Abstract

The invention discloses a high-temperature-resistant and corrosion-resistant rubber tube and a preparing method thereof. Low-density polyethylene, ultra-high molecular weight polyethylene and macromolecular crosslinked polyethylene are used as raw materials, a lining film is prepared from chemical substances which have excellent bonding performance and are obtained after scientific compounding and vulcanization of a rubber pipe, and corona treatment is conducted on the bonding surface of the lining film and the bonding surface of the rubber pipe at the same time; glass fiber reinforced plastic reinforced fibers having the radiation protection performance are combined on the surface layer, so that the surface of the rubber pipe has the excellent radiation protection performance, and potential safety hazards caused by ionization radiation of a delivery pipeline are avoided; and finally the high-temperature-resistant and corrosion-resistant rubber tube which is provided with the firmly-bonded lining film, has the good radiation protection performance and can be used for delivering liquefied petroleum gas (LPG), liquefied natural gas (LNG) and extremely corrosive chemical solvent is prepared. The absorptivity to X rays and gamma rays in nuclear radiation and various neutrons of the hose can reach 97.5%-99.5%, and the binding force of the lining film and the rubber layer reaches 160-180 N/25mm.
