杉木间伐材ACQ防腐与综合强化复合改性研究

Study on the Compound Modification of ACQ Preservative and Reinforce of Cunninghamia lanceolata

在将ACQ与UF树脂调制成相容的复合改性剂对杉木间伐材进行复合改性研究的基础上,深入探索复合改性的机理与综合效果。对浸渍材与表面密实化处理相结合的优化工艺,当弦向压缩率为20%时各项力学性能指标均比素材增加51%以上;进行浸渍处理与ACQ或UF单独处理材经煮沸和抗水、酸、碱抽提的抗流失性对比试验及防腐试验,表明前者比后者有所提高;并采用铜离子跟踪法进行X-射线荧光光谱仪定量分析,测定了浸渍材复合改性剂的含量和分布情况,确认了一次性浸渍优化工艺参数的较佳效果。

On the base of a study by author, a new kind of environmental compound modifying agent was studied which was a solution consisting of the ACQ preservative and friendly UF. Impregnated by the vacuum, pine thinning wood could be preservative and reinforced. Mechanism and effect of compound modification were studied more intensively. When the soaked wood was carried on superficial densely processing with the compression ratio 20%, all indexs above mentioned increased above 51% compared to the control samples. The soaking material and the ACQ soaking material were respectively carried on boil the anti-draining contrast experiment and the anti-water, the acid, the alkali extracts, indicated which its processing material had the enhancement compare with alone the soaking ACQ processing material. With tracing on the cupric ion by the X-ray fluorescence spectroscope, content and the distribution of compound modifier was determined cupric ion tracing method might serve for the online examination of the production process.
