Abstract
The utility model provides an aluminum-base compound shielding material. Polyethylene terephthalate (PET) is adopted as the base material of the shielding material. Aluminium foil is connected outside the single face or the double faces of the PET through glue, one layer or a plurality of layers of metal coating is arranged outside the aluminum foil, or the metal coating is arranged outside one face of the aluminum foil outside the double faces of the PET. Any one metal or several metals selected from copper, silver, nickel, gold, stainless steel and nickel-chromium alloy is/are adopted for the metal coating, and the thickness of each layer of the metal coating is 50-5000 angstroms. Holes are distributed on the shielding material with the double-face metal coating, the hole pitch is 0.1-8 mm, and the aperture is 0.03-3mm. The utility model is widely applied to products of computers, electron, communication devices and the like.
Description
Technical field:
The utility model relates to the electromagnetic shielding material that is used for electronics and communicator series products, relates in particular to aluminium base composite shielding material.
Background technology:
Along with development of electronic technology, electromagnetic radiation is more and more serious to the mankind's pollution, causes various electronics, communication apparatus dysfunction, and message is transmitted mistake and information unfavorable condition, and directly threatens human beings'health.For this reason, various countries have put into effect the minimum standard of a series of electronic product radiation in succession, allow the mankind reduced as much as possible by the chance of electromagnetic radiation pollution, also how to reduce the technology of electromagnetic radiation simultaneously in continuous research.Such as in electrical equipment, placing conductive fabric, the electromagnetic wave that produces when being used for shielding the circuit working in the electrical equipment on the one hand, can reduce simultaneously of the influence of external electromagnetic ripple to electrical equipment work itself, and the static derivation that electrical equipment can be produced, pre-anti-electricity device produces too much static.
At present, electromagnetic shielding material mainly contains two kinds: a kind of is to adopt conductive fabric to eliminate and weaken electromagnetic interference.This conductive fabric is to plate one deck nickel on mylar earlier, and then electro-coppering, and re-plating one deck nickel on the copper layer is oxidized to prevent copper at last, forms the layer of even conductive layer like this on cloth.This process using plating mode, and need three times (nickel-copper-nickel) of plating, can increase the complexity and the production cost of technology like this; Above-mentioned conductive fabric heat resistance is relatively poor simultaneously, can only be operated in the environment below 100 ℃, otherwise may cause burning, thereby jeopardize the operate as normal of electric equipment products.
Another kind of electromagnetic shielding material is to adopt clad aluminum foil.This material is base material with PET, is pasted with aluminium foil in the PET both sides.Because adopt aluminium foil as conductive layer, its cost is lower, and manufacture craft is also very simple.But because aluminium foil is not ferromagnetic material, so the effect of armoured magnetic field is little, and the easy oxidation of aluminium, corrosion stability difference and limited its application.
Summary of the invention:
The utility model purpose provide a kind of with low cost, electromagnetic shielding effect good, corrosion stability is strong, the aluminium base shielding material that can use under various complex conditions.
The utility model purpose can realize by following technical measures:
This shielding material is base material with PET, connects aluminium foil by glue outside the PET single or double, in the outside of aluminium foil the coat of metal is arranged, or outside one of them face of aluminium foil the coat of metal is arranged outside two-sided.
The utility model purpose also can realize by following technical measures:
The described coat of metal adopts any or several metals in the metals such as copper, silver, nickel, gold, stainless steel, nichrome; The coat of metal is one or more layers, and thickness is the 50-5000 dust; Cloth is porose on the shielding material of double-sided metal coating, and the pitch of holes in hole is 0.1-8mm, and the aperture is 0.03-3mm.
Two-sided the coat of metal arranged can realize double-side conduction by punching.
Can plate one or more layers metal level by methods such as vacuum magnetic-control sputtering, ion plating, evaporation, plating, metal level can adopt any or several in the metals such as copper, silver, nickel, gold, stainless steel, nichrome.
This electromagnetic shielding material can be directly adhesive in crested object (two-sided punching) as the form of conductive tape when using, also can combine with the foam of specific body becomes the form of conducting foam (single face does not punch), and is widely used in products such as computer, electronics, communication.
The utility model is with low cost, electromagnetic shielding effect good, have good function such as anti-oxidant, corrosion-resistant, can use under various complex conditions.
Description of drawings:
Fig. 1 is the electromagnetic shielding material schematic diagram that the two-sided subsides aluminium foil of the utility model embodiment does not punch;
Fig. 2 is that the single face of the utility model embodiment pastes the electromagnetic shielding material schematic diagram that aluminium foil does not punch;
Fig. 3 is the electromagnetic shielding material cutaway view of the two-sided subsides aluminium foil punching of the utility model embodiment.
