The invention discloses a waterproof sealing flexible hot melt adhesive and a preparation method thereof, and relates to the field of hot melt adhesives. The waterproof sealing flexible hot melt adhesive is prepared from 65 to 70 parts of EVA (Ethylene Vinyl Acetate) resin, 20 to 22 parts of POE (Polyolefin Elastomer), 5.5 to 6.5 parts of maleic anhydride grafted POE, 4.2 to 4.8 parts of SIS (Styrene Isoprene Styrene) block copolymer, 1.2 to 1.8 parts of maleic anhydride grafted SIS block copolymer, 15 to 20 parts of tackifier, 4 to 6 parts of viscosity modifier and 1 to 1.5 parts of antioxidant. According to the hot melt adhesive, the EVA resin, the POE polyolefin elastomer and the SIS block copolymer are matched, and the compatibility of the EVA resin, the POE polyolefin elastomer and the SIS block copolymer is improved through the maleic anhydride grafted POE polyolefin elastomer and the maleic anhydride grafted SIS block copolymer, so that the hot melt adhesive with a good bonding effect on a film-coated paper box and a good low-temperature-resistant effect can be obtained; and the bonding durability of the film-coated paper box in a humid environment or a low-temperature environment can be effectively improved.

The invention relates to the technical field of cable manufacturing, and particularly discloses an aerial insulated cable and a production process thereof, the aerial insulated cable comprises a conductor, the outer surface of the conductor is fixedly coated with a shielding layer, the outer side of the shielding layer is fixedly coated with an insulating tube, and the outer side of the insulating tube is provided with an outer sheath. The outer surface of the insulating tube is wrapped and supported through the arc-shaped inner surfaces of the limiting tubes and the reinforcing strips, so that the insulating tube is fixed in the outer sheath, the situation that the overall structural stability of the cable is affected due to displacement of the insulating tube in the outer sheath is avoided, the inner surface of the outer sheath is supported through the supporting strips and the reinforcing strips, and the service life of the cable is prolonged. The overall structural strength of the outer sheath can be enhanced, the situation that the normal work of the cable is affected by permanent deformation of the outer sheath is avoided, meanwhile, gaps are formed among the limiting pipes, the supporting strips and the reinforcing strips, heat generated when the cable works can be dissipated, and the phenomenon that the outer sheath swells when the cable works normally is avoided.
