【product description】
Polymer self-adhesive film (non-asphalt-based) waterproofing membrane is a multi-layer composite waterproof material with superior performance, including a layer of high-density polyethylene (hdpe) polymer film, polymer adhesive layer and unique process reaction. Inorganic polymer particles.
The high-density polyethylene film used in the product is made of high-quality high-density polyethylene resin, which combines anti-aging agent, antioxidant, ultraviolet absorber, stabilizer and other functional materials. It adopts the international advanced injection molding technology. Excellent performance; the polymer binder used is a macromolecular binder, which is good at high and low temperature; the inorganic polymer particles used are pre-treated quartz materials and have strong adhesion to pre-lay concrete.
The polymer self-adhesive film (non-asphalt-based) waterproofing membrane can be chemically cross-linked and physically entangled with the poured concrete to achieve high-strength and permanent bonding, which can completely prevent “water-repellent” and is not affected by the base layer displacement. The effect is also to maintain high peel strength in long-term immersion environments. Convenient construction, simple processing can be added to the cast skeleton reinforcement.
【Features】
◆ Form a permanent organic bond with concrete to prevent moisture from penetrating into the gap between the waterproof membrane and the structure.
◆ No protective layer is required, and it can be walked on the waterproof membrane immediately after construction.
◆One-sided bonding, integrated with structural concrete, independent of the displacement of the base layer.
◆The construction period is short, which is one-third shorter than the ordinary coil.
◆Convenient construction, simple processing can be added to cast skeleton reinforcement.
◆ It can maintain high peel strength in long-term immersion environment.
◆Long service life and good weather resistance.
◆ Excellent puncture resistance.
[Scope of application]
The polymer self-adhesive film waterproofing membrane is specially designed for underground waterproofing difficulties, so it is only suitable for underground or tunnel waterproofing engineering, and is not recommended for building vertical wall or roof waterproofing.
