Description
Technical field
The present invention relates to Study on Foamed Aluminum Technology field, and in particular to a kind of foamed aluminium material of high energy absorption ability.
Background technology
Modern high technology is continued to develop so that electromagnetic interference caused by electromagnetic wave and electromagnetic compatibility problem be increasingly tight
Weight, not only interferes and damages to electronic instrument, equipment, influence its normal work, serious to restrict China's electronic product and set
Standby international competitiveness, and pollute the environment, endanger human health；Other electromagnetic wave leakage also pacify by entail dangers to national information
The safety of complete and military vital strategic secrets.Substantial dash forward is had been achieved with especially as the electromagnetic pulse weapon of new concept weapon
It is broken, electronic equipment, power system etc. can directly be hit, cause the temporary transient failure of information system etc. or permanent damage
Bad and powerful electromagnetic pulse can also be damaged to human body, make one neurological disorders, behavior out of control etc..Therefore, we will and
When take electromagnetic protection measure, prevent the generation of electromagnetic interference and electromagnetic compatibility problem.
Foamed aluminium material is a kind of novel environment friendly electromagnetic shielding material risen in the last few years, and it has special cellular
Structure, is a kind of density ratio water also small metal material, with good resistance to compression and impact strength, and shield effectiveness is high,
The shielding needs of preferable sensitive instrument and equipment can be met, secret leakage are prevented, reduction is to the injury of human body and to other electricity
The interference of sub- instrument.In addition, because its have recyclable, environmentally friendly concurrently the characteristics of, adapted to the development of current social, more at home and abroad
Industrial circle and high-tech sector are widely applied.
Direction of the absorbing material towards " thin, light, wide, strong " is developed, and research shows, fine and close absorbing material is through porous
Its absorbing property is significantly improved after change, at the same can lightening material significantly density.However, at present to porous absorbing material
Research report it is more rare, the analysis of its wave-absorbing mechanism is also at the elementary step.Porous foam metal material is a kind of new
Porous light metal material, the performance such as people's system research its damping, shock resistance, sound absorption damping, electromagnetic wave shielding,
Also few people are studied its absorbing property.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of composition simply, the good aluminium for being used to be electromagnetically shielded of effect
Base compound binding agent.
