Elastomer modified asphalt chemically resistant to root puncture waterproofing membranes Waterproofing membranes are mainly used for building walls, roofs, tunnels, highways, etc., to resist external rainwater, groundwater leakage, and a kind of roll that can be rolled into a roll. Flexible building materials, as a leak-free connection between the engineering foundation and the building, are the waterproof barriers of the entire project, and play a vital role in the entire project. The main products are bituminous waterproofing membranes and polymer waterproofing membranes. This article describes in detail the construction methods and precautions of waterproofing membranes.
The self-adhesive rubber asphalt waterproofing membrane is a self-adhesive waterproofing membrane with polymer resin, high-quality asphalt as the base material, polyethylene film and aluminum foil as the surface material, and a separation layer. The product has strong bonding properties and self-healing properties, and is suitable for construction in high and low temperature environments. It is divided into two types: self-adhesive with tire and self-adhesive without tire. It is composed of self-adhesive upper and lower self-adhesive rubber sandwiched between the tyre base, the upper covering surface is a vinyl film, and the lower covering surface is a peelable silicone oil film. Tireless self-adhesive is composed of self-adhesive glue, upper vinyl film and lower silicone oil film.

Elastomer-modified bitumen chemically resistant root puncture waterproofing membrane has poor cohesiveness of synthetic polymer waterproofing membranes and poor bonding reliability with adhesives. Therefore, adhesives are used when bonding with the base layer, and hot air welding is used at the joints. Ensure the reliability of the lap joints of the waterproof layer. At present, the synthetic polymer waterproofing membranes constructed by welding in China include PVC (polyvinyl chloride) waterproofing membranes, PE (polyethylene) waterproofing membranes, TPO waterproofing membranes, TPV waterproofing membranes, and synthetic polymer waterproofing membranes. Except for lap joints, other requirements for welding construction are exactly the same as those of cold-bonding synthetic polymer waterproofing membrane construction. Seam welding is the key to this process. Trial welding must be carried out before the membrane is welded. Welding construction of synthetic polymer waterproof coiled material. The hot-air welding method is generally suitable for the joint construction of thermoplastic synthetic polymer waterproofing membranes and the peeling test.
Product specifications: impermeable, 30min impermeable elongation at break ge, 10 (%) material asphalt. The first grade flexural strength of Linyi, Shandong Province meets the requirements. Compressive strength meets the requirements of tensile strength ge, 150 brand Shandong Yuexu. Tear strength ge, morphological layered shape rolled plate. Product introduction: The self-adhesive polymer waterproof membrane is made of rubber asphalt with active additives as the adhesive material, and the surface is covered with PE blue film, aluminized film, polyester film and release paper. It has strong extensibility and The self-healing function can heal small puncture damages and automatically fill small cracks in the base layer.
The coiled material and the adjacent coiled material are parallel overlapped. When the long and short sides are overlapped, the upper and lower coiled material overlap isolation film will be removed. Roll pressure exhaust. After the roll material is laid, use a soft rubber plate or roller to scrape from the middle to the other side of the roll material overlap direction and exhaust air to make the roll material fully adhere to the base surface. When laying the next coil, lift the release paper at the overlapping part of the lower coil, align the upper coil with the lap control line and stick it on the lower coil, scrape and exhaust the air to fully Full of sticky. Conservation and protection of finished products. Leave for 24 hours to 48 hours (the specific time depends on the ambient temperature, under normal circumstances, the higher the temperature, the shorter the time required). In high-temperature weather, the waterproof layer should prevent exposure to the sun, and can be covered with shade cloth or other items. Precautions. Since the construction of self-adhesive waterproofing membrane is relatively simple and convenient, but it should not be slacking when paving. It is necessary to pay attention to whether there is any air bubbles at all times, and the air must be discharged in time, so that the membrane will be smoother and its viscosity will be Stronger, conducive to later construction.
The temperature adaptation range is -15%~130℃. Good corrosion resistance, high spontaneous ignition point (265℃). High heat resistance, which is better than SBS modified bitumen waterproof membrane. APP modified bitumen waterproofing membrane is suitable for waterproofing and dampproofing of roofs, basements, toilets, etc. of industrial and civil buildings, as well as waterproofing of bridges, parking lots, swimming pools, reservoirs, tunnels and other buildings, especially suitable for high temperature or strong sun Waterproofing of buildings in radiation areas.
Prepare materials, tools and facilities. Operation process. Process flow. base level leveling and cleaning, elastic thread, coil pre-laying, self-tapping nails fixed coil seam lap welding, special part treatment, fixing, closing and pressing, sealing material edge sealing, and acceptance. Cleaning up the base layer: Before the waterproof roof construction, clean the dust and sundries on the surface of the accepted base layer. Paving roofing PVC waterproof membrane. Align the rolled material that has been stripped of the release paper with the baseline that has been bounced lightly, and then compact it. After the start-end paving is completed, one person slowly lifts the peeling barrier paper and rolls it into the paper core tube and moves forward. Two people holding the roll material simultaneously roll the roll material forward along the reference line. Note that the moving speed of the two persons lifting the coil should be the same and coordinated. It should not be too slack when rolling. After laying a roll of material, use a long-handled rolling brush to completely remove the air under the roll from the beginning, and then use a large pressure roller or a hand-held portable vibrator to press the roll. Really, stick firmly.
