Problems solved by technology

The steel pipe is very inconvenient to install and transport due to its heavy weight; in addition, because the steel pipe is easily corroded, its service life is short and its use is limited, such as underground coal mines. The risk is high, therefore, the antistatic requirements and flame retardant requirements for underground drainage pipes, filling pipes or gas drainage pipes are relatively high
[0003] With the development of new materials and new processes, a pipeline has recently appeared. The pipeline includes a liner, and the liner is made of thermoplastic materials. Although the structure of the pipeline is light and easy to install, Cannot be used in mines due to its low pressure resistance

Embodiment 1

[0037] A processing method for fiber-reinforced pipes used in mines, a. processing flame-retardant and antistatic polyethylene liner pipes;

[0038] a1. Put special raw materials for flame retardant and antistatic polyethylene (polyethylene 70%, flame retardant 26%, antioxidant 2% and coupling agent 2%) into the extruder, extrude through the extruder, and heat During the process, the extrusion temperature of the flame-retardant and antistatic polyethylene pipe is controlled within the range of 160°C; after extrusion, it undergoes vacuum shaping, cooling, traction, and cutting; b. Use a winding machine to evenly cross the outer peripheral surface of the liner Winding fibers to form a fiber reinforced layer; the rotation speed of the fibers is determined according to different pipe diameters, generally 180 rpm; c, through the extruder, the flame-retardant antistatic polyethylene special material (polyethylene 70 %, flame retardant 26%, antioxidant 2% and coupling agent 2%) extru...

Embodiment 2

[0041] A processing method for fiber-reinforced pipes used in mines, a. processing flame-retardant and antistatic polyethylene liner pipes;

[0042] a1. Put special raw materials for flame retardant and antistatic polyethylene (polyethylene 70%, flame retardant 28%, antioxidant 1% and coupling agent 1%) into the extruder, extrude through the extruder, and heat During the process, the extrusion temperature of the flame-retardant and antistatic polyethylene pipe is controlled within the range of 160 °C; it undergoes vacuum shaping, cooling, traction, and cutting in sequence; b. Winding fibers that are uniformly crossed on the outer peripheral surface of the inner liner by a winding machine , forming a fiber reinforced layer; the rotation speed of the fiber is determined according to different pipe diameters, generally 250 revolutions per minute; c, through the extruder, the flame-retardant and antistatic polyethylene special material (polyethylene 70%, resistance Combustion agen...

Abstract

The invention provides a fiber reinforced pipe for a mine and a production method thereof. The fiber reinforced pipe comprises a lined pipe, wherein the lined pipe is made of an antiflaming and antistatic special polyethylene material, so that the fire resistance and anti-static electricity performance of a pipe are improved; therefore, the safety of the pipe is improved; the weight of the polyethylene is light, so that the pipe can be conveniently installed and transported; moreover, the fiber reinforced pipe has a simple structure and can be processed conveniently; and the processing method of the fiber reinforced pipe is easy to operate, and can improve the fire resistance of the fiber reinforced pipe.

Description

technical field [0001] The invention relates to a fiber-reinforced pipe, in particular to an antistatic fiber-reinforced pipe and a production method thereof, belonging to the technical field of pipes. Background technique [0002] Pipelines are used in many projects. Most of the traditional pipelines are steel pipes, especially high-pressure pipelines. The steel pipe is very inconvenient to install and transport due to its heavy weight; in addition, because the steel pipe is easily corroded, its service life is short and its use is limited, such as underground coal mines. The risk is high, therefore, the antistatic requirements and flame retardant requirements for underground drainage pipes, filling pipes or gas drainage pipes are relatively high. [0003] With the development of new materials and new processes, a pipeline has recently appeared. The pipeline includes a liner, and the liner is made of thermoplastic materials. Although the structure of the pipeline is light...
