Problems solved by technology

[0002] Under the existing technology, the health of drinking water has been paid more attention by people. As the pipe material for transporting drinking water, it must be environmentally friendly and non-polluting, which requires its material to be more stable. At present, the best water pipe material is PP-R tube, but the high cost of this tube is not conducive to popularization

Embodiment 1

[0016] A manufacturing process of a water pipe dedicated to drinking water made of composite materials, comprising the following steps:

[0017] A. After mixing the following ingredients according to the mass percentage, heat and mix: polyphenylene sulfone 26%, polyether sulfone 27%, polybutene 27%, and add machine fluorine processing aid (PPA2800) 10%, carbon fiber 5% %, non-sulfur organotin 3% and dioctyl phthalate 2%;

[0018] B. The above mixture is extruded with an extruder at a temperature of 220 degrees Celsius.

Embodiment 2

[0020] The difference from Example 1 is that the plasticizer is dibutyl phthalate.
