[0002] At present, waterproof membranes are mainly used in building walls, roofs, tunnels, roads, landfills, etc. They are a kind of flexible building material product that can be rolled into a roll to resist the leakage of external rainwater and groundwater. As a leakage-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] However, today's waterproof materials generally use one material or one material divided into two layers. The products are affected by the limitations of the single material itself, and their comprehensive performance indicators are difficult to meet the requirements. Even after adding additives, the improvement of their performance still has great limitations.
