针对木塑复合材料材料的低附加值,结合碱土铝酸盐与传统木塑制备了发光型木塑复合材料,既赋予了材料特殊性能的同时,也解决了碱土铝酸盐的耐候性差、易水解的问题。采用正交试验研究分析了材料的力学性能、发光性能,并结合扫描电子显微镜与稳态荧光光谱分析材料间内部结合与发光性能之间的关联。结果表明,发光型木塑复合材料的最佳工艺参数为:聚丙烯(PP)含量为70 %、余料比例为1∶1.5、偶联剂含量为1.5 %、热压时间为10 min;拉伸强度和冲击强度最大能够达到22.2 MPa和12.55 kJ/m~2;发光型木塑复合材料的最佳激发区均在380~450 nm之间,完全覆盖发光盐的最佳激发波段400~440 nm,激发波段广,适用范...

Aiming at improving the additional value of traditional wood plastic materials,a novel type of luminescent wood plastic composites(WPC)was prepared by a combination of alkaline earth aluminate and conventional WPC.Such a combination not only endowed the material with special properties,but also solved the problems such as poor weather resistance and the easy hydrolysis of alkaline earth aluminate.The mechanical and luminescent properties of the luminescent WPC were investigated.The relationship between the internal bonding and the luminescent p...
