Composite self-adhering water-proof coiled material

Abstract

The invention relates to a composite self-adhesive waterproof coiled material and belongs to the technical field of building anti-leakage facility. The composite self-adhesive waterproof coiled material comprises an reinforcing layer for forming meshes; the surface of one side of the reinforcing layer is combined with a first waterproof layer; the surface of the other side of the reinforcing layer is combined with a second waterproof layer; the face-to-face sides of the first waterproof layer and the second waterproof layer penetrate the meshes, cross together and wrap the reinforcing layer; the surface of one side of the first waterproof layer or the second waterproof layer back to the reinforcing layer is combined with a self-adhesive layer; and the surface of the self-adhesive layer is combined with an isolation layer. The composite self-adhesive waterproof coiled material has the following advantages: as the reinforcing layer is positioned between the first waterproof layer and the second waterproof layer, the effects of breaking and tearing resistance can be improved; the first waterproof layer and the second waterproof layer can penetrate the meshes of the reinforcing layer to realize perfect combination; therefore, no separation does not occur for a long time; because the self-adhesive layer is combined on the surface of the first waterproof layer or on the surface of the second waterproof layer, and the isolation layer is combined on the self-adhesive layer, the composite self-adhesive waterproof coiled material has the advantages of convenient laying and easy overhauling.

AI Technical Summary

Problems solved by technology

The waterproof membrane of this structure can eliminate the slow and cumbersome construction of the aforementioned waterproof membrane, but the colloid reinforcement layer between the upper and lower flexible waterproof base material layers will cause damage to the upper and lower flexible waterproof base material layers. Artificial separation leads to separation, which affects the integrity of the overall structure; in addition, the waterproof membrane of this structure will not show ideal tensile strength, elongation and elasticity, and will be affected by the main structure of the building. Arching or cracking due to subsidence or cracking; lack of sealing and self-healing properties and convenience of maintenance
