Abstract
The invention provides an anti-radiation computer protective film and a preparation method thereof. The preparation method disclosed by the invention is simple and comprises the following steps: utilizing konjaku flour and carrageenan serving as natural components as film-forming base materials, adding SiO2, modified rare-earth and other materials with anti-radiation characteristics, thereby obtaining the anti-radiation computer protective film which is low in cost and safe to use. The product is high in transparency and high in light transmittance, has excellent mechanical scratch resistance and anti-radiation properties, can be directly attached to a computer screen and is convenient to use.
Description
Technical field
The present invention relates to a kind of computer protection film, be specifically related to a kind of radiation proof computer protection film and preparation method thereof.
Background technology
The study of computer and people, life and and close the contacting that work, a lot of people most of the time of one day facing to computer screen.The principle of work of computer can cause stored charge on computer screen, causes attract dust, with adverse consequencess such as surrounding objects electric discharges.Meanwhile, electromagnetic radiation light, reflected light that computer produces, when for a long time in the face of computer, eyes are easily tired, rubescent silk, and visual deterioration even has a strong impact on healthy, as dizziness, headache, absent minded etc.
Sell several functions computer protection film etc. in the market; but these products are mostly to prevent screen from scratching or collision cleft; possess anti-electrostatic, radiation proof function computer protection film product also little, and the shortcoming such as its product preparation process is complicated, price is high, effect is low.
Summary of the invention
The invention provides a kind of cheap, radiation proof computer protection film that use safety, radiation-proof effect are good and preparation method thereof.
Technical scheme of the present invention is as follows:
A kind of radiation proof computer protection film, prepares as follows:
(1) by Rhizoma amorphophalli powder and carrageenin, join in distilled water, 60-80 DEG C of stirring and dissolving, obtain transparent adhesive tape solution, in transparent adhesive tape solution, the mass percentage concentration of Rhizoma amorphophalli powder and carrageenin is respectively 4-8% and 3-6%;
(2) in the transparent adhesive tape solution of step (1), Yttrium trinitrate rare earth and SiO is added
2after stir, with NaOH, solution ph is adjusted to 9, continue to stir 1-3 hour under 70-80 DEG C of constant temperature, cool to room temperature, obtains film liquid;
(3) by the film liquid of step (2) through whizzer, after degassed, pour in sheet glass mould, at 40-45 DEG C of vacuum-drying 4-8 hour, be cooled to room temperature, place 6-12 hour, by film lift-off stencil;
(4) film of stripping is cut into different sizes, packaging.
In the present invention, be 1-3% in the concentration of the Yttrium trinitrate rare earth described in step (2) in described film liquid.
In the present invention, in the SiO described in step (2)
2concentration in described film liquid is 0.2-0.4%.
In the present invention, the particle diameter of described Yttrium trinitrate rare earth is 50-100nm.
Beneficial effect of the present invention: preparation method of the present invention is simple, is utilize as the Rhizoma amorphophalli powder of natural component and carrageenin as film forming binder, and adds SiO
2with modified RE etc., there is the material of radioprotective characteristic, prepare radiation proof computer protection film that is with low cost, use safety.This product transparency is high, and transmittance is good, but also has the scuffing of good resistance to mechanical and anti-radiation, and directly can be affixed on computer screen and use, application is convenient.Also have degradable performance, be a kind of product of environmental protection simultaneously.
