AI Technical Summary
Traditional waterproof membranes are easily damaged when punctured by sharp objects, leading to waterproofing failure, affecting building quality and increasing maintenance costs. Furthermore, their puncture resistance is insufficient in special environments.
The membrane adopts a composite structure of a protective wear-resistant layer and a waterproof layer. The protective wear-resistant layer includes a silane-modified polymer coating and a polyester fiber fabric layer. The waterproof layer is made of polyvinyl chloride and high-density polyethylene. A heat-insulating membrane layer with honeycomb holes is set in the middle layer. Combined with modified bitumen adhesive and silicone paper adhesive layer, the wear resistance and waterproof performance of the membrane are improved.
It effectively resists friction and wear, prevents coating cracks and peeling, absorbs impact energy from sharp objects, disperses stress, improves the integrity and waterproof performance of the waterproof layer, enhances the puncture resistance of the roll material, and is easy to construct.
