Technical Field

The application relates to a self-repairing protective film, in particular to a self-repairing protective film with a flame-retardant function.

Background

The wear resistance and the surface hardness of the plastic film are not high, the surface of the plastic film is easy to scratch after long-term use to influence the optical transparency, the decoration performance and other performances, and in order to solve the problem of poor wear resistance of the plastic film, the surface of the plastic film is mainly hardened at the present stage, and a hardened layer is mainly coated on the surface of the plastic film by a wet method.

The general hardening treatment of the surface of the conventional plastic film is helpful for reducing the degree of surface scratches and prolonging the service life, but the surface scratches caused by contact or friction with sharp objects cannot be reversibly restored or repaired, thereby affecting the service life. Therefore, a self-repairing protective film having a flame retardant function has been proposed to solve the above problems.
