Guangxi Electrical Polytechnic Institute, Nanning 530299, China; 2. School of Civil Engineering Guangxi Polytechnic of Construction, Nanning 530007, China)Abstract： To improve the performance of high-density polyethylene (HDPE) cable protection pipes and promote the high-value utilization of artificial marble waste residues (AMWs), HDPE-based composites were prepared via melt blending and injection molding. The microstructure, crystallization behavior, mechanical properties, thermal deformation, and electrical insulation performance were systematically characterized. The results showed that the organic layer on the surface of AMWs could serve as heterogeneous nucleation sites, significantly regulating the crystallization of HDPE. At a filler loading of 50 phr, the HDPE/AMWs composites achieved a crystallinity as high as 88.5%, with a tensile strength of 23.3 MPa, which was higher than that of the CaCO 3 system at the same loading. In terms of thermal properties, the AMWs system exhibited better thermal deformation performance at low and medium filler loadings. At a filler loading of 70 phr, the CaCO 3 system showed a heat deflection temperature of 91.3 ℃ and a flexural modulus of 2 341 MPa, indicating superior resistance to high-temperature deformation and higher rigidity. Regarding electrical properties, both composite systems at a filler loading of 70 phr exhibited volume resistivities above 1.60×10 13 Ω·m and stable breakdown strengths of around 22 kV/mm, meeting the insulation requirements for cable protection pipes. In conclusion, AMWs can enhance the tensile strength and thermal stability at low and medium filler loadings through induced crystallization, while maintaining good insulation performance. This demonstrates their potential to replace CaCO 3 in the preparation of high-performance cable protection pipe materials.Keywords： AMWs; CaCO 3 ; HDPE; Cable protection pipe; Electrical properties收稿日期Submitted date 2025-12-28；修回日期Revised date 2026-01-16；录用日期Accepted date 2026-02-06基金项目：2023 年度广西高校中青年教师科研基础能力提升项目（2023KY1348）；2024 年度广西职业188宝金博页面版教学改革研究项目（GXGZJG2024B066）*联系人，bay624@qq.com引用本文：张振宇,韩绪鹏,贝慧婷.电缆保护管用HDPE/AMWs复合材料的制备与性能研究[J].塑料科技,2026,54(8):101-106.Citation：ZHANG Z Y, HAN X P, BEI H T.
