摘　　要：以前期研究成果盾粉为研究对象,采用熔融共混与热压相结合的工艺,将不同化学成分的盾粉替代50%滑石粉与聚乙烯复合制备盾粉/木塑复合材料。利用X射线射仪(XRD),傅里叶红外光谱仪(FTIR),扫描电子显微镜(SEM)进行表征分析,同时使用熵权-灰色关联分析法分析盾粉化学成分对盾粉/木塑复合材料力学性能的影响。研究结果表明,具有多孔结构的盾粉,其比表面积大,吸附性好,使其被马来酸酐接枝聚乙烯(MAPE)包裹,马来酸酐基团能够与盾粉表面的—OH发生酯化反应,生成稳定的化学键,增强了界面相容性。盾粉化学成分对盾粉/木塑复合材料拉伸强度的综合关联度排序为CaO(氧化钙)>Fe_(x)O_(y)(铁氧化合物)>MnO(氧化锰)>P_(2)O_(5)(五氧化二磷)>SiO_(2)(二氧化硅)>MgO(氧化镁)>Al_(2)O_(3)(三氧化二铝)>SO_(3)(三氧化硫);盾粉化学成分对盾粉/木塑复合材料弯曲强度的综合关联度排序为CaO>Fe_(x)O_(y)>MnO>P_(2)O_(5)>SiO_(2)>MgO>Al_(2)O_(3)>SO_(3);盾粉化学成分对盾粉/木塑复合材料冲击强度的综合关联度排序为CaO>Fe_(x)O_(y)>P_(2)O_(5)>MnO>SiO_(2)>Al_(2)O_(3)>MgO>SO_(3)。说明盾粉中CaO,Fe_(x)O_(y)是提高盾粉/木塑复合材料力学性能的主要成分,而SO_(3)则对性能提高起负面影响。为盾粉的配方设计提供了明确的优化方向,即提高CaO和Fe_(x)O_(y)含量,并减少SO_(3)含量,以提升木塑复合材料的整体力学性能。Taking the shield powder of the previous research results as the research object,the shield powder/wood-plastic composites were prepared by replacing 50%talc in the polyethylene composites with shield powders using a combination of melt blending and hot pressing processes.Shield powders possess with different chemical compositions.X-ray radiography(XRD),Fourier infrared spectroscopy(FTIR),scanning electron microscope(SEM)were used for characterization and analysis,and at the same time entropy weight-gray correlation analysis method was used to analyze the effects of the chemical compositions of the shield powders on the mechanical properties of the shield powder/wood-plastic composites.The results show that the shield powders with porous structures have the large specific surface area and good adsorption,which makes shield powders wrapped by maleic anhydride grafted polyethylene(MAPE).The maleic anhydride groups could esterify with hydroxyl groups on the surface of the shield powders to generate stable chemical bonds,which enhances the interfacial compatibility.The overall correlations of the chemical compositions of shield powders on the tensile strength of shield powder/wood plastic composites are as follows:CaO(calcium oxide)>Fe_(x)O_(y)(ferrites)>MnO(manganese oxide)>P_(2)O_(5)(phosphorus pentoxide)>SiO_(2)(silicon dioxide)>MgO(magnesium oxide)>Al_(2)O_(3)(aluminum oxide)>SO_(3)(sulfur trioxide).The overall correlations of the chemical compositions of shield powders on the flexural strength of shield powder/wood plastic composites are as follows:CaO>Fe_(x)O_(y)>MnO>P_(2)O_(5)>SiO_(2)>MgO>Al_(2)O_(3)>SO_(3).The overall correlations between the chemical compositions of shield powders on the impact strength of shield powder/wood-plastic composites are as follows:CaO>Fe_(x)O_(y)>P_(2)O_(5)>MnO>SiO_(2)>Al_(2)O_(3)>MgO>SO_(3).The results indicate that CaO and Fe_(x)O_(y) are the main components to improve the mechanical properties of shield powder/wood-plastic composites,while SO_(3) negatively impacts the performa
