In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides an antibiotic ventilated membrane of combined type of high strength, includes waterproof ventilated membrane, non-woven fabrics layer, antibiotic layer, strengthening rib, hot melt adhesive layer, leaves type paper, the upper and lower surface of waterproof ventilated membrane is provided with the non-woven fabrics layer, be provided with antibiotic layer and strengthening rib in the non-woven fabrics layer, the surface bonding on one of them non-woven fabrics layer has hot melt adhesive layer, hot melt adhesive layer's surface bonding has from type paper.
Preferably, the number of the reinforcing ribs is multiple, and the plurality of reinforcing ribs are uniformly distributed in the non-woven fabric layer.
Preferably, the surface of one of the non-woven fabric layers is provided with a sawtooth layer, and the sawtooth layer is bonded with the hot melt adhesive layer.
Preferably, the waterproof breathable film is a polyethylene breathable film, and the thickness of the waterproof breathable film is 0.1 mm.
Preferably, the antibacterial layer is made of nano silver, and the thickness of the antibacterial layer is 0.08 mm.
Preferably, the non-woven fabric layer is a needle-punched non-woven fabric, and the thickness of the non-woven fabric layer is 0.24 mm.
Compared with the prior art, the utility model has the following beneficial effects:
1. according to the utility model, the upper surface and the lower surface of the waterproof breathable film are respectively provided with the non-woven fabric layer, and the antibacterial layer and the reinforcing ribs are designed in the non-woven fabric layers, so that on one hand, the integral strength can be increased, the anti-tearing structure is not easy to tear, and on the other hand, the breeding of bacteria can be inhibited.
2. According to the utility model, the sawtooth layer is arranged on the surface of one of the non-woven fabric layers, so that the contact area between the non-woven fabric layers and the hot melt adhesive layer is larger, the connection between the non-woven fabric layers and the hot melt adhesive layer is further more stable, and the non-woven fabric layers and the hot melt adhesive layer are not easy to degum.
Drawings
FIG. 1 is a perspective view of the overall construction of the present invention;
FIG. 2 is a cross-sectional view of the structure of FIG. 1 in accordance with the present invention;
in the figure: 1. a waterproof breathable film; 2. a non-woven fabric layer; 21. an antibacterial layer; 22. reinforcing ribs; 23. a layer of serrations; 3. a hot melt adhesive layer; 4. and (4) release paper.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, a high-strength composite antibacterial breathable film includes a waterproof breathable film 1, a non-woven fabric layer 2, an antibacterial layer 21, a reinforcing rib 22, a hot-melt adhesive layer 3, and release paper 4, the non-woven fabric layer 2 is disposed on the upper and lower surfaces of the waterproof breathable film 1, the antibacterial layer 21 and the reinforcing rib 22 are disposed in the non-woven fabric layer 2, the hot-melt adhesive layer 3 is bonded on the surface of one of the non-woven fabric layers 2, and the release paper 4 is bonded on the surface of the hot-melt adhesive layer 3.
Referring to fig. 1 and 2, the number of the reinforcing ribs 22 is plural, and the plural reinforcing ribs 22 are uniformly distributed in the nonwoven fabric layer 2. Through the design of the reinforcing ribs 22, the strength of the non-woven fabric can be increased, and the non-woven fabric is not easy to tear.
Referring to fig. 1 and 2, a sawtooth layer 23 is disposed on a surface of one of the nonwoven fabric layers 2, and the sawtooth layer 23 is adhered to the hot melt adhesive layer 3. The design of the sawtooth layer 23 enables the contact area between the non-woven fabric layer 2 and the hot melt adhesive layer 3 to be larger.
