采用真空浸渍法制备环氧树脂填充微波膨化樟子松木材，探讨环氧树脂填充前后微波膨化樟子松的微观形貌、化学结构、热稳定性和力学性能的变化规律。结果表明：环氧树脂主要填充在微波膨化樟子松的宏观裂缝及其相邻的若干个细胞腔内，少量填充在晚材细胞腔内，并在微波膨化樟子松内部形成部分连通的高分子树脂骨架结构；微波膨化樟子松经环氧树脂填充后，体积增大1.61%，密度增加97.37%，热稳定性提高（,T,-5%,分解温度提高了23.18 ℃，最大分解速率提高了11.08 ℃）；环氧树脂填充微波膨化樟子松的硬度、抗压强度、弹性模量和静曲强度等力学性能指标，较樟子松素材分别提高了34.38%、48.74%、12.96%和11.38%，环氧树脂填充微波膨化樟子松同时具有良好的纹理。本研究为人工林木材的整体化、实木化应用提供了新思路。
The microwave puffed Mongolian scotch pine samples were impregnated with the epoxy resin in a vacuum environment. The changes of the morphology, chemical structure, thermal stability, and mechanical properties of the samples before and after the filling were investigated. The results showed that the resin was mainly filled in the macroscopic cracks and several cell lumens on both sides of the puffed wood. A small amount of resin was filled in the cell cavities of the late wood. A partially connected polymer resin skeleton structure was formed in the puffed wood. After being filled with the epoxy resin, the volume of microwave puffed samples increased by 1.61%; the density increased by 97.37%; the thermal stability was improved; T,-5%, decomposition temperature increased by 23.18 ℃; the maximum decomposition rate increased by 11.08 ℃; the hardness, compressive strength, elastic modulus, and the static intensity increased by 34.38%, 48.74%, 12.96%, and 11.38% higher than control sample, respectively. Microwave puffed Mongolian scotch pine wood filled with epoxy resin also had good aesthetic textures. This study provides a new idea for the integrated application of the plantation wood.
