[0002] In modern buildings, the drainage system is an indispensable part, which is responsible for discharging domestic sewage, rainwater, etc. out of the building.

[0003] Traditional drainage pipes, especially in high-rise buildings, will generate a lot of noise due to the fast water flow during use, seriously affecting the comfort of residents.

[0004] Therefore, we propose a noise reduction drainage pipe and a preparation method thereof to solve the above problems. Summary of the invention
