| 摘 要： | 分析了稻秸木材复合工艺配比及防水剂的添加量(0.8%、1.2%、1.6%、2.0%)对稻秸木材复合中密度纤维板性能的影响。结果表明:采用稻秸与木材原料分别进行纤维分离,再混合后施胶的复合工艺,当草木配比为1∶1,防水剂加量为1.2%,脲醛树脂胶粘剂的施胶量为12%时,生产出的稻秸/木材中密度纤维板,除吸水厚度膨胀率外,各项性能均能达到中密度纤维板标准要求。

| Abstract: | Rice straw and wood based medium density fiberboards(MDF) were made in the lab.Three kinds of mixed methods for manufacturing straw and wood based MDF in this research were as flowers: Firstly,raw material of rice straw and wood were mixed,then were made to be fibers with urea-formaldehyde sprayed.Secondly,rice straw and wood raw material were made to be relevant fibers,then mixed with UF sprayed.Finally,rice straw and wood raw material were made to be relevant fibers,then UF was spayed and mixed.Wood to rice-straw ratio in this research was 0,10%,20%,30%,40%,50%,and 100%,respectively.The content of water repellent was 0.8%,1.2%,1.6%,and 2.0%,respectively.Results showed that with 50% wood fiber,1.2% water repellent,and 12% UF,all physical and mechanical properties of straw and wood based MDF could reach to the standard values of GB except for thickness swell. |
