Elastomer（ SBS ）Modification asphalt Waterproof roll Yes benzene ethylene -Butadiene styrene (SBS) thermoplastic elastomer modified asphalt is used as impregnation and coating materials, polyester felt and glass fiber reinforced polyester felt are used as tire base, and the upper surface is covered with polyethylene film, fine sand, mineral flakes (particles), etc. as isolation materials. The prices of coiled sheet waterproof materials are not uniform according to different models.
Type and specification of SBS modified asphalt waterproof membrane:
1. According to physical properties, it can be divided into Type I and Type II.
2. According to the tire base, it can be divided into polyester tire (PY), glass fiber tire (G), and glass fiber reinforced polyester felt (PYG).
3. According to the upper surface isolation material, it can be divided into: polyethylene film (PE), fine sand (S), and mineral particles (M).
4. According to the following surface isolation materials, they can be divided into: fine sand (ps: mineral particles with fine sand particle size no more than 0.6mm) and polyethylene film (PE). Precautions for construction method:
1. Base treatment:
The base course must be solid and flat, free of looseness and peeling. If the surface flatness is poor or sanding occurs, chiseling treatment must be carried out. The roof can be constructed only when the water content is below 9%.
2. Cold bonding construction:
① Paving coiled materials: place coiled materials in a proper position, leave 10cm longitudinal and 20cm transverse joints at the overlapping edge, and the paving is required to be dense and flat, and the junction is fully coated The adhesive shall be dried for 20min and then rolled forcefully to make it compact and firm; ② Ending treatment: the end of coiled material at the ending shall be cut and pressed into the groove, It shall be pressed and fixed with metal batten nails, and the concave shall be sealed tightly with sealant.
3. Hot melt construction
① During construction, put the coiled materials in order, light the blowtorch or spray gun, and heat the coiled materials and the foundation layer with the blowtorch or spray gun. The distance between the base layer and the coiled materials should be 0.5m Evenly, roll forward evenly after melting the coiled material surface, compact and flatten it, seal the edges with a trowel before cooling the coiled material, and lap the surface High polymer SBS solvent waterproof coating shall be applied to the edges and special complex parts, and then applied again.
② Ending treatment is the same as cold bonding method
4. It is required to overlap 10cm longitudinally and 20cm transversely for coiled material paving
