Abstract

The invention discloses a black weather-stress-cracking-resistant polyethylene cable sheath material and a preparation method thereof. The black weather-stress-cracking-resistant polyethylene cable sheath material is prepared from the following raw materials in parts by weight: 55-75 parts of linear low-density polyethylene , 20-30 parts of high-density polyethylene, 15-20 parts of EVA resin, 10-15 parts of diisononyl phthalate, 8-12 parts of propanediol sebacate polyester, 5-10 parts of epoxidized linseed oil, 10-15 parts of antimony trioxide, 5-10 parts of zinc stannate, 5-10 parts of ,nanometer zeolite powder, 3-5 parts of straw ash, 4-6 parts of a composite filling material, 8-12 parts of nanometer dolomite, 20-30 parts of channel black, 2-3 parts of dibutyltin dilaurate, 1-2 parts of calcium stearate, 1-2 parts of zine stearate, 3-5 parts of oxidized polyethylene wax, 0.5-1 part of antioxidant DLTP and 1-2 parts of antioxidant 1010. The cable material of the invention has excellent performances comprising environment stress cracking resistance, high temperature resistance, oil resistance, cold resistance, acid-base resistance, weathering aging resistance, wear resistance and the like, has good running in a working environment of -40 DEG C to 95 DEG C without deformation and cracking, and is safe, reliable and durable in use.

Description

technical field [0001] The invention relates to a black environmental cracking-resistant polyethylene cable sheath material and a preparation method thereof, belonging to the technical field of cable materials. Background technique [0002] Black polyethylene cable material is made of low-density polyethylene resin, carbon black and other additives, melted and kneaded, and granulated. As a cable sheath material, it not only has excellent dielectric properties, but also has excellent physical and mechanical properties. It is suitable for sheath materials of communication, control, signal and electric cables, and can be laid overhead, buried or underground. However, the existing polyethylene sheath material is easily deformed when subjected to external force or molding process during use, and is easy to crack when contacted with liquid solvent and its vapor state, which limits its application range. Contents of the invention [0003] The object of the present invention is t...
