摘　　要：目的制备并研究缓蚀型玉米秸秆纤维发泡包装材料的性能。方法以廉价环保易得的玉米秸秆纤维、废纸纤维和气相缓蚀剂为原料,添加适量的成膜剂、胶黏剂、发泡剂、交联剂等,以微波发泡的方式制备玉米秸秆纤维缓蚀缓冲包装材料。对材料的静态缓冲性能进行测试分析,得到此缓冲材料缓冲性能的基本特征,通过密闭空间定量评价方法对材料的缓蚀性能进行测定。结果微波发泡不仅使材料存在较多的储能空间而且缓蚀效果增强,添加由二甲基咪唑啉、尿素和硼砂以质量比4∶1∶2复配的缓蚀剂后,发泡材料的缓蚀效果可达90%以上,而不添加缓蚀剂的纤维发泡材料会加速金属腐蚀。结论此发泡材料具有良好的缓冲性能与缓蚀性能,基于目前的研究进展,提出了通过改变发泡剂和粘合剂用量达到对缓蚀剂进行控释的构想。To prepare and study a new type of environment friendly volatile corrosion inhibition（VCI） packaging material and its characteristics. The light, environment friendly and inexpensive waste paper fiber, corn straw stalk fiber and volatile corrosion inhibitor were chosen as raw materials. After addition of appropriate amount of film-forming agent,adhesive, foaming agent and crosslinker, the corrosion-inhibiting and cushioning packaging material of corn straw stalk fiber was produced using the microwave foaming method. The static cushioning properties of the material was tested and analyzed in order to get the basic cushioning characteristics of the cushioning materials. The corrosion inhibition ability was tested by the confined space quantitative evaluation method. Microwave foaming did not only provide the material with more storage space, but also enhanced the corrosion inhibition properties. After addition of corrosion inhibitor made of PDMBI, carbamide and borax compounded with the ratio of 4∶1∶2, the corrosion inhibition rate of the foaming fiber materials reached more than 90%, while the fiber foaming material without VCI accelerated metal corrosion. The foamed material had good cushioning and corrosion inhibition properties. In addition, based on the research progress, this paper put forward that the release of corrosion inhibitor might be controlled by changing the dosage of foaming agent and adhesive.
