EPDM-TBD reactive rubber self-adhesive waterproofing membrane

(a direct activationThe integrated reaction self-adhesive waterproofing membrane formed on the surface of EPDM cannot be peeled off)

1.EPDM-TBD product description:

EPDM-TBD reactive rubber self-adhesive waterproofing membrane (hereinafter referred to as EPDM-TBD self-adhesive membrane) is a high-strength, weldable EPDM self-adhesive waterproofing membrane that our company adopts independent cutting-edge technology and new process equipment. In the process of producing weldable EPDM waterproofing membrane, the (SD-JH) technology is used to directly activate the polymerization reaction between the surface of EPDM and isobutyl tackifying material and extrude with isolation film before the extrusion of EPDM membrane. Since the self-adhesive layer is generated by the material itself and cannot be peeled off, there is no separation and peeling phenomenon caused by the combination of the traditional self-adhesive coil main material and the base material of different materials of thermal adhesive. EPDM-TBD self-adhesive waterproofing membrane extrusion is the first at home and abroad, self-adhesive layer with high strength of the pressure sensitive and reactive, can form a sucker effect with the cast-in-place concrete base and form a chemical bond with the reaction of inorganic substances in concrete, and concrete "skin type" full sticky effect. The coil can also be welded, the bonding strength of the coil and the coil self-adhesive layer is high, the material is environmentally friendly, non-toxic, tasteless, flexible, durable and physical properties are better than the traditional asphalt self-adhesive coil, which can meet the design requirements of modern high-grade buildings for one hundred years. It is the best waterproof material for various building waterproof projects and the preferred waterproof material for green buildings at home and abroad.

4. The way the product is pasted in the application

(1) Long edge: use single-sided adhesive reverse edge self-adhesive layer and single-sided adhesive, remove the isolation film directly paste lap.

（2) Short side: double-sided adhesive bottom layer is used for pasting, double-sided adhesive and single-sided adhesive isolation film are removed from the butt joint of the two short sides for direct butt joint bonding, and finally sealant is applied to the joint on the surface.

（3) Special parts: according to the construction specification of waterproof coiled material, single-sided adhesive and double-sided adhesive are combined with each other for pasting.

5. Scope of adaptation

(1) It is suitable for industrial plants, commercial residential buildings, civil underground buildings, subways, tunnels, bridge decks, grain depots and other waterproof projects.

(2) It is also suitable for waterproof projects such as wooden structure, metal structure and schools, airports, hospitals and exhibition halls with high environmental safety requirements.

6. Construction method

According to the project and construction site, the EPDM-TBD self-adhesive coil can be pre-laid anti-adhesive method, self-adhesive dry paving method and wet paving method.

(1) Pre-laying and anti-sticking method:Concrete base plate suitable for underground works. During construction, the coil is laid empty (or partially bonded and fixed) on the base layer, with the self-adhesive layer facing upward.

Construction method process:

Base layer cleaning → joint part strengthening treatment → pre-laying self-adhesive coil → overlapping coil → joint sealing (welding) → removing the separation film on the coil surface and spreading cement powder → protective layer.

(2) Self-bonding dry laying method:Suitable for foundations, basement roof panels or exposed roof panels. The base surface of the concrete structure is coated with the base treatment agent (both aqueous and oily). After the base treatment agent is dried, the self-adhesive coil can be paved.

Construction method process:

Base cleaning → base surface treatment agent painting → detail node treatment → large surface paving, roll bonding-lap roll bonding → local lap welding → protective layer (Note: protective layer is not required for exposed roof)

(3) Wet laying method:It is suitable for the foundation, basement roof or exposed roof panel in poor conditions, and can be constructed by wet paving method, which can be used to scrape the cement mortar on the base surface and then spread the waterproof coiled material.

Construction method process:

Base course cleaning → configuration of cement slurry → detailed node treatment → pre-laying of coiled material → scraping of cement slurry → laying of coiled material while tearing the film → large surface exhaust, roll pressure bonding → lap bonding compaction → lap edge sealing and welding treatment → protective layer.

2.EPDM-TBD self-adhesive coil and traditional asphalt self-adhesive coil advantages

Humans to survive, to live a long life, air quality is the most critical. Now the living environment is good or bad, can be said to involve every industry, our waterproof industry is related to the life of each of us. Because, our living and contact (such as residential areas, shopping, subway tunnels, airports, etc.) buildings are inseparable from the waterproof products. Therefore, the selection of waterproof materials is particularly important. The following from several aspects of the EPDM-TBD reaction type self-adhesive waterproofing membrane and traditional asphalt waterproofing membrane difference.

1、 Compare it from an environmental point of view.

(1)SBS waterproofing membrane:The main materials are asphalt and softening oil. From the perspective of raw materials, such products themselves contain benzene and hydrocarbons. During the production and heating process, a large amount of harmful gases are released, causing environmental pollution and also causing erosion to the human respiratory tract and skin.

(2)EPDM-TBD self-adhesive coil:The main material is ethylene propylene rubber elastomer, the material itself is non-toxic and tasteless, the company adopts new technology to produce without any vulcanizing agent, accelerator and solvent, so in the production of heating process does not produce any toxic substances, the gas on the air environment can not cause any pollution, at the same time on the human respiratory tract and skin can not cause any erosion.

(3) in the practical application of coilSince the substances contained in SBS asphalt coils are unchanged, no matter where the coils are used in the project, the toxic substances contained in the later materials will continue to volatilize outward, pollute the air, damage the person and cannot be eliminated. And EPDM-TBD self-adhesive coil, the material does not contain solvent, forming construction will not have the problem of gas emission, can not create any air pollution.

2、 Compare product performance

3、 Compare the labor intensity of workers in construction.

(1) from the weight, SBS waterproofing membrane 10m²It weighs about 35kg, while the EPDM-TBD waterproofing membrane is 20 m.²Weighing about 30kg, the same area difference of 1 times the weight, the labor force of workers can be reduced by more than half.

(2) from the construction speed, because the EPDM-TBD self-adhesive coil is relatively soft, in the construction process is not easy to bulge, do not need too much extrusion, and SBS self-adhesive coil is hard, easy to bulge in the construction process, not only need to squeeze, but also take more time, paving speed is not EPDM-TBD so fast.

4、 Compare from special wooden or steel roof works

(1) SBS asphalt self-adhesive waterproofing membrane cannot be made on the wooden structure roof, because the solvent in the membrane corrodes the wood, which will cause the wood to rot and cause engineering danger, while EPDM does not contain any solvent and will not cause corrosion to the wood material. It can be directly bonded by removing the isolation glue.

(2) on the steel structure roof, SBS asphalt self-adhesive coil will crack and fall off after a period of time, while the EPDM-TBD self-adhesive coil -40 ℃ will not crack and will not fall off after long-term use.

In summary, it can be seen that EPDM-TBD reactive self-adhesive waterproofing membrane is an environmentally friendly and ecological product. It is a high-quality product with high performance and good quality. It is a product with simple construction, convenient operation, fast and efficient operation. It is a product that can be applied to a wide range of waterproof applications in buildings made of various materials. Environmental protection waterproof, please pay attention to the EPDM-TBD reaction type self-adhesive waterproofing membrane.
