APP Modified Bitumen WATERPROOF MATERIAL SBS

Elastomer (SBS) modified asphalt waterproofing materials in styrene - butadiene - styrene thermoplastic elastomer (SBS) modified asphalt impregnated and coated cover material, polyester felt, reinforced polyester felt as base, surface coated with polyethylene film, fine sand or mineral materials such as insulation material made of curly sheet waterproof material.
[standards] GB18242-2008 standard for elastomer modified asphalt waterproofing materials.
The classification and specification ]
According to the tire base is different, divided into polyester tire (PY) womb (G), glass fiber and glass fiber reinforced polyester mat (PYG);
According to the isolation material divided into polyethylene film on the surface (PE), fine sand (S), mineral aggregate (M).Under the surface of insulation material for fine (S), polyethylene (PE).
According to the physical and mechanical properties are divided into Ⅰ type and type II
Specification: coil nominal width is 1000 mm.
Elastomer modified asphalt waterproof coiled material specification sheet

Product system of the asphalt or thermoplastic elastomer (such as styrene - butadiene block copolymer SBS) and thermoplastic (such as random polypropylene APP or non-crystalline state a - polyolefin low molecular polymer APA) modified asphalt impregnated base, both sides are coated with elastomer or plastic body asphalt cover layer, on the surface with fine sand, ore material (sheet material), or cover made from polyethylene waterproofing materials.
The product has good waterproof properties and anti-aging properties, and has not flowing under the high temperature and low temperature embrittlement, construction simple, no pollution, long service life.
Interface is widely used in industrial and civil building, basement, toilet, sink and other waterproof and moistureproof, and Bridges, car parks, swimming pool, tunnels, reservoirs, such as the structure of the waterproof, moistureproof, steam trap, permeability and asphalt roofing maintenance works.SBS modified asphalt waterproof coiled material is especially suitable for cold, frequent area of building waterproof structure deformation, and APP modified asphalt waterproof coiled material is suitable for high temperature, strong solar radiation area of the building waterproof.
Construction key points:
(a) basic requirements:
Basic level must level off, clean, dry, the moisture content should be less than 9%, and uniform coating surface at the grass-roots level in base oil, with its dry rear can construction.
(2) coil the shop is stuck in order:
High order first, after low across;The same height first far then near;The same plane begins to spread from below.The shop is stuck direction for side slope < 3% when the direction of the parallel to the roof of the shop is stuck;Slope in the < between 3% and 15% when the direction of parallel or perpendicular to the roof of the shop is stuck;Slope > 15% when perpendicular to the direction of the roof of the shop is stuck.
(3) the shop is stuck method:
1, the melt method: using flame spray gun or other tools on the heating coil base and grassroots uniform heating, begin to melt and stay on the surface of asphalt in black light, baking while the shop is stuck coil, and roller compaction.At the same time should pay attention to adjust the flame size and speed, keep the asphalt temperature between 200-250 ℃.After the completion of construction, with cold adhesive should be to seal the overlapping edges.
2, cold sticking method: with rubber scraper to polymer modified asphalt adhesive or LengMa fat and cold glue evenly on the surface at the grass-roots level, and control the uniform thickness, coil the shop while with rubber roller pushed coil in order to eliminate air to compaction.When the environment temperature is lower than 15 ℃, melt method should be adopted dealing with overlapping parts and coil head position.
(4) lap processing:
Long side lap when single longitudinal and waterproof lap width of 100 mm, or double waterproof should be 80 mm or more;Short side lap single layer should be 150 mm or more, a double layer should be 100 mm or more. At the same time, paste evenly, not melt leakage or leakage, should have a small amount of extra hot asphalt or cold extruding and forming adhesive strip.
(5) check acceptance:
After the completion of the construction to make a thorough check to ensure that party without bubble, buckling, the water loss and large shell phenomenon, achieve smooth, beautiful, maintain waterproof coiled material life.
