Description

Technical Field

[0001] The invention relates to the field of waterproofing coiled material technology, in particular to a butyl rubber elastomer composite polymer self-adhesive waterproofing coiled material and equipment. Background Art

[0002] Self-adhesive waterproof membranes are widely used in roofing, underground and indoor projects of various types of buildings, as well as waterproofing projects such as open-cut subways, tunnels, pools, canals, and pipe galleries. They are especially suitable for waterproofing projects where open flames are not allowed.

[0003] The existing self-adhesive waterproof membrane can refer to the patent document with publication number CN116904122A. The above patent document discloses a self-adhesive waterproof membrane, which is provided with an adhesion-promoting coating. By designing the coating formula and coating pattern, the bonding strength at the overlapping edges of the membrane is improved and the risk of water leakage at the overlapping edges is reduced.

[0004] However, since the mechanical strength of the outermost polymer membrane is low, it is easily scratched by steel components or construction equipment during roof construction, which has an adverse effect on the waterproof performance. Usually, a concrete protective layer is set above the waterproof membrane to separate the steel bars from the waterproof membrane, thereby increasing the pouring and curing time of the protective layer. Summary of the invention

[0005] In order to shorten the construction period of roof waterproofing and improve the waterproof performance of the roll material, the present application provides a butyl rubber elastomer composite polymer self-adhesive waterproof roll material and equipment.

[0006] On the one hand, the present application provides a butyl rubber elastomer composite polymer self-adhesive waterproof roll material, which adopts the following technical solution:

[0007] A butyl rubber elastomer composite polymer self-adhesive waterproofing membrane, used for pre-laying construction, comprising:

[0008] The self-adhesive sealing layer has one or more layers of alloy laminated films on its upper surface.

[0009] By adopting the above technical solution, the alloy laminated film is covered on the upper surface of the self-adhesive sealing layer of the waterproof coiled material, and the advantages of high mechanical strength of metal are utilized to improve the puncture resistance and tear resistance of the waterproof coiled material, and improve the ductility, so that the setting of the protective layer can be eliminated, and steel bars can be laid directly on the waterproof coiled material and concrete can be poured, thereby shortening the construction period of the roof waterproofing and reducing the damage to the waterproof coiled material caused by the construction;

[0010] The laminated film made of alloy also has good waterproof and water-proof properties;

[0011] In addition, the alloy laminated film has high density and mechanical strength. Under the action of its own weight, it can make the surface of the coil smoother and can also be used as a bottom form for concrete, so that the thickness of the poured concrete is more uniform.

[0012] Since concrete has poor ductility and is prone to cracking, rainwater is prone to leaking after cracking. Casting the alloy laminated membrane and reinforced concrete together can also improve the ductility of the concrete layer, enhance the durability of the roofing method, and further improve the waterproof performance.

[0013] Furthermore, the self-adhesive sealing layer is provided with a first burr, the alloy laminate film is provided with a second burr, the first burr and the second burr are interlaced with each other, and adhesive is filled between the first burr and the second burr.

[0014] By adopting the above technical scheme, the contact surfaces of the self-adhesive sealing layer and the alloy laminated film are both roughened, the first burrs and the second burrs are interlaced with each other to increase the contact area, and adhesive is filled in the gap. The physical mortise and tenon joints and the chemical bonding reaction work synergistically to improve the bonding strength between the alloy laminated film and the self-adhesive sealing layer.

[0015] Furthermore, the adhesive composition includes butyl rubber and a tackifier.

[0016] By adopting the above technical solution, butyl rubber has excellent sealing performance, but its adhesion is weak. Adding a tackifier can improve the sealing performance while maintaining the viscosity.

[0017] Furthermore, the self-adhesive sealing layer includes a polymer waterproof layer, a self-adhesive layer and a release film from top to bottom.

[0018] By adopting the above technical solution, the waterproof ability of the roll material is further improved by the combined effect of the polymer waterproof layer and the alloy laminated film; the release film can play an isolating role when the waterproof roll material is in a roll shape.

[0019] Furthermore, the self-adhesive layer is made of butyl rubber.

[0020] By adopting the above technical solution, the self-adhesive layer also adopts butyl rubber, which further improves the anti-seepage performance of the roll material.

[0021] Furthermore, an overlapping edge is left at the edge of a single piece of the waterproof coiled material, and the overlapping edge shares the alloy laminated film with the remaining part. Within the range of the overlapping edge, the self-adhesive sealing layer is covered on top of the alloy laminated film.

