Abstract
The invention provides an anti-radiation membrane material for computers. The material is characterized by comprising the following components in percentage by mass: 5-8 percent of konjaku flour, 3-6 percent of carrageenan, 1-3 percent of modified rare-earth, 0.4-0.8 percent of TiO2 and 0.1-0.3 percent of copper powder. The anti-radiation membrane material, which is low in coat, safe to use and used for computers is prepared from natural ingredients konjaku flour and carrageenan serving as membrane base materials in addition to titanium dioxide, copper powder, modified rare-earth and other materials with anti-radiation characteristics. The anti-radiation membrane material has high transmittance, good light transparency, good mechanical scratch resistance and radiation resistance.
Description
Technical field
The present invention relates to a kind of mould material, be specifically related to a kind of computer radiation prevention film material.
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, computer radiation prevention film material that use safety, radiation-proof effect are good.
Technical scheme of the present invention is as follows:
A kind of computer radiation prevention film material, comprises following component by mass percentage: Rhizoma amorphophalli powder 5-8%, carrageenin 3-6%, remodeling rare earth 1-3%, TiO
20.4-0.8%, copper powder 0.1-0.3%.
In preferred technical scheme, computer radiation prevention film material of the present invention, comprises following component by mass percentage: Rhizoma amorphophalli powder 6%, carrageenin 4%, remodeling rare earth 1.5%, TiO
20.5%, copper powder 0.2%.
In the present invention, described computer radiation prevention film material also comprises zinc oxide 0.2-0.5%.
In the present invention, described modified RE is Yttrium trinitrate rare earth.The particle diameter of further described Yttrium trinitrate rare earth is 50-100nm.
In the present invention, the particle diameter of described copper powder is 50-100nm.
Beneficial effect of the present invention: the present invention utilizes as the Rhizoma amorphophalli powder of natural component and carrageenin as film forming binder, and add titanium dioxide and, copper powder and remodeling rare earth etc. have the material of radioprotective characteristic, prepare computer radiation prevention film material 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.Also have degradable performance, be a kind of product of environmental protection simultaneously.
