Description

Technical Field

[0001] The utility model relates to the field of non-woven fabrics, in particular to a waterproof non-woven fabric. Background Art

[0002] Non-woven fabric, also known as non-woven fabric, is made of directional or random fibers. It is a new generation of environmentally friendly materials with the characteristics of moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich colors, low price, and recyclable. For example, polypropylene pellets are mostly used as raw materials, and are produced by a continuous one-step process of high-temperature melting, spinning, laying, and hot pressing and winding. It is called cloth because it has the appearance and certain properties of cloth. The existing non-woven fabrics on the market not only have a single function, but also have low strength and cannot meet the needs, and are in urgent need of improvement. Utility Model Content

[0003] The utility model aims to provide a waterproof non-woven fabric, which is used to solve the problem that the existing non-woven fabric not only has a single function but also has a low strength and cannot meet the needs.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0017] like Figures 1 to 3 In the embodiment of a waterproof non-woven fabric of the utility model shown, it includes a central skeleton layer 10 and a composite non-woven fabric layer 20 symmetrically bonded to both sides of the central skeleton layer 10. The composite non-woven fabric layer 20 includes a non-woven fabric substrate 21, a waterproof breathable membrane 22, an anti-corrosion membrane 23 and a wear-resistant masking paper 24 from the inside to the outside. Specifically, by arranging the central skeleton layer between the composite non-woven fabric layers, the overall structural strength of the non-woven fabric layer can be greatly improved, which is convenient for the staff to lay; the waterproof breathable membrane and the anti-corrosion membrane can be used for waterproofing and anti-corrosion, which not only improves the scope of use of the non-woven fabric, but also extends the service life of the non-woven fabric; the wear-resistant masking paper can protect the surface of the anti-corrosion membrane during laying to avoid damage during construction.

[0018] In one embodiment of the present application, the material of the central skeleton layer 10 is rubber.

[0019] In one embodiment of the present application, the central skeleton layer 10 is formed by evenly splicing a plurality of hollow hexagonal bases 101, and a plurality of strong glue application points 102 are fixed on both sides of each hexagonal base 101. Specifically, since the hexagon has good structural stability, the central skeleton layer 10 can improve the overall tensile strength and structural strength of the non-woven fabric; the multi-point gluing method greatly reduces the use of glue and reduces production costs compared to the traditional large-area gluing method.

[0020] In one embodiment of the present application, the thickness of the central skeleton layer 10 is 1 mm-2 mm.

[0021] In one embodiment of the present application, the waterproof breathable membrane 22 has a thickness of 0.5 mm-1 mm.
