摘　　要：以秸秆水解生产燃料乙醇的残渣(ER)、尿素(U)、甲醛(F)和三聚氰胺(M)为原料,制备了秸秆乙醇残渣三聚氰胺脲醛(ERMUF)树脂。分别考查了U、M、ER用量对制备的ERMUF树脂的性能及其制备三合板性能的影响。确定了反应的最优原料配比为n(F)/n(U)为1.5,n(M)/n(F)为0.15,m(ER)/m(ER+U)为0.48,在该条件下得到的ERMUF树脂制备的三合板的胶合强度1.03 MPa,满足国家II类板要求,甲醛释放量0.24 mg/L,满足E0级要求。探讨了固化体系对ERMUF树脂固化性能的影响,选出了适宜的固化体系为NH4Cl和H3PO4复合固化剂,用量分别为1%和0.5%,此条件下ERMUF树脂的固化时间较短148 s,胶合强度较高为1.09 MPa,甲醛释放量为0.25 mg/L。The straw ethanol residue-melamine-urea-formaldehyde（ ERMUF） resin was prepared with straw ethanol residue（ ER）,melamine（ M）,urea（ U） and formaldehyde（ F）. The effects of the contents of ER,M and U on the performance of ERMUF resin and the three-plyboard were studied. The optimal raw material ratios were n（ F） / n（ U） 1. 5,n（ M） / n（ F） 0. 15 and m（ ER） / m（ ER ＋ U） 0. 48. The formaldehyde emission from three-plyboards prepared with the ERMUF resin obtained under these above ratios was 0. 24 mg / L and met E0 grade. The bonding strength was 1. 03 MPa and met the requirement of typeⅡplyboard.The curing behavior of ERMUF resins with different curing agents was also investigated. The results showed that the combination of NH4Cl and H3PO4 gave good curing performance and the suitable dosages of additions were 1 % NH4Cl and 0. 5 % H3PO4. The corresponding curing time of ERMUF resin was short（ 148 s）,the bonding strength of three-plyboard was srtong（ 1. 09 MPa） and the formaldehyde emission was 0. 25 mg / L.
