Abstract

The invention provides a high-toughness and halogen-free flame retardant polypropylene cable material. The high-toughness and halogen-free flame retardant polypropylene cable material is prepared from the following components in parts by weight: 100 parts of polypropylene, 0.5 to 1 part of an antioxidant, 1 to 1.5 parts of a lubricant, 0.2 to 0.7 part of an ultraviolet absorbent, 10 to 15 parts of a plasticizer, 4 to 4.5 parts of a compatilizer, 0.1 to 0.6 part of a nucleating agent, 6 to 11 parts of a flexible modifier, and 11 to 16 parts of modified dickite powder. The invention further discloses a preparation method of the high-toughness and halogen-free flame retardant polypropylene cable material. The high-toughness and halogen-free flame retardant polypropylene cable material disclosed by the invention is relatively high in toughness and relatively strong in flame retardancy.

Description

technical field [0001] The invention relates to a polypropylene cable material, in particular to a high-toughness, halogen-free flame-retardant polypropylene cable material and a preparation method thereof. Background technique [0002] Wires and cables usually appear in different application fields in our daily life. From the perspective of use, they can be divided into: power cables (low, medium and high voltage), telephone wires, automobile wires, mining cables, etc. A simple wire is just a (bundle) copper wire and a layer of insulation. With the segmentation of the market, various special cables, such as shipping, underground, underwater, aerospace and other high-performance cables, have emerged. The current cable is not a simple metal plus a single layer of insulation, but at least the double layer has very different characteristics, divided into insulation material (thermal conductivity and insulation) and sheath material (protective layer). Polypropylene cable materi...
