The utility model provides a not enough to prior art, the utility model provides a high temperature resistant low temperature resistant PE membrane, including the tie coat, the laminating of tie coat upper wall has high temperature PE membrane, the laminating of tie coat lower wall has low temperature PE membrane, high temperature PE membrane adopts linear low density polyethylene LLDPE material, low temperature PE membrane adopts polyethylene LDPE material, the laminating of high temperature PE membrane upper wall has the water proof membrane.
Preferably, an anti-freezing layer is attached to the lower wall of the low-temperature PE film.
Preferably, the antifreeze is sprayed on the lower wall of the antifreeze layer.
Preferably, the adhesive layer is an adhesive.
Preferably, the thickness of the high-temperature PE film is greater than the thickness of the low-temperature PE film.
Preferably, the tie layer thickness is less than the low temperature PE film thickness.
The utility model discloses following beneficial effect has:
the whole two kinds of PE membrane that have adopted of membrane structure constitutes, the PE membrane of linear low density polyethylene LLDPE material has higher high temperature resistance ability, and polyethylene LDPE material PE membrane has better low temperature resistance ability, consequently can make the membrane body have better high temperature resistant and low temperature resistance ability through the combination, for the membrane body among the prior art, the function is comparatively changeable, and to the weather in different seasons, adaptation that can be fine, thereby increase the application range of PE membrane.
