Description
Technical field
The invention belongs to field of material engineering technology, be specifically related to a kind of magnetic plating Ag glass micro-
Pearl and preparation method thereof.
Background technology
In polymer base electro-magnetic screen composite material, for making composite have sufficiently high leading
Electricity rate reflects or electromagnetic wave absorption, it will usually doses in nonconducting polymeric matrix and has
The metal powder material of high conductivity, these metal powders are referred to as conducting filler.Work as conductive fill
When body doses certain mark (" diafiltration " threshold value), the specific insulation of composite can be dashed forward
The most acutely decline, " diafiltration " phenomenon occurs;Further, continue to increase when the filling fraction of electric conductor
Added-time, the specific insulation of composite quickly can tend towards stability, now the conduction of material internal
Path is the most perfect, is further added by conducting filler and also will not significantly improve the electric conductivity of material
Can, the deadweight of composite can be increased on the contrary and reduce its mechanical property.Therefore, reduction is compound
" diafiltration " threshold value of material is to improving the combination property of shielding composite and reducing cost
Highly beneficial.And reduce material " diafiltration " threshold value the best way and select conductance exactly very
High and that performance is sufficiently stable metal Ag powder.
In recent years, lightweight, green cheap to some, the material that is prone to processing carried out surface gold
Genusization replaces costliness and the excessive Ag powder of density, it has also become of conductive filler development
Important trend.Fact proved, plating Ag glass microballoon complies fully with as the substitute of pure Ag powder
Technology and the requirement in market.But, along with making rapid progress of science and technology, current electromagnetic shielding
The development of material fast forwards through to the requirement of more Gao Gengxin and target, wherein to " widescreen
Cover " the requirement most challenge of effect.This means to have improved merely the conductance of composite
Requirement can not be met, it is necessary to the function that another imparting composite is new while meeting high conductivity
Strengthen its shield effectiveness;And the introducing of magnetic material is by the electromagnetic shielding for improving composite
Performance injects new vitality.Because under the effect of electromagnetic wave, the magnetization of magnetic material presents dynamic
State process, the most not only also exists the magnetic hystersis loss not available for common dielectric, there is also
By energy loss produced by the effects such as magnetic aftereffect, domain wall resonance, natural resonance, and these are not
The electromagnetic wave of different frequency range it is respectively acting on again with the magnetic loss of mechanism.Such as, at 10kHz~
In the intermediate frequency range of 1MHz, magnetic material can occur dimensional resonance and magnetic force resonance phenomenon;?
In the high frequency stage of 1~100MHz, magnetic material will appear from domain wall resonance or relaxation;?
In 100MHz~10GHz uhf-range, magnetic material can occur natural resonance.Therefore, magnetic
The introducing of property material will strengthen the shield effectiveness of shielding material to a great extent and widens shielding
The shield ranges of material.
