中文摘要:
      探索了以偶联剂和碱复合处理的方法对秸秆进行表面改性处理的工艺,开展了以秸秆和木刨花(木材加工剩余物)为主要原料制备包装行业用秸秆刨花板的研究,重点考察了不同预处理条件对麦秸秆表面性能的改善情况,及原料中秸秆/ 木刨花比对制备的刨花板性能的影响规律。实验结果显示,秸秆表面预处理最佳条件是KH-550 用量为3%、改性时间为90 min、改性温度为60 ℃,秸秆刨花板中秸秆用量的增加将会导致秸秆刨花板弹性模量、静曲强度下降,吸水膨胀率增大和氧指数降低。偶联剂与碱复合处理比单一处理对秸秆表面胶合性能的改善更明显,秸秆使用量的提高会导致刨花板性能下降。
英文摘要:
      The development of straw particleboard is the direction and key point of wood reduction and substitution in packaging industry. Wheat straw was pretreated with coupling agent and alkali composite treatment to modify its adhesive properties. Straw particle board was prepared with the pretreated straw and wood shavings. The effects of different factors on straw pretreatment and the ratio of straw/ shavings on properties of straw particle board were studied. The results showed that the optimized pretreat condition is the usage of KH-550 3%, modification time 90 min, and temperature 60 ℃; elasticity modulus, static bending strength, and oxygen index decrease, while the expansion rate of water absorbing of the straw particle board increase, with the increase of straw/ shavings ratio. It was concluded that composite treatment of coupling agent and alkali has more obvious improvement than single treatment; increase of straw usage amount will cause the performance fall down of straw particle board.