[0022] By adopting the above technical solution, since the surface of the alloy laminated film is smooth and hydrophobic, if the upper and lower layers are directly overlapped without changing the overlap edge layer structure arrangement, the self-adhesive sealing layer is bonded to the smooth alloy laminated film, and rainwater can easily penetrate along the edge of the roll. The layer structure arrangement of the waterproof roll within the overlap edge range is symmetrically distributed with the alloy laminated film as the axis, the self-adhesive sealing layer has a strong creep performance, and the self-adhesive sealing layer of the overlap edge and the self-adhesive sealing layer of the adjacent roll are bonded to each other, which can minimize the gap between the two layers of waterproof rolls and improve the waterproof ability at the overlap edge; in addition, the reversal of the material sorting can also serve as a mark for the overlap edge range, making it easier for workers to align the overlap edge during construction, making the joints between the two rolls more neat and beautiful, thereby improving the paving quality of the waterproof roll.

[0023] Furthermore, the upper surface of the alloy laminate film is covered with an anti-corrosion coating.

[0024] By adopting the above technical solution, since the roof is in an outdoor environment and is easily corroded by rainwater and microorganisms, the anti-corrosion coating can protect the alloy laminated film.

[0025] On the other hand, the present application provides a construction device for a butyl rubber elastomer composite polymer self-adhesive waterproof membrane, which adopts the following technical solution:

[0026] A butyl rubber elastomer composite polymer self-adhesive waterproof roll material, comprising:

[0027] A fuselage, wherein a rotating shaft is fixed to the bottom of the fuselage, and a gripping portion is provided at one end of the fuselage away from the rotating shaft;

[0028] A pressure roller, rotatably connected to the rotating shaft, an abutment member convexly provided on the end surface of the pressure roller;

[0029] The nail gun comprises a gun body and a pressure rod, one end of the pressure rod is hinged to the gun body, the gun body is fixedly connected to the fuselage, the gun body is provided with a downward nail outlet, the abutment member presses the end of the pressure rod away from the hinge point to drive the gun body to fire the nail outward;

[0030] The bottom of the gun body is flush with the bottom of the pressure roller, and both are in contact with the waterproof coiled material.

[0031] By adopting the above technical solution, during roof construction, after laying the waterproofing membrane, the worker pushes the machine body and uses the pressure roller to roll over the waterproofing membrane. After pressing, the internal structure of the waterproofing membrane and the adhesion between the waterproofing membrane and the roof panel can be made tighter. Improving the density of the membrane is also conducive to improving the waterproof performance. A nail gun is set, and the rotation of the pressure roller drives the abutment to make a circular motion. The pressure rod of the nail gun blocks the movement path of the abutment. During the downward movement of the abutment, the abutment gradually presses and presses the pressure rod, and the nail outlet downward shoots nails to the waterproofing membrane, further improving the connection strength between the waterproofing membrane and the roof panel, and preventing the membrane from warping and displacement.

[0032] Therefore, the pressure roller can be linked with the nail gun so that the rolling of the coiled material and the laying of the nails can be carried out simultaneously, which is conducive to shortening the construction period and speeding up the construction efficiency.

[0033] Furthermore, the pressure roller is a stone roller or a steel roller.

[0034] By adopting the above technical solution, the stone and steel have a large dead weight, and using stone rollers or steel rollers to roll the waterproof membrane can achieve better results.

[0035] Furthermore, the abutment member is matched with the pressure rod in a concave-convex manner, and the abutment member is rotatably connected to the pressure roller.

[0036] By adopting the above technical solution, the concave and convex matching of the contact surface between the abutment and the pressure rod can improve the pressing efficiency and avoid slippage as much as possible. The abutment is rotatably connected to the pressure roller, and the side of the abutment facing the pressure rod can always remain downward under the action of gravity, so that the abutment only produces a pressing force on the pressure rod, thereby reducing the jamming of the corners of the matching surface and making the rotation of the abutment smoother.

[0037] In summary, the present application includes at least one of the following beneficial technical effects:

[0038] 1. By covering the self-adhesive sealing layer of the waterproofing membrane with an alloy laminated film, the mechanical strength of the waterproofing membrane is improved, so that steel bars can be laid directly, simplifying the construction steps, shortening the working hours, and reducing the damage to the waterproofing membrane caused by construction materials. It can also serve as a bottom mold to facilitate subsequent construction, and improve the waterproofing performance of the membrane from multiple angles;

[0039] 2. The overlapping edge of the waterproofing membrane and the rest of the membrane share the alloy laminated film, and the overlapping edge and the rest of the layer structure are symmetrically distributed on both sides of the alloy laminated film. The self-adhesive sealing layer of the overlapping edge and the self-adhesive sealing layer of the adjacent membrane are bonded to each other, solving the problem of poor bonding compatibility between the self-adhesive sealing layer and the alloy laminated film. The self-adhesive sealing layer uses creep properties to minimize the gap and improves the anti-seepage ability of the overlapping edge.

