摘要
表面润湿性是木材的一个重要界面特性,直接影响其胶合和涂饰性能。以热改性橡胶木为研究对象,利用液滴法测定阻燃处理前后蒸馏水在热改性橡胶木表面的接触角,旨在比较阻燃处理对热改性橡胶木表面润湿性的影响。结果表明,阻燃处理对热改性橡胶木的表面润湿性有显著影响,不同阻燃剂之间无显著差异。阻燃热改性橡胶木表面接触角减少,表明磷氮类复合阻燃剂可以改善木材的表面润湿性。
The surface wettability of wood is an important interfacial character of wood and directly affects the bonding and painting performance.Droplet method was used to measure the surface contact angle with distillated water before and after fire retardant treatment of thermally modified rubber wood or thermo rubber wood(TRW)in order to compare the effect of fire-retardant treatment on surface wettability of the TRW.The results showed that fire retardant treatment had significant impact on the surface wettability of the TRW,which was not significantly different among fire retardants.Compared with the control samples,the fire-retarding TRW had a small contact angle,which indicates an improvement in surface wettability of the TRW that was treated with nitrogen-phosphorus complex fire retardants.
