摘要:采用甲基三乙氧基硅烷(MTES)与正硅酸乙酯(TEOS)共水解获得改性溶胶,然后将溶胶通过真空-加压设备浸注入木材内部,并发生凝胶复合制备陶瓷化木材,解决了TEOS水解溶胶制备的陶瓷化木材脆性大、耐水性差的问题。改性凝胶具有疏水性,降低了陶瓷化木材的吸水增重率,提高了抗压和抗弯曲强度等力学性能。
Wood - ceramic composites which demonstrate some unique characteristics have attracted scientists' research attention lately. A modified sol prepared through the methyl triethoxy silane (MTES) hydrolysis process was impregnated into the wood cells with vacuum - pressure cycles. The alternate pressure cycles overcame some harriers of slow and incomplete impregnation that the previous processing method presented. The results indicate that wood - ceramic composites made with the METS modified sol through the alternate pressure cycles exhibit improved water-repellency and plasticity, and the mechanical property is also enhanced.
