Abstract
This invention provides a special composite material used for screening electromagnetic wave radiation. In the prodn, graphite powder and carbonyl iron are proportionally mixing, then proportionally and thoroughly mixed with high molecular solvent coating or lacquer to produce coating-like or lacquer-like product. According to the difference of electromagnetic wave frequency bands and the requirements of attenuation ratio, the thickness of said product coated on the object needing the screening by spraying is ranged 0.3-3 mm. The product can screen electromagnetic wave at its frequency band of 10 MHz-5,000 MHz, the electromagnetic wave attenuation ratio of 10 dB-40 dB.
Description
Technical field
The present invention relates to the brand-new material that a kind of anti-electromagnetic-radiation pollutes.It can purify and set up healthy solenoid ripple space-time, ensures that especially human body and electrical equipment preserve from and disturb.
Background technology
Aspect electromagnetic wave proof, adopted is the reflection of electromagnetic wave material more, though this method has solved the protective effect to certain object, certainly will cause electromagnetic secondary pollution again at present.
Summary of the invention
In order to overcome the secondary pollution that existing shielding electromagnetic wave material is caused, the invention provides the extraordinary matrix material of a kind of anti-electromagnetic-radiation.This material can absorb hertzian wave, no reflection events, non-secondary pollution, and absorption band is wide, the decay strong, is needing on the object of shielding electromagnetic wave, can be coated with, spray, brush easy to use.
The technical solution used in the present invention is: insert thorough mixing in paint or the coating by Graphite Powder 99 and carbonyl iron dust by formula rate, the weight ratio of Graphite Powder 99 and carbonyl iron dust is 9: 1, and the weight ratio of Graphite Powder 99, carbonyl iron dust and coating or paint is 5: 5.According to the law of conservation of energy principle, utilize the principle of energy transformation, absorption of electromagnetic wave is converted to heat energy, be dispersed into the space, reach thermal equilibrium.
Embodiment
The extraordinary matrix material of anti-electromagnetic-radiation is to be functional materials by Graphite Powder 99 and carbonyl iron dust, cooperate macromolecule solvent coating or paint to mix, the carbonyl iron dust thorough mixing of Graphite Powder 99 and mean particle size≤3.5um, weight ratio is 9: 1, Graphite Powder 99, carbonyl iron dust mix and macromolecule solvent coating or paint again that the thorough mixing weight ratio is 5: 5, make coating shape, paint shape, according to the difference of shielding electromagnetic band, brush, spray, be coated on the object that will shield, thickness is 0.3mm-3mm.
This material shielding electromagnetic wave frequency band is 10MHz-5000MHz, electromagnetic wave attenuation 10dB-40dB.
Claims (3)
1, the extraordinary matrix material of a kind of anti-electromagnetic-radiation, be by weight 9: 1 thorough mixing by Graphite Powder 99 and carbonyl iron dust, through macromolecule solvent coating or paint thorough mixing, Graphite Powder 99, carbonyl iron dust and macromolecule solvent coating, paint weight ratio 5: 5 are made coating shape or paint shape again.
2, according to the extraordinary matrix material of claim 1 described anti-electromagnetic-radiation, it is characterized in that: the shielding electromagnetic wave frequency band is 10MHz-5000MHz, electromagnetic wave attenuation 10dB-40dB.
3, according to claim 1 or the extraordinary matrix material of 2 described anti-electromagnetic-radiations, it is characterized in that can brush, spray, be coated on the object that will shield according to different objects, thickness is 0.3mm-3mm.
