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 the latest process equipment to directly activate the polymerization reaction between the surface of EPDM and isobutyl tackifying material and extrude with isolation film before the EPDM membrane is extruded by using (SD-JH) technology in the process of producing EPDM waterproofing membrane. Since the self-adhesive layer is generated by the material itself and cannot be peeled off, there is no phenomenon that the main material of the traditional self-adhesive coil and the thermal adhesive are easily separated and peeled off due to the coating of different materials. The one-time extrusion process of EPDM-TBD self-adhesive waterproofing membrane is the first at home and abroad. The self-adhesive layer has super pressure sensitivity and reactivity, can form suction cup effect with cast-in-situ concrete base layer and react with inorganic substances in concrete to form chemical bond combination, thus realizing "skin-type" full adhesion effect with concrete and the membrane can be welded. The bonding strength of the self-adhesive layer between the membrane and the membrane is high, and the material is environmentally friendly, non-toxic, tasteless, flexible, durability and physical indicators are better than the traditional asphalt self-adhesive membrane, can meet the demands of modern ecological housing and the design requirements of a hundred years of life, is the best waterproof material for various building waterproof projects, but also the first choice of green buildings at home and abroad.

(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

Human beings to survive, to live a long life, air quality is the most critical, the living environment is good or bad related to each industry, especially the waterproof industry is related to the life of each of us. Every day we live and work in contact with all the buildings (such as residential quarters, shopping, subway tunnels, airports, etc.) are inseparable from waterproof products, therefore, the selection of green 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、 Comparison of environmental protection angle

(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, which release a large amount of harmful gases during the production and heating process, 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 process production process does not contain any vulcanizing agent, accelerator and solvent. In the production of heating process does not produce any toxic substances, the air environment will not cause any pollution, human health will not cause any erosion.

(3) Secondly, in the practical application of coilBecause 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 materials will continue to volatilize outward, pollute the air, damage the body and cannot be eliminated. And EPDM-TBD self-adhesive coil, the material does not contain solvent, there is no problem of harmful gas volatilization after molding construction, and there is no pollution to the air.

3、 Comparison of labor intensity of workers in construction

(1)Product weight comparison: 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）Comparison of construction speedBecause the EPDM-TBD self-adhesive coiled material is relatively soft, it is not easy to bulge in the construction process and does not need too much extrusion, while the SBS self-adhesive coiled material is hard, and bulging is easy to occur in the construction process, which not only needs extrusion, but also takes more time, and the paving speed is naturally not as fast as EPDM-TBD.

4、 Comparison of special wooden or steel roof works

(1) wooden structure roof can not do SBS asphalt self-adhesive waterproofing membrane, because the membrane contains solvent will corrode the wood, so that the wood rot shorten the service life of the wood and cause engineering danger. EPDM does not contain any solvent, will not cause corrosion to wood materials, remove the isolation film can be directly bonded, the use of extremely convenient.

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

In summary, the EPDM-TBD reactive self-adhesive waterproofing membrane is an environmentally friendly 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; It is a waterproof product that can be applied to a variety of materials and buildings.
