High-exhaust anti-static acrylic protective film and preparation method thereof

Abstract

The embodiment of the invention relates to the technical field of materials, in particular to a high-exhaust anti-static acrylic protective film and a preparation method of the protective film. The high-exhaust anti-static acrylic protective film comprises a PET (polyethylene terephthalate) film substrate layer, an acrylic glue layer and a silicon release film layer which are sequentially stacked. With the adoption of the mode, the high-exhaust anti-static acrylic protective film has the characteristic of high transparency, is bound with a screen, has high-exhaust and anti-static performance, can avoid an adverse effect of silicon transfer on the screen, and can prevent static accumulation from damaging an electronic component.

Description

technical field [0001] The embodiments of the present invention relate to the field of material technology, in particular to a high exhaust antistatic acrylic protective film and a preparation method thereof. Background technique [0002] With the rapid development of consumer electronics, various protective films have become an indispensable product for electronic products such as smartphones and tablet computers. [0003] Silicone protective film is widely used due to its superior air release and high temperature resistance, and the peeling force is very stable. However, there is a risk of silicon transfer when the silicone is attached to the screen protector. As time goes on, the risk of silicone transfer to the screen increases. [0004] On the other hand, the existing protective film is generally composed of a substrate layer and an adhesive layer coated on the surface of the substrate layer, wherein the substrate layer is generally made of ordinary polyester film, and...

However, there is a risk of silicon transfer when the silicone is attached to the screen protector. As time goes on, the risk of silicone transfer to the screen is higher

[0004] On the other hand, the existing protective film is generally composed of a substrate layer and an adhesive layer coated on the surface of the substrate layer, wherein the substrate layer is generally made of ordinary polyester film, and ordinary polyester film Film is a kind of high molecular polymer. Although it has the advantages of small dielectric constant, strong insulation and low resistance, it is easy to generate static electricity.

When the above-mentioned protective film is attached to the surface of the glass substrate of the corresponding electronic product, the protective film will easily absorb fine things such as dust and impurities, and even generate static electricity and cause serious losses. Once the static electricity is too large, it will also cause certain damage to the user. the harm of
