摘要
本论文主要以毛竹(Phyflostachys pubescens)为研究对象,以水、醇为介质,采用不同工艺对纤维化竹单板进行染色处理后,以浸渍型酚醛树脂为胶黏剂制备重组竹板材,通过对染色处理后纤维化竹单板制备的竹基纤维复合材料进行室外自然老化的研究,探讨室外自然老化与材料表面颜色及尺寸稳定性的关系,揭示在室外老化环境下竹基纤维复合材料性能随时间变化的规律。研究表明:竹基纤维复合材料经过3个月的室外自然老化试验过程后,、随着气候条件的变化,材料表面色泽出现缓慢衰减趋势,宽度损失率、厚度损失率、质量损失率随着气候变化具有类似增减趋势,醇染材料的宽度、厚度、质量损失率均高于水染材料。
In this paper, Phyflostachys pubescens bamboo fiber bundles dye-treated with different method were chosen as basic raw materials, and then reconstitued with phenol-formaldehyde adhesive and hot pressing process. The properties of dye-treated bamboo-based fiber composite after outdoor aging test were analyzed, the relationship between outdoor aging test time and surface color, dimensional stability, weight loss rate were also discussed. According to the study, we found that the bamboo-based fiber composites after 3 months outdoor aging test, the change of color, ΔL＊,Δa＊,Δb＊ value was declined gradually after the increase of the outdoor aging test time. Dimensional stability, weight loss rate changed differently as the climate conditions and highly changed similar with the analysis, respectively.
