产品介绍
高密度聚乙烯自粘胶膜防水卷材（简称 HDPE 自粘防水卷材），是专为地下工程开发的一种懵提供与后浇混凝土结构形成牢固结合效果的防水卷材。它是一种以高密度热塑性聚乙烯（HDPE）膜为防水基材，HDPE 膜的一个面上覆高分子自粘胶膜、合成粘合剂层外露面上涂抗环境变化保护层和隔离层构成，属于高分子自粘胶膜防水卷材。卷材长边一侧预留 70mm 宽合成胶粘剂搭接区。卷材自粘层和抗环境变化保护层具有自愈功能，与液态混凝土浆料反应固结后，形成防水层与混凝土结构的无间隙结合，避免层间窜水隐患，能有效提高防水系统的可靠性。
High-density polyethylene self-adhesive film waterproofing membrane (referred to as HDPE self-adhesive waterproofing membrane) is a waterproofing membrane specifically developed for underground engineering, providing a firm bonding effect with post-cast concrete structures. It is a type of high-molecular self-adhesive film waterproofing membrane, consisting of a high-density thermoplastic polyethylene (HDPE) film as the waterproofing substrate, with one side of the HDPE film covered with a high-molecular self-adhesive film, and the exposed surface of the synthetic adhesive layer coated with an environmental change-resistant protective layer and an isolation layer. A 70mm wide synthetic adhesive overlap area is reserved on one side of the long edge of the membrane. The self-adhesive layer and the environmental change-resistant protective layer of the membrane have a self-healing function. After reacting and consolidating with liquid concrete slurry, a waterproof layer forms a gapless bond with the concrete structure, avoiding the hidden danger of water leakage between layers and effectively improving the reliability of the waterproofing system.
