At the same time, it also provides a broad space for the promotion and application of new waterproof membranes.

[0003] In addition to having good waterproof performance, waterproof membranes also require targeted features in certain different scenarios, such as decoration, heat insulation and thermal insulation. This type of membrane is widely used in places such as color steel roofs, tile roofs, glass surfaces and soft decoration packages.

[0004] Chinese patent application number CN201721803896.2 discloses a new type of self-adhesive waterproof membrane for color steel roofing. The membrane has a layered structure, and the layered structures are, from top to bottom, an upper covering layer, an upper asphalt self-adhesive layer, a carcass reinforcement layer, a lower asphalt self-adhesive layer, and a lower isolation protective layer. The layered structures are composited into one, with an overall thickness of 1.5-2.0 mm; the carcass reinforcement layer is a high-density polyethylene cross-laminated film with a tensile force of not less than 300 N / 50 mm and an elongation of not less than 300%. The high-density polyethylene cross-laminated film has excellent tensile strength, tear strength and high elongation, which can perfectly compensate for the low strength of ordinary coatings and the low elongation of ordinary membranes.

[0005] However, this new type of self-adhesive waterproof membrane for color steel roofing still has the following problems:

[0006] 1. The lack of decorativeness of the waterproof base surface makes it impossible to achieve a decorative effect, which reduces the applicability of the waterproof membrane.

[0007] 2. When overlapping, waterproof membranes are usually covered from top to bottom, which makes it easy for water to leak at the overlaps, and the waterproof effect is poor during long-term use. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Depend on Figures 1 to 6 Give, including:

[0033] The waterproof roll body 1 has a layered structure and includes a composite layer and an adhesive layer.

[0034] The composite layer includes polyester fiber rock wool 2, on which a metal color film 3 is thermoplastically formed. The metal color film 3 is thermoplastically mixed with aluminum ore metal powder, pigment and PVC particles;

[0035] The adhesive layer includes a butyl rubber 4 coated below the composite layer, and an isolation film 5 is provided below the butyl rubber 4. Through the arrangement of the polyester fiber rock wool 2, the metal color film 3 and the butyl rubber 4, the metal color film 3 can adjust the color of the outer surface of the waterproof membrane according to the pigment added to the metal color film 3 before thermoforming with the polyester fiber rock wool 2, so as to be laid in locations with decorative properties. At the same time, the combination of the polyester fiber rock wool 2 and the metal color film 3 also has excellent heat insulation and thermal insulation effects for locations such as mobile houses and color steel roofs.

[0036] Taking into account that the overlapping joints are prone to water leakage and seepage when the waterproof membrane is laid, a groove 6 is pressed on one side of the waterproof membrane body 1, and the extending direction of the groove 6 is consistent with the long side direction of the waterproof membrane body 1. A overlapping strip 7 is bonded to the other side of the waterproof membrane body 1. The material of the overlapping strip 7 is an elastic material. In this embodiment, the material of the overlapping strip 7 is rubber, and the bottom of the overlapping strip 7 is sprayed with butyl rubber 4. The overlapping strip 7 includes overlapping pieces 8 located on both sides of the top. The bottoms of the two overlapping pieces 8 are coated with butyl rubber 4, and one of the overlapping pieces 8 is bonded to the waterproof membrane body 1. A cavity 9 is opened inside the overlapping strip 7 along the length direction of the overlapping strip 7, and a plurality of hollow nails 10 distributed at equal intervals are provided at the bottom of the cavity 9. A plurality of soft bags 11 corresponding to the hollow nails 10 are provided on the top of the cavity 9. A foaming agent is provided inside the soft bag 11, and oxygen and a small amount of water are provided in the cavity 9. The oxygen and water are intended to react with the foaming agent to expand the foaming agent. A plurality of equally spaced impact grooves 12 are provided on the side of the overlapping strip 7 away from the main body 1 of the waterproof membrane. The impact grooves 12 are similar to the rectangular or circular gaps on a milk carton that are easy to buckle open. When the overlapping strip 7 is located on one side of the impact groove 12 and is impacted, the impact groove 12 is opened. Through the overlapping strip 7, the soft bag 11 and the impact groove 12, when the two waterproof membranes and the overlapping strip 7 are laid, the groove 6 of the main body 1 of the second waterproof membrane is located below the overlapping piece 8. The top of the overlapping strip 7 is pressed with an on-site tool to allow the hollow nail 10 to pierce the soft bag 11. The foam in the soft bag 11 flows out and reacts with oxygen and water to expand. After breaking through the impact groove 12, the groove 6 and the cavity 9 are completely filled, thereby enhancing the fit between the two waterproof membrane main bodies 1 and between the waterproof membrane main body 1 and the waterproof base surface, thereby enhancing the waterproofness of the overlapping joint of the waterproof membrane.

[0037] The ratio of aluminum ore metal powder, pigment and PVC particles in the metallic color film 3 is 0.3:0.5:0.92.

[0038] refer to Figure 6 and Figure 7 As shown, considering that after some hollow nails 10 pierce the soft bag 11, the hollow nails 10 are not separated from the soft bag 11, resulting in the foaming agent not flowing out, the hollow nail 10 includes a puncture portion at the top, and a vertical support portion is provided below the puncture portion. A plurality of circumferentially uniformly distributed through holes 13 are respectively provided on the puncture portion and the support portion. Through the provision of the through holes 13, even if the hollow nail 10 is not separated from the soft bag 11, the foaming agent inside the soft bag 11 can flow out directly from the through holes 13.

[0039] In order to ensure that the multiple waterproof membrane main bodies 1 still have excellent thermal insulation performance after being laid, the type of foaming agent is polyurethane foaming agent.

[0040] refer to Figure 7 As shown, the through hole 13 is opened obliquely upward. When the foam inside the through hole 13 expands, the oblique upward direction can be directly aligned with the impact groove 12, so that the impact groove 12 can be opened faster.

[0041] When using this utility model:

[0042] First, tear off the isolation film 5 at the bottom of the waterproof membrane body 1, lay the waterproof membrane body 1 on the waterproof base surface, then adhere one of the overlapping pieces 8 on the overlapping strip 7 to the side away from the groove 6, adhere the bottom of the overlapping strip 7 to the waterproof base surface, and adhere the overlapping piece 8 on the other side to the other waterproof membrane body 1;

[0043] Then, when laying the second waterproof membrane body 1, first push the overlapping piece 8 aside, then tear off the isolation film 5 of the second waterproof membrane body 1, so that the side edge of the second waterproof membrane body 1 is in close contact with the side edge of the overlapping strip 7, and then restore the overlapping piece 8 and bond it to the second waterproof membrane body 1;

[0044] Finally, use an on-site tool to press the top of the overlapping strip 7, allowing the hollow nail 10 to pierce the soft bag 11. The foam in the soft bag 11 flows out and reacts with oxygen and water to expand, breaking through the impact groove 12, so that the groove 6 and the cavity 9 are completely filled. This tool only needs to have a certain hardness, and it is best to be consistent with the width of the cavity 9, such as the edge of a mobile phone.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
