SBS modified asphalt waterproofing membrane SBS is a ternary block polymer and a thermoplastic elastomer respected in the world. It is a strong and high elastomer at normal temperature and becomes a strong elastomer at high temperature. Close to the fluid state of linear polymers. SBS elastomer modified asphalt waterproofing membrane fills a gap in domestic building waterproofing. It has the incomparable advantages of ordinary paper-based asphalt felt: no flow at high temperatures, good low-temperature flexibility, fatigue resistance, anti-aging, strong toughness, good elasticity, excellent waterproof performance, easy construction operation, wide environmental adaptability, low cost, and heavy load It is light, requires little maintenance, is convenient, and has an effective waterproof life of more than 15 years, so it is favored by the majority of users. 1. It shows that the coil has excellent low temperature resistance and durability. It has an elongation of up to 150% and excellent elasticity at the working temperature. It can still maintain its flexibility from -5℃ to -25℃, and is more flexible in cold areas. Such products are used in many places for waterproofing projects. Polyester tires, composite fiberglass cloth, linen tires, etc. are used as the tire base. The upper surface is sprinkled with fine sand, mineral particles (flakes) or covered with polyethylene film, and the lower surface is sprinkled with fine sand or covered with polyethylene film to make it Adapt to the needs of various buildings and various climates. 2. Scope of application: It is used for waterproofing of general industrial and civil buildings, especially for waterproofing and moisture-proofing of roofs, basements, bridges, roof gardens, swimming pools, tunnels, parking lots, cold storage, etc. of high-end and high-rise buildings. It is more suitable for waterproofing in cold areas and buildings with easily deformed structures. 3.

Construction key points and precautions (1) Construction key points: Unroll the coil and align it with the film side down, then roll up one end and use a flamethrower Bake the underside of the roll. When baking until the film melts and the bottom of the roll becomes shiny and black with a thin molten layer, push and step on the roll with your feet to make the bottom layer stick. After positioning, roll up the other end and continue as above. At the interface and joint between rolls, the overlap width is 5 to 10cm. Use a flamethrower to melt and then press it tightly to firmly combine the top and bottom. (2) During construction, attention should be paid to that the base surface of the rolled material must be clean, dry, and smooth. When baking, the heating should be even. When the heated surface becomes fluid and produces a wave, it proves that the heating has been sufficient. Special care should be taken. The baking time should not be too long to avoid damaging the tire base. When heating and paving with foot pressure, it is appropriate to allow a small amount of mixture to overflow from the edge of the roll.
