Abstract

The invention discloses a high-flame-retardance MPP communication and power cable tube and a processing technology thereof, and relates to the technical field of cable tubes. The high-flame-retardance MPP communication and power cable tube is prepared from the following raw materials in parts by weight: 30-40 parts of acrylic resin, 40-50 parts of ultrahigh molecular weight polyethylene resin, 3-5 parts of ethylene propylene diene monomer, 0.1-0.3 part of polyethylene wax, 4-6 parts of magnesium hydroxide, 2-4 parts of calcium powder, 2-4 parts of argil and 0.1-0.3 part of pigment. According to the high-flame-retardance MPP communication and power cable tube and the processing technology thereof, the ethylene propylene diene monomer is added into the acrylic resin and the ultra-high molecular weight polyethylene resin, so that the impact resistance of the material can be improved, and the low-temperature brittle temperature of the prepared cable tube is extremely low; the polyethylene wax is used as a lubricant, so that the friction force between a material melt and processing equipment can be reduced, the processability of the material is improved, and the added magnesium hydroxide, calcium powder and argil are matched, so that the flame retardance of the cable tube can be effectively enhanced.

Description

technical field [0001] The invention relates to the technical field of cable tubes, in particular to a highly flame-retardant MPP communication and power cable tube and its processing technology. Background technique [0002] MPP power pipes are divided into ordinary type and reinforced type, and reinforced type is divided into excavated pipe and non-excavated pipe. The so-called MPP non-excavated pipe is also called MPP jacking pipe, MPP dragging pipe, and MPP traction pipe. [0003] Most of the existing cable tubes are made of propylene resin and ultra-high molecular weight polyethylene resin. The impact resistance of the cable tube is poor, and the cable tube is easy to be brittle at low temperature, and there is a gap between the material melt and the processing equipment. The friction force is relatively large, the processing performance is poor, and the overall flame retardancy is average. Therefore, the present invention proposes a high flame retardancy MPP communicat...
