Modified corn straw flame-retardant degradable foam material and preparation method thereof

The invention provides a foaming material prepared from modified corn straw. The foaming material prepared from the modified corn straw can be naturally degraded. The problem of flammability of the foaming material produced from the corn straw at present is solved by esterification grafting modification of the corn straw, and the foaming material has good compression resistance and high rebound rate. The modified corn straw foaming material has good comprehensive application performance, can be popularized and applied in buffering, shock-proof, fire-proof and heat-insulating packaging materials, and has practical significance for comprehensive utilization of agricultural waste straw. 本发明提供了一种由改性玉米秸秆制备的发泡材料。由改性后的玉米秸秆制备的发泡材料可自然降解，通过对玉米秸秆进行酯化接枝改性解决了目前玉米秸秆生产的发泡材料易燃的问题，并且具有良好的抗压性能和高回弹率。该改性玉米秸秆发泡材料综合应用性能好，可在缓冲防震、防火隔热包装材料方面推广应用，同时对农业废弃物秸秆的综合利用具有现实意义。