[0040] 3. By setting a pressure roller to roll the waterproofing membrane, the membrane is made more dense and waterproof. A nail gun with the nail outlet facing downward is installed at the bottom of the machine body, and an abutment is set on the end face of the pressure roller. The abutment presses down the pressure rod of the nail gun during the rotation of the pressure roller, driving the gun body to fire needle nails at the waterproofing membrane to improve the connection strength between the waterproofing membrane and the roof panel. The pressure roller can be linked with the nail gun, so that the rolling of the membrane and the laying of the needle nails can be carried out simultaneously, which is conducive to shortening the construction period and speeding up the construction efficiency.

[0046] The following is combined with Figure 1-3 The technical solution of this application is described clearly and completely.

[0047] Example 1

[0048] Example 1 of the present application discloses a butyl rubber elastomer composite polymer self-adhesive waterproof roll material.

[0049] Reference Figure 1 A butyl rubber elastomer composite polymer self-adhesive waterproof roll material includes a self-adhesive sealing layer 1, and the upper surface of the self-adhesive sealing layer 1 is covered with a layer of alloy laminated film 2. The setting of the alloy laminated film 2 has many advantages:

[0050] 1. By utilizing the high mechanical strength of metal, the puncture resistance and tear resistance of waterproof membranes can be improved, and their ductility can be increased. This allows the setting of a protective layer to be eliminated during pre-laying construction, and steel bars can be laid directly on top of the waterproof membrane and concrete can be poured, thus shortening the construction period of roof waterproofing and reducing the damage to the waterproof membrane caused by construction.

[0051] Second, the surface of the metal material is smooth and hydrophobic, and placing the alloy laminated film 2 on the top layer of the waterproof coiled material can effectively improve the waterproof and water-isolating performance.

[0052] 3. The alloy laminated film 2 has a high density and high mechanical strength. Under the action of its own weight, it can make the surface of the roll material smoother and can also be used as a bottom mold for concrete, so that the thickness of the poured concrete is more uniform. In other embodiments, the number of layers of the alloy laminated film 2 can be increased to further improve the smoothness, bearing capacity, waterproof performance and mechanical strength of the waterproof roll surface.

[0053] Fourth, because concrete has poor ductility and is easy to crack, rainwater is likely to leak downward after the concrete above the waterproof membrane cracks. Casting and fixing the alloy laminated membrane 2 with reinforced concrete can also improve the ductility of the concrete layer, enhance the durability of the roofing method, minimize the rainwater that leaks to the surface of the waterproof membrane, and further improve the waterproof performance.

[0054] Reference Figure 1 The self-adhesive sealing layer 1 includes a polymer waterproof layer 11, a self-adhesive layer 12 and a release film 13 from top to bottom. A first burr 111 is provided on the side of the polymer waterproof layer 11 facing the alloy laminated film 2, and correspondingly, a second burr 21 is provided on the alloy laminated film 2. The first burr 111 and the second burr 21 are interlaced with each other, which can increase the contact area and improve the friction. The gap between the first burr 111 and the second burr 21 is filled with adhesive, and the physical mortise and tenon joint and the chemical glue-linking reaction work synergistically to further improve the bonding strength between the alloy laminated film 2 and the self-adhesive sealing layer 1.

[0055] The adhesive composition includes butyl rubber and tackifier. Butyl rubber has excellent sealing performance, but weak adhesion. Adding tackifier can improve the sealing performance while maintaining the viscosity. Similarly, the material of the self-adhesive layer 12 can also be selected as butyl rubber to reduce the difficulty of preparing raw materials.

[0056] In the rolled state, the release film 13 can isolate the self-adhesive layer 12, prevent the coil from rolling and bonding, and prevent the self-adhesive layer 12 from losing its stickiness when exposed to the air. The upper surface of the alloy laminated film 2 is covered with an anti-corrosion coating. Since the roof is in an outdoor environment and is easily corroded by rain and microorganisms, the anti-corrosion coating can protect the alloy laminated film 2.

[0057] When the construction temperature is low, the self-adhesive layer 12 can be heated to soften the butyl rubber and improve the creep property, so that the waterproof membrane can be more easily and firmly bonded to the roof panel.

