摘要

通过调控糠醇树脂处理液的质量分数，制备不同增重率（WPG）的糠醇树脂改性竹材，研究增重率对改性竹材尺寸稳定性、吸水率、表面润湿性、抗弯强度和弹性模量、热降解性能等的影响。结果表明，随着增重率的增加，改性竹材吸水率和接触角呈先快速降低、后降幅变缓的趋势；抗胀缩系数（ASE）逐渐增大，当增重率达到20%以后，增大趋势变缓；竹材抗弯强度下降，弹性模量小幅升高；改性竹材残炭率增大，且增重率与残碳率呈现较好的线性相关性。因此，可通过合理控制糠醇树脂改性竹材的增重率，调控糠醇树脂改性竹材的综合性能。

Abstract

In this study, the modified bamboo with a battery of weight percentage gain (WPG) was prepared by controlling the mass fraction of the furfuryl alcohol resin solution. The effect of WPG on the dimensional stability, the water absorption, the surface wettability, mechanical properties, and the thermal stability of modified bamboo were evaluated, respectively. With the increase in WPG, results indicated that the water absorption and contact angles of bamboo significantly decreased at the initial stage, then gradually slowed down the decreasing process. The anti-swelling efficiency (ASE) value increased and gradually become flat when the WPG was higher than 20%. An reduction in the modulus of rupture was observed, while the modulus of elasticity slightly increased. The residue carbon weight ratio increased and had a linear correlation with the WPGs. It was feasible to improve the comprehensive properties of modified bamboo by managing the WPGs reasonably.
