Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof coiled materials, and specifically relates to a composite modified asphalt waterproof coiled material. Background Art

[0002] Asphalt waterproofing membrane refers to a rolled material made of asphalt material, tire material and anti-stick material spread on the surface, also known as felt. It has poor temperature stability. During use, the felt is generally laid directly on the ground where it needs to be laid. Under the action of gravity, the felt is driven to stick to the ground to achieve a waterproof effect.

[0003] When laying asphalt membranes, the asphalt is generally baked to ensure the connection between different membranes. Once the asphalt on the outermost side melts, it is easy to cause the internal filler to shrink. As a result, even if the two membranes are fused together, the internal filler is still separated. As a result, after the asphalt is cooled and cracks appear, the internal filler does not contact each other and a fault occurs, which reduces the waterproof effect of the waterproof membrane. Therefore, a composite modified asphalt waterproof membrane is needed to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a composite modified asphalt waterproofing membrane to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a composite modified asphalt waterproofing roll material, comprising a roll material body and a reinforcement layer, the roll material body comprising a polyester tire base layer, a first SBS modified asphalt impregnated material layer and a second SBS modified asphalt impregnated material layer, the polyester tire base layer is connected between the first SBS modified asphalt impregnated material layer and the second SBS modified asphalt impregnated material layer, the reinforcement layer comprises a plurality of first fiber filaments, a plurality of second fiber filaments and a plurality of third fiber filaments, the plurality of first fiber filaments and the plurality of second fiber filaments are divided into three layers and cross-connected with each other, the plurality of third fiber filaments are respectively connected to the intersection points of the plurality of first fiber filaments and the plurality of second fiber filaments of the three layers, and the plurality of first fiber filaments and the plurality of second fiber filaments of the three layers are respectively connected in the polyester tire base layer, the first SBS modified asphalt impregnated material layer and the second SBS modified asphalt impregnated material layer.

[0006] By setting the above structure, since the plurality of first fiber filaments, the second fiber filaments and the third fiber filaments are respectively connected to the polyester tire base layer, the first SBS modified asphalt impregnated material layer and the second SBS modified asphalt impregnated material layer, the plurality of first fiber filaments, the second fiber filaments and the third fiber filaments cooperate with each other to strengthen the strength of the coil body, and enhance the connection stability between the polyester tire base layer, the first SBS modified asphalt impregnated material layer and the second SBS modified asphalt impregnated material layer, so that when the asphalt of the coil melts, other parts of the coil body are not prone to partition or cracks, thereby ensuring the normal waterproof effect of the coil.

[0007] As a preferred embodiment, the first SBS modified asphalt impregnated material layer is connected to the second isolation membrane.

[0008] As a preferred implementation, the second SBS modified asphalt impregnated material layer is connected to the first isolation membrane.

[0009] As a preferred implementation, the reinforcement layer and the coil body are arranged between the first isolation film and the second isolation film.

[0010] As a preferred embodiment, the first fiber filaments, the second fiber filaments and the third fiber filaments are all arranged vertically.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model is provided with a coil body, a first fiber filament, a second fiber filament and a third fiber filament. Since a plurality of first fiber filaments, a second fiber filament and a third fiber filament are respectively connected to a polyester tire base layer, a first SBS modified asphalt impregnated material layer and a second SBS modified asphalt impregnated material layer, a plurality of first fiber filaments, a second fiber filament and a third fiber filament cooperate with each other to strengthen the strength of the coil body, and enhance the connection stability between the polyester tire base layer, the first SBS modified asphalt impregnated material layer and the second SBS modified asphalt impregnated material layer, so that when the asphalt of the coil melts, other parts in the coil body are not likely to be cut off or cracked, thereby ensuring the normal waterproof effect of the coil;

[0013] The utility model provides a first isolation film and a second isolation film, which cooperate with each other to isolate the two sides of the coil body from the outside world, so that the coil body is not easy to stick to each other during the winding process.
