The invention relates to a cable material, and specifically relates to a weatherable toughened modified
polyethylene cable sheath material. the material comprises the following raw materials in parts by weight: 15-19 parts of SG-2 PVC resin, 23-25 parts of POE, 24-28 parts of low-density
polyethylene, 14-18 parts of calcined potter's clay, 1-2 parts of
silver nitrate, 3-4 parts of
sodium chloride, 2-3 parts of
silane coupling agnet KH-550, 1-2 parts of
zirconium fluoride, 6-8 parts of nanometer
titanium dioxide, 2-3 parts of nanometer
titanium phosphate, 8-10 parts of dimethyl isooctyl thioglycolate
tin, 1-2 parts of anti-aging agent 4010, 12-15 parts of diatomite
powder, 2-3 parts of
ammonium polyphosphate, 25-30 parts of
tributyl citrate and 14-16 parts of an auxiliary agent. The insulating material combines the advantages of low-density
polyethylene, POE, PVC resin and the like, the
prepared material is good in rigidity, high in
toughness, good in mechanical properties, resistant to
environmental aging, resistant to heat, resistant to
flame, and safe and reliable to use, is widely applicable to preparation of various cable sheath insulating materials, and has wide market demanding prospect.
