The invention belongs to the technical field of high polymer material processing, and particularly relates to a preparation method of hydrogenated C9 petroleum resin coated polyester/chinlon/spandex modified HDPE. The C9 petroleum resin is utilized to coat the polyester/chinlon/spandex mixed material, and the compatilizer is added, so that the problem of poor compatibility and dispersibility of the polyester/chinlon/spandex and HDPE is effectively solved, the polymer composite material with excellent comprehensive mechanical properties is finally prepared, and the polymer composite material has wide application value. Meanwhile, a solution is provided for recycling of materials such as waste polyester/chinlon/spandex, the utilization efficiency is improved, secondary pollution is reduced, and sustainable development of people and nature is achieved. 本发明属于高分子材料加工技术领域，具体涉及一种加氢C9石油树脂包覆涤纶/锦纶/氨纶改性HDPE的制备方法。本发明利用C9石油树脂包覆涤纶/绵纶/氨纶混合材料，并通过添加相容剂，有效解决涤纶/锦纶/氨纶与HDPE相容性及分散性差的问题，最终制备出了综合力学性能较优的高分子复合材料，具有广泛的应用价值。同时也为废旧涤纶/锦纶/
