Problems solved by technology

[0003] However, when UPVC pipes are used in places where static electricity is easily generated, such as coal mines, it will cause fire or gas explosion due to the accumulation of static electricity.
In addition, UPVC pipes have poor tensile strength and toughness, and poor impact resistance. They are often impacted and collided during use, and cannot be replaced frequently, which cannot meet actual needs.

Abstract

The invention discloses a flame-retardant and anti-static UPVC electrician tube comprising a UPVC electrician tube base layer, a flexible anti-seismic layer, a first anti-static layer, and a second anti-static layer. The flexible anti-seismic layer and the first anti-static layer are sequentially arranged on the outer surface of the UPVC electrician tube base layer from inside to outside. The second anti-static layer is arranged on the inner surface of the UPVC electrician tube base layer. The UPVC electrician tube base layer comprises the following raw materials, by weight, 50-70 parts of UPVC, 20-40 parts of butyl acrylate, 10-30 parts of maleic anhydride polymers, 6-17 parts of toughening modifier, 5-10 parts of cross-linking agent, 3-5 parts of halogen-free flame retardant, and 3-5 parts of smoke suppressor. Through the scheme, the flame-retardant and anti-static UPVC electrician tube is flame-retardant and anti-static, has durable and good shock resistance, is applicable to coal mines and other occasions, and can completely eradicate fire or gas explosion caused by electrostatic accumulation.

Description

technical field [0001] The invention relates to the field of electrical pipes, in particular to a flame-retardant and antistatic UPVC electrical pipe. Background technique [0002] Flame retardant insulating electrical bushing is a pipe made of electrical insulating material used to protect and guarantee wire or cable wiring in building electrical installation engineering, which allows wire or cable to penetrate or replace, and the inner and outer surfaces of the bushing are smooth. In recent years, in electrical installation and wiring, rigid polyvinyl chloride (UPVC) pipes have been more and more widely used due to their advantages such as light weight, low price, simple installation and operation, chemical corrosion resistance, and good flame retardancy. [0003] However, when UPVC pipes are used in places where static electricity is easily generated, such as coal mines, it will cause fire or gas explosion due to the accumulation of static electricity. In addition, UPVC ...
