To investigate the possibility of using black shale as a filler in the plastic industry, the composition and morphology of black shale in Guilin area were studied. It was found that black shale has nano layered structure, and was mainly composed of silica, K-feldspar, and organic carbon. The black shale/HDPE composite were prepared by modifying black shale with different coupling agents and surfactants, and their mechanical properties, morphology, volume resistivity, and dielectric constant were studied. The results show that aluminate coupling agent and sodium dodecylbenzene sulfonate can improve the compatibility between shale and HDPE. When the shale filling amount is 50 phr, the tensile strength, impact strength, and volume resistivity of black shale/HDPE composite reduce. The tensile strength remains at 23.47 MPa, the maximum impact strength is 6.39 kJ/m2, and the volume resistivity can also be maintained above 1014 Ω·cm, maintaining good mechanical properties and insulating properties.
