摘要

摘要: 功能性光致变色木塑复合材料(PWPC)使用寿命通常较短，因此本研究将抗氧剂1010和光稳定剂770引入到PWPC中，以改善复合材料的力学和耐光疲劳等性能。采用熔融共混法制得杨木粉/聚乳酸(WF/PLA)基光致变色复合材料，通过熔融沉积技术(FDM)打印成型，对制备的WF/PLA复合材料力学、界面相容性、热稳定性和耐光疲劳性能进行分析表征。与WF/PLA复合材料相比，当只添加抗氧剂1010时，WF/PLA复合材料拉伸、弯曲和冲击强度分别提高了42.58%、23.25%、6.52%；只添加光稳定剂770时，WF/PLA复合材料拉伸强度提高，弯曲强度和冲击强度均下降。当抗氧剂1010与光稳定剂770以质量比为1∶1添加到WF/PLA复合材料中时，在这两种助剂的协同作用下，WF/PLA复合材料的拉伸强度提高了1.8%，弯曲和冲击强度分别减小了9.3%和22.1%，相比于其他复配体系样品，力学性能降低幅度最低。此外，与WF/PLA复合材料相比，抗氧剂1010与光稳定剂770质量比为1∶1的WF/PLA复合材料的热降解性能和耐光变疲劳性能得到改善，质量损失为5%时的温度为219.84℃。老化第10天，其表面颜色变化值ΔE由5.3增至6.7，增加了26.7%。

Abstract: Functional photochromic wood-plastic composites (PWPC) have great application potential in interior decoration and other fields. However, the lifespan of PWPC is usually short. In this paper, antioxidant 1010 and light stabilizer 770 were introduced into PWPC to improve the mechanical properties and photofatigue-resist of composites. The wood flour/polylactic acid (WF/PLA) based photochromic composites were prepared via melt blending and printed by fusion deposition technology (FDM). The mechanical properties, interfacial compatibility, thermal stability, and photofatigue-resist of WF/PLA composite were then characterized. The results show that when antioxidant 1010 is added alone, compared with WF/PLA composite, the tensile, flexural and impact strength of composite increased by 42.58%, 23.25% and 6.52%, respectively. However, adding light stabilizer 770 alone, the tensile and flexural strength increase while the impact strength decreases. When antioxidant 1010 and light stabilizer 770 are added to WF/PLA composite at mass ratio of 1∶1, the tensile strength of composite increased by 1.8% under the synergistic effect of these two additives, the bending and impact strength decreased by 9.3% and 22.1%, respectively. Compared with other combinational systems, the decrease in mechanical properties is the lowest. In addition, WF/PLA composite with mass ratio antioxidant 1010 to light stabilizer 770 of 1∶1 has better thermal degradation properties and photofatigue-resist than WF/PLA composite. The temperature at mass loss of 5% is 219.84℃. On the 10th day of aging, the surface color difference ΔE of WF/PLA composite increased from 5.3 to 6.7, increase of 26.7%.
