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

Abstract

The invention relates to a fiber-reinforced pipe used for a coal mine. The fiber-reinforced pipe is composed of an inner lining pipe, a fiber layer, an outer lining pipe and a fiber layer from inside to outside in sequence. The inner lining pipe comprises, by weight, 100 parts of polyethylene, 35-64 parts of melamine-formaldehyde resin, 5-12 parts of toughening agents, 6-18 parts of plastic anti-aging agents and 10-30 parts of water. The outer lining pipe comprises, by weight, 100 parts of polyethylene, 20-30 parts of polyvinyl chloride, 12-15 parts of polyolefin, 1.2-5 parts of carbon monofluoride and 0.6-1.5 parts of white oil. The pipe is good in flame resistant performance, high in anti-static performance, simple in structure, convenient to install and long in service life. The invention further provides a manufacturing method of the fiber-reinforced pipe.

Description

Technical field [0001] The invention relates to a fiber reinforced tube, in particular to an antistatic fiber reinforced tube and a production method thereof, and belongs to the technical field of pipelines. Background technique [0002] Pipes are needed in many projects. Traditional pipelines are mostly steel pipes, especially high-pressure pipelines. Due to the heavy weight of steel pipes, installation and transportation are very inconvenient. In addition, because steel pipes are easily corroded, their service life is short and their use is limited. For example, underground coal mines have complicated environments and The danger is high, therefore, the antistatic requirements and flame retardant requirements for drainage pipes, filling pipes or gas drainage pipes in underground mines are relatively high. [0003] With the development of new materials and new processes, a kind of pipeline has recently appeared. The pipeline includes an inner liner. The inner liner is processed f...
