1.

[0041] In specific implementation, the roll body 1 is provided with a first connection part and / or a second connection part, which means that the roll body 1 is provided with a first connection part, or the roll body 1 is provided with a second connection part, or the roll body 1 is provided with a first connection part and a second connection part. Taking a plurality of waterproof rolls laid in sequence along the left and right straight lines as an example, the waterproof roll in the middle has a first connection part provided near the left edge of its roll body 1, and the first connection part is used to connect with the second connection part of the adjacent waterproof roll; the waterproof roll in the middle has a second connection part provided near the right edge of its roll body 1, and the second connection part is used to connect with the first connection part of the adjacent waterproof roll; and the waterproof roll on the far left has a second connection part provided on the right edge of its roll body 1, and the second connection part is used to connect with the first connection part of the adjacent waterproof roll. There is no adjacent waterproof roll on the left side of the waterproof roll on the far left, so it does not need to be provided with a first connection part; similarly, the waterproof roll on the far right does not need to be provided with a second connection part. In addition, see Figure 1 The number of the first connection part and the second connection part of the same waterproof coiled material can be one or more. In specific implementation, the number of the first connection part and the second connection part should be designed according to actual needs.

[0042] It should be understood that the slot 5 is connected with the stopper of the plug-in portion 8, and the groove 6 is connected with the stopper of the protrusion 9, which means that the position, shape and size of the slot 5 can match the position, shape and size of the plug-in portion 8, and the position, shape and size of the groove 6 can match the position, shape and size of the protrusion 9. Among them, because the position of the slot 5 matches the position of the plug-in portion 8, the notch of the slot 5 and the plug-in portion 8 should be located on the side of two adjacent waterproof membranes close to each other.

[0043] In a specific implementation, a metal dense mesh 10 is provided on the bottom of the groove 6 and / or the top surface of the protrusion 9 .

[0044] In the waterproof coiled material provided in the present embodiment, before electromagnetic induction welding, the groove 6 can be used as a cavity for the adhesive, the plug-in portion 8 is inserted into the slot 5, and the protrusion 9 is inserted into the groove 6, so that the first connection portion of the waterproof coiled material is connected to the second connection portion of the adjacent waterproof coiled material, and the connection between the first connection portion and the second connection portion is a detachable connection; during the electromagnetic induction welding process, the metal dense mesh 10 generates current and heat due to the change of magnetic flux, and the adhesive receives this part of the heat, and the adhesive melts and mixes, and a chemical reaction occurs and generates a large amount of heat, so that the temperature at the gap between the groove 6 and the protrusion 9 is as high as the melting point of the metal dense mesh 10, so that the hot metal dense mesh 10 melts into liquid, and the liquid metal dense mesh 10 is melted into liquid. The reactants of the mesh and the adhesive are integrated into one, and the heat is evenly dispersed, filling the gap between the bottom of the groove 6 and the top surface of the protrusion 9. The liquid metal dense mesh and the reactants of the adhesive form an adhesive layer 11 together after cooling and solidifying, thereby achieving adhesion between the first substrate 4 and the second substrate 7. The liquid metal dense mesh increases the strength of the adhesive layer 11. The adhesive layer 11 has strong viscosity and high hardness, and has reliable and stable performance, so that the gaps between adjacent waterproof membranes are completely filled, and the leakage path between adjacent waterproof membranes is blocked, with a reliable adhesion effect. In addition, the connection construction process of the waterproof membrane provided in this embodiment does not require the staff to hold a high-temperature baking device, which can ensure the safety of the staff.

[0045] In some embodiments, the metal mesh 10 is made of a tin-lead alloy material.

[0046] In some embodiments, the bonding agent includes an adhesive and a fixing agent.

[0047] In some embodiments, the curing agent is an aliphatic amine curing agent. Specifically, the curing agent includes ethylenediamine and / or diethylenetriamine.

[0048] In some embodiments, the roll body 1 is integrally formed with the first substrate 4, the second substrate 7, the plug-in portion 8 and the protruding portion 9. This facilitates the preparation of the waterproof roll and is beneficial to the structural strength of the waterproof roll.

[0049] The construction method of the waterproof membrane provided in any of the above embodiments comprises the following steps:

[0050] Step 1: Clean and pre-treat the laying base surface;

[0051] Step 2: Lay a plurality of waterproof rolls and attach them to the laying base surface, wherein epoxy resin adhesive and curing agent are poured into the groove 6 at a weight ratio of 10:3 and stirred and mixed, the plug-in portion 8 is inserted into the slot 5 and the protrusion 9 is inserted into the groove 6, so that the first connection portion of the waterproof roll is connected to the second connection portion of the adjacent waterproof roll;

[0052] Step 3: Use a magnetic field transformer to heat the connection between the groove 6 and the protrusion 9, so that the first connection part and the second connection part are bonded together.

[0053] In some embodiments, pre-processing the paving base surface in step one includes: detecting defects on the paving base surface, filling or chiseling the detected defects; and performing rounding treatment on the inside and outside corners and pipe root parts of the paving base surface.

[0054] In the construction method of the waterproof coiled material provided in this embodiment, the magnetic field transformer causes the change of the magnetic flux of the metal dense mesh 10 to generate current and generate heat, reaching the temperature required for the chemical reaction of the epoxy resin adhesive and the curing agent. The epoxy resin adhesive and the curing agent melt to form a mixture, and chemically react to form a cross-linked structure. At the same time, a large amount of heat is generated, so that the temperature at the gap between the groove 6 and the protrusion 9 is as high as the melting point of the metal dense mesh 10, so that the hot metal dense mesh 10 melts into a liquid state, and the liquid metal dense mesh and the reactant of the adhesive are integrated into one, filling the groove. The gap between the bottom of the groove 6 and the top surface of the protrusion 9, the liquid metal dense mesh and the reaction product of the adhesive form a bonding layer 11 after being cooled and solidified. The liquid metal dense mesh 10 melts into the cross-linked structure to increase the strength of the bonding layer 11, and the heat is evenly dispersed. The bonding layer 11 fills the gap between the groove 6 and the protrusion 9; the bonding layer 11 has strong viscosity, high hardness, reliable and stable performance, and adheres the first connection part and the second connection part together, so that there is no gap between the two adjacent waterproof coils, blocking the leakage path and improving the waterproof effect of the waterproof coil. In addition, in the construction method of the waterproof coil, there is no need for the staff to hold a high-temperature baking device, which can ensure the safety of the staff.

It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
