The product is impregnated with elastomer (SBS) or thermoplastic
(ASP, APAO, etc.) modified asphalt impregnated tire base, both
sides coated with elastic or plastically modified asphalt coating,
the upper surface is sprinkled with fine sand, mineral particles )
Or polyethylene film and the like.
The product is used with good water resistance and anti-aging
properties, and has a high temperature does not flow low
temperature is not brittle, the construction is simple, long
Widely used in industrial and civil buildings roofing, basement,
bathroom and bridges, parking, swimming pools, tunnels, reservoirs
and other buildings waterproofing, moisture-proof, steam,
impermeability and various types of roof maintenance works. SBS
modified bitumen waterproofing membrane is especially used for
waterproofing of buildings in cold and structural deformation
areas. ASPP modified bitumen membrane is suitable for waterproofing
of buildings in high temperature and strong solar radiation area.
Construction operation requirements
Basic requirements: grassroots must be smooth, clean, dry, moisture
content should be less than 9%, and then use the base oil evenly
painted brush base surface, to be dry before construction.
Coil paving order: the order of the first high, low after the
cross; the same height far and near; the same plane from the bottom
began to spread. Paving in the direction of the slope of <3%
parallel to the direction of the roof when the roof; when the slope
is between 3% ~ 15% parallel or perpendicular to the roof when
paving: slope> 15% perpendicular to the roof when paving.
Hot-melt method: Use a flame spray gun or other heating tools to
align the bottom surface of the coil and the base layer uniformly.
When the surface asphalt starts to dissolve and is in a black
state, the coil is bake and compacted with a roll. At the same time
should pay attention to adjust the size and speed of the flame, the
asphalt temperature maintained at between 200 ~ 250 ℃. After the
construction is completed, cold sealing adhesive should be used to
seal the tower.
Cold and sticky method: use rubber scraper to apply polymer
modified asphalt adhesive uniformly on the surface of grassroots,
and then spread the material while using rubber roller to promote
the web while removing air to compaction. When the environment is
stable below 15 ℃, hot melt method should be used to deal with the
tower site and the first part of the web.
Tower treatment: long side of the tower connected to the
single-layer waterproof tower width100mm, double waterproof80mm,
short-side tower connected to the single-layer should be150mm,
double should be100mm. At the same time, paste to be uniform, can
not leak or melt leakage coating, there should be excess hot melt
asphalt or cold adhesive extrusion and the formation of bar.
Inspection and acceptance: After the construction is completed to
conduct a thorough inspection to ensure that the water surface
without drum kits, wrinkles, off and a large shell and other
phenomena, so smooth, beautiful, thus ensuring the waterproof life
of the membrane.
1. The conditions of the basement are complex. It is very important
to finish the closing process. Therefore, it is necessary to
carefully construct and seal the overlap (or joint) to ensure the
integrity of the waterproof layer. The lap joint is the weak point
of the waterproof layer. Therefore Must be sealed edge processing.
2. The operator shall not wear nail shoes, should wear soft flat
3. Winter construction should choose the coil low temperature
flexibility lower than the temperature 10products, and the coil
stored at 0above the place before use into the scene, handling to
4. Hot-melt construction, brushing the grass-roots processing agent
must be dry for 4 hours (more sticky feet above) can be carried out
coil shop, in order to avoid fire, the construction site should be
equipped with the appropriate amount of fire-fighting equipment.
Package transportation and storage
1. Products using paper packaging or plastic tape roll packaging.
2. Transport to prevent the sun and rain, prohibit access to fire,
to prevent collision, protect the packaging intact.
3. The product should be sealed and stored in the warehouse, stored
in a cool and ventilated place, close to the fire.
4. Under normal storage and transportation conditions, the storage
period is 12
