中文摘要:以玉米秸秆为原料,采用微波液化产物合成可生物降解聚氨酯泡沫,替代传统石化产品多元醇制备聚氨酯泡沫。通过异氰酸根指数及发泡剂水用量对聚氨酯泡沫材料密度、机械性能的影响分析,得到优化的聚氨酯合成工艺条件:水添加量0.30g、异氰酸根指数为1.0;采用土埋法生物降解试验发现,液化产物制备的聚氨酯泡沫在埋置6个月后质量损失约18.71%,热重分析表明合成的聚氨酯泡沫热分解分为4个典型的阶段。试验结果表明玉米秸秆微波液化产物可合成环境友好可生物降解聚氨酯泡沫,但其材料性能有待进一步表征。

Abstract:With the aim to explore the efficient application of microwave liquefied product, experiment on the synthesis of polyurethane (PU) with microwave liquefied product from corn stover instead of petrochemical polyol was carried out. The optimized synthetic process of PU was 0.30g foam blowing agent and isocyanate index 1.0. The biodegradable property of the composites was investigated by means of bury test which showed 18.71% degradation rate in six months. The thermal gravimetric analysis indicated four phases in the thermal pyrolysis of PU. All the results indicated microwave liquefied product from corn stover could be used for the production of PU foam while the material property was to be characterized and improved.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
