摘　　要：为了研究黑色页岩作为填料应用于塑料工业的可能性,本文对桂林地区的黑色页岩进行了成分和形貌研究,发现其为纳米层状结构,主要由二氧化硅、钾长石及有机碳组成。利用不同的偶联剂与表面活性剂改性黑色页岩,制备了黑色页岩/HDPE复合材料,并对其力学性能、形貌、体积电阻率和介电常数进行了研究。结果表明:铝酸酯偶联剂与十二烷基苯磺酸钠能够改善页岩与HDPE之间的相容性,当页岩填充量为50份时,黑色页岩/HDPE复合材料的拉伸强度、冲击强度和体积电阻率有所降低,拉伸强度仍保持在23.47 MPa,冲击强度最高为6.39 kJ/m^(2),体积电阻率也可维持在10^(14)Ω·cm以上,保持了较好的力学性能和绝缘性能。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/m^(2),and the volume resistivity can also be maintained above 10^(14)Ω·cm,maintaining good mechanical properties and insulating properties.
