Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coiled materials, in particular to a tear-resistant composite waterproof coiled material. Background Art

[0002] Waterproof membrane is mainly used for building walls, roofs, tunnels, roads, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist the seepage of external rainwater and groundwater. As a leak-free connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project.

[0003] When laying asphalt waterproofing membranes, the waterproofing membranes need to be cut accordingly to match the working surface according to the different shapes of the building's working surface. Due to the low tensile strength of asphalt, the asphalt layer of the asphalt waterproofing membrane is easily torn during cutting, affecting its use, so tear-resistant composite waterproofing membranes have emerged.

[0004] An existing patent (publication number: CN213006959U) discloses a waterproof coiled material. Aiming at the problem that the existing waterproof coiled material has weak sound absorption ability, poor waterproof effect, poor corrosion resistance at the bottom, which makes the coiled material susceptible to corrosion and reduces the service life, the following scheme is proposed, which includes a coiled material main body, a corrosion-resistant layer is fixedly connected to the bottom of the coiled material main body, a sound-absorbing layer is fixedly connected to the top of the coiled material main body, an anti-cracking layer is fixedly connected to the top of the sound-absorbing layer, a thermal insulation layer is fixedly connected to the top of the anti-cracking layer, and a waterproof layer is fixedly connected to the top of the thermal insulation layer. The beneficial effects of the utility model are: by arranging the corrosion-resistant layer, the sound-absorbing layer, the anti-cracking layer, the thermal insulation layer and the waterproof layer, the corrosion resistance of the coiled material main body can be improved, the sound absorption ability can be improved, and the service life of the coiled material main body can be improved. In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The waterproof roll is mostly exposed to the outside world. Due to the different temperature differences between day and night, the roll expands due to heat when exposed to sunlight during the day, and shrinks due to the lower temperature at night, which causes the waterproof roll to crack or even deform after long-term work, thereby affecting the waterproof performance of the roll; 2. The waterproof roll needs to be pulled during the laying process. The traditional waterproof roll has low tensile strength, which makes it easy to damage the internal structure of the roll during the laying and pulling period, thereby reducing the waterproof effect of the waterproof roll.
