摘要:
以相思单宁和大豆蛋白制备单宁-大豆蛋白胶黏剂(SFT)为研究对象,以胶合板胶合性能和耐水性能为测试指标,分析了等离子改性的杨木及松木胶合板性能。结果表明,与大豆蛋白胶黏剂相比,胶黏剂SFT胶合板胶合强度和耐水性能有明显提高,其中单宁与大豆蛋白复合交联体系的形成及邻苯二酚基团引入可能是关键因素。等离子处理后的杨木和松木表面接触角显著减小,表面能显著提高,表面润湿性能得到了很大的改善,其协同SFT制备的杨木胶合板和松木胶合板胶合强度与耐水性能显著提高,但松木胶合板性能的提升幅度要明显高于杨木胶合板。FI-IR和SEM分析表明,等离子体高能粒子在杨木和松木木材表面同时发生了物理和化学作用,前者是在木材表面形成蚀刻粗化面,后者是在木材表面产生大量的极性基团。此外,等离子体可能使油脂发生氧化降解,甚至转化成有利于胶接的成分,使得等离子改性的松木胶合板性能提升幅度高于杨木胶合板。
Abstract:
Tannin-soy based adhesive (SFT) was prepared with acacia tannin extract and soy protein, and properties of plasma modified poplar wood and pine wood were studied by the investigation of bonding strength and water resistance of plywood with SFT in this paper. The results indicated that bonding strength and water resistance of plywood with SFT improved obviously than that of soy-based adhesive, and crosslinking system formation of tanin-soy based adhesive and introduction of catechol groups may be the key. After plasma treating on surface of poplar wood and pine wood, contact angle decrease, surface energy increase, and wettability was improved. The bonding strength and water resistance of plywood combination plasma with SFT were significantly improved, and the increasing degree of pine-plywood was higher than poplar-plywood greatly. FT-TR and SEM results showed that the physical and chemical action happened on the wood surface after plasma treatment. Plasma could produce active groups on wood surfaces by the degradation of fiber and lignin of wood, and the wood surface was etched from the smooth into the coarse. In addition, the fats might oxide and degrade to some degree, and converted into what was conducive to adhesive and adhesion, which led to performance improvement of pine-plywood than that of poplar-plywood.
