MODIFIED PP plastics, described supporting layer uses ldpe resin, and described corona layer uses polyolefin, described heat resistance modified PP
The heat distortion temperature of plastics is 140 °, and described supporting layer sets bilayer thickness, is 500 microns altogether.This utility model provides a kind of new
The novel PE casting films of permeable watertight.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of novel PE casting films, passes through
It is provided with microporous teflon membran and reaches the function of permeable watertight.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of novel PE is cast
Film, including basic unit, described basic unit is provided with binding agent, described binding agent is provided with supporting layer, and described supporting layer is arranged
Having hot sealing layer, described hot sealing layer is provided with corona layer, described corona layer is provided with barrier layer, described supporting course uses poly-four
Fluoride microporous film.
By using technique scheme, basic unit has bonded supporting layer by binding agent, and supporting layer have employed polytetrafluoroethyl-ne
Alkene microporous membrane, poly tetrafluoroethylene is the rod by polytetrafluoroethylextruded extruded molding, band, through being rolled into the semi-finished product of thin film, molten
After the following temperature tensile of point, thermal finalization, the porous article obtained, supporting layer is provided with hot sealing layer, improves hot melt, envelope
Mouth easily, is provided with corona layer on hot sealing layer, has the surface tension of appropriateness, and low cost, is provided with resistance on corona layer
Interlayer so that casting films has good waterproof barrier property.
This utility model is further arranged to: described basic unit uses density polyethylene film with high.
By using technique scheme, density polyethylene film with high is non-hygroscopic, and has good water vapor,
Chemical stability is good, and mechanical strength is relatively good, can effectively cut off passing through of water.
This utility model is further arranged to: described supporting layer is set to bilayer thickness.
By using technique scheme, so that reach preferable water-resisting property, arranging supporting layer is double-decker.
This utility model is further arranged to: described hot sealing layer uses PUR.
By using technique scheme, PUR is a kind of plastic binding agent, its thing in certain temperature range
Reason state changes with temperature and changes, and chemical characteristic is constant, and it is nonpoisonous and tasteless, belongs to environmental-protecting chemical product, is effectively improved heat
Fusibleness.
This utility model is further arranged to: described corona layer uses polyolefin.
By using technique scheme, polyolefin has that relative density is little, chemical proofing, water-tolerant；Well
Mechanical strength, the spy such as electrical insulating property, there is the surface tension of appropriateness, can be easy to again print processing, and low cost.
This utility model is further arranged to: be provided with layer of polyurethane between described hot sealing layer and corona layer.
By using technique scheme, layer of polyurethane is hydrophilic poromeric material, on the one hand can improve the saturating of thin film
Gas, can give again the elasticity of thin film.
This utility model is further arranged to: described barrier layer uses polyvinyl alcohol.
By using technique scheme, polyvinyl alcohol has preferable resistance to water, intercepts passing through of water.
In sum, this utility model has the advantages that the effect with preferable permeable watertight.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment.
In figure: 1, basic unit；2, supporting layer；3, hot sealing layer；4, corona layer；5, barrier layer；6, layer of polyurethane.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, this utility model is described in detail.
A kind of novel PE casting films, as it is shown in figure 1, include basic unit 1, basic unit 1 uses density polyethylene film with high, high density
Polyethylene film is non-hygroscopic, and has good water vapor, and chemical stability is good, and mechanical strength is relatively good,
That can effectively cut off water has bonded supporting layer 2 by basic unit 1 by binding agent, so that reach preferable water-resisting property, if
Putting supporting layer 2 is double-decker, and binding agent can be EVA (vinyl-vinyl acetate copolymer), (ethylene-acrylic acid is common for EAA
Polymers), polyacrylate, one or both in maleic anhydride, supporting layer 2 have employed microporous teflon membran, polytetrafluoro
Vinyl film is the rod by polytetrafluoroethylextruded extruded molding, band, and through being rolled into the semi-finished product of thin film, the temperature below fusing point is drawn
Stretch, after thermal finalization, the porous article obtained, by double-deck setting, reached the performance of preferable water proof, on supporting layer 2
Being provided with hot sealing layer 3, hot sealing layer 3 uses PUR, PUR to be a kind of plastic binding agents, in certain temperature range its
Physical state changes with temperature and changes, and chemical characteristic is constant, and it is nonpoisonous and tasteless, belongs to environmental-protecting chemical product, is effectively improved
Hot melt, sealing easily, is provided with corona layer 4 on hot sealing layer 3, and corona layer 4 uses polyolefin, polyolefin to have relative density
Little, chemical proofing, water-tolerant；The spies such as good mechanical strength, electrical insulating property, have the surface tension of appropriateness, can be just
In again printing processing, and low cost, being provided with layer of polyurethane 6 between hot sealing layer 3 and corona layer 4, layer of polyurethane 6 is hydrophilic
Poromeric material, on the one hand can improve the breathability of thin film, can give again the elasticity of thin film, be provided with on corona layer 4
