Modified asphalt waterproof coiled material for roads and bridges and preparation method of modified asphalt waterproof coiled material
The invention relates to the technical field of waterproof coiled materials, in particular to a modified asphalt waterproof coiled material for roads and bridges and a preparation method of the modified asphalt waterproof coiled material. The modified asphalt waterproof coiled material for roads and bridges comprises a sand layer, an upper surface modified asphalt layer, a tire base layer, a lower surface modified asphalt layer and an isolating layer; by weight, the upper surface modified asphalt layer is prepared from the following raw materials: 60 to 80 parts of asphalt, 10 to 20 parts of ethylene-butyl acrylate copolymer, 5 to 15 parts of ethylene-vinyl acetate copolymer, 5 to 15 parts of anhydride modified esterified rosin, 25 to 35 parts of a filler and 2 to 5 parts of silane coupling agent. According to the modified asphalt waterproof coiled material for roads and bridges, the low-temperature flexibility and shear strength can be improved, the heat resistance and water impermeability of the modified asphalt waterproof coiled material for roads and bridges can be improved, the requirement for construction conditions is low, and the impermeability after hot rolling is good.
本申请涉及防水卷材技术领域，具体涉及一种道桥用改性沥青防水卷材及其制备方法。所述道桥用改性沥青防水卷材，包括砂层、上表面改性沥青层、胎基层、下表面改性沥青层和隔离层，按重量份计，所述上表面改性沥青层的制备原料包括沥青60‑80份、乙烯‑丙烯酸丁酯共聚物10‑20份、乙烯‑醋酸乙烯共聚物5‑15份、酸酐改质酯化松香5‑15份、填料25‑35份、硅烷偶联剂2‑5份。本申请提供的道桥用改性沥青防水卷材可以提高低温柔性和剪切强度，还可以提高道桥用改性沥青防水卷材的耐热性和不透水性，且对施工条件要求较低，热碾后抗渗性好。
