Abstract

The invention discloses an anti-radiation computer screen protective film which comprises the following raw materials in parts by weight: 10-25 parts of xanthan gum, 15-35 parts of carrageenan, 2-5 parts of nano titanium dioxide, 3-9 parts of nano zinc oxide, 2-10 parts of rose essential oil, 1.5-3.5 parts of yttrium nitrate, 3-10 parts of a graphene dispersing liquid, 1-4 parts of polyimide resin, 1-3 parts of a diamine monomer and 0.5-3.5 parts of a plasticizer. The invention provides a preparation method of the anti-radiation computer screen protective film. The preparation method is simple and feasible and relatively low in cost. The film is made from natural raw materials, so that the film-forming effect is relatively good. By adding nano titanium dioxide and nano zinc oxide into the raw materials, blue light of the computer screen can be prevented from penetrating through, so that damage to people by radiation can be reduced to a certain extent.

Description

technical field [0001] The invention belongs to the field of computer equipment, and in particular relates to a radiation-proof computer screen protective film and a preparation method thereof. Background technique [0002] In today's society, people rely more and more on computers. Computers are closely related to people's study, life and work, and many people face computer screens most of the day. The working principle of the computer will cause the accumulation of charge on the computer screen, causing adverse consequences such as dust absorption and discharge with surrounding objects. At the same time, the electromagnetic radiation and reflected light generated by the computer, when facing the computer for a long time, the eyes are prone to fatigue, redness, vision loss, and even seriously affect the health of the body, such as dizziness, headache, inability to concentrate, etc. Therefore, developing a radiation-proof computer protective film with simple process, low c...
