EPDM-TBD reactive rubber self-adhesive waterproofing membrane

1. Product Introduction

EPDM-TBD reactive rubber self-adhesive waterproofing membrane (hereinafter referred to as EPDM-TBD self-adhesive membrane) is a high-strength and weldable new type of EPDM self-adhesive waterproofing membrane that our company adopts independent cutting-edge technology and new process equipment. Before the EPDM membrane is extruded, the (SD-JH) technology is used to directly polymerize with the ethylene propylene rubber surface and isobutene tackifying material and extrudes with isolation film. 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.

2. product characteristics

★Super long-lasting bonding force, the coil self-adhesive layer is directly polymerized, which cannot be peeled off, sealed and waterproof without water channeling.

★Domestic and foreign polymer self-adhesive waterproofing membrane: the first material surface directly form a self-adhesive layer bonding technology, can be combined with concrete reaction bonding length, to achieve permanent waterproof effect

★Super resistant to weather aging, ozone resistance, UV resistance, can meet the requirements of various environmental conditions.

★High strength, high elongation, strong puncture resistance, high bending, excellent flexibility, can adapt to the deformation of various building structures.

★Wet construction, lap can be welded, change the traditional EPDM can not be welded.

★Excellent high and low temperature resistance, up to -40℃No cracking, asphalt and other coils can not be achieved.

★It has excellent chemical resistance and can resist the erosion of chemicals in various natural environments for a long time.

★The material carrier is light, non-toxic, tasteless, green and environmentally friendly, blocking the root system, and can make the residence ecological.

★Cold construction, no need to use open fire operation, construction operation is simple, safe and environmentally friendly, convenient and fast.

5. adaptation range

1. It is suitable for waterproof projects such as industrial plants, commercial houses, civil underground buildings, subways, tunnels, bridge decks, grain depots, etc.

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 process

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

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 process:

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

2. Dry paving 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 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 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.
