Abstract
The utility model provides a multi-layer composite conductive hot contracting pipe which is divided into at least two layers; wherein, at least one layer macromolecule material conductive layer and at least one insulation layer are alternatively composite. A layer of internal adhibit layer can be compounded on the internal layer according to the requirement. Without the longitudinal joint seam, the utility model can be radially contracted and densely wrapped. As good shielding performance, the utility model can be conveniently applied to the positions where the high shielding exists and the metal material can not be used. The utility model can be applied to the fields of electrons, electrical apparatuses, special electronic signal technology, etc.
Description
Technical field
The utility model relates to a kind of heat-shrinkable tube, particularly relates to a kind of MULTILAYER COMPOSITE conduction heat-shrinkable tube.
Background technique
Heat-shrinkable tube is widely used in every field such as power cable, communication cable and optical cable, petroleum and natural gas pipeline, its main performance is the back generation contraction of being heated, and cable, optical cable or pipeline are closely wrapped up, and is used for its field boundary that continues and closes, but do not have conducting function, can not be used for special field boundary and close.Chinese patent CN2217714Y has introduced a kind of tinsel and has strengthened the shield type sealing thermal contraction casing tube that continues, it by the metal lamella as sandwich layer, with the polyolefin plastics compound molding be whole, after pressing even, fixes by press with metal clip, and paste one deck gluing composition metal plastic layer increasing, so that the usefulness of replenishing compound material during heat shrink by flanging mouth place.It is a kind of heat-shrinkable tube that the sheet material cladding is formed with metal clip, promptly exists one to connect seam longitudinally, has the electromagnetic effect of shielding.
Technology contents
It is a kind of easy to process that the purpose of this utility model is to provide, and do not have the seam of connection overall structure, and have the MULTILAYER COMPOSITE conduction heat-shrinkable tube of electric conductivity and radially thermal shrinkage.
The utility model MULTILAYER COMPOSITE conduction heat-shrinkable tube is not for there being the multilayer overall structure that vertically connects seam, at least two-layer, i.e. one deck conductive layer and at least one layer insulating at least, for two-layer when above, conductive layer and isolation layer are for alternately compound, internal layer and skin can be conductive layer, also can be isolation layer, are generally 5 layers of structure of 2～｀.Conductive layer is generally macromolecule conducting material, and its specific volume resistance is less than 10
-1Ohmcm.Isolation layer is generally polyolefine material, or adds reinforcing material, as the polyolefin compound body of reinforcing fiber, also can be other crosslinkable macromolecular material, and isolation layer resistance is greater than 10
12Ohmcm.Also can at the compound one deck adhesive layer of internal layer, be generally the viscosity macromolecular material as required,, be formed with the interior viscous heat collapsible tube of conductive layer, strengthen sealability as hot melt adhesive etc.
The advantage of the utility model MULTILAYER COMPOSITE conduction heat-shrinkable tube is, it is the no longitudinal seam overall structure that becomes through RADIATION PROCESSING again by after the MULTILAYER COMPOSITE, because conductive layer and isolation layer all have radially thermal contraction performance, make the bigger heat shrink function of its whole realization, parcel is closely.Has good electrical properties, be widely used in the electromagnetic shielding field, also can be by any variation between conductive layer and the isolation layer, to adapt to different specific (special) requirements, or play the effect of similar switch body by special device, because shielding is good, needing can be advantageously used in the high place that shields and can not use metallic material
