The effects of the contents of maleic anhydride grafted polyolefin elastomer (POE-g-MAH) and resin lens powder on the mechanical properties of low density polyethylene (LDPE) /resin lens powder/ POE-g-MAH composites were investigated, and the compatibility of the composites was studied. The mechanical tests showed that POE-g-MAH significantly improved the impact strength of the composites. It was found that the tensile strength of the composite increased with the increasing of resin lens powder content, and the impact property of composites achieved the best when the amount of resin lens powder quality was 100 percent. FT-IR spectra showed that there was an esterification reaction happened in the LDPE/resin lens powder/POE-g-MAH blend. The results of SEM revealed that the composite with the addition of POE-g-MAH as a compatibilizer had better compatibility of interface.%考察了乙烯-辛烯共聚物接枝马来酸酐(POE-g-MAH)、树脂镜片磨屑粉用量对低密度聚乙烯(LDPE)/树脂镜片磨屑粉/POE-g-MAH复合材料的力学性能的影响,并研究了共混体系的相容性.力学性能测试表明,POE-g-MAH加入提高了复合材料的抗冲击性能；LDPE/树脂镜片磨屑粉/POE-g-MAH复合材料的拉伸强度随着树脂镜片磨屑粉用量增加而上升,冲击强度在树脂镜片磨屑粉用量为100份时达到最大值.红外光谱表明,POE-g-MAH与树脂镜片磨屑粉共混时发生酯化反应.电镜观察揭示了用POE-g-MAH增容的复合材料有更好的界面相容性.
