Abstract

The invention relates to the technical field of cables, and specifically discloses an antistatic polyolefin cable material, a cable sheath and a manufacturing method thereof. The above-mentioned antistatic polyolefin cable material is made of the following raw materials in parts by weight: 50-65 parts of the inner layer cable material, 5-8 parts of the first interlayer cable material, 30-40 parts of the heat-conducting middle layer cable material, and 30-40 parts of the second interlayer cable material. 5-8 parts of cable material and 15-20 parts of surface layer cable material; surface layer cable material is KPH-0805 cable material; heat-conducting middle layer cable material is doped polyacetylene particles; inner layer cable material, first interlayer cable The material, the heat-conducting middle layer cable material, the second interlayer cable material and the surface layer cable material are arranged in an overlapping manner in the direction close to the cable line, and the adjacent two layers are bonded and fixed. The outer sheath of the cable is sequentially adhered with an inner layer, a first interlayer, a heat-conducting middle layer, a second interlayer and a surface layer from a direction close to the conductor core. The cable sheath has the advantages of resistance to environmental stress cracking, high efficiency and long-lasting antistatic.

Description

Technical field [0001] The present invention relates to the field of cable technology, more particularly, it relates to an antistatic polyolefin cable material, cable wire skin and a method of making it. Background [0002] The cable is made from the inside to the outside by the conductor core, the insulating sheath and the cable wire skin; the above edge sheath and the cable wire skin are successively wrapped on the outside of the conductor core. Due to the abundant raw materials, low price, easy processing and molding, and excellent comprehensive performance, polyolefins have become a type of polymer material with the largest output and wide application. However, polyolefins have strong electrical insulation, and at present, the addition of antistatic agents is the most commonly used method to eliminate polyolefin static electricity. The so-called antistatic agent refers to an additive that is applied to the surface of a material or blended inside a material to reduce the accum...
