AI Technical Summary

Problems solved by technology

Although PVC film is soft and easy to process, it has poor transparency, average water vapor transmission rate, poor weather resistance, and poor flame retardant effect.
PVF film has good weather resistance, but the barrier water vapor permeability is average, and the flame retardant effect of transparent PVF film is poor

Abstract

The invention discloses an ethylene chlorotrifluoroethylene copolymer protection film, which is formed by compounding three layers of an ethylene chlorotrifluoroethylene copolymer film layer, an adhesive layer and a release film layer, or five layers of an ethylene chlorotrifluoroethylene copolymer film layer, an adhesive layer, an ethylene chlorotrifluoroethylene copolymer film layer, an adhesivelayer and a release film layer. According to the present invention, the ethylene chlorotrifluoroethylene copolymer protection film is suitable for the protection of the metal, the cement, the glass and the exterior wall of buildings.

Description

technical field [0001] The invention belongs to the field of macromolecule processing, and relates to a polymer protective film that can be used in buildings, in particular to a protective film containing ethylene chlorotrifluoroethylene copolymer. Background technique [0002] In industrial areas or coastal areas, due to the impact of acid gases such as sulfur dioxide in the air, salt moisture, and wind and sand on buildings and their attachments, the corrosion rate is accelerated, the service life is shortened, and the surface of the building is easy to accumulate dust. Dust, dust, When rainwater and sulfur dioxide or salt gather together, electrochemical reactions are prone to occur, making the surface of the building more likely to be corroded, and the service life is affected [0003] The commonly used building protective films are PET film, PVC film and PVF film. PET film has good mechanical properties and flame retardancy, but the film is relatively hard, it is not e...
