Basalt fiber reinforced modified polyolefin double-wall hollow twined drainage pipe

Abstract

The invention discloses a basalt fiber reinforced modified polyolefin double-wall hollow twined drainage pipe which comprises, in weight percentage, 72%-85% of polyolefin, 5%-10% of BPOE and 10%-18% of basalt fibers. The BPOE comprises, by weight, 100 parts of ethylene-octene copolymer, 2-7 parts of styrene, 3-6 parts of glycidyl methacrylate and 0.1-0.4 part of dicumyl peroxide. The ring stiffness of the prepared pipe is SN8 8.7-9.5, SN10 10.6-11.8, SN12.5 13.1-15.2 and SN16 16.6-18.5, the impact property of the pipe is (23 DEG C) 7 / %, the pipe has ring flexibility, a test sample is smooth, a pipe wall is free from cracking, bubbles, layering and cracking are avoided during oven test, and creep rate is 3.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a basalt fiber-reinforced modified polyolefin double-flat-wall hollow winding drainage 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. Drawing lessons from the construction experience of drainage pipe networks in de...
