The invention discloses a hose for delivering liquefied natural gas and a preparation method thereof. The low-density polyethylene, ultra-high molecular weight polyethylene and high-polymer crosslinked polyethylene used as raw materials are scientifically compounded and vulcanized with a rubber tube to prepare a liner film with chemical substances with favorable bonding properties; and the liner film bonding surface and the rubber tube bonding surface are subjected to corona treatment, and radiation-resistant fiberglass-reinforced plastic reinforced fibers are compounded on the surface layer, so that the rubber tube surface layer has excellent radiation resistance, thereby solving the potential safety hazard of the transmission pipeline caused by ionizing radiation, and finally preparing the hose capable of delivering liquefied natural gas, of which the liner film has high bonding firmness and high radiation resistance. The absorptivity for X rays, gamma rays and various neutrons in nuclear radiation can be up to 97.5-99.5%, and the adhesive force between the liner film and rubber layer (N/25mm) is up to 160-180.
