Abstract
The utility model discloses a conductive foam with a wave absorption function. The conductive foam with a wave absorption function comprises a conductive foam body, a base cloth is coated on the external surface of the conductive foam body, the conductive foam body is bonded with the base cloth by a hot melt adhesive layer, a conductive coating is provided on the external surface of the base cloth, one side surface of the conductive coating is coated with a pressure sensitive adhesive layer, the surface of the pressure sensitive adhesive layer on the side opposite to the conductive coating is pasted by a release paper. According to the conductive foam with a wave absorption function, sealing and impact force alleviation effects are provided, electromagnetic wave spreading to the surface is conversed to heat or other forms of energy to be eliminated, thereby equipment safety is guaranteed, and electromagnetic threat in the environment is weakened.
Description
Technical field
The utility model relates to the electromangnetic spectrum field, relates in particular to a kind of conducting foam of inhaling wave energy that has.
Background technology
Along with the electronic product develop rapidly, also more and more harsher to its performance requirement, the foam product is widely used in electronic product, existing foam product is mainly that common PU foam, PUR are pasted together by mold heated, is to form with the release liners manufacturing again as base material is coated with solvent pressure-sensitive adhesive at its one or both sides take EVA or P E foam again.Effect with sealing, damping.
But this foam product only has the effect of sealing, damping, therefore, do not play the electromagnetic effect of eliminating, so the pollution to environment is not thoroughly eliminated, the electromagnetic wave that in electronic equipment, high-power components gives off, bring threat also for sensing unit in electronic product, the problems such as resonance occur.
Summary of the invention
The utility model provides a kind of conducting foam of inhaling wave energy that has, this conducting foam can play sealing, alleviate the effect while of impulsive force, also can its surperficial electromagnetic wave changes into heat energy or other energy eliminates with being diffused into, thereby brought safety guarantee to equipment, weakened the electromagnetism in the environment and threatened.
For achieving the above object, the technical solution adopted in the utility model is: a kind of conducting foam with suction wave energy, comprise the conducting foam body, this this external surface of conducting foam is coated with a base cloth, pass through the hot melt adhesive layer bonding connection between described conducting foam body and base cloth, described base cloth outer surface has a conductive coating, and this conductive coating one side surface is coated with pressure-sensitive adhesive layer, and a release liners is pasted on the opposing surface of this pressure-sensitive adhesive layer and conductive coating.
In technique scheme, further improved technical scheme is as follows:
In such scheme, the cross section of described conducting foam body is rectangle.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utlity model has the conducting foam of inhaling wave energy, comprise the conducting foam body, this this external surface of conducting foam is coated with a base cloth, pass through the hot melt adhesive layer bonding connection between described conducting foam body and base cloth, described base cloth outer surface has a conductive coating, this conductive coating one side surface is coated with pressure-sensitive adhesive layer, it plays sealing, alleviates the effect while of impulsive force, also can its surperficial electromagnetic wave changes into heat energy or other energy eliminates with being diffused into, thereby brought safety guarantee to equipment, weakened the electromagnetism in the environment and threatened.
Description of drawings
Accompanying drawing 1 is for the utlity model has the conductive foam structure schematic diagram of inhaling wave energy.
In above accompanying drawing: 1, conducting foam body; 2, base cloth; 3, hot melt adhesive layer; 4, conductive coating; 5, pressure-sensitive adhesive layer; 6, release liners.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: a kind of conducting foam with suction wave energy, comprise conducting foam body 1, this conducting foam body 1 outer surface is coated with a base cloth 2, pass through hot melt adhesive layer 3 bonding connections between described conducting foam body 1 and base cloth 2, described base cloth 2 outer surfaces have a conductive coating 4, these conductive coating 4 one side surfaces are coated with pressure-sensitive adhesive layer 5, and a release liners 6 is pasted on the opposing surface of this pressure-sensitive adhesive layer 5 and conductive coating 4.
The cross section of above-mentioned conducting foam body 1 is rectangle.
Adopt above-mentioned while having the conducting foam of inhaling wave energy, comprise the conducting foam body, this this external surface of conducting foam is coated with a base cloth, pass through the hot melt adhesive layer bonding connection between described conducting foam body and base cloth, described base cloth outer surface has a conductive coating, this conductive coating one side surface is coated with pressure-sensitive adhesive layer, it plays sealing, alleviates the effect while of impulsive force, also can its surperficial electromagnetic wave changes into heat energy or other energy eliminates with being diffused into, thereby brought safety guarantee to equipment, weakened the electromagnetism in the environment and threatened.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection range of the present utility model.
