马尾松(Pinus massoniana Lamb)木材是我国南方的重要结构用材,但是它易受真菌和害虫的侵害,以及当这种木材中水分含量发生变化时其尺寸容易发生变化,致使其用途受到限制。本研究试图用低聚酚醛树脂来浸注木材,以提高其抗腐力、尺寸稳定性和其它机械强度。试验室试验表明改性材具有优良的抗腐性能和尺寸稳定性,其它力学性能也有明显的改善。 Pinus massoniana Lamb wood is an important structural material in southern China, but it is susceptible to fungi and pests and its size is subject to change as the moisture content in such wood varies. This study attempted to impregnate wood with oligomeric phenolic resins to improve its corrosion resistance, dimensional stability and other mechanical strengths. Laboratory tests show that modified wood has excellent corrosion resistance and dimensional stability, and other mechanical properties have also been significantly improved.
