[0002] At present, the power cable protection tubes and communication optical cable protection tubes used in the market generally use polyethylene PE pipes, polypropylene PP pipes, polyvinyl chloride PVC pipes, and glass steel pipes. These pipes are of various colors and have their own characteristics. Ethylene PE pipes are soft but have insufficient tensile strength, polyvinyl chloride PVC pipes have insufficient impact resistance, glass steel pipes pollute the environment, ordinary polypropylene PP pipe rings have insufficient rigidity and insufficient tensile strength, etc. In order to solve the shortcomings of the above-mentioned pipes, the production of more High-quality products, people continue to explore and improve, pursue more perfect, infinite innovation

Abstract
The invention relates to an ultra-strong MPP (modified polypropylene) power communication pipe and a preparation method for the same. The ultra-strong MPP power communication pipe comprises PP (polypropylene), PE (polyethylene), an EPDM (ethylene propylene diene monomer), an inorganic filler, a silane coupling agent, an antioxidant and an auxiliary antioxidant. The preparation method comprises the following steps: feeding the inorganic filler into a high-speed mixer for stirring; feeding EPDM powder into the high-speed mixer for stirring; spraying the silane coupling into the high-speed mixer by virtue of a metering pump; feeding the PP and the PE into the high-speed mixer for stirring; feeding the antioxidant and the auxiliary antioxidant into the high-speed mixer for stirring; preparing a toughened raw material; extruding the mixed toughened raw material by virtue of an extruder. The ultra-strong MPP power communication pipe and the preparation method for the same have the beneficial effects that the components in the formula cooperate to strengthen the tensile strength of the pipe by 60 percent, improve the ring stiffness by 10 percent, improve the surface hardness by 50 and achieve high compression resilience, small deformation, high heat and aging resistance and high electric insulativity.
