▎ 摘　　要

NOVELTY - The method involves flame-retardant mixture containing 1-30 pts. wt. antimony trioxide, 1-3 pts. wt. molybdenum disulfide, 1-20 pts. wt. aluminum hydroxide or magnesium hydroxides, 0.1-5 pts. wt. stearic acid, 0-20 pts. wt. antioxidant, 0.1-3 pts. wt. carbon nanotube (CNT) or graphene is prepared, and 3-10 pts. wt. phenolic resin is prepared with respect to 100 pts. wt. filling material in which recycled polyethylene foam chip and flame retardant mixture are mixed. The filling material is mixed with phenol resin as a base, and a molding material is kneaded for 25-35 minutes in a kneader. An insulating material surrounding a liquefied natural gas (LNG) transport pipe is coated with fiber-reinforced plastic to form an outer shell. USE - The flame-retardant cold insulation article is useful for liquefied natural gas (LNG) deck pipe. ADVANTAGE - The method enables manufacture of flame retardant cold insulation article having excellent flame retardance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for flame-retardant cold storage article prepared using the recycled polyethylene foam. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating method for manufacturing a flame-retardant cold insulation article (Drawing includes non-English language text).
