Abstract

The invention discloses a flame retardation polypropylene insulation cable material. The flame retardation polypropylene insulation cable material is mainly prepared from, by mass, 107-116 parts of polypropylene, 5-10 parts of white carbon black, 3-8 parts of sulfur, 4-9 parts of zinc borate, 6-10 parts of calcium stearate, 6-12 parts of carboxymethylcellulose sodium, 5-11 parts of epoxidized soybean oil, 17-23 parts of aluminum hydroxide, 10-16 parts of diatomite and 8-13 parts of lignin. The above obtained product has the advantages of good mechanical performances, impact resistance, corrosion resistance, stretching resistance, high flame retardation property, good insulation property, and realization of safe and effective protection of cables.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a flame-retardant polypropylene insulating cable material and a preparation method thereof. Background technique [0002] The plastic used for wire and cable insulation and sheath is commonly known as cable material. Traditional flame-retardant cables generally use polyvinyl chloride as the sheath. Although polyvinyl chloride material has the characteristics of good flame retardancy, low price, and good craftsmanship, it contains Halogen, when burned, will release a large amount of hydrogen halide gas and dense smoke, causing the "secondary hazard" of the fire, thereby increasing the loss of the fire. In particular, many scientific studies have confirmed that the damage caused by halides to human health and the environment has become more and more serious, and people are paying more and more attention to environmental protection. The halogen-free low-smoke, halogen-free and flame-...
