摘　　要：中国拥有丰富的黑色页岩矿物资源,制备和开发黑色页岩/聚合物复合材料对提高其利用价值及实现可持续发展有重要意义。本文首次利用热重分析对黑色页岩/HDPE复合材料的非等温热分解动力学进行了研究,运用Kissinger法和Crane法计算了黑色页岩/HDPE复合材料的热分解动力学参数。研究表明,黑色页岩对复合材料的热分解行为无明显影响,黑色页岩/HDPE复合材料热分解反应均为一阶热分解反应,热分解活化能在269.31-311.88kJ/mol之间,与纯HDPE相近。因此,黑色页岩作为填料不会增加复合材料热分解的风险,为黑色页岩的进一步开发和应用提供了基础。Preparation and exploration of black shale-polymers composites is of significant importance for the improvement of the value of black shale and sustainable development of black shale mine since China has abundant black shale mineral resources.Non-isothermal thermal decomposition of black shale/HDPE composites was studied for the first time by thermogravimetric analysis.The Kissinger and Crane models are used to obtain the kinetics parameters of the thermal decomposition reaction of black shale/HDPE composites.The results showed that there are no obvious effects of black shale on the thermal decomposition of black shale/HDPE composites.Thermal decomposition of black shale/HDPE composites is a first-order reaction and the reaction activation energy is between 269.31 and 311.88 kJ/mol,which keeps in accordance with pure HDPE.Therefore,a black shale wouldn’t damage the thermal stability of black shale-polymers composites.This work paves a way for further exploration and application of black shale.
