电气石/木材复合材制备及微观结构分析

Preparation of Tourmaline/Wood Composite Material and Microcosmic Structure Analysis

电气石具有释放负氧离子等特殊功能,可以改善环境质量以及促进各种产品的功能化。本研究将电气石以浸渍的方式引入木材中,通过树脂固化的方式将其固定于木材内部,从而得到具有释放负氧离子的功能性木质材料。利用满细胞法,经MUF处理,电气石浓度在5%,偶联剂浓度为4%,浸渍时间为60 min,木材浸渍增重率达到36.9%且分布均匀,负氧离子释放量约为1 086个/cm^3。PEG处理材流失率为15.7%,MUF浸渍处理材的流失率仅为1.3%。

Tourmaline has the special function of releasing negative oxygen ions,it can improve environmental quality and promote the functionalization of various products.Therefore,authors of this paper introduce tourmaline into wood by soaking and fixed into the wood by resin curing.Through full cell process,wood materials with negative oxygen ion release function are obtained.Impregnation by MUF for 60 minutes with tourmaline(5%)and coupling reactant(4%),the impregnation rate of wood reached 36.8%and the distribution was even,the negative oxygen ion release was about 1 086 ions/cm3.The leachability of PEG treated materials was 15.7%and that of MUF impregnated treated materials was only 1.3%.
