摘　　要：将天然钠基膨润土和高分子化学药剂加以混合,在工业用水的参与下充分搅拌均匀,在高温高压密闭的环境中充分反应,将反应后的物料通过真空挤出机制成致密薄片状产品,覆膜打卷最终制成新型膨润土防水毯。文章首先对新型膨润土防水毯的结构、原材料的选择和加工以及新型膨润土防水毯的生产工艺进行论述;其次通过测试新型膨润土渗透性能、模拟废水的对比试验和实际施工应用中的相互搭接表明,新型膨润土防水毯的应用领域拓展到海水、油类和渗透液复杂情况下的防水防渗,而且其性能要明显优于普通膨润土防水毯;最后,通过对新型膨润土防水毯在尾矿库防水防渗工程中可以替代现有防水卷材,并具有优良的防水防渗性能进行描述,体现了新型膨润土防水毯防水效率高、应用领域广、施工工程简便等优点。The natural sodium bentonite and organic polymer to be mixed, participation in industrial water. In the environment of high temperature and pressure sealed adequate response, the reacted material through a vacuum extruder into a dense sheet product, eventually produce a new film playing volume waterproof blanket. First, this article discuss new waterproof blanket structure, selection and processing of raw materials and new production processes bentonite waterproof blanket; Second, followed by testing new bentonite permeability, comparison of experimental and simulated wastewater actual construction applications overlap each other that new waterproof blanket applications extended to seawater, oil and permeate complex case of water seepage, and its performance is much better than ordinary waterproof blanket; Finally, through the new waterproof blanket waterproof in tailings seepage project can replace the existing waterproofing membrane, and has excellent water seepage described, reflecting the new waterproof blanket waterproof, high efficiency, wide application field, the advantages of simole construction work.
