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
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

example 1

[0021] A pressure-resistant polyethylene pipe and its preparation method. The preparation method is as follows: first, mix dimethyl tin and dioctyl tin at a mixing ratio of 11:9 (by mass ratio) to obtain a heat stabilizer. Then mix ABS, SBS and EVA at a mixing ratio of 13:7:19 (by mass ratio) to obtain a toughening agent. Then put 120 parts of high-density polyethylene, 2.5 parts of heat stabilizer, 17 parts of toughening agent, 6 parts of stearic acid, 5 parts of paraffin, and 11 parts of active calcium carbonate into the mixer in turn, stirring time: 25min, stirring speed: 660r / min. Put the stirred mixture into a twin-screw extruder for blending and granulation. The temperature range of each section of the extruder is: 160°C. Finally, the granulated granules are extruded into finished pipes through a single-screw extruder. The temperature of the barrel of the single-screw extruder is 180°C, the temperature of the mold is 190°C, and the temperature of the die mouth is 165°C....

[0023] A pressure-resistant polyethylene pipe and its preparation method. The preparation method is as follows: first, mix dimethyl tin and dioctyl tin at a mixing ratio of 11:9 (by mass ratio) to obtain a heat stabilizer. Then mix ABS, SBS and EVA at a mixing ratio of 13:7:19 (by mass ratio) to obtain a toughening agent. Then put 130 parts of high-density polyethylene, 1.5 parts of heat stabilizer, 15 parts of toughening agent, 5 parts of stearic acid, 3 parts of paraffin, and 12 parts of active calcium carbonate into the mixer in sequence, stirring time: 25min, stirring speed: 660r / min. Put the stirred mixture into a twin-screw extruder for blending and granulation. The temperature range of each section of the extruder is: 170°C. Finally, the granulated granules are extruded into finished pipes through a single-screw extruder.

Description

technical field [0001] The invention relates to a rubber glove, in particular to a pressure-resistant polyethylene pipe and a preparation method thereof. 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. 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, Due to its low pressure bearing pe...
