摘　　要：采用声化学法制备得到纤维素微/纳米纤丝,将其作为改性剂改善三聚氰胺浸渍纸饰面材料的热学性能和表面耐磨性。结果表明:纤维素微/纳米纤丝的添加导致DSC图谱上在150℃之后出现第3个吸热峰,且以其添加量为15%时的峰面积最大,说明它与三聚氰胺浸渍液反应过程热焓最大。并且纤维素微/纳米纤丝添加量为15%时,三聚氰胺浸渍纸饰面材料的耐磨性显著提高。傅里叶红外图谱表明,纤维素微/纳米纤丝已经进入三聚氰胺甲醛树脂体系。Cellulose miero/nano fibrils were prepared by sonoehemistry method and were used to modify melamine formaldehyde resin （MF）. Thermal and abrasion resistance properties of MF before and after modification were evaluated. The resuhs showed that the adding of fibril resuhed in the third absorption peak after 150℃ in the differential scanning calorimetry （DSC） spectrum. When the fibril loading was 15% , the maximum area of this peak was observed, indicating the maximum enthalpy of the fibril -MF reaction. The abrasion resistance was found improved significantly with the same fibril loading. The Fourier transform infrared spectroscopy （FTIR） analysis showed that the cellulose micro/nano fibrils had been integrated into the MF system.
