Description

Technical Field

[0002] Cross membrane is an important component of waterproofing membrane. Waterproofing membrane is widely used in building walls, roofs, tunnels, roads, landfills and other fields that require waterproofing. It mainly plays the role of blocking external rainwater or preventing underground water seepage. The cross membrane is different from ordinary single-layer membrane or multi-layer membrane due to its cross-laminated structure. It has thermal stability, dimensional stability, bidirectional tear resistance, and bidirectional consistent tension. During the use of waterproofing membrane, the cross membrane mainly plays a role in waterproofing and strength. Therefore, the cross membrane not only requires a high tensile strength, but also a high nail rod tear strength.

[0003] However, the current cross membrane is usually pasted with adhesives, and then pressed to combine and install various materials and the cross membrane. Therefore, during long-term use, the material and the cross membrane may be separated, and the stability is poor. To solve the above problems, we propose a multi-layer composite high-strength cross membrane. Utility Model Content
