秸秆乙醇残渣三聚氰胺脲醛树脂的制备与固化性能研究
P reparation and Curing P erformance of Straw Ethanol Residue-melamine-urea-formaldehyde Resin
摘要
Abstract
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 (148s), the bonding strength of three-plyboard was srtong(1.09MPa) and the formaldehyde emission was 0.25 mg/L.关键词
