摘要

为改善马尾松木材的性能,采用低分子量酚醛（PF）树脂对其进行浸渍改性处理,考察了树脂不同的固体含量对马尾松性能的影响。结果表明:处理马尾松试样的密度增大,尺寸稳定性、静曲强度、弹性模量和硬度均有不同程度的提高,冲击韧性降低。

Abstract

Pinus massoniana lumber was impregnated with low molecular weight phenol formaldehyde resins,with different solids contents,to improve its physical and mechanical properties.A vacuum-pressure process was used to impregnate the lumber.The results showed that dimensional stability,modulus of rupture,modulus of elasticity and hardness of the test samples were all increased after impregnation with different concentrations of PF resin from 10%to 30%.However,toughness of the samples decreased as the resin weight gain increased.
