Problems solved by technology

[0003] Due to the needs of environmental protection and safety, the current power tube needs a high toughness, halogen-free, low-smoke and flame-retardant power tube, so that in the event of a safety accident, the power tube can reduce the occurrence of fire and other safety accidents, and at the same time reduce the damage to the environment , but the current high-toughness, halogen-free, low-smoke, flame-retardant power tubes cannot be uniformly stirred during the production process, resulting in the inability of all materials to be evenly fused during melting, so that the performance of the power tubes cannot be balanced. , and the production efficiency cannot be improved, so that the production of power tubes cannot adapt to the increasing production demand

Abstract

The invention discloses a high-toughness halogen-free low-smoke flame-retardant power tube and a preparation method thereof. Modified resin is prepared from the following raw materials in parts by weight: 75-90 parts of isotactic polyethylene resin, 8-11 parts of ethylene glycol monophenyl ether superfine powder, 4-6 parts of nitrile rubber, 4-6 parts of halogen-free flame retardant powder, 1-4 parts of a synergistic flame retardant and 6-18 parts of ultrahigh molecular weight polyethylene resin. Raw material particles with overlarge particle sizes are conveyed into a material storage box to be crushed again, the screened raw materials are conveyed into a mixing mechanism, the raw materials entering a material mixing tank are mixed uniformly through circular stirring, the raw material particles entering a melting tank are subjected to circular stirring from inside to outside, the melting tank is kept vacuum through a vacuum pump, the melting speed of the raw material particles is increased, and the high-toughness halogen-free low-smoke flame-retardant electric power tube is obtained through extrusion, so that the situation that the performance of the electric power tube is uneven due to uneven raw materials is avoided, and the yield of the electric power tube is greatly increased.

Description

technical field [0001] The invention relates to the technical field of power tube production, in particular to a high-toughness, halogen-free, low-smoke, flame-retardant power tube and a preparation method thereof. Background technique [0002] During the development of modern society, the demand for energy continues to expand, and electric energy is used more and more widely as an energy source that can be transmitted over long distances. When installing cables and other cable equipment, it is often necessary to bury the cables in power pipes, As an important part of the protection equipment, the power pipe does not need a lot of dredging, excavation and damage to the road surface. It is necessary to lay pipelines, cables and other construction projects in special areas such as roads, railways, buildings, and river beds. It has the characteristics of high temperature resistance and external pressure resistance, and is suitable for high-voltage transmission lines and cables ...
