Abstract

The invention discloses a PVC protective film having good waterproof property. The PVC protective film includes a protective film body; the interior of the protective film body is provided with an upper film and a lower film, an adhesive layer is arranged between the upper film and the lower film, both sides of the adhesive layer are respectively connected with the lower surface of the upper film and the upper surface of the lower film, and the interior of the upper film is provided with a base body; the upper surface of the base body is bonded with a heat-resistant layer; the upper surface of the heat-resistant layer is bonded with a waterproof layer; the lower surface of the base body is bonded with a glass fiber layer; the lower surface of the glass fiber layer is bonded with a composite fiber layer; the structure of the interior of the upper film is the same as that of the interior of the lower film. The both sides of each of the upper film and the lower film are each provided with a convex edge, and the convex edges can protect a connector, reduce the influence of water vapor on the connector and ensure the stability of connection between the protective film and an object; moreover, if the surface of the protective film makes contact with water, the upper film can be peeled through the upper convex edges, the lower film can still protect the object, and thus the protective film is safer and more convenient to use.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a PVC protective film with good water resistance. Background technique [0002] According to the application, the protective film can be divided into digital product protective film, car protective film, household protective film, food fresh-keeping protective film and so on. With the popularization of digital products such as mobile phones in China, protective film has gradually become a general term for screen protective film, and its functions in the field of screen protective film are also varied, the earliest high-definition scratch-resistant, and now Hong Kong GLAUKE, 180 degrees And the favor of OK8 functional protective film. The material has experienced more than 5 years of development from the earliest PP material to the current popular AR material, and has gradually been accepted by the majority of mobile phone groups. The application range of the protective ...
