Flame-retardant antistatic polyethylene pipe and making method thereof

Abstract

The invention discloses a flame-retardant antistatic polyethylene pipe and a making method thereof. The pipe comprises the following raw materials by weight: 40%-60% of high density polyethylene (HDPE), 10%-20% of zinc borate, 20%-40% of special nanometer conductive carbon black, 1%-5% of a coupling agent, and 1%-5% of auxiliary agents. The flame-retardant antistatic polyethylene pipe provided by the invention has good antistatic and flame-retardant synergistic effect, excellent antistatic properties and flame retardance, light weight, soft texture, good toughness, coilability, corrosion resistance, resistance to erosion of various chemical media, smooth inner wall, and small resistance. Difficult to scale in use, the pipe has better wear resistance than rubber tubes and pure polyethylene pipes, and has simple ingredients and is easy to prepare. The pipe provided by the invention can completely replace steel pipes to be widely used in drainage, water supply, air compression and gas drainage, and has the advantages of no toxicity and sanitation, light weight, and convenient construction.

Description

technical field [0001] The invention relates to a pipe, in particular to a flame-retardant and antistatic polyethylene pipe and a manufacturing method thereof. technical background [0002] In recent years, due to the advantages of low price, light weight, convenient installation, and environmental protection, polyethylene pipes have been widely used in various fields due to the promotion of national policies. Plastic pipes have the advantages of good corrosion resistance, low cost, light weight, long life, and convenient installation. However, plastic pipes are also prone to static electricity, flammable, low pressure resistance, poor impact resistance, complex production formula, and inconvenient operation. Disadvantages, therefore, the polyethylene material needs to be further adjusted to improve and perfect its performance. [0003] In addition to the physical and mechanical properties of general plastic pipes, polyethylene pipes for mining should also meet the special ...

Problems solved by technology

With the continuous development of carbon black technology, in recent years, a small amount of carbon black can be added to the composite material to obtain a good antistatic effect. However, due to the large specific surface of the conductive carbon black, adding it to the resin will still seriously Affect the melt viscosity of the composite material, and there will be excessive torque and unstable extrusion during the extrusion process.
