Abstract
The utility model provides a damp-proof sealed film, which mainly comprises a fibrous braiding base layer, a hot melt glue layer which covers the surface of the fibrous braiding base layer, and an aluminium foil layer covering the bottom surface of the fibrous braiding base layer, wherein a plastic layer can be also added between the fibrous braiding base layer and the aluminium foil layer. The utility model has the advantages of simple structure, high intensity, good softness, and good humidity resistance, can effectively prevent cable joints from wetting, is especially used for heat-shrinkable tubes in vertical package type, and is particularly suitable for the cable-splicing condition with strict damp-proof requirement.
Description
The utility model relates to a kind of cable splice parts, particularly relates to a kind of protection against the tide and seals film.
Existing longitudinally packed type heat shrinkable sleeve is to adopt metal clip pintle hook lock parcel cable splice, form tubular structure, in its suture site longitudinally, there is the hot melt adhesive of the overlap structure that is bonded to one with heat-shrinkable T bush to seal film, keep the resistance to air loss at cable splice place by it, the film that seals that generally adopts is coating one deck hot melt adhesive on plastic basis material, and intensity is relatively poor, influences resistance to air loss thereby easily wear out to crack or rupture.Chinese patent CN2209157Y discloses a kind of pyrocondensation and has assured and use the carrier type Hot melt adhesive tape, and it is being covered on the fiber flexible carrier by hot melt adhesive and is constituting, or by basic unit, is covering in the plastic layer on basic unit two sides and the hot melt adhesive layer that is covering on plastic layer to constitute.This kind structure has increased the intensity of Hot melt adhesive tape, when being applied to cable splice, can guarantee the requirement of structural strength, but structure is complicated, and moistureproofness is relatively poor, uses thereby limited on the strict moistureproof cable splice that requires.
It is a kind of simple in structure that the purpose of this utility model is to provide, and intensity height and moistureproofness are good, and film is sealed in the protection against the tide that is exclusively used in vertical packet mode heat-shrink tube.
The utility model protection against the tide is sealed film and is achieved in that it comprises fibrous braid basic unit, and is topped in the hot melt adhesive layer of fibrous braid substrate surface, topped aluminium foil layer in fibrous braid basic unit bottom surface.Wherein, the fibrous braid layer is by the radially silk of 0.1～0.5mm and the vertical mesh cloth that is interwoven, radially silk and vertical silk can be same material, as the polymer contractile filaments, or glass fibre, also can be differing materials, but radially to be polymer contractile filaments (as crosslinked high density polyethylene(HDPE) contractile filaments), vertically the mesh cloth that is interwoven for glass fibre is for well.The thickness of aluminium foil layer is advisable with 0.005～0.1mm.In order to increase the cohesiveness between fibrous braid basic unit and aluminium foil, but between increases one deck polyolefin layer.During use, the aluminium foil layer that contacts with cable one side can be coated with one deck hot melt adhesive again, also coated heat melten gel not, and the former contacts tightr with cable, and resistance to air loss is better.
The utility model protection against the tide seal film when using between longitudinally packed type heat shrinkable sleeve and cable, wherein, aluminium foil layer is affixed on cable surface, the hot melt adhesive face is affixed on the medial surface of longitudinally packed type heat shrinkable sleeve, and be in the longitudinal seam place of longitudinally packed type heat shrinkable sleeve, the seam crossing of heat-shrinkable T bush is clamped by pintle hook lock, and thermal contraction casing tube produces and shrinks after heating, and cable to be continued is tightly wrapped up.
The advantage that film is sealed in the utility model protection against the tide is simple in structure, the intensity height, and flexibility is good, can prevent effectively that cable from making moist, and resistance to air loss is good, is exclusively used in longitudinally packed type heat shrinkable sleeve.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
