Product Definition "Puchuang" brand polyester tire backing EPDM waterproofing membrane is coated on polyester non-woven fabric with EPDM rubber coating in advance to make the coating penetrate.
It penetrates into polyester non-woven fabric, dries and compacts, and then uses EPDM rubber with excellent aging resistance as base material to add reinforcing agent, filler, antioxidant and purple resistance.
The exterior agent and accelerator are used to make the blend, and then the blend is formed into a new type of polyester tire backing by calender pasting, vulcanization, embossing, inspection and other processes.
Polymer waterproofing membrane product "Puchuang" brand polyester tire backing EPDM waterproofing membrane is bonded with cement base during construction because there are many fibers on the back of polyester tire.
It can also penetrate into the cement slurry like tree roots. When the rubber cement slurry binder solidifies, the coil and the cement layer will be firmly bonded together. There is no aging.
Mildew, hydrolysis, water channeling and other problems, easy and fast construction, especially suitable for underground waterproofing projects, can exceed 8% of the water content or as long as there is no water.
Full adherence is achieved on the uneven and bad base surface, which fundamentally solves the construction problem of water-proof system failure caused by water channeling.
1. Weather resistance, excellent aging performance, long service life, theoretically up to 50 years.
2. It has high tensile strength, high elongation, strong adaptability to base expansion or cracking, and little shrinkage deformation at the level.
3. Using matching rubber cement slurry binder, it can be constructed not only on wet foundation, but also on dry foundation, forming a complete waterproof body.
This system fundamentally solves the problem of building waterproofing system failure caused by water channeling.
4. Cement-based bonding can be used for cold construction on the base surface which exceeds 8% of water content or as long as there is no open water. It is easy to operate, wide adaptability and base surface.
It is a common precaution that it does not need smoothness and is convenient to achieve the target quantity of work better in basement and large-scale engineering construction, to speed up the construction progress and to avoid delaying the construction period.
The construction speed of water coil is one to two times.
Because of the use of "gasoline" as the dispersing medium of EPDM, bonded with rubber cement slurry, solvent-free, non-toxic and pollution-free, it is a green environmental protection product.
Scope of application
This waterproof roll material can adopt single-layer waterproofing method and cold construction. It is suitable for the roof waterproofing of various prefabricated, cast-in-situ industrial and civil buildings in the South and north of China as well as for the roof waterproofing of civil buildings. Underground works, bathrooms, toilets, damp proof and leakage proof, bridges, tunnels, dams and other building waterproofing works, especially for Class 1 and Class II buildings High-grade waterproofing works.
