Abstract
The invention relates to an anti-tracking polyethylene sheathing material which comprises a mixture of high-density polyethylene resin and low-density polyethylene resin, and an anti-tracking agent is filled in the blended and modified polyethylene resin. The anti-tracking polyethylene sheathing material has a favorable anti-tracking property and can eliminate the electrolytic corrosion phenomenon on the surface of an optical cable in a highfield and operate for a long time in a severe environment outdoors without faults.
Description
Technical field
The present invention relates to a kind of ADSS optical cable anti-electric-mark polyethylene sheath material, relate in particular to a kind of ADSS Polethylene protecting sheath material for optical cable with good anti-electric-mark effect.
Background technology
The optical cable sheath material that present domestic institute develops and produces is high density polyethylene(HDPE) sheath material, medium-density polyethylene sheath material and new LDPE (film grade) sheath material.As the high density polyethylene(HDPE) sheath material is to be base resin with the high density polyethylene(HDPE), adds modified resin again and makes through the parallel dual-screw extruding pelletization with other additive.The high density polyethylene(HDPE) sheath material has good heat-resistant aging, environmental stress crack resistance, also has very high tensile strength, elongation at break, is applicable to cable and cable sheath, and optical fiber is had enough provide protections.Machining process: all material is made through the parallel dual-screw extruding pelletization after the high-speed mixer high-speed mixing again.But on the optical cable in some particular surroundingss, it just can't reach the optical cable requirement as all dielectric self-supporting aerial optical cable.All dielectric self-supporting aerial optical cable (hereinafter to be referred as ADSS) is directly to lay on existing high-tension line, and circuit needn't have a power failure, and can lay the fiber number of big quantity simultaneously, and installation costs is cheap, but to optical cable, especially the electric erosion resistance of cable jacket has comparatively harsh requirement.The protecting sleeve of optical cable that domestic present institute develops and produces can't satisfy the requirement of its anti-electric trace.
Summary of the invention
In order to solve above-mentioned drawback, the invention provides a kind of anti-electric track resistant jacket material, it comprises base resin, anti-electric trace agent, oxidation inhibitor and lubricant, and wherein base resin is the mixture of high-density polyethylene resin and ldpe resin, and the weight percent of this sheath material is as follows:
High-density polyethylene resin: 44.2%～78.8%;
Ldpe resin: 9.2%～35.3%;
Anti-electric trace agent: 9.8%～25.0%;
Oxidation inhibitor: 0.8%～0.9%;
Lubricant: 1.1%～1.3%.
Wherein, described anti-electric track resistant jacket material is characterized in that described anti-electric trace agent is bismuth titanate or zirconium white or zinc oxide or aluminium sesquioxide or magnesium oxide or silicon powder or mica.
Wherein, described anti-electric track resistant jacket material is characterized in that oxidation inhibitor is antioxidant 1010, and lubricant is a polyethylene wax.
