The preparation method comprises that during a foaming process of a polymer nanometer composite material formed by carrying out melt co-mixing on a polymer and nanoparticles, external force is applied to make the foam hole in the material grow along the uniaxial direction in an oriented growth manner, and the polymer flows under the double induction of the external force and the foam hole growth to achieve the high orientation of the nanoparticles so as to obtain the polymer base nanometer composite material with the highly oriented nanoparticles in the polymer matrix. The method has advantages of simple operation, mild condition, high orientation degree of the nanoparticles in the prepared polymer nanometer composite material, and the like.

The invention relates to a high-temperature-resistant soft power cable for maritime oil and gas engineering and a manufacturing method thereof. The power cable is characterized in that a chemical cross-linked polyolefin insulation layer is extruded at the periphery of a tin-plated annealed stranded copper conductor to form a power cable insulation wire core; a plurality of insulation wire cores are stranded to form a cable core; an inner sheath is extruded at the periphery of the cable core; the periphery of the inner sheath inner sheath inner sheath is coated with a copper alloy wire weaving armor layer; the periphery of the copper alloy wire weaving armor layer is wrapped with a water-proof wrapping tape; and an outer sheath is extruded at the periphery of the water-proof wrapping tape. The insulation layer is prepared from the following raw material components: 12 parts of ethylene / vinyl acetate copolymer, 6 parts of high density polyethylene, 2 parts of ethylene-methacrylic acid copolymer, 0.5-1 part of cross-linking agent DCP (Dicumyl Peroxide), 0.4-0.9 part of antioxidant 1076, 0.2-0.4 part of antioxidant DNP, 0.2-1 part of lubricant stearic acid, 25-30 parts of flame retardant aluminum hydroxide, 0.6-1 part of flame retardant red phosphorus, and 0.05-0.1 parts of ultraviolet ray absorber UV-326. The insulation layer of the cable is excellent in high-temperature resistance and ageing resistance, and long in service life.
