AI Technical Summary

Problems solved by technology

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 computer produces strong ultraviolet light and low-frequency microwave radiation. 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.
[0003] At present, there are many anti-radiation products to prevent computer radiation, such as anti-radiation computer protective film, etc., but there is no product that can effectively reduce computer ultraviolet radiation.

Embodiment 1

[0015] A computer screen protective film containing rare earth is prepared by the following method:

[0016] (1) Dissolve 5g of polyvinyl chloride powder in 50ml of tetrahydrofuran, then add 2g of benzophenone and 3g of n-dioctyl phthalate and stir well, then add tetrahydrofuran until the total volume of the solution is 100ml, and the mass percentage is 5% polyvinyl chloride solution;

[0017] (2) Add 2g of yttrium rare earth nitrate, 2g of divinylbenzene, 0.1mg of K3 and 0.1mg of T416 to the PVC solution in step (1) and stir evenly until a transparent solution is obtained;

[0018] (3) Pour the transparent solution in step (3) into a glass mold, dry it in vacuum for 7 hours, and release it from the mold.

Embodiment 2

[0020] A computer screen protective film containing rare earth is prepared by the following method:

[0021] (1) Dissolve 5g of polyvinyl chloride powder in 50ml of tetrahydrofuran, then add 3g of benzophenone and 3g of n-dioctyl phthalate and stir evenly, then add tetrahydrofuran until the total volume of the solution is 100ml, and the mass percentage is 5% polyvinyl chloride solution;

[0022] (2) Add 3g of yttrium rare earth nitrate, 2.5g of divinylbenzene, 0.15mg of K3 and 0.15mg of T416 to the PVC solution in step (1) and stir evenly until a transparent solution is obtained;

[0023] (3) Pour the transparent solution in step (3) into a glass mold, dry it in vacuum for 7 hours, and release it from the mold.

Abstract

The invention provides a rare-earth-containing computer screen protecting membrane which is prepared by dissolving yttrium nitrate rare earth, pigment powder and divinyl benzene in a polyvinyl chloride solution and by preparing by using a tape casting method, wherein the pigment powder is a mixture of T416 and VK3 in a mass ratio of 1:1. The rare-earth-containing computer screen protecting membrane provided by the invention is high in transparency, remarkably high in mechanical property, very good in ultraviolet absorption property and capable of effectively preventing damage of ultraviolet light to glasses.

Description

technical field [0001] The invention relates to a computer protective film, in particular to a computer screen protective film containing rare earth. Background technique [0002] Computers are closely related to the lives of modern people, and many people face computer screens most of the day. The working principle of the computer will cause the accumulation of electric charge on the computer screen, causing adverse consequences such as dust absorption and discharge with surrounding objects. At the same time, the computer produces strong ultraviolet light and low-frequency microwave radiation. 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. . [0003] There are many anti-radiation products that prevent computer radiation at present, such as anti-radiation computer protective films, but there are no products that effec...
