Description

Special protective film for tpu four-layer structure special for cutting machine
Technical Field
The utility model belongs to the technical field of the protection film technique and specifically relates to special protection film of special tpu four-layer structure of cutting machine.
Background
the tpu material is short for Thermoplastic Urethane elastomer, herein referred to as Thermoplastic polyurethane elastomer. The TPU is a high molecular material formed by jointly reacting and polymerizing diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or Toluene Diisocyanate (TDI), etc., and macromolecular polyol and low-molecular polyol (chain extender). In the prior art, the tpu material has excellent characteristics and can be applied to a protective film of a cutting machine, but the prior protective film special for the tpu applied to the cutting machine has the following problems: (1) the existing special protection film for the tpu has a simple structure and poor scratch resistance, so that the surface of the cutting machine is easy to damage due to the scratch phenomenon easily occurring in the using process; (2) the existing special protection film for the tpu is easy to have residual glue after being peeled off, so that the cleaning strength of a user is improved; (3) the existing protection film special for the tpu has poor air exhaust performance, and is easy to generate bubbles or generate white edges, so that the use effect of the product is influenced.
Disclosure of Invention
Not enough to prior art, the utility model provides a special protection film of special tpu four-layer structure of cutting machine, this protection film is through improving the back, can effectively solve the problem that proposes in the above-mentioned background art.
The technical scheme of the utility model is that:
the special protection film of special tpu four-layer structure of cutting machine, its characterized in that: it includes the protection film body, the protection film body down bonds in proper order from last has a layer, b layer, c layer and d layer, the layer is from last down to bond in proper order and has prevent scraping layer, first PET substrate layer and acrylic acid adhesive layer, the layer is from last down to bond in proper order and has selfreparing coating, TPU substrate layer and mixed glue film, the layer is from last down to bond in proper order and has first from type layer, second PET substrate layer and silica gel layer, the layer is from last down to bond in proper order and has the second from type layer and white PET layer on the d layer.
Further, the thickness of the scratch-resistant layer is 10 microns, the thickness of the first PET substrate layer is 50 microns, and the thickness of the acrylic acid adhesive layer is 10 microns.
Further, the thickness of the self-repairing coating is 25 microns, the thickness of the TPU substrate layer is 100 microns, and the thickness of the mixed glue layer is 30 microns.
Further, the thickness of first type layer is 10 microns, the thickness of second PET substrate layer is 50 microns, the thickness of silica gel layer is 10 microns.
Further, the thickness of the second release layer is 10 microns, and the thickness of the white PET layer is 100 microns.
The utility model has the advantages that: the utility model discloses a be equipped with and prevent scraping layer and selfreparing coating, can effectively improve the protection film body and prevent scraping the performance, avoid easily appearing scraping broken phenomenon in the use, effectively protect by the protection object surface, moreover, the utility model discloses a protection film adhesion power is good and tear easily, peels off the back and does not have the cull, still has excellent air discharge, prevents its phenomenon that bubble or white limit appear to further improve user's result of use, the practicality is strong, is worth promoting.
