polymer modified asphalt waterproof materials（Self-adhesive ）

A list,
Changhe brand self-adhesive rubber asphalt waterproof rolling material is made of SBS elastomer, viscosifier, various additives and so on. At normal temperature, it is made of strong waterproof polyethylene film or aluminum foil or non-woven cloth as the upper surface material or no film, and the peeling anti-stick isolation layer as the lower surface. The products comply with the industry standard gb23441-2009 "self-adhesive waterproof rolling material".
Second, the characteristics of
Self-adhesive: strong adhesive force, completely rely on their own adhesion to the grass-roots, leaving out the grass-roots coating brush adhesive or hot baking. It is economical, safe and environmental protection.
"Self-locking water" performance: the coil is completely strongly adhered to the base layer, which can limit the leakage caused by the damage of the coil to a local scope, and textile channeling water.
Excellent flexibility and extensibility: bending at -20℃ without fracture, suitable for base shrinkage and cracking deformation.
Self-healing: ability to heal punctured holes or fine cracks under stress.
Bond sealing: coil joints rely on their own bonding and sealing, joint bonding performance and coil with the same life.
Iii. Scope of application
The above table for polyethylene film self-adhesive film is widely used in all kinds of construction of non-exposed roof, underground and indoor engineering, but also for digging subway, tunnel, pool, canal and other engineering waterproof, especially for the project is not allowed to use open fire.
Non-membrane double-sided self-adhesive rolling material is only suitable for auxiliary waterproof, but also can be used for the bonding and sealing of the junction of two incompatible materials.
