Description

The present invention relates to a screen protection film structure that is bonded to a screen surface and naturally recovers (automatic repair) even if the screen is damaged, thereby ensuring normal viewing.

Currently, many people use electronic products having touch-controlled screens. In order to protect the screen from being damaged by foreign substances, it is common to protect the screen by applying a single protective film on the screen surface.

Conventional protective films generally include a film body, an adhesive layer bonded to one surface of the film body, and a release layer bonded to one surface of the adhesive layer. The adhesive layer is used for adhering to the screen surface of an electronic product, and the release layer is used for protecting the adhesive layer in an unused state. When using the said protective film, the said release layer is peeled off and the said film main body is stuck on the screen surface from the said adhesion layer. The protective film at least beautifies the product, does not leave an adhesive on the screen surface, can be re-applied many times, and has functions such as antifouling properties, scratch resistance, and high permeability.

However, in view of manufacturing costs, each manufacturer selects a low-cost material from the majority of manufacturers. For example, polyethylene terephthalate (abbreviated as PET), polycarbonate (abbreviated as PC), ortho-phenylphenol (abbreviated as OPP), unstretched polypropylene (Casting Polypropylene, abbreviated as CPP), polyethylene glycol terephthalate (Glycol-Polyethylene) Terephathalate (abbreviated as PETG). These achieve the basic functions described above, but these materials have low protective properties, and even a slight scratch can form a pattern on the screen surface, making it impossible to view normally. In particular, when a user walks or goes out and puts an electronic product in a portable bag or pocket, it is damaged by objects such as keys, coins, wristwatches, rings, or dust, and when the damage spreads, the protective film The protective function will expire.

Therefore, the present inventor considered that the above-described drawbacks can be improved, and as a result of intensive studies, the present inventor has arrived at a proposal of the present invention that effectively improves the above-described problems with a rational design.

A layer, an antifouling layer coated on the UV antifouling layer, and an adhesive layer that is installed under the shielding layer and is bonded to the surface of the screen of the electronic product. .

As a result, when the screen protection film structure is used on the screen surface of various electronic products, the UV antifouling layer absorbs the impact and recovers minor scratches naturally, effectively protecting the screen from being damaged. To achieve the effect and to maintain the original visual effect.

Preferably, the composition component of the UV antifouling layer includes a urethane acrylate and monomer having an occupation ratio of 36 to 40% and a methyl isobutyl ketone having an occupation ratio of 25 to 29%. Methyl ethyl ketone having an occupation ratio of 25 to 29%, Propylene glycol monomethyl ether having an occupation ratio of 6 to 8%, and an additive having an occupation ratio of 1 to 3% (Additives) ).

Preferably, the thickness of the UV antifouling layer is in the range of 100 to 300 μm.

Preferably, the thickness of the plastic layer is in the range of 0.08 to 0.7 mm.

Preferably, the thickness of the above-mentioned shielding layer is in the range of 50 to 120 μm.

Preferably, the above-described screen protection film structure further includes at least one opening portion that is installed on a surface other than the punched area.

According to the present invention, a multilayered composite structure is combined with a thin elastic body composed of specific components to achieve impact absorption and self-supporting repair effects.
