one function
SBS modified asphalt waterproof coiled material, which has good high temperature resistance, can be used in the temperature range of - 25 to 100 ℃, has high elasticity and fatigue resistance, as well as an elongation of up to 1500% and strong puncture resistance and tear resistance. It is suitable for waterproof engineering of industrial and civil buildings in cold regions and with large deformation and vibration.
Performance characteristics: good low-temperature flexibility, no cracks when reaching - 25 ℃; High heat resistance, no flowing at 90 ℃. It is characterized by good extensibility, long service life, simple construction and low pollution. The product is suitable for waterproofing works of Grade I and II buildings, especially for building waterproofing works in cold and low temperature areas and with frequent structural deformation.
Specification classification: according to physical indicators, it can be divided into two categories: I (- 20 ℃) and II (- 25 ℃);
According to the tire base, it can be divided into two categories: polyester tire and glass fiber tire; According to the covering materials, it can be divided into four categories: PE film (aluminized film), colored sand, shale flakes and fine sand; Width: 1000mm, with length of 10m and 15m; Thickness: polyester felt coiled material 3mm, 4mm, 5mm; Glass fiber felt coiled material 3mm, 4mm; Glass fiber reinforced polyester felt coiled material 5mm
Scope of application: It is widely used in waterproof projects such as roofs, basements and toilets of industrial and civil buildings, as well as waterproof and moisture-proof projects such as roof gardens, roads, bridges, tunnels, parking lots and swimming pools. For projects with large deformation, it is recommended to use polyester tire products with good extensibility, and other buildings should use relatively economical glass fiber tire products.
two Construction method
Construction method: before construction, the defects of the base course shall be cleaned, and the moisture content of the base course shall not be more than 9%. The construction shall be carried out after the special primer oil is painted and fully dried. The specific project construction and detailed structure shall be carried out in accordance with the waterproof design, acceptance standards and construction specifications of the project.
● The base course shall be dry, flat, clean, free of dust, sundries, oil stains and moss spots. If there are holes, holes and cracks, they shall be filled with cement mortar, and the protruding parts shall be chiseled flat.
● The base treatment agent shall be brushed against the wind.
● Apply adhesive on the surface of base course and coiled material, and reserve overlapping edges to apply joint adhesive.
● Pave coiled materials, exhaust and compact them.
● Paste the lap joint.
three matters needing attention
Storage and transportation:
1. Avoid sun and rain, and store in a dry and ventilated environment. The storage temperature shall not be lower than the compliance test temperature (- ℃) of products with corresponding specifications, and shall not be higher than 50 ℃. Vertical storage, no more than two layers high;
2. During transportation, it must be placed vertically, with a height of no more than two layers. It should be prevented from tilting or transverse pressure, and if necessary, it should be covered with tarpaulin.
3. Under normal storage and transportation conditions, the storage period is one year from the date of production.
