Problems solved by technology

[0002] Polypropylene PP resin has good processability, toughness, chemical resistance, light weight and low price, so it has a wide range of applications, and it is also especially suitable for cable material conduits; however, due to the compressive properties of polypropylene PP resin, The impact resistance is poor, and polypropylene PP resin is a flammable material with an oxygen index of 18.0%. When the oxygen index is between 20% and 27%, the material will self-extinguish when it burns. When the oxygen index is greater than 27%, the material will It will be difficult to burn, so polypropylene (PP) resin is blended with appropriate flame-retardant materials to increase its oxygen index, so as to achieve flame-retardant purposes. For this reason, we propose a modified polypropylene plastic cable for flame-retardant non-excavation catheter

Abstract

The invention discloses a flame-retardant trenchless modified polypropylene plastic cable conduit. The flame-retardant trenchless modified polypropylene plastic cable conduit is prepared from the following components in parts by weight: 100 parts of PP resin, 2 to 20 parts of octabromo ether, 2 to 8 parts of antimony oxide, 10 to 15 parts of nano carbonic acid, 0.1 to 1.0 part of a coupling agentKH-550, 0.1 to 1.0 part of an antioxidant 1010, 0.1 to 1.0 part of zinc stearate and 0.1 to 1.0 part of barium stearate. The flame-retardant trenchless modified polypropylene plastic cable conduit hasrelatively strong flame retardancy, also has relatively strong impression and rigidity, can improve the impact resistance of the cable conduit, is more beneficial to processing, and can prolong the service life of the flame-retardant trenchless modified polypropylene plastic cable conduit.
