The thermal expansion waterproof layer, the breathable layer and the inner waterproof layer are sequentially arranged from top to bottom and are compounded together by adopting a three-layer co-extrusion technology, the thermal expansion waterproof layer expands after being heated, and after the expansion of the small-particle thermal expansion microspheres, the contact area of the surface of the film is reduced, so that the friction force is reduced, the hand feeling is improved, and meanwhile, the wear-resistant layer is made of wear-resistant plastic or rubber materials, and the wear resistance is improved.
Description
Technical Field
The utility model relates to a ventilated membrane technical field especially relates to super wear-resisting ventilated membrane.
Background
The breathable film is a material widely applied to the field of clothes and hygienic products, the improvement direction of the existing breathable film is mostly developed towards the waterproof and breathable direction, and the waterproof breathable film is more complex than the common breathable film in terms of manufacturing process, higher in technical requirement and better in quality. However, the existing waterproof breathable film has poor wear resistance, is easy to damage and causes cost increase, and meanwhile, the waterproof breathable performance of the existing waterproof breathable film is reduced after abrasion, so that the use experience of a user is influenced, and an improved space exists.
SUMMERY OF THE UTILITY MODEL
For overcoming the technical defect that prior art exists, the utility model provides a super wear-resisting ventilated membrane, including the three-layer crowded complex thermal energy waterproof layer, ventilative layer and the interior waterproof layer that form altogether that set gradually from top to bottom, the upper surface of thermal energy waterproof layer is equipped with the inflation arch, the bellied surface of inflation is equipped with the wearing layer, the bellied height of inflation is 10 mu m-20 mu m.
Furthermore, the air permeable layer is provided with air holes.
Furthermore, the thermal expansion waterproof layer and the inner waterproof layer are both provided with breathable micropores.
Furthermore, the wear-resistant layer is made of plastic or rubber.
Furthermore, the breathable layer is made of PE high-molecular breathable film.
Further, the inner waterproof layer is made of PP materials.
To sum up, the beneficial effects of the utility model are that: the thermal expansion waterproof layer, the breathable layer and the inner waterproof layer are sequentially arranged from top to bottom and are compounded together by adopting a three-layer co-extrusion technology, the thermal expansion waterproof layer expands after being heated, and after the expansion of the small-particle thermal expansion microspheres, the contact area of the surface of the film is reduced, so that the friction force is reduced, the hand feeling is improved, and meanwhile, the wear-resistant layer is made of wear-resistant plastic or rubber materials, and the wear resistance is improved.
Drawings
Fig. 1 is a schematic structural view of the super wear-resistant breathable film of the present invention.
Description of reference numerals:
1. a thermal expansion waterproof layer; 2. a breathable layer; 3. an inner waterproof layer; 4. air holes are formed; 5. an expansion lobe; 6. and a wear-resistant layer.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1, the present embodiment provides a super wear-resistant breathable film, which comprises a thermal expansion waterproof layer 1, a breathable layer 2 and an inner waterproof layer 3.
In this embodiment, the thermal expansion waterproof layer 1, the air permeable layer 2 and the inner waterproof layer 3 are sequentially arranged from top to bottom and are compounded together by adopting a three-layer co-extrusion technology.
In this embodiment, the upper surface of the thermal expansion waterproof layer 1 is provided with expansion protrusions, specifically, the expansion protrusions 5 are formed by thermal expansion microspheres which expand when heated, the surface of the expansion protrusions 5 is provided with a wear-resistant layer 6, the wear-resistant layer 6 is made of plastic or rubber, and the height of the expansion protrusions 5 is 10 μm to 20 μm.
In this embodiment, the breathable layer 2 is made of a PE polymer breathable film, and the breathable layer 2 is provided with the breathable holes 4, so that the breathability of the breathable layer 2 is improved.
In this embodiment, the thermal expansion waterproof layer 1 and the inner waterproof layer 3 are both provided with air permeable micropores.
In this embodiment, the inner waterproof layer 3 is made of PP.
In the above embodiment, thermal expansion waterproof layer 1, ventilative layer 2 and interior waterproof layer 3 set gradually from top to bottom and adopt the three-layer coextrusion technique to compound together, thermal expansion waterproof layer 1 expands after being heated, and the expansion of tiny particle thermal expansion microballon is back, has reduced the area of contact on film surface, and then has reduced the frictional force, has promoted and has felt, and simultaneously, wearing layer 6 adopts wear-resisting plastics or rubber material to make, has promoted the wearability, and setting up micropore 4 on ventilative layer 2 has further promoted the gas permeability.
The foregoing embodiments illustrate and describe the principles and principal features of the invention and advantages thereof, and it will be understood by those skilled in the art that the invention is not limited by the foregoing embodiments, which are merely illustrative of the principles of the invention, but is capable of numerous changes and modifications without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
