Radiation-resistant rubber pipe and preparation method thereof

Abstract

The invention discloses a radiation-resistant rubber pipe and a preparation method thereof. According to the radiation-resistant rubber pipe and the preparation method thereof, a lining film is prepared from low-density polyethylene, ultrahigh molecular weight polyethylene and macromolecular cross-linked polyethylene, which serve as raw materials, and chemical substances which have an excellent bonding property after scientific compounding and rubber pipe curing, meanwhile, a lining film bonding face and a rubber pipe bonding face are subjected to corona treatment, and a surface layer is compounded with glass fiber reinforced plastic reinforced fibers with radiation-resistant performance, so that the surface layer of the rubber pipe has excellent radiation resistance, potential safety hazards resulting from the ionizing radiation of a conveying pipeline are solved, and finally, the rubber pipe, which has the firmly-bonded lining film, can be used for conveying LPG, LNG and strongly-corrosive chemical solvents and is high in radiation resistance, is prepared; the ratio of absorption to X rays, gamma rays and various neutrons in nuclear radiation of the rubber pipe can reach up to 97.5-99.5%, and the bonding force (N/25mm) between the lining film and a rubber layer reaches 160-180.

Problems solved by technology

[0008] The technical problem solved by the present invention is to overcome the defects of the existing corrosion-resistant rubber tubes, using low-density polyethylene (LLDPE), ultra-high molecular weight polyethylene (UHMWPE) and polymer cross-linked polyethylene as the main raw materials, scientifically compounding and After vulcanization of the rubber tube, the lining film is prepared from chemical substances such as polyimide, tetraethylpentamine, α-sulfo fatty acid alkyl ester salt, epoxy resin, SBR latex, rosin, etc., which have excellent bonding properties. Corona treatment is carried out on the bonding surface of the inner lining film and the bonding surface of the rubber tube to enhance its cohesiveness, and the surface layer is compounded with fiberglass reinforced fiber with radiation-proof performance, so that the surface layer of the rubber tube has excellent anti-corrosion properties. Radiation, especially to solve the potential safety hazards caused by ionizing radiation for pipelines transporting oil and natural gas, and finally prepare a kind of rubber with firm bonding of the lining film, which can transport LPG, LNG and strong corrosive chemical solvents, and strong radiation resistance Tube
