Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waterproof coiled materials, in particular to a pre-laid waterproof coiled material. Background Art
[0002] A major problem that has troubled experts and users for decades in underground waterproofing projects is the quality of waterproofing of the base plate and side walls without construction space.
[0003] (1) Water leakage: When using traditional waterproof materials, there is no construction space on the bottom plate or side wall, so only external waterproofing and internal waterproofing can be used. The waterproof membrane is pasted to the base layer instead of the structural concrete itself. Once the waterproof membrane is damaged, groundwater will flow between the waterproof layer and the structural concrete and enter the building through the concrete cracks. At that time, even if a leak is found indoors, it is difficult to locate the actual location of the damaged waterproof material, making it difficult to carry out repair work.
[0004] (2) Influence of settlement: When traditional waterproof materials are bonded to the base layer, once foundation settlement occurs, the base layer is easily deformed and settled, and the waterproof layer is twisted and deformed accordingly, and easily detached from the base plate and side walls. The waterproof layer cannot be completely sealed, and the basement floor will be exposed to groundwater.
[0005] Therefore, how to provide direct full-adhesion waterproof protection for structural concrete in the base plate and side walls without construction space becomes a challenge. Summary of the invention
[0006] In order to make up for the above deficiencies, the utility model provides a pre-laid waterproofing membrane, aiming to improve the problems existing in the prior art.
[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pre-laid waterproof membrane, including a main body layer, a composite adhesive layer below the main body layer, a composite adhesive isolation layer below the adhesive layer, a composite adhesive layer above the main body layer, a composite nano layer above the composite adhesive layer, and a composite isolation layer above the nano layer.
[0008] Furthermore, the main body layer is made of a polymer sheet made of high-density polyethylene.
[0009] Furthermore, the nano-layer is uniformly attached to the colloid to form an organic protective layer, which can effectively protect the colloid.
[0010] Furthermore, the nano-layer is directly bonded using a double-sided tape.
[0011] Furthermore, the adhesive isolation layer, adhesive layer, main body layer, composite adhesive layer, nano layer and isolation layer are composited at one time to prevent the colloid and the main body material from being separated.
[0012] The utility model has the following beneficial effects:
[0013] One layer of waterproofing, two lines of defense, more reliable waterproofing effect.
[0014] One-time compounding to prevent separation of colloid and main material.
[0015] The back-coating adhesive layer process is adopted to enhance the adhesion of the overlapping edges.
[0016] The waterproof performance is not affected by the settlement of the main structure and effectively prevents groundwater infiltration.
[0017] The cement slurry during concrete pouring and the special high molecular polymer in the membrane bonding layer are bonded by wet curing reaction. The bonding strength increases with the increase of concrete compressive strength. When the concrete reaches the initial setting stage, the membrane bonding layer has completely reacted with the concrete surface layer to form a new waterproof layer.
[0018] The nano-coating produces an organic protective layer that effectively protects the colloid from UV damage that affects the peel strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 2 This is a partial enlarged view of a pre-laid waterproof membrane proposed by the utility model.

[0023] The following will be combined with the drawings in the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1-2The utility model provides an embodiment: a pre-laid waterproofing roll material, including a main body layer 3, a composite adhesive layer 2 below the main body layer 3, a composite adhesive isolation layer 1 below the adhesive layer 2, a composite adhesive layer 4 above the main body layer 3, a composite nano layer 5 above the composite adhesive layer 4, and a composite isolation layer 6 above the nano layer 5. The adhesive isolation layer 1, the adhesive layer 2, the main body layer 3, the composite adhesive layer 4, the nano layer 5, and the isolation layer 6 are compounded in one time to prevent the colloid and the main material from being separated. The main body layer 3 is a polymer sheet synthesized from high-density polyethylene. The nano layer 5 is directly bonded with a double-sided tape and uniformly adheres to the colloid to form an organic protective layer, which can effectively protect the colloid. The special flow channel design of the nano layer 5 system ensures that the nano coating is uniformly and tightly attached to the surface of the adhesive layer to form a whole. The nano layer 5 has the function of enhancing the peeling strength and can have a higher peeling strength with concrete.
[0025] The present invention adopts one-time molding and extrusion, which solves the tediousness and energy waste of secondary compounding, solves the adhesion problem between the polymer hot melt adhesive and the polymer substrate to the greatest extent, and at the same time improves the peeling strength between the self-adhesive waterproof membrane and the concrete, and adds a non-stick coating on the original self-adhesive layer, which solves the inconvenience caused by the pre-laying reverse-adhesive construction, and at the same time improves the adhesion between the self-adhesive and the concrete.
[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
