Wherein, have simultaneously release liners or PET film to send between two pinch rollers from the extruder die head opposite side, final cooling is batched and is obtained release liners-TPU-release liners or PET-TPU-PET composite membrane.
Wherein, the film that release liners consists of is sent into from a side of extruder die head, batches through a pinch roller, and the film of PET formation is sent into from the opposite side of extruder die head simultaneously, batch through another pinch roller, the tow sides that are compounded in respectively the TPU buildup after pressing are obtained release liners-TPU-PET composite membrane.
Wherein, the film that release liners consists of is sent into from a side of extruder die head, with the TPU buildup to after pressing, send between other two pinch rollers, the film that consists of with PET carries out second time to pressing, and obtains release liners-TPU-PET composite membrane thereby the film of the film that release liners is consisted of and PET formation is compounded in respectively the tow sides of TPU buildup.
Wherein, the film that PET consists of is sent into from a side of extruder die head, with the TPU buildup to after pressing, send between other two pinch rollers, the film that consists of with release liners carries out second time to pressing, and obtains release liners-TPU-PET composite membrane thereby the film of the film that PET is consisted of and release liners formation is compounded in respectively the tow sides of TPU buildup.
Wherein, the TPU buildup that die head is flowed out is to being pressed in before the film surface, first through two other pinch roller to pressing and cooling.
In addition, described two pinch rollers are respectively main pinch roller and embossed wheel.
In addition, described main pinch roller can be ganoid rubber wheel or iron tyre, and described embossed wheel can be the surface and establishes dapple rubber wheel or iron tyre.
The invention has the beneficial effects as follows: according to the composite membrane of this manufacture method processing, have the advantage of TPU and PET/ release liners concurrently, because of TPU product resilient enough, this TPU composite membrane can not be out of shape and make dirty when being used for printing processing and other back segments processing processing, and easy to process.
