[0026] A preparation method of a fiber reinforced pipe used in a mine, the preparation method is as follows:
[0027] (1) Equipped with toughening agent, nano-titanium dioxide and ABS resin are mixed in a weight ratio of 1:1.5 to prepare the toughening agent;
[0028] (2) Add 100 parts by weight of polyethylene, 55 parts of melamine formaldehyde resin, 10 parts of toughening agent, 12 parts of plastic anti-aging agent and 15 parts of water into the extruder, and extrude the inside Liner, the extrusion temperature is 120-155℃;
[0029] (3) After mixing the aromatic polyamide fiber and glass fiber uniformly in a weight ratio of 1:1.5, add it to the winding machine, and wind the mixed fiber evenly and across the outer peripheral surface of the liner tube to form a fiber layer. Rotation speed root is 220 rpm;
[0030] (4) Add 100 parts by weight of ethylene, 25 parts of polyvinyl chloride, 12 parts of polyolefin, 2 parts of fluorinated graphite, and 0.8 parts of white oil into the extrud...

[0033] A preparation method of a fiber reinforced pipe used in a mine, the preparation method is as follows:
[0034] (1) Equipped with a toughening agent, nano-titanium dioxide and ABS resin are mixed in a weight ratio of 1:2 to prepare the toughening agent;
[0035] (2) Add 100 parts by weight of polyethylene, 49 parts of melamine formaldehyde resin, 12 parts of toughening agent, 16 parts of plastic anti-aging agent and 20 parts of water into the extruder, and extrude the inside Liner, the extrusion temperature is 135℃;
[0036] (3) After mixing the aromatic polyamide fiber and the glass fiber uniformly in a weight ratio of 1:2, add it to the winding machine, and wind the mixed fiber evenly and across the outer peripheral surface of the inner lining tube to form a fiber layer. Rotation speed root is 220 rpm;
[0037] (4) Add 100 parts by weight of ethylene, 28 parts of polyvinyl chloride, 14 parts of polyolefin, 3 parts of fluorinated graphite, and 1.2 parts of white oil into the e...
