High Thermal Conductivity Polyethylene Pipe
Composites of HDPE/graphite were prepared through blending high density polyethylene (HDPE) with surface activating treatment graphite by self-made compatibilizer and titanate coupling agent. It was studied that the kinds of matrix resin, coupling agent, compatibilizer and graphite particle size and its content effected on tensile strength, impact strength and microstructure of composites, especially, thermal conductivity. It showed that the higher thermal conductivity of matrix resin contributed to enhancing the systems thermal conductivity. Compatibilizer improved immensely compatibility of the system. Compared with spherical inorganic filler, scaly inorganic filler improved thermal conductivity. With the increase of graphite particle size, the tensile strength of composites was decreased slightly; nevertheless the thermal conductivity was greatly improved. The thermal conductivity of the composites obviously was increased with increasing content of graphite. When the content of graphite was 40phr, the thermal conductivity of composites reached the value of 1.198 W/m·K, which was increased 170％ more than that of neat HDPE.
