gather ethylene Polypropylene composite waterproof roll waterproof breathable membrane
- Product Introduction
Polyethylene polypropylene composite waterproof coiled material is a new type of waterproof coiled material, which is composed of the original polyethylene synthetic macromolecule material, the antiaging agent, the stabilizer, the adhesive aid, and the high degree new polypropylene polyester filament non-woven fabric, through an automatic production line. This product is developed on the basis of fully studying the existing waterproof and anti-seepage products according to the new requirements of modern waterproof engineering and waterproof and anti-seepage materials. This product is a new type of waterproof material, which is made of multi-layer polymer synthetic sheet materials and is compounded by new technology and new process.
- Product features
(1) Strong impermeability, high tensile strength, small linear expansion coefficient, easy bonding, large friction coefficient, good stability, harmless, and strong deformation adaptability.
(2) Good comprehensive technical performance with wide temperature range and long service life, chemical stability, corrosion resistance, mildew resistance and ozone resistance.
(3) The service life is more than 70 years under the condition of complete isolation from ultraviolet light.
- Scope of application
(1) It is suitable for roof waterproofing, groundwater waterproofing, indoor and outdoor walls of swimming pools and pools, and floor waterproofing and moisture-proof of various industrial and civil buildings.
(2) Water conservancy dam seepage prevention, tunnel waterproof seepage prevention, metallurgy and chemical pollution prevention planting roof waterproof, artificial lake, landfill and other waterproof and seepage prevention works.
- Construction method
Construction operation procedure
Acceptance and cleaning of base course (leveling course) → preparation of adhesive (preparation upon use) → treatment of additional layers in complex parts (internal and external corners, cornices, downcomers, pipe holes, etc.) → construction of waterproof layer → inspection of waterproof layer → after construction acceptance of protective layer.
1. The base course (leveling course) for laying waterproof coiled materials must be cleaned and watered to ensure that the base course is wet. (Note: The roof waterproof screed shall comply with GB50207-2002 Code for Acceptance of Roof Engineering Quality, and the underground waterproof screed shall comply with GB50208-2002 Code for Acceptance of Underground Waterproof Engineering Quality).
2. Use polyvinyl alcohol glue solution containing 5%~15% cement weight to prepare cement paste 4 adhesive, which must be stirred evenly without sedimentation, clot or segregation.
3. Before the construction of the main waterproof layer of the roof, the detailed nodes with centralized drainage and complex structure shall be sealed and the additional layer shall be pasted.
4. The sealing material is polyether polyurethane. If other sealing materials are selected, they should not contain mineral oil, vaseline and other chemicals that affect the performance of polyethylene.
5. Additional layers shall be paved at corners; Internal and external corners shall be made into R=20mm arc shape.
6. The waterproof coiled material shall be paved in full, and the adhesive shall be applied evenly on the base surface without exposing the bottom and piling up; After the adhesive is painted, the coiled material shall be paved randomly to prevent the bonding quality from being affected by too long a time.
7. The waterproof coiled material shall not be folded or stretched with force when paving, and the air and excess adhesive under the coiled material shall be removed while paving to ensure that the coiled material is tightly bonded to the base course surface and between each layer of coiled material.
8. The overlapping width of waterproof coiled material shall not be less than 100mm.
9. The joints of upper and lower layers and adjacent two sheets of coiled material shall be staggered by one third of the width.
