摘要
对黄麻韧皮进行微波辅助碱液(NaOH)处理,再利用硅烷偶联剂KH550对黄麻纤维表面进行修饰。将处理过的黄麻纤维短切后混入聚氨酯发泡剂来制备黄麻增强聚氨酯发泡板材。结果发现,微波辅助处理后黄麻纤维表面粗糙度增加,当纤维质量分数为2.5%时,制备的发泡板材的压缩强度达到峰值;当纤维长度为2mm时,制备的复合材料的压缩强度最高。
Jute bast was treated with alkali solution(NaOH) assisted by microwave, and silane coupling agent(KH550) was used to modify the surface of the treated jute fibers. Then the modified jute fiber was cut and filled in polyurethane foaming agent to prepare jute reinforced polyurethane foamed sheet. Through the related experimental analysis, it was concluded that the surface roughness of the jute fiber increased after microwave-assisted treatment. When the fiber mass fraction was 2.5%, the compressive strength of the prepared foamed sheet reached the peak. As the fiber length was 2 mm, the compressive strength of the prepared composite was the highest.
