Honeycomb Structure Nonwoven Reinforcing Fabric for Waterproof Membrane

Abstract

The invention discloses a honeycomb-structure non-woven reinforced cloth applied to a waterproof roll. Chopped polypropylene fibers are fed into an unpacking opening machine to be opened, are carded by a carding machine and are spread by a lapping machine to form a fiber web; the fiber web is fed into a pre-needling machine to be subjected to secondary needing reinforcement to obtain a nonwoven fabric; the nonwoven fabric is fed into an ultrasonic knurling machine to be subjected to regular hexagon knurling machining to obtain a primary honeycomb-structure reticular nonwoven fabric, wherein regular hexagon bodies are arranged and distributed on the surface of the nonwoven fabric; the nonwoven fabric is fed into a mesh-type metal conveyance curtain to be subjected to wind suction and sizing; a polypropylene hot rolling nonwoven fabric and a primary honeycomb-structure reticular nonwoven fabric are commonly fed into a needling machine to be subjected to needling composite sizing in a selected disorder needling mode to form regular-hexagon-shaped edge-transparent nonwoven reinforced cloth; finally the nonwoven reinforced cloth is fed into a coiler to be coiled, is packaged and is put in storage. According to the honeycomb-structure non-woven reinforced cloth, transparent edge parts can be regularly exposed when the reinforced cloth is compounded with a waterproof sheet, and a water-seepage chain is cut off, so that the waterproof and seepage-proof performances of the waterproof material are improved.

Description

technical field [0001] The invention belongs to the technical field of building waterproofing engineering, and relates to a nonwoven fabric used for waterproof rolls, in particular to a honeycomb structure nonwoven reinforced fabric used for waterproof rolls. Background technique [0002] At present, the surface composite fabrics used for polyethylene polypropylene composite waterproof rolls and polymer reinforced composite sheets are mostly polypropylene long-fiber hot-rolled or polypropylene short-fiber needle-punched non-woven fabrics, which are combined with non-woven fabrics and waterproof sheets. Due to the loose surface of these two kinds of nonwoven fabrics, it has the characteristics of water permeability and water conduction. Therefore, in the process of waterproof construction, the bonding and lap sealing of such waterproof membranes are realized by impermeable adhesives, and the waterproof membranes and the impermeable adhesives together form a waterproof layer. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the above-mentioned shortcoming of existing waterproof roll material, provide a kind of honeycomb structure non-woven reinforced cloth for waterproof roll material, this honeycomb structure non-woven reinforced cloth makes the polymer sheet waterproof layer of waterproof roll material regular Exposure, the seepage chain is cut off, which solves the possibility of leakage in the overlapping seal of this kind of material, and improves the waterproof and anti-seepage performance of this kind of waterproof material
