The invention discloses a composite flame-retardant root-resistant waterproof roll, and belongs to the field of building waterproof materials. The structure is composed of a flame-retardant polyolefin polymer layer, a resin fusion layer, a metal plasma static barrier layer and an adhesive layer in sequence from top to bottom. The metal composite barrier layer is made of aluminum foil and a composite material, so that a small-molecular-weight plasticizer can be effectively prevented from being migrated to the polyolefin high-molecular sheet. The stable performance of the high-molecular sheet is ensured, the long-term working life is ensured according to the material design, a grafting chemical reaction of polyethylene glycol terephthalate grafted maleic anhydride is adopted, a functional group with reactivity is introduced into a side group of resin, the compatibility of a polyolefin polymer and a metal aluminum foil is improved, and a physical root blocking principle is adopted, so that the mechanical property of the high-molecular sheet is improved. The root system is prevented from puncturing the coiled material through the mechanical strength and hardness of the material, a root blocking agent does not need to be added, and the root blocking effect is more stable and reliable.
本发明公开了一种复合型阻燃阻根防水卷材，属于建筑防水材料领域。其结构从上而下依次由阻燃聚烯烃高分子层、树脂融合层、金属等离子静电阻隔层和胶粘层组成。本发明采用金属复合阻隔层采用铝箔及复合材料，可以有效的防止小分子量增塑剂迁移至聚烯烃高分子片材。确保高分子片材性能稳定，按照材料设计保证长期工作年限，采用聚对苯二甲酸乙二醇酯接枝马来酸酐接枝化学反应，将具有反应性的官能团引入树脂的侧基，提高与聚烯烃聚合物与金属铝箔的相容能力，采用物理阻根原理，通过材料本身的机械强度和硬度来阻止根系刺穿卷材，无需添加阻根剂，阻根效果更稳定可靠。
