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
