Preparation of High Insulating HDPE Optical Cable Sheath at Lower Cost with Doping Nano-Particles

Abstract:

To reduce the cost of HDPE optical cable sheath, we selected HDPE as matrix materials, inorganic nanometer particles (CaCO₃, SiO₂) as modifier, prepared the modified HDPE optical cable sheath by mechanical blending method. The combination of CaCO₃ particles with HDPE matrix was improved by titanate doped, which was able to facilitate the homogeneous dispersion of CaCO₃ particles inside HDPE. To modify the optical cable sheath and reduce the product cost, the disparity of the inorganic nano-particle was analyzed, and the ratio of raw material and mixing technology were also improved. The experimental results indicated that: the sheathing compound with insulating characteristic as well as all technical indexes that reached its national standard, especially the toughening effect of the CaCO₃, could be produced when CaCO₃ content reached 7.5% and the volume resistivity was 10⁴ times higher than the national standard. The mechanical modification of CaCO₃ was better than SiO₂.
