Flexible pre-laid anti-sticking polymer waterproofing roll material

Abstract

This utility model relates to the field of waterproof membrane technology and discloses a flexible pre-laid reverse-adhesive polymer waterproof membrane, including a polymer substrate layer. The outer wall of the polymer substrate layer is coated with a weather-resistant coating, and a reinforcing layer is provided on the side of the polymer substrate layer away from the weather-resistant coating. This flexible pre-laid reverse-adhesive polymer waterproof membrane, with its reinforcing layer made of polyester nonwoven fabric, can improve tensile strength and tear resistance, enhance dimensional stability, inhibit shrinkage deformation, improve interlayer adhesion, and improve the overall integrity of the membrane. It is also resistant to chemical corrosion and aging, extending its service life. The honeycomb-like cross-section design of the reinforcing layer reduces material usage, making the membrane lighter and reducing the overall weight of the membrane, facilitating transportation and construction, and reducing the load pressure on the substrate. This enhances its flexibility and deformation adaptability, and provides excellent cushioning and impact resistance.
