Abstract

The invention discloses a modified polyolefin DRPO steel-plastic reinforced wrapped drainage blow-off pipe. The pipe is composed of an inner wall layer and an outer wall layer, the two of which are fitted and then twisted, wherein the outer wall is formed by use of a modified polyolefin material covered steel strip; the modified polyolefin material is prepared from the following raw materials in parts by weight: 50-75 parts of polyolefin, 5-10 parts of modified polyolefin elastomer BPOE and 20-40 parts of active talcum powder; the inner wall material is HDPE or PPR added with 15-25% of ultra-high molecular weight polyethylene UHMW-PE. The modified polyolefin DRPO steel-plastic reinforced wrapped drainage blow-off pipe is mainly used as a buried drainage blow-off pipe.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and in particular relates to a modified polyolefin DRPO steel-plastic reinforced winding drainage and sewage pipe. 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 countries abroad and the vig...
