摘　　要：通过化学氧化 ,对麦草纤维进行表面改性。初步探索了麦草纤维表面改性的可行性 ,并对改性剂JB处理前后的麦草纤维进行了ESCA能谱分析 ,以及麦草纤维 /脲醛树脂胶中密度纤维板 (MDF)的性能测试。结果表明 ,所采用的改性方法 ,提高了麦草纤维表面的极性和反应活性 ,用改性的麦草纤维制得的中密度纤维板 ,其力学性能有显著提高。The surface of wheat straw fiber is modified by means of chemical oxygenation method and the probability of the surface modification on wheat straw fiber was explored in this work. The treated wheat straw fiber with modifier JB and untreated fiber were analyzed by ESCA and the mechanical properties of wheat straw MDF(medium density fiberboard) were measured. The results show that the polarity and reactive activity of the surface of wheat straw fiber are improved by the modification, as well as the mechanical properties of MDF with modified fibers.
