The metal polymer composite waterproofing membrane is made of metal foil and polymer materials as the main raw materials, and is produced by extrusion method. The metal composite film and the fabric are reinforced by a sub-composite process. It is a metal foil layer (aluminum foil or copper foil), which mainly acts against plant root puncture and has waterproof and impermeability.
The two sides or one side of the metal foil is a maleic anhydride graft modified polyethylene resin layer, which mainly functions as a waterproofing agent, and the layer also has a certain anti-plant root puncture effect. The lower layer of the product is a non-woven fabric layer, which is directly laminated on the resin ester waterproof layer, and can be bonded to the base layer of the cement structure by cement material, so that the product and the structural base layer are integrated to more effectively block the strong impact plant roots. Puncture. The upper layer of the product is based on the growth characteristics of different species and the actual conditions of the project, and the non-woven fabrics, felts, etc. of different thicknesses are mainly used to protect the waterproof and hindering materials, filter the sediment, prevent the loss of nutrient soil, discharge excess water and store certain The water is used for plant growth.
The product construction is added to the cement by special matching waterproof and root-resistant polymer adhesive. The prepared adhesive is bonded to the cement base layer, and the formed adhesive layer has the dual functions of waterproofing and blocking the plant. When the waterproof coil is accidentally When it is destroyed, the bonding layer can also play the role of waterproofing and blocking roots, which is not possessed by other materials, and more effectively guarantees the quality of the project.
