Underground double-layer reinforced and modified polyolefin (DRPO) corrugated pipe for water draining and sewage discharging |
| abstract |
The invention discloses an underground double-layer reinforced and modified polyolefin (DRPO) corrugated pipe for water draining and sewage discharging. The pipe is formed by bonding an inner wall and an outer wall through hot melting, wherein the outer wall and the inner wall are both made of modified polyolefin materials. The modified polyolefin materials comprise, by weight, 50-75 parts of polyolefin, 5-10 parts of modified polyolefin elastomer (BPOE) and 20-40 parts of activated talcum powder. The DRPO corrugated pipe is mainly used for underground water draining and sewage discharging pipes. |
