| 目的 研究竹纤维/淀粉发泡复合缓冲材料的制备方法， 分析组分含量变化对发泡材料力学性能的影响规律， 确定最佳的组分配比和最佳配比条件下竹纤维/淀粉发泡复合材料的能量吸收性能。方法 将按一定比例配置的竹纤维、 淀粉、 碳酸氢铵、 丙三醇和水置于模具中， 采用烘焙发泡法制备竹纤维/淀粉发泡复合材料， 并从能量吸收的角度分析了发泡剂、 胶黏剂、 增塑剂对竹纤维/淀粉复合发泡材料缓冲性能的影响规律， 从而确定各组分的最佳配比。结果 随着发泡剂和淀粉含量的增加， 竹纤维/淀粉发泡复合材料的平台应力和总吸收能量呈现出先增加后减小的趋势， 增塑剂含量的增加可改善制品的弹塑性， 但降低了制品的平台应力和能量吸收能力； 竹纤维、 淀粉、 水、 碳酸氢铵、 丙三醇最佳质量比为1∶2∶3∶1∶0.8。结论 最佳质量配比条件下的竹纤维/淀粉发泡复合材料具有一定的缓冲吸能效果， 其静态缓冲性能与EPS接近， 可用于产品的物流防护。 |

| Preparation and performance of bamboo fiber/starch foam composites were studied in this paper. The influencing law of different component contents on the mechanics and properties of the foam materials was analyzed, in order to determine the energy absorption performance of bamboo fiber/starch foam composites prepared under the optimal composition and conditions. Bamboo fiber, starch, ammonium bicarbonate, glycerol and water were mixed at a certain ratio to prepare bamboo fiber/starch foam composites using baking foaming method, and the influencing law of the contents of foaming agent, starch and plasticizer on the performance of the bamboo fiber/starch foam materials was explored from an energy absorption standpoint, thus the optimal foaming condition was determined. With increasing foaming agent and starch contents, the plateau stress and total energy absorption capability showed a tendency of first increasing and then decreasing. The increasing content of plasticizer could improve the plasticity of the product, but reduce the plateau stress and energy absorption capability of the product. The optimal ratio of bamboo fiber∶starch∶demonized water∶ammonium bicarbonate∶ glycerol was determined to be 1∶2∶3∶1∶0.8. The bamboo fiber/starch foam composites prepared under the optimal condition had a certain cushioning energy absorption capacity, and its static cushioning performance was similar to that of EPS. Therefore, the composites could be used in logistics protection of products. |
