Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof construction equipment, and particularly relates to a hot-melt device for overlapping SBS waterproof coiled materials. Background Art

[0002] SBS waterproofing membrane is a building waterproofing material made of polyester felt or glass fiber felt as the base, (styrene, butadiene, styrene thermoplastic elastomer) as the modifier, and covered with isolation materials on both sides. It is suitable for waterproofing of underground waterproofing projects, protective projects, tunnels, subways, roads, bridges and other buildings in industrial and civil buildings. The comprehensive performance of the membrane is excellent, especially the elongation and anti-aging performance are very good. According to the needs of the region and users, the product can maintain a good working condition in the range of -18 ℃— 105 ℃. The existing hot-melt construction method of SBS waterproofing membrane is generally to place the membrane in a predetermined position and heat the waterproofing membrane with liquefied gas. The use of liquefied gas device to melt the membrane has poor safety, is not energy-saving and environmentally friendly, and the device is large and not portable. Utility Model Content
