The resource utilization of artificial marble wastes (AMWs) is urgently needed for environmental protection as a large amount of artificial marble are used as construction material. Nevertheless, it still remains challenging to achieve high performance of AMWs‐filled polymer composites due to their poor interfacial interaction with hydrophobic polyolefins. Here, the unsaturated resin residue on the surface of AMWs is employed to construct strong interfacial interaction with high‐density polyethylene (HDPE) matrix to prepare mechanically robust polymeric composites by use of titanate coupling agent. The mechanical properties (with a tensile strength of 28.6 MPa and a flexural strength of 27.7 MPa) of the resulting composites are comparable to or even better than those of raw calcium carbonate‐filled HDPE composites. This work will not only promote the recycling and reutilization of AMWs, but also provide a feasible way for value‐added application of other polymeric wastes, such as waste printed circuit board, waste artificial turf, and so on.

使用钛酸酯改善聚乙烯/人造大理石废料复合材料的界面相互作用和机械性能

人造大理石废料（AMW）的资源利用是环境保护的迫切需要，因为大量人造大理石被用作建筑材料。然而，由于AMWs填充的聚合物复合材料与疏水性聚烯烃的不良界面相互作用，要实现高性能仍然充满挑战。在这里，AMW表面上的不饱和树脂残留物被用来与高密度聚乙烯（HDPE）基质建立牢固的界面相互作用，从而通过使用钛酸酯偶联剂制备机械强度高的聚合物复合材料。所得复合材料的机械性能（抗拉强度为28.6 MPa，弯曲强度为27.7 MPa）与填充碳酸钙的HDPE复合材料相当甚至更好。
