Description

A kind of toughening type air permeable waterproof laminated film

Technical field

The utility model belongs to function film technical field, and in particular to a kind of toughening type air permeable waterproof laminated film.

Background technique

Waterproof ventilated membrane is a kind of novel high polymer waterproof material.From manufacture craft, the technology of waterproof ventilated membrane It is required that higher than general waterproof material is more；Simultaneously from quality, waterproof ventilated membrane also has other waterproof material institutes The functional characteristics not having.

The technology of waterproof ventilated membrane is to introduce since American-European countries, however the manufacture craft five of home products is spent earliest Eight, the product quality of each producer is irregular, could not form a unified quality standard.Breathable films at present, by carbon The irregular mixing material being distributed in PE film of sour calcium particle, 0.5 micron~10 microns of diameter.When breathable films are thin micro- to 15 When rice~20 microns, part calcium carbonate particle can protrude from former PE film surface, until breathable films is made fracture, the feelings such as junk occur Condition, toughness are poor；Increase air permeable waterproof while improving toughness and antibiotic property is extremely important.

Therefore researching and developing one kind has waterproof and breathable, and the strong toughening type air permeable waterproof laminated film not easy to break of toughness is very It is necessary.

Utility model content

In view of the problems of the existing technology, the purpose of this utility model is to provide a kind of toughening type air permeable waterproof is compound Film.The novel toughening type air permeable waterproof laminated film of the utility model has waterproof and breathable, the strong advantage not easy to break of toughness.

In order to solve the above technical problems, the technical solution adopted in the utility model is.

A kind of toughening type air permeable waterproof laminated film, including upper layer, chitosan anti-bacteria layer, the first PE ventilative film layer, second Breathe freely film layer, the 3rd PE of PE breathes freely film layer, nanometer silver antimicrobial layer and lower layer, and successively compound in order, it is poly- that shell is pasted on the upper layer Sugared antibiotic layer, the chitosan anti-bacteria layer paste the first PE and breathe freely film layer, and the first PE breathes freely compound 2nd PE of film layer Ventilative film layer, the ventilative film layer of ventilative compound 3rd PE of film layer of the 2nd PE, the ventilative film layer composite nano silver of the 3rd PE are anti- Bacterium layer, the compound lower layer of nanometer silver antimicrobial layer.

The antibacterial agent of a kind of preferred embodiment of the utility model, the chitosan anti-bacteria layer addition is carboxymethyl chitosan.

Further, the nanometer silver antimicrobial layer can also add nano zine oxide antibacterial granule.

Further, the 2nd PE breathes freely, and film layer is interior to add nano-calcium carbonate particles.

Further, the 2nd PE breathe freely film layer in addition nano-calcium carbonate particles with a thickness of 16-20 μm.

Further, the first PE breathe freely film layer and the 3rd PE breathe freely film layer with a thickness of 5-10 μm.

Further, the overall thickness of the film is 60-100 μm.

Another preferred embodiment of the utility model, the upper layer and the lower layer are Biaxially oriented polypropylene layer, thickness It is mutually all 5-12 μm.

The beneficial effects of the utility model.

(1) the utility model antibacterial film adds nano-sized carbon using the ventilative film layer of three layers of PE and in the ventilative film layer of middle layer PE Sour calcium particle has and can breathe freely but waterproof effect, while situations such as be not in fracture, junk.

(2) the utility model antibacterial film using upper and lower level Biaxially oriented polypropylene layer cooperation air-permeable layer and adds a variety of anti- The structure of the antibiotic layer of bacterium particle effectively extends fresh keeping time, and the antibacterial effect time is long.
