【摘要】 将聚酯漆包线及其漆膜分别与漆膜热解所得焦炭进行共热解，利用X射线衍射、形貌分析、热重分析、CoatsRedfern积分法、红外分析等方法研究其共热解行为。结果表明，聚酯漆包线漆膜热解所得焦炭的石墨化程度较高且其表面呈褶皱状的微纳结构。虽然焦炭存在继续热解情况，但焦炭的加入不仅可以使聚酯漆膜的质量损失率提高，还可以将其活化能降低16.9%。此外，焦炭可致使聚酯漆膜热解过程中逸出更多的含有O—H、C=O等含氧官能团物质以及CO₂。研究证明，聚酯漆包线热解所得焦炭与聚酯漆包线共热解后可以进一步促进聚酯漆包线的热解，不仅有助于降低能耗还可以进一步促进废漆包线热解回收铜的发展。更多还原

【Abstract】 The pyrolysis products of the polyester enameled wire paint（coke） were separately co-pyrolyzed with the polyester enameled wire and the paint of the polyester enameled wire. And the co-pyrolysis behaviors were investigated by Xray diffraction, morphology analysis, thermogravimetric analysis, Coats-Redfern integral method, infrared analysis and other methods. The results indicated that the obtained coke displayed a high degree of graphitization with folded micronano structure on its surface. Although the coke continued pyrolyzed, it increased the weight loss of the polyester enamel paint and reduced 16. 9 % of pyrolysis activation energy when the coke co-pyrolyzed with the paint. In addition, the coke could lead to more oxygen-containing functional groups such as O—H and C=O and CO₂ to escape during the pyrolysis of polyester paint film. This work demonstrated that the co-pyrolysis of coke and polyester enameled wire can further promote the pyrolysis of polyester enameled wire. It can not only contribute to reduce energy consumption, but also further promote the development of copper recovery from waste enameled wires by pyrolysis method.更多还原
