Abstract
The position of external antenna is changed from one side to central area. The graphite powder and carbonyl iron dust mixed with high molecular material is coated at the inside of case and inside of antennal folder. The thickness is 0.3mm-3mm. The electromagnetic wave shielded by the material is 10MHZ-5000MHZ. The radiation to header from antenna is reduced 10db-40db.
Description
Technical field
The present invention relates to a kind of suction ripple environmental protection mobile phone, it can purify and set up healthy solenoid ripple space-time, ensures that especially human body head is not injured by electromagnetic radiation of mobile telephone.
Background technology
At present handset antenna radiation there be not a kind of effective shielding means and method to the electromagnetic wave of head direction.
Summary of the invention
In order to solve electromagnetic radiation of mobile telephone human body head is preserved from, the invention provides the extraordinary composite material of a kind of anti-electromagnetic-radiation.This material can absorb electromagnetic wave, areflexia, non-secondary pollution, and absorption band is wide, the decay is strong, is used in the shielding antenna for mobile phone on the body of cephalad direction, and is easy to use, and will have external antenna now and be positioned at a side position and change to and be positioned at the center.
The technical solution used in the present invention is: is that function absorbs the electromagnetic wave material by graphite powder and carbonyl iron dust by formula rate, fully mix with macromolecular material, the weight ratio of graphite powder and carbonyl iron dust is 9: 1, and graphite powder, carbonyl iron dust and macromolecular material weight ratio are 5: 5.Utilize the principle of power conversion, electro-magnetic wave absorption is converted to heat energy, be dispersed into the space, reach heat balance.
Embodiment
To have external antenna now is positioned at a side position and changes to and be positioned at the center, absorb, blocking-up electromagnetic wave composite material is to be functional material by graphite powder and carbonyl iron dust, cooperate macromolecular material silica gel, rubber, plastics, plastic cement, resin, lacquer mixes, the carbonyl iron dust of graphite powder and particle mean size≤3.5um fully mixes, weight ratio is 9: 1, graphite powder, carbonyl iron dust mixes and macromolecular material silica gel, rubber, plastics, plastic cement, resin, the abundant again mixed weight ratio of lacquer is 5: 5, make sheet, the paint shape, at built-in aerial in the cephalad direction casing, external antenna is renovated a side internal spray, paste and absorb, blocking-up electromagnetic wave composite material, thickness is 0.3mm-3mm.
This material shielding electromagnetic wave frequency band is 10MHz-5000MHz, and the shielding handset antenna radiation is to the electromagnetic wave attenuation 10dB-40dB of head direction.
Claims (3)
1, a kind of suction ripple environmental protection mobile phone will have external antenna now and be positioned at a side position and change to and be positioned at the center.
2, according to claim 1 described suction ripple environmental protection mobile phone, by graphite powder and carbonyl iron dust is functional material, cooperate macromolecular material silica gel, rubber, plastics, plastic cement, resin, lacquer mixes, the carbonyl iron dust of graphite powder and particle mean size≤3.5um fully mixes, weight ratio is 9: 1, graphite powder, carbonyl iron dust mixes and macromolecular material silica gel, rubber, plastics, plastic cement, resin, the abundant again mixed weight ratio of lacquer is 5: 5, make sheet, the paint shape, at built-in aerial in the cephalad direction casing, external antenna is renovated a side internal spray, paste and absorb, blocking-up electromagnetic wave composite material, thickness is 0.3mm-3mm.
3, according to claim 1 or 2 described suction ripple environmental protection mobile phones, renovate a side internal spray, paste absorption, block the electromagnetic wave composite material towards the inside and outside antenna of putting of cephalad direction casing at built-in aerial, the shielding handset antenna radiation is to the electromagnetic wave attenuation 10dB-40dB of head direction.
