By selecting specific compositions from FeNiCo alloy powder to cooperate with the specific impedance matching layer base material, an unexpected technical effect is achieved.
Description
Technical field
The present invention relates to new material technology field, more particularly, to a kind of FeNiCo polypyrrole absorbing material.
Background technology
With the development of modern science and technology, the impact to environment for the electromagenetic wave radiation 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 often can be disturbed in hospital, mobile phone.Cause
This, administer electromagnetic pollution, finds a kind of material absorbing material that can keep out and weaken electromagenetic wave radiation, it has also become material supply section
The big problem learned.
Absorbing material refers to absorb, decaying projects the electromagnetic wave energy of material surface, and electromagnetic energy is passed through in 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 agent composition, the electromagnetic performance of wherein absorbent determines the quality of microwave absorbing coating performance, in cell material
Misusing of key is played in material.
Research confirms, ferrite wave-absorbing material performance is optimal, and it has, and absorption frequency range is high, absorptivity is high, matching thickness is thin
The features such as.By this materials application, the absorbable electromagnetic radiation revealed in electronic equipment, can reach the mesh eliminating electromagnetic interference
's.The rule propagated from low magnetic steering high magnetic conductance direction in media as well according to electromagnetic wave, guides electricity using high magnetic conductivity ferrite
Magnetic wave, by resonance, the emittance of a large amount of electromagnetic wave absorptions, then becomes heat energy by coupling the energy conversion of electromagnetic wave.
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 properties, preferable heat-resisting quantity and working service simple etc..
Content of the invention
It is an object of the invention to proposing a kind of FeNiCo polypyrrole absorbing material, the absorbing property enabling to material is big
Width is lifted.
A kind of earlier patent application " FeNiCo absorbing material " of inventor is carried out to the suction ripple material in impedance matching layer
Optimize, but other compositions are improved.Overall performance for making absorbing material is more excellent, and the present invention is to described suction ripple
The other compositions of material and composition are improved, and to be mated with described FeNiCo, reach the optimization of performance.
For reaching this purpose, the present invention employs the following technical solutions：
A kind of FeNiCo polypyrrole absorbing material, it is made up of impedance matching layer, depletion layer and reflecting layer from top to bottom, resistance
Anti- matching layer is by the Fe of 2-8wt%0.5Ni0.4Co0.1Powder is distributed in polypyrrole and is formed, and depletion layer is distributed to for hydroxy iron powder
Formed in neoprene, reflecting layer is formed in neoprene by graphite dispersion.
By relatively each magnetic micro-powder 0.5～6.0GHz low-frequency band 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 system.The Fe of the present invention0.5Ni0.4Co0.1Ternary alloy three-partalloy, phase structure is similarly Taenite system (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 more than 1.4 for the numerical value is 4GHz.
Therefore, FeNiCo ternary alloy three-partalloy can obtain ratio Fe, the electromagnetic performance that Ni.Co binary or unitary will be good.
The present invention passes through specific recipe ingredient, and three layers that devise impedance matching layer/depletion layer/reflecting layer composition are combined
Film, the wave-absorbing effect in its front is significantly better than reverse side, front described membrane structure design correct.Suction of the present invention
Wave material,, when thickness is for 0.2mm, its absorption maximum exceedes -34dB, excellent performance for it.
