product description

 

The SPL (styrene-butadiene rubber) is used as the main modifier to modify and thicken the petroleum asphalt, and then with other polymer hydrophilic auxiliary additives to make the coil rubber, and then the high-quality filament The polyester felt is a pre-laid polyester tire self-adhesive waterproofing membrane made of a tire base, and the waterproof layer can be sealed with the structure, thereby solving the problem of leakage of hydrophobic water.

product description

 

The high-quality long-fiber polyester felt is used as the base material, and the petroleum asphalt is modified with SBS thermoplastic elastomer rubber (styrene-butadiene-styrene) as a modifier to prepare a rubber layer dip coating material. Fine sand, mineral pellets or polyethylene film is an elastomer modified asphalt waterproofing membrane made of cladding material.

Construction process

 

Grassroots requirements

 

The base layer is dry and solid, free of sediment, garbage, no empty drums, loose, sanding.

 

Coating treatment agent

 

Spray or roll the matching base treatment agent to the base layer to ensure that the base treatment agent is uniform and full of the base layer.

 

Trial roll

 

The coil material is spread out on the base surface, and the elastic wire or the overlapping edge of the adjacent coil material is aligned to ensure the overlapping width, and the stress is released after being released.

 

Hot melt paving

 

The flame is baked on the lower surface and the base surface of the coil, and the gel melts and rolls the coil in time, and is compacted and exhausted, so that the coil and the base surface are closely adhered.

 

Lap processing

 

At the same time of hot-melt laying, press the lap joint with a pressure roller to extrude 5~8mm molten asphalt (considered as reliable lap joint).
