The electromagnetic wave shielding material is characterized in that the electromagnetic wave shielding material also comprises insulating cloth, a release material layer and two adhesive layers. The electromagnetic wave shielding material is sequentially composed of the release material layer, a first adhesive layer, conductive cloth, a second adhesive layer and insulating cloth from the inner part to the outer part. The two adhesive layers bond the release material layer, the conductive cloth and the insulating cloth. The external surface of insulating cloth can be coated or printed with colors or patterns. The insulating requirement is satisfied when the recognizing requirement or decorating requirement is satisfied. The electromagnetic wave shielding material provided by the invention has the advantages of single-surface or double-surface insulation, easy insurance of assembling precision and easy use.
Description
Technical field
The present invention relates to a kind of electromagnetic shielding material that is applicable to electronic products such as computer, electronic game skill machine, mobile phone.
Background technology
Electronic products such as computer, electronic game skill machine, mobile phone have spread in the general family life.These products along with industrial use to general purpose expansion, the electromagnetic wave of its leakage usually causes the maloperation to other electronic product or equipment, or causes problem such as communication apparatus electromagnetic wave obstacle, and is even more serious, electromagnetic wave can produce harm to health.
For addressing the above problem, industrial common use metallic shield net, yet the cost height of wire netting, physical property is undesirable again.Invented metal cladding on the nonmetallic materials afterwards again, to solve the electromagnetic wave shielding problem, the method for preparing silver metallized of people such as Xia Zhilin, summer dragon's fountain disclosed a kind of organic fiber and fabric in Chinese invention patent document CN1687507A for example is according to i.e. genus the said goods of this method preparation.
Yet the said goods is single metal color, can't satisfy the instructions for use of user to color, and inconvenient identification to different parameters material itself.When insulating requirements being arranged, when being the assembling electronic product, the practice commonly used adds one deck felt pad, though this practice can play insulation effect at the interior of gauze screen or (reaching) outside for single or double, but for complicated shape, production technology is cumbersome, and is difficult for guaranteeing precision, uses inconvenient.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part and provide the insulation of a kind of single or double tool, guarantee assembly precision, electromagnetic shielding material easy to use easily.
Purpose of the present invention can be achieved through the following technical solutions:

Electromagnetic shielding material is characterized in that: described first adhesive layer is a conduction hot melt adhesive material, and described second adhesive layer also is a conduction hot melt adhesive material, the electromagnetic shielding material single face insulation of composition, and conduct electricity the bottom surface, to satisfy the instructions for use of single face insulation.Certainly, first adhesive layer also can adopt insulation hot melt adhesive or insulation pressure sensitive adhesive, and only second adhesive layer adopts the conduction hot melt adhesive, also can satisfy the instructions for use of single face insulation.
Electromagnetic shielding material is characterized in that: described empire cloth is an acetic acid cloth.
Electromagnetic shielding material is characterized in that: described electromagnetic shielding material is a roll material.Adopt convenient storage of rolling mode and transportation, also be convenient to working continuously of back operation (stamp).
Electromagnetic shielding material involved in the present invention comprises conductive fabric, it is characterized in that: also comprise empire cloth, separated type material layer, two adhesive layers; Described electromagnetic shielding material is separated type material layer, first adhesive layer, conductive fabric, second adhesive layer, empire cloth from inside to outside successively; Two adhesive layers are bonded as one separated type material layer, conductive fabric, empire cloth.The outside of empire cloth can coating or print color or pattern, to satisfy identification requirement or to decorate requirement.When wherein first adhesive layer is insulating materials, constitute double-sided insulation, when first adhesive layer is conductive material, constitute the single face insulation, to satisfy different instructions for uses.The electromagnetic shielding material that the present invention relates to, collection empire cloth, two adhesive layers, conductive fabric, release layers are one, compare with prior art, can directly use behind stamp, need not to increase excess material or insulating materials again in stamp operation or assembly process, easy to use.And, the insulating materials of electromagnetic shielding material of the present invention and conductive fabric are in integral type, can guarantee the shape unanimity of the two during stamp, and the two integrated packing into (subsides are gone into) electronic product, and prior art is post forming, so the secondary assembling is the easier assurance assembly precision of electromagnetic shielding material of the present invention.
Description of drawings
Fig. 1 is the schematic cross-section of first embodiment of the invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to figure 1, first embodiment of the present invention is a kind of electromagnetic shielding material of double-sided insulation, comprises conductive fabric 103, also comprises empire cloth 101, separated type material layer 105, two adhesive layers 102 and 104; Described electromagnetic shielding material is separated type material layer 105, first adhesive layer 104, conductive fabric 103, second adhesive layer 102, empire cloth 101 from inside to outside successively; Two adhesive layers 102 and 104 are bonded as one separated type material layer 105, conductive fabric 103, empire cloth 101.In the present embodiment, the outside coating of empire cloth 101 is black, described first adhesive layer 104 is by the insulation pressure-sensitive adhesive material, described second adhesive layer 102 also is the insulation pressure-sensitive adhesive material, described separated type material layer 105 is release liners, described conductive fabric 103 is made of the silvering on nonwoven and surface thereof, and described empire cloth 101 is an acetic acid cloth.Described electromagnetic shielding material employing rolling mode is stored and is transported, and also is convenient to working continuously of back operation (stamp).The electromagnetic shielding material of present embodiment, collection empire cloth 101, two adhesive layers 102 and 104, conductive fabric 103, release layers 105 are one, compare with prior art, can behind stamp, directly use, need not to increase excess material or insulating materials again in stamp operation or assembly process, easy to use.And, the empire cloth 101 of electromagnetic shielding material of the present invention and conductive fabric 103 are in integral type, can guarantee the shape unanimity of the two during stamp, and the two integrated packing into (subsides are gone into) terminal electronic product, need not the assembling of post forming and secondary, so the electromagnetic shielding material of present embodiment is easy to guarantee assembly precision.
