Double-layer reinforced modified polyolefin drpo corrugated pipe for buried drainage and sewage

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.

Description

technical field

[0001] The invention belongs to the field of polymer composite materials, and in particular relates to a double-layer reinforced modified polyolefin DRPO corrugated pipe for buried drainage and sewage discharge. Background technique

[0002] At present, my country's drainage pipe network system is still dominated by traditional reinforced concrete pipes, ceramic pipes, and cast iron pipes, but their construction is difficult and the connections between pipes are complicated, often resulting in huge construction waste. Especially in long-term use, often due to corrosion, damage, leakage, especially large-area sewage leakage, less and less underground water sources have been seriously polluted. Solving the problem of water shortage and pollution in the city is related to the sustainable development of the city, and it is also a major issue for the current and long-term development of our country. According to the development of plastic pipes in developed count...
