为提高速生材的附加值,以速生大青杨(
Populus ussuriensis
)为原料,使用不同质量分数的糠醇低聚物溶液和不同物质的量比的糠醇/丙烯酰胺改性剂处理木材,分析改性剂的分布情况以及对改性材物理和力学性能的影响。结果表明:当糠醇低聚物溶液质量分数为30%时,低聚物的分子量小于1 000,能够进入细胞壁中。糠醇改性材的尺寸稳定性较未处理材有所改善。添加丙烯酰胺后,糠醇/丙烯酰胺处理材的增重率和密度随着糠醇低聚物溶液添加量的增加而提升,抗湿胀系数可达37.51%。当糠醇与丙烯酰胺的物质的量比为4∶1时,改性材的抗弯强度为83.54 MPa,抗弯模量为14.83 GPa,冲击强度为28.64 kJ/m²,冲击强度比单独糠醇(质量分数为30%)改性材提高44.43%。添加的丙烯酰胺影响糠醇的自交联反应,降低糠醇树脂网络结构的致密程度,提高糠醇/丙烯酰胺改性材的冲击强度。
In order to add value to the fast-grown wood species
Populus ussuriensis
was selected as the raw material in this study. Differ
ent mass fractions of furfuryl alcohol (FA) oligomer solutions and varying ratios of furfuryl alcohol/acrylamide (AM) modifiers were applied to treat the wood. The distribution of the modifiers and their effects on the physical and mechanical properties of the modified wood were analyzed. The results showed that when the mass fraction of FA was 30% and the molecular weight of oligomers was less than 1 000
the modify solution entered the cell wall. The dimensional stability of furfuryl alcohol modified materials improves with the increase of FA mass fraction. After adding acrylamide
the weight gain rate and density of the FA/AM treated samples increased as the increase of AM addition. The anti-swelling coefficient reached 37.51%. When the ratio of FA to AM substances was 4∶1
the flexural strength of the modified material was 83.54 MPa
the flexural modulus was 14.83 GPa
and the impact strength was 28.64 kJ/m². The impact strength was 44.43% higher than that of the modified material with furfuryl alcohol alone (mass fraction of 30%). The acrylamide affects the self-crosslinking reaction of furfuryl alcohol
reduces the density of the network structure of furfuryl alcohol resin
and improves the impact strength of FA/AM modified materials.
