摘要

以毛竹为原料,在不同染色工艺条件下,研究纤维化竹单板的上染效果以及染色单板制备的竹基纤维复合材料的性能。结果表明:75℃乙醇分散介质染色与90℃水分散介质染色单板的上染色泽,均优于常温水分散介质染色;75℃乙醇染色制备的竹基纤维复合材料的色泽最佳,常温水染色时,制备材料的物理力学性能最优。综合考虑竹基纤维复合材料的表观色泽和性能,推荐使用75℃乙醇溶剂作为介质的染色工艺。

Abstract

This study investigated the influences of a dyeing treatment on color change and performance of crushed bamboo-mat composites made from Phyflostachys pubescens.Bamboo fibrosis veneers were dyed in three temperature conditions（20,75 and 90°C）and two kinds of dispersion medium（water and alcohol）.It was found that the samples dyed in alcohol at 75°C and in water at 90°C showed higher dye-uptake rates.The dyeing treatment slightly reduced MOR and MOE and improved water resistance of the composite.For better color and mechanical properties,dyeing bamboo fibrosis veneers in alcohol at 75°C was suggested.
