Production description

SBS modified waterproof asphalt roller sheet is a kind of new waterproof material developed in 1980s in Chinese chemical building material industry, It's made of SBS modified asphalt through scientific process with heat transferoil as carrier. Waterproof coiled material is mainly used for building wall roofing and the place such as tunnel road landfill, resist the outside rain Groundwater seepage of a flexible roll into flexible building materials products, as a foundation for engineering and no leakage connection between buildings, is the first barrier of the engineering of waterproof, plays an vital role in the whole project .The main products include asphalt waterproofing materials and high polymer waterproofing sheets.

Characteristic
1. The water resistance

2. The temperature stability

3. Mechanical strength, extensibility and resistance to fracture

4. Flexibility                                                                                                                                                             5. The atmospheric stability

Application and Introduction

Modified asphalt waterproofing materials Compared with the traditional oxidation asphalt modified asphalt, its temperature range expanded, coil made of smooth and soft, can be made into 3~5 mm thickness, can use single layer, has 15-20 years reliable waterproof effect.

Products are mainly divided into the following several kinds:

1, elastomer modified asphalt waterproofing materials (SBS coil).

2, plastomer modified asphalt waterproofing materials (APP coil).

3, self-adhesive polymer modified asphalt waterproofing materials (APF coil).

4, synthetic polymer waterproof coiled material (PVC EVA CPE ECB TPO)

5, SBC polyethylene polypropylene fiber waterproof coiled material (PP+PE+PP)

Construction requirements

Grass-roots grass-roots should have a certain strength, should not be a shell, loose, uneven, the seam roof and storehouse of the dust and foreign bodies must be removed. Basic requirement is dry, water content is less than 8%. Usually pale at the grass-roots level without obvious water mark or a 1 m * 1 m linoleum floor flat in a clean surface of the flat layer 3-4 h. Such as surface cover linoleum base color is still around and did not cover parts, no obvious watermarking, the moisture content has reached requirement. Method is to use a thermal spray gun baked molten coil bonding surface. Coil and grassroots can stick, also can stick or a stick, slope area in size, minimum adhesive, should be baked shale surface to asphalt melting and after covering the shale, then baked with coil. Should be with baking, with compaction. Lap side must have excess asphalt extrusion. Coil long side lap, filled with glue method is not less than 70 mm, the article point glue and glue not less than 100 mm; Short lap, full stick when not less than 100 mm, the empty shop, point glue and glue not less than 150 mm. Using double way up and down two floors coil should be staggered 1/3 or 1/2 width, different seam. Angle of Yin and Yang in roofing, gutter, rain water mouth, roof, overlapping and closed head node location, do not allow the existence buckling, empty drum, become warped edge, the phenomenon such as delaminating and slip. Also can use cold sticking method construction. Check construction quality construction after the completion of their own observation. Shall not wear cleats is engaged in the operation. Construction materials such as inflammables, should pay attention to fire safety, and should be equipped with fire fighting equipment. Coil should erect storage put ventilated place, avoid sun exposure, or contact with heat source.
