AI Technical Summary
In traditional polymer self-adhesive composite waterproofing systems, the two waterproof layers cannot fit tightly together, causing the entire waterproofing system to fail at any position.
The design adopts multiple waterproof membranes, by setting overlapping parts between adjacent membranes, and using adhesive layers and anti-sticking layers to tightly fit the first waterproof layer and the second waterproof layer, and using the viscosity of the polymer adhesive to combine the two layers into a whole.
Even if the two waterproof layers fail at any position, the effectiveness of the overall waterproof system can still be maintained to ensure the waterproof effect.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to waterproof material technical field, especially related to a composite waterproof system. BACKGROUND
[0002] The main function of waterproof material is to prevent water from penetrating into the building interior, thereby preventing the structure from being damp, mildew and corrosion, in order to ensure the protection effect on the building, the failure of waterproof material should be avoided as far as possible. The traditional high polymer self-adhesive composite waterproof system is usually composed of two independent waterproof materials, the two waterproof layers cannot be closely attached, when the two waterproof layers are invalid at any position in the same waterproof surface, even if the invalid position is not at the same point, the whole waterproof system will be invalid. SUMMARY
[0003] In view of the above-mentioned related prior art, the composite waterproof system can combine two waterproof layers into one whole, ensure the waterproof effect, and has strong practicability.
[0004] In order to achieve the above purpose, the utility model adopts the following technology:
[0005] A composite waterproof system, comprising: a first waterproof layer, a second waterproof layer.
[0006] The second waterproof layer is arranged above the first waterproof layer and comprises a plurality of waterproof rolls arranged in sequence along the length direction of the first waterproof layer, and at least a part of the adjacent two waterproof rolls overlaps.
[0007] Further, the thickness of the sheet layer is not less than 0.8mm.
[0008] Further, the anti-adhesion layer is a polyethylene silicone oil film, and the thickness is 0.03-0.04mm.
[0009] Further, the anti-adhesion layer is fine sand, and the density is 0.5-0.7Kg / m2.
[0010] Further, the adhesive layer adopts a high molecular adhesive, and the thickness is 0.25-0.45mm, and the adhesive strength is not less than 0.8MPa.
[0011] Further, the surface of the other adhesive layer is provided with a second isolation film, and when applied, the other adhesive layer is in contact with the surface of the first waterproof layer.
[0012] The utility model has the advantages that the self-adhesion of the adhesive layer can adhere the first waterproof layer and the second waterproof layer together, so that the two waterproof layers are combined into one whole, even if the two waterproof layers fail at any position, as long as the failure is not at the same point, the whole waterproof system is still effective, so that the waterproof effect is ensured. BRIEF DESCRIPTION OF DRAWINGS
[0013] The drawings described herein are only for illustrating selected embodiments and are not all possible embodiments, and are not intended to limit the scope of the utility model.
[0014] Figure 1 It is a waterproofing membrane cross section schematic view of the embodiment of the application. DETAILED DESCRIPTION
[0015] To make the purpose, technical scheme and advantages of the utility model embodiment more clear, the embodiments of the utility model are explained in detail below with reference to the drawings, but the described embodiments of the utility model are part of the utility model and not all embodiments.
[0016] As Figure 1 Indicated, the present example provides a kind of composite waterproof system, including: first waterproof layer, second waterproof layer.
[0017] Second waterproof layer is arranged above first waterproof layer, including multiple waterproofing membranes arranged in turn along the length direction of first waterproof layer, and at least part of adjacent two waterproofing membranes overlap, to avoid the leakage of gap between adjacent two waterproofing membranes, and waterproofing membrane includes: sheet layer 1;Adhesive layer 2, has two layers, and is arranged on the upper and lower sides of sheet layer 1 respectively;Anti-adhesion layer 3, is arranged on one of adhesive layer 2, and first isolation film 4 is arranged on the length direction side of anti-adhesion layer 3 surface, in use, first isolation film 4 is torn off, and the adhesive layer 2 of adjacent waterproofing membrane is covered on the anti-adhesion layer 3 of waterproofing membrane that first isolation film 4 has been torn off.
[0018] Specifically, the thickness of sheet layer 1 is not less than 0.8mm, and sheet layer is made of thermoplastic resin material as main material, such as HDPE or TPO material made of high-density polyethylene resin or polypropylene resin and the like, to improve strength.
[0019] Specifically, anti-adhesion layer 3 is polyethylene silicone oil film, and the thickness is 0.03-0.04mm.
[0020] Specifically, anti-adhesion layer 3 is fine sand, and the density is 0.5-0.7Kg / m2.
