紫外光照对不同色系木塑板颜色指标的影响
The Effect of UV Light on the Color Index of Different Color Wood Plastic Panels
摘要
Abstract
This paper explores the behavior and mechanisms of wood-plastic composites(WPC)aging applications.Through the aging mechanism of wood-plastic composites and ultraviolet light aging experiments,focusing on the impact of ultraviolet light irradiation on the color performance of different color composite panels,the study explored the color index of composite panels with the accelerated aging time of the rule of change.The results showed that the standard WPC after 240h UV irradiation,the color difference ΔE value increases to different degrees,the most significant change in total color difference value in silver-gray WPC board was noted as 2.82.However,change in total color difference value of black WPC board was observed as more stable with an increase of 0.77 in total color difference value.Additionally,the color difference value ΔE of co-extruded WPC was more stable,as the total color differences of various color types of wood-plastic panel was less than 1.12.The co-extruded wood-plastic composites(WPC)showed superior resistance to UV-induced color change compared to standard WPC,indicating the positive effect of the polyethylene shell layer in resisting aging.关键词
