Optical grade hydrophobic and oleophobic antifouling anti-blue-ray screen protector

Abstract

The invention relates to an optical grade hydrophobic and oleophobic antifouling anti-blue-ray screen protector. A first refractive material layer with a high refractive index and a second refractivematerial layer with a low refractive index are arranged between a base material layer and a protective layer, so that the light transmittance performance of the protector is increased, and the light transmittance reaches 98% or higher; a blue absorber is integrated into an upper PET (Polyethylene Terephthalate) protective layer, the anti-blue-ray effect of the protector is greatly improved, and the rejection rate of harmful blue rays reaches 83% or higher; biodegradable environmental-friendly silicone pressure sensitive adhesive layers are coated on the upper and lower surfaces of the base material so as to serve as release agent layers; non-toxic and environmental-friendly PMA (Propylene Glycol Methyl Ether Acetate), PGDA (Propylene Glycol Diacetate) and ethyl acetate are adopted as solvents, so that the screen protector is environmental-friendly, non-toxic and free of pollution; release force between the release film and the base material is light, and the screen protector is easy totear and free of residues; and the protector disclosed by the invention has excellent antibacterial property, wear resistance, scratch resistance and hydrophobic and oleophobic fingerprint-proof effects, and various performance indexes reach the standards.

Description

technical field [0001] The invention belongs to the technical field of protective films, and relates to an optical-grade hydrophobic, oil-repellent, anti-fouling, anti-blue light screen protective film. Background technique [0002] The protective film is a film used to protect the damaged surface. Its purpose is to prevent the surface of the protected substrate from being damaged or polluted during transportation, assembly or processing. The protective film is always attached to the surface of the protected substrate. With the development of electronic technology products, especially the continuous improvement of high-end electronic product screens, semiconductors, and FPC / PCB circuit board technology, the requirements for surface packaging protection and process processing protection continue to increase, especially for the flexibility of its protective materials , Stiffness, weather resistance, cleanliness and stability requirements are continuously upgraded.

Problems solved by technology

With the development of electronic technology products, especially the continuous improvement of high-end electronic product screens, semiconductors, and FPC / PCB circuit board technology, the requirements for surface packaging protection and process processing protection continue to increase, especially for the flexibility of its protective materials , Stiffness, weather resistance, cleanliness and stability requirements are continuously upgraded. Modern flat panel displays, TFT film screens, LEDs, fluorescent lamps and liquid crystal displays all have backlight sources, and the light sources excited by the powerful electron flow have abnormally high Blue light, which is an important part of visible light, includes high-energy short-wave blue light of 380nm-410nm that is harmful to the human body and short-wave blue light of 420-500nm that is beneficial to the human body. High-energy short-wave blue light has extremely high energy and can penetrate the lens directly. Retina, leading to aging of the retinal pigment epithelium, which leads to a lack of nutrients for the light-sensitive cells and causes vision loss

Existing optical protective films have relatively simple functions. The anti-blue light protective films in the prior art usually have low anti-blue light effects or filter out short-wave blue light of 420nm-450nm that is beneficial to the human body.
