Safety film and preparation method thereof

Abstract

The invention discloses a safety film and a preparation method thereof. The safety film comprises a base layer of a PET polyester film coated with an anti-stick coating, a UV absorbing layer, an adhesive layer, a safety layer, a composite pressure-sensitive glue layer, a release film layer and Anti-scratch layer, the PET polyester film base layer is used for bonding with glass. The present invention utilizes multi-layer polyethylene materials composed of polymers and long-ring molecules to be compounded, and the biaxially stretched PET polyester film maximizes the rigidity and strength of polymer molecules; the UV absorber prevents ultraviolet rays from harming the human body It is made of a safety film with the effect of absorbing extremely high impact force; and the preparation process is simple, the material is convenient, and the cost is low.

Description

technical field [0001] The invention relates to the field of films, in particular to a safety film and a preparation method thereof. Background technique [0002] As we all know, glass is very fragile, and ordinary glass cannot withstand the damage caused by the following situations: strong winds, earthquakes, explosions, terrorist bombs, industrial accidents (chemical, petroleum, nuclear energy, natural gas, etc.), burglary, forced entry, or everything else External destructive force; and the glass installed on tall buildings will also cause glass damage due to its own weight, excessive heat absorption (solar heat), excessive bending (such as strong wind), excessive shaking of buildings (such as earthquakes), accidental impact, etc. Fragmentation, and the damage derived from the shattering of high-altitude glass is quite large. The safety film of prior art is generally heat-insulating, anti-ultraviolet, common explosion-proof, generally does not have super-strong shock res...

AI Technical Summary

Problems solved by technology

The safety film of prior art is generally heat-insulating, anti-ultraviolet, common explosion-proof, generally does not have super-strong shock resistance, anti-breaking characteristic, and commercially available explosion-proof film mostly is single-layer PET polyester film (PET polyester film, and It is called high-temperature-resistant polyester film), and there are many problems such as not being resistant to breakage and not being earthquake-resistant. In the contemporary era where environmental problems are prominent, new environmentally friendly materials have been favored by more people.
