Problems solved by technology

In addition, the disadvantage of polyethylene and polyvinyl chloride is that they are not fire-resistant, and the working temperature is 70~90°C, especially polyvinyl chloride and chlorine, which are harmful to human body and environmental protection, and will produce toxic gas when burned. Strict requirements: are gradually being phased out

Abstract

The invention discloses a polypropylene cable material. The polypropylene cable material is prepared by the following raw materials in parts by weight: 40 to 57 parts of metallocene linear polyethylene, 25 to 30 parts of atactic polypropylene, 3 to 4 parts of red phosphorus, 8 to 10 parts of magnesium hydroxide, 7 to 9 parts of gas-phase white carbon black, 50 to 57 parts of a composite filler, 2 to 4 parts of nano-calcium carbonate, 0.4 to 0.6 part of capsaicine, 3 to 6 parts of cashew nut shell oil, 5 to 8 parts of isophthalic acid ester, 1 to 2 parts of glycerol triacetate, 0.5 to 1 part of dioctyl maleate, 1 to 2 parts of ferrocene, and 1 to 3 parts of a colored glaze mixed material coloring agent. In addition, the invention also discloses a preparation method for the polypropylene cable material; the polypropylene cable material obtained by the preparation method has the advantages of high mechanical and machining properties, high temperature resistance grade, high impact resistance, high mechanical properties, high resistance to corrosion of a plurality of organic solvents, acids and alkalis, high cracking resistance and the like, is suitable for a cable, and can better protect the cable.

Description

[0001] technical field [0002] The invention relates to the field of cable materials, in particular to a polypropylene cable material and a preparation method thereof. Background technique [0003] Special resins for wire and cable include cable insulation materials and cable sheath materials, and the raw materials used are mainly polyethylene and polyvinyl chloride. At present, domestic power cables above 6kV have all used polyethylene cross-linked insulating materials; low-voltage cables below 1 kV are mainly made of polyvinyl chloride insulation and polyvinyl chloride sheath, but due to the stability and electrical insulation of polyvinyl chloride Poor, therefore, it is being replaced by polyethylene more and more; communication cables generally use high-density polyethylene as the insulating layer, and linear low-density polyethylene as the sheath layer; optical cables are mainly made of high-density polyethylene and medium Density polyethylene is used as sheathing mat...
