NOVELTY - Method for preparing power cable materials involves (i) adding polypropylene and ethylene-propylene rubber, ethylene-octene elastomer and acidified attapulgite to an internal mixer and mixing to obtain a mixture and (ii) adding the obtained mixture to the high-speed mixer, uniformly mixing, again adding it to the twin-screw extruder and extruding it into a molten state, completely melting the mixture and extruding it to the injection molding machine for injection molding. USE - The method is used for preparing power cable materials suitable for the application of ships. ADVANTAGE - The method has excellent mechanical properties and excellent corrosion resistance.
