Description
Technical field
The present invention relates to new material technology field, more particularly to a kind of FeNiCo polyaniline wave absorbing materials.
Background technology
With the development of modern science and technology, impact of the electromagenetic wave radiation to environment increasingly increases.Airport, machine flight because
Electromagnetic Interference cannot be taken off and overdue；The normal work of various electronic instrument for diagnosing and curing diseases devices can often be disturbed in hospital, mobile phone.Cause
This, administers electromagnetic pollution, finds a kind of material that can be kept out and weaken electromagenetic wave radiation --- absorbing material, it has also become material supply section
The big problem learned.
Absorbing material refer to can absorb, decaying projects the electromagnetic wave energy of material surface, and by electromagnetic energy by material
The dielectric loss in portion is converted into into the class functional material that the energy dissipation of the other forms such as heat energy is fallen.Absorbing material is by absorbing
Agent, adhesive and various auxiliary agents composition, the electromagnetic performance of wherein absorbent determines the quality of microwave absorbing coating performance, in cell material
Misusing for key is played in material.
Research confirms that ferrite wave-absorbing material performance is optimal, and it has, and absorption frequency range is high, absorbance is high, matching thickness is thin
The features such as.This materials application is can absorb in electronic equipment the electromagnetic radiation of leakage, the mesh for eliminating electromagnetic interference can be reached
's.According to the rule that electromagnetic wave is propagated from the high magnetic conductance direction of low magnetic steering in media as well, using high magnetic conductivity ferrite guiding electricity
Magnetic wave, by resonance, the emittance of a large amount of electromagnetic wave absorptions, then by coupling the energy conversion of electromagnetic wave into heat energy.
With the development of modern crafts, the requirement more and more higher to absorbing material, it is desirable to while wave-absorbing effect is preferable,
Possess preferable physical and mechanical propertiess, preferable heat-resisting quantity and working service simple etc..
The content of the invention
It is an object of the invention to propose a kind of FeNiCo polyaniline wave absorbing materials, the absorbing property for enabling to material is big
Width is lifted.
A kind of earlier patent application " FeNiCo absorbing materials " of inventor is carried out to the suction ripple material in impedance matching layer
Optimization, but for other compositions are improved.To cause the overall performance of absorbing material more excellent, the present invention is to the suction ripple
The other compositions and composition of material are improved, and to be matched with the FeNiCo, reach the optimization of performance.
It is that, up to this purpose, the present invention is employed the following technical solutions：
A kind of FeNiCo polyaniline wave absorbing materials, which is made up of impedance matching layer, depletion layer and reflecting layer from top to bottom, resistance
Fe of the anti-matching layer by 2-8wt%0.5Ni0.4Co0.1Powder body is formed in being distributed to polyaniline, and depletion layer is distributed to for hydroxy iron powder
Formed in neoprene, reflecting layer is formed in neoprene by graphite dispersion.
By each magnetic micro-powder of comparison 0.5～6.0GHz low-frequency bands electromagnetic parameter situation of change, find Fe,
The magnetic loss performance of the Bimary and trinary alloy of Co.Ni is excellent more than Fe, Co, Ni unitary metal fine powder.NiCo and FeCo, be
The combination of magnetic loss better performances in binary alloy, they have excellent electromagnetic property, and phase structure is respectively solid solution, with
And Taenite systems.The Fe of the present invention0.5Ni0.4Co0.1Ternary alloy three-partalloy, phase structure are similarly Taenite systems (Fe, Ni), but lattice
Middle solid solution has entered Co, its μ " the maximum relative value in 0.5-6.0GHz has 1.9, and frequency range of the numerical value more than 1.4 is 4GHz.
Therefore, FeNiCo ternary alloy three-partalloys can be obtained than Fe, the electromagnetic performance that Ni.Co binary or unitary will be good.
The present invention is combined by specific recipe ingredient, devise impedance matching layer/depletion layer/reflecting layer composition three layers
Thin film, its positive wave-absorbing effect are significantly better than reverse side, the front membrane structure design it is correct.Suction of the present invention
Wave material,, when thickness is 0.2mm, its absorption maximum exceedes -34dB, excellent performance for which.
