摘　　要：以粉藤为研究对象,大分子量酚醛树脂、小分子量酚醛树脂和纳米二氧化硅溶液为改性剂,采用真空浸渍的方法,通过对其改性处理前后主要力学的性质变化进行研究,以期为藤材基本材性研究、增强改性处理以及纳米材在藤材改性方面的利用提供基础数据。结果表明,藤材基本力学性质均有所改善,其中低分子量酚醛树脂浸渍材效果最佳,纳米二氧化硅浸渍改性材虽然在力学性质方面没有酚醛树脂浸渍材明显,但是其不可比拟的优点在工业及日常利用上具有重要意义。通过正交试验分析,确定粉藤的最佳改性工艺为浸渍材料为小分子量酚醛树脂,浸渍量为55%,固化温度是120℃,固化时间是1 h。In order to provide the basic data for the study of the basic material properties, the reinforcement modification treatment and the utilization of the nanomaterials in the rattan modification. Calamus sp. was chosen as experimental materials and its main mechanical properties were studied before and after the modification by treated with high molecular weight phenolic resin, low molecular weight phenolic resin and nano-SiO2 solution, respectively, and vacuum impregnation method was used. The results showed that the basic mechanical properties of rattan were improved after modification, and the low molecular weight phenolic resin impregnated material is the best choice, although nano-SiO2 impregnated modified material is not as good as phenolic resin impregnated material in the mechanical properties, it has incommensurable values in working and daily life. The optimum modification process was determined by orthogonal test, and the optimal conditions were: the impregnation material, low molecular weight phenolic resin;impregnation amount, 55%;curing temperature,120℃;and curing time, 1 h.
