Description
Technical field
The utility model is related to electronic shield technical field, specially a kind of chemical bridge formation conducting foam.
Background technology
Conducting foam is that one kind wraps up conductive fabric on flame-retardant sponge, after a series of processing, is made it have good
Surface conductivity, performance and electrostatic protection performance with electromagnetic shielding, can in conducting foam built in electronic product,
On the one hand it is used for shielding the electromagnetic wave produced during electron product circuit work, on the other hand can reduces external electromagnetic ripple to electronics
The influence of product, the electrostatic that electronic product is produced in itself outwardly exports prevention and produces excessive electrostatic, and material is lighter,
And to ambient humidity no dependence, therefore it is widely used in electronics field, in addition it is all extensive in military project and space industry
Using.
Now widely used conducting foam, used material is usually polyurethane foam material, and is wrapped up above
Conductive fabric, but be due to that processing technology can cause its conductive fabric and internal foam Nian Jie not tight, gap is easily produced, influence is overall
Shield effectiveness；Secondly, conventional cross-section is typically designed to rectangle, and its edges and corners is relatively fragile, is easily rolled over when transporting or using
Damage, conductive fabric crack is occurred；Finally, conventional conductive foam is easily extruded between being positioned over electronic device by electronic device,
Make the change of conducting foam generation in shape, be unfavorable for the fixation of conducting foam.
Utility model content
To achieve the above object, the utility model provides following technical scheme：A kind of chemical bridge formation conducting foam, including it is interior
Core, the inner core outer layer scribbles one layer of adhesive layer, and the adhesive layer outer layer is surrounded by conductive fabric, and the conductive fabric four sides posts double
Face viscose glue.
As a kind of preferred technical scheme of the utility model, the inner core is a kind of chemical bridge formation cotton, and specific material is
Processes for chemically crosslinked polyethylene foamed cotton, the conductive fabric is cupro-nickel conductive fabric.
As a kind of preferred technical scheme of the utility model, the interior core section is round rectangle, and corner is arc.
As a kind of preferred technical scheme of the utility model, sticked on the inside of the tacky on two sides on conductive fabric, outer layer is attached
There is one layer of plaster paper.
Compared with prior art, the beneficial effects of the utility model are：The chemical bridge formation conducting foam, it is poly- with chemical crosslinking
Ethene foamed cotton instead of traditional polyurethane foam material, and with higher expansion ratio, higher is elastic and higher
Toughness, and be easily recycled relative to polyurethane, pollution is not resulted in, it is more environmentally-friendly；Secondly, conductive fabric is enable by adhesive layer
It is enough more to add closely patch and inner core material, and keep the deformation synchronous with inner core, it is ensured that overall shield effectiveness；Secondly
By the way that inner core is set into round rectangle, it is arcuate structure to make original arm of angle of rectangle four, allows the power suffered by corner angle can be by arc knot
Structure disperses, and makes it be difficult to lose, transporting and using also will more facilitate；Secondly, tacky on two sides is set outside conductive fabric,
The stability of conducting foam when in use is improved, it is fixed on electronics production by viscose glue when being extruded by device
On product.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Embodiment：
Fig. 1 and Fig. 2 are referred to, the utility model provides a kind of technical scheme：A kind of chemical bridge formation conducting foam, including it is interior
Core 1, the outer layer of inner core 1 scribbles one layer of adhesive layer 2, and the adhesive layer outer layer is surrounded by conductive fabric 3, and the four sides of conductive fabric 3 is
Post tacky on two sides 4.
Preferably, the inner core 1 is a kind of chemical bridge formation cotton, and specific material is processes for chemically crosslinked polyethylene foamed cotton, institute
Conductive fabric 3 is stated for cupro-nickel conductive fabric, traditional polyurethane foam material is instead of with processes for chemically crosslinked polyethylene foamed cotton, with more
High expansion ratio, higher elastic and higher toughness, and be easily recycled relative to polyurethane, pollution is not resulted in,
It is more environmentally-friendly, using cupro-nickel conductive fabric, optimal electric conductivity and shielding properties can be reached；The section of inner core 1 is fillet square
Shape, corner is arc, and the power suffered by corner angle can be disperseed by arcuate structure, makes it be difficult to lose, and transports and uses
Will more it facilitate；The inner side of tacky on two sides 4 is sticked on conductive fabric 3, and outer layer is with one layer of plaster paper 5, for protecting viscose glue,
Tear when in use.
Other, the processes for chemically crosslinked polyethylene foamed cotton that the utility model is used is one kind ldpe resin
Plus chemical cross-linking agent and foaming agent are formed by high temperature is continuous foamed, are a kind of Novel environment-friendlymaterial material, nontoxic, tasteless, sound insulation, suction
Sound, it is heat-insulated, burn when it is pollution-free to air, screen resilience is good, can arbitrarily adjust soft durometer and thickness, is it the features such as lightweight
His cotton-like material that foams is irreplaceable, and it has expansion ratio high compared with similar products, and density is low, thickness of thin, table
Face is smooth, high resiliency, high tenacity, it is easy to secondary workability.
Specifically used mode and advantage：The chemical bridge formation conducting foam, biography is instead of with processes for chemically crosslinked polyethylene foamed cotton
The polyurethane foam material of system, with higher expansion ratio, higher elastic and higher toughness, and relative to poly- ammonia
Ester is easily recycled, and does not result in pollution, more environmentally-friendly；Secondly, by adhesive layer enable conductive fabric can more add closely patch and
Inner core material, and keep the deformation synchronous with inner core, it is ensured that overall shield effectiveness；Circle is set to secondly by by inner core
Angular moment shape, it is arcuate structure to make original arm of angle of rectangle four, and the power suffered by corner angle can be disperseed by arcuate structure, makes it not easy to break
Damage, transporting and using also will more facilitate；Secondly, tacky on two sides is set outside conductive fabric, conducting foam is improved and exists
Stability when using, makes it to be fixed on when being extruded by device by viscose glue on electronic product.
