Abstract
The invention relates to a photo-electricity tube forming filling component with core line that includes core line and forming layer. The core line is made up from warp yarn, and the foaming layer is made up of 98-99% high density polyethylene basic resin, and 1-2% nucleation agent. The invention could ensure the rounding of the tube, and saves raw material, and improves the intention.
Description
Technical field
The present invention relates to a kind of filling member in the optical cable, especially foam filled.
Background technology
The optical cable filling member is that the room of filling up in the stranded process of cable core in the cable core makes it keep a kind of element of rounding, existing optical cable is generally the solid filling member that adopts the high density Insulation Material to extrude with filling member, because hardness is higher, easily make the cable core distortion when filling member and other element twist altogether in the stranded process of cable core, influence the roundness of optical cable.
Summary of the invention
In order to overcome the deficiency that existing optical cable filling member exists, the invention provides a kind of filling member of outsourcing foaming layer of belt carcass line, be used in the optical cable when twisting altogether and easily make cable core keep rounding with other element, can not influence the roundness of optical cable.
The foamable filling up piece in use for optical cable of a kind of belt carcass line provided by the invention has heart yearn (1), outside heart yearn (1), be surrounded by foaming layer (2), heart yearn (1) adopts the glass yarn to make, and foaming layer (2) is that to mix back fusion refining be that one coats outside heart yearn (1) and forms for base-material, the nucleator that adds 1-2% with the high density polyethylene base resin of 98-99%.
Consisting of of the nucleator that the present invention adopts: 5% modification azo virtue diamides and 95% low density polyethylene.
The invention has the beneficial effects as follows: owing to establish heart yearn (1), outsourcing foaming layer (2) in the filling member, foam degrees reaches 60-70%, and the surface is softer, easily makes cable core keep rounding when twisting altogether with other element, thereby also guaranteed the roundness of optical cable, and saved material, reduce production costs; With the heart yearn (1) of glass yarn, improved the intensity of optical cable as filling member.
Description of drawings
Fig. 1 is a cross sectional representation of the present invention.
In Fig. 1,1. heart yearn, 2. foaming layer.
Embodiment
The invention will be further described below in conjunction with embodiment, with reference to Fig. 1.
Embodiment 1. is a base-material with 98% high density polyethylene base resin, the nucleator of interpolation 2% mixes back fusion refining and is one, makes heart yearn (1) high speed under 165-185 ℃ of temperature with the glass yarn and extrudes, and forms foaming layer (2), foam degrees is 60-70%, promptly makes the present invention.
Embodiment 2. is a base-material with 99% high density polyethylene base resin, the nucleator of interpolation 1% mixes back fusion refining and is one, makes heart yearn (1) high speed under 165-185 ℃ of temperature with the glass yarn and extrudes, and forms foaming layer (2), foam degrees is 60-70%, promptly makes the present invention.
Claims (1)
1, a kind of foamable filling up piece in use for optical cable of belt carcass line, it is characterized in that having heart yearn, outside heart yearn, be surrounded by foaming layer, heart yearn adopts the glass yarn to make, and foaming layer is that to mix back fusion refining be that one coats outside heart yearn and forms for base-material, the nucleator that adds 1-2% with the high density polyethylene base resin of 98-99%.
