NOVELTY - Corrugated pipe comprises nano-material modified high-density polyethylene, maleic anhydride grafted polyethylene and auxiliary agent. The mass ratio of the nano-material modified high-density polyethylene and maleic anhydride grafted polyethylene is (12-14):1 and the weight of the auxiliary agent accounts for 10-23 wt.% of the total weight of the nano-material modified high-density polyethylene and maleic anhydride grafted polyethylene. The auxiliary agent comprises 10-15 pts. wt. calcium carbonate inorganic filler, 5-10 pts. wt. color master batch, 2-5 pts. wt. lubricant, 1-3 pts. wt. dispersant, 4-6 pts. wt. plasticizer, 2-5 pts. wt. light stabilizer and 2-4 pts. wt. antioxidant. USE - Used as corrugated pipe. ADVANTAGE - The corrugated pipe has improved anti-ultraviolet, anti-oxidation and heat resistance properties and delayed aging and long service life.
