Description
Technical field
This utility model relates to a kind of thin film, particularly to a kind of TPU film.
Background technology
TPU membrane is a kind of thermoplastic polyurethane.Also it is a kind of environmental protection macromolecule polymer simultaneously.It has nontoxic, wear-resisting
Etc. feature.
TPU film is widely used in making warmhouse booth, and warmhouse booth has insulation, waterproof feature.But, make
During with, if running into sleety weather, it easily gathering more rainwater, accumulates in the rainwater on booth and booth can be made to hold
Carrying more pressure, long use then can promote the situation that booth subsides.
Summary of the invention
The deficiency existed for prior art, this utility model provides a kind of gets rid of surface area water, simple in construction
TPU film.
For achieving the above object, this utility model provides following technical scheme: a kind of TPU film, includes polyurethane
Body layer and the base fabric with the bonding of polyurethane body layer, it is characterised in that: described polyurethane body layer bonds relative to base fabric
The end face of the other end of one end is provided with waterproof membrane, the outer surface of this waterproof membrane offers several towards waterproof membrane
The drainage channel of inner recess, the inwall of drainage channel is provided with some projections.
Use technique scheme, by arranging waterproof membrane on polyurethane body layer, and offer in waterproof membrane
Drainage channel, makes hydrops quickly can discharge along drainage channel, and it is unnecessary to be not accumulated in waterproof membrane causing booth
Pressure, thus extend the service life of booth；Being disposed to of drainage channel internal projection prevents foreign material to be in drainage channel
Inside cause the blocking of drainage channel.
This utility model is further arranged to: each drainage channel in waterproof membrane is confluxed by busway respectively, anti-
The edge of water barrier film is provided with and the outlet of busway conducting.
Use technique scheme, it is fast that drainage speed is so set, simple in construction, easy to process.
This utility model is further set to: be provided with resistance to compression layer between polyurethane body layer and base fabric, this resistance to compression layer bag
Include foam-filled body and be located at foam filled internal and that cross section is in " S " shape Elastic plastic-rubber bar.
Use technique scheme, the bearing strength that can improve TPU film is so set.
Below in conjunction with the accompanying drawings this utility model is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is that the A of Fig. 1 is to schematic diagram.
Detailed description of the invention
A kind of TPU film as shown in Figure 1 and Figure 2, include polyurethane body layer 1 and with polyurethane body layer 1 bonding
Base fabric 2, polyurethane body layer 1 is provided with waterproof membrane 3 relative to the end face of the other end bonding one end with base fabric 2, and this is waterproof
Several drainage channels 31 towards waterproof membrane 3 inner recess, the inwall of drainage channel 31 is offered on the outer surface of barrier film 3
It is provided with some protruding 311.In such scheme, by arranging waterproof membrane 3 on polyurethane body layer 1, and in waterproof membrane 3
On offer drainage channel 31, make hydrops quickly can discharge along drainage channel 31, be not accumulated in waterproof membrane 3 booth is made
Become unnecessary pressure, thus extend the service life of booth；Being disposed to of drainage channel 31 internal projection 311 prevents miscellaneous
Thing causes the blocking of drainage channel 31 in being in drainage channel 31.Will not directly and draining when foreign material are in drainage channel 31
The inwall laminating of passage 31, but held up by protruding 311, foreign material just can be discharged by the medium in drainage channel 31 when flowing.
In this utility model embodiment, in order to further accelerate drainage speed, each drainage channel in waterproof membrane 3
31 are confluxed by busway 32 respectively, and the edge of waterproof membrane 3 is provided with and the outlet 33 of busway 32 conducting.
In order to improve the bearing strength of TPU film, between polyurethane body layer 1 and base fabric 2, it is provided with resistance to compression layer 4, this resistance to compression
Layer 4 includes foam-filled body and is located at foam filled internal and that cross section is in " S " shape Elastic plastic-rubber bar 41.This utility model
Waterproof membrane 3 in embodiment can be PE waterproof membrane.
Claims (3)