[0058] Reference Figure 1, a single piece of waterproof coil has a full-length overlap edge 3 at the edge, and the overlap edge 3 shares the alloy laminate film 2 with the rest of the part. Within the overlap edge 3, the self-adhesive sealing layer 1 covers the alloy laminate film 2. Since the surface of the alloy laminate film 2 is smooth and hydrophobic, if the overlap edge 3 layer structure is not changed and the upper and lower layers are directly overlapped, the self-adhesive sealing layer 1 is bonded to the smooth alloy laminate film 2, and rainwater can easily penetrate along the edge of the coil. When the overlap edge 3 is changed to the above-mentioned layer structure, the self-adhesive layers 12 of adjacent waterproof coils face each other. The self-adhesive sealing layer 1 has a strong creep property, and the self-adhesive layer 12 of the overlap edge 3 is made of the same material as the self-adhesive layer 12 of the adjacent coil and is bonded to each other, which can minimize the gap between the two layers of waterproof coils and improve the waterproof ability at the overlap edge 3.

[0059] In addition, the reversal of the material sorting can also serve as a marker for the range of the overlapping edge 3, making it easier for workers to align the overlapping edge 3 during construction, making the joint between the two pieces of waterproof membrane more flat and beautiful, thereby improving the laying quality of the waterproof membrane.

[0060] Example 2

[0061] Example 2 of the present application discloses a construction device for a butyl rubber elastomer composite polymer self-adhesive waterproof membrane, which is used for the laying construction of the waterproof membrane in Example 1.

[0062] Reference Figure 2 , Figure 3 A construction device for a butyl rubber elastomer composite polymer self-adhesive waterproofing membrane comprises a body 4, a pressure roller 5 is rotatably connected to the bottom of the body 4, and an abutment member 51 is convexly provided on the end surface of the pressure roller 5. A nail gun 6 is installed on one side of the body 4, and the nail gun 6 comprises a gun body 61 and a pressure rod 62. The abutment member 51 intermittently presses the pressure rod 62 during the rotation of the pressure roller 5, thereby driving the gun body 61 to fire nails outward.

[0063] Reference Figure 3 , (combined with Figure 1 ) After the waterproofing coiled material in Example 1 is laid on the roof panel in an overlapping manner, the pressure roller 5 is used to roll the waterproofing coiled material, and the creep property of the self-adhesive layer 12 is used to compact the waterproofing coiled material, reduce the gap between the layers of the waterproofing coiled material and between the waterproofing coiled material and the roof panel, and further improve the waterproofing performance. The bottom of the pressure roller 5 is flush with the bottom of the gun body 61 of the nail gun 6, and both are in contact with the surface of the waterproofing coiled material. The pressure roller 5 and the nail gun 6 are linked, so that rolling the coiled material and laying the nails can be carried out synchronously, thereby saving man-hours and improving construction efficiency.

[0064] Reference Figure 2The bottom of the body 4 is provided with a rotating shaft 41, which is rotatably connected to the pressure roller 5 from the end surface center of both sides of the pressure roller 5. The top of the body 4 is provided with a gripping portion 42, which is welded from steel pipes. The round rod-shaped gripping portion 42 is more convenient for workers to hold. The pressure roller 5 is preferably a stone roller or a steel roller. Stone and steel have a large dead weight, and using a stone roller or a steel roller to roll the waterproofing membrane can achieve a better compaction effect.

[0065] Reference Figure 3 , (the outer shell of the gun body 61 is not shown) the gun body 61 of the nail gun 6 is fixed to the fuselage 4 by bolts. One end of the pressure rod 62 is hinged to the gun body 61, and the other end is a cantilever arm. The internal structure of the gun body 61 is the same as that of the stapler and will not be described in detail. The nail box 612 of the gun body 61 is filled with door-type nails, and a downward nail outlet 611 is provided at the bottom of the gun body 61. The pressure rod 62 of the nail gun 6 blocks the movement path of the abutment 51. During the downward movement of the abutment 51, the abutment 51 gradually presses and presses the pressure rod 62, and the downward nail outlet 611 shoots needle nails toward the waterproof membrane, thereby improving the connection strength between the waterproof membrane and the roof panel and preventing the membrane from warping and deforming. The abutment 51 is rotatably connected to the end face of the pressure roller 5 through the shaft 52. The contact surface between the abutment 51 and the pressure rod 62 is made into a concave and convex arc surface, which can improve the pressing efficiency and avoid slippage as much as possible. The abutment 51 is rotatably connected to the pressure roller 5. Under the action of gravity, the side of the abutment 51 facing the pressure rod 62 can always remain downward, so that the abutment 51 only produces a pressing force on the pressure rod 62, thereby reducing the jamming of the corners of the matching surface and making the rotation of the abutment 51 smoother.

[0066] The above are all preferred embodiments of the present application. Obviously, the embodiments described above are only preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made by ordinary technicians in this field based on the structure, shape, and principle of the present application without making any creative work should be covered within the protection scope of the present application.
