The present invention relates to a high-tolerance composite hose and a production process thereof, belonging to the technical field of polymer composite materials. The composite hose comprises an aluminum foil and a high-tolerance inner film composited on its surface. The high-tolerance inner film is a copolymer of low molecular weight polyethylene, monomer 1, and monomer 2. The monomer 1 molecule contains branched fluorine-containing groups and double bonds. After copolymerization, fluorine groups are introduced on the outside of the main chain to protect the main chain and improve tolerance to organic solvents. Monomer 2 uses diethanolamine and diallyl sulfide as raw materials, and undergoes an addition reaction under the catalysis of sodium ethoxide to produce an intermediate containing branched hydroxyl groups. Subsequently, double bonds are introduced into the ends using acryloyl chloride for modification. The double bonds participate in copolymerization. The sulfur-containing and nitrogen-containing structures in the middle of the monomer 2 molecule have a chelating effect with the aluminum foil, forming an anchoring effect on the polymer after composite, so that the high-tolerance inner film has a strong adhesion strength to the aluminum foil.
